Condensation Solving Loft Unit
Nuaire Drimaster Eco Heat
For homes with lofts – Whole House Condensation Control
The unique DRI-ECO-HEAT-HC incorporates all of the functions of our DRI-ECO-LINK-HC unit but with the benefit of an integral heating element, located between the flexible duct and ceiling diffuser.
This heating component will temper the air which is distributed through the property via the ceiling diffuser, thus ensuring a comfortable living environment. This pioneering design sees the low watt heater (400w) react efficiently and effectively, guaranteeing an economically friendly product.
A temperature sensor on the outside of the unit monitors and controls the heater output to maintain the set point. The set point ranges from 5° to 15° and can be adjusted from the ceiling diffuser. If the temperature at the heater outlet is above the set point, the heater will not activate.
Please note, it is not possible to retro-fit a heater to other Drimaster Eco models.
The DRIMASTER-ECO range provides whole home ventilation using the Positive Input Ventilation principle, which introduces fresh filtered air into the dwelling at a continuous rate, encouraging movement of air from inside to outside.

NUAIRE INVENTED PIV OVER 40 YEARS AGO
It has become the UK’s most popular alternative method of low energy, cost-effective ventilation!
Invented by Nuaire and installed in thousands of dwellings each year, PIV can be a more cost-effective and simple to install ventilation solution, whilst still meeting building regulations.
CREATES A HEALTHY LIVING ENVIRONMENT
MOISTURE AND CONDENSATION ARE DRIVEN OUT
The filtered air gently pressurises the home from inside out, forcing out the stale air.
NO NEED TO OPEN WINDOWS TO VENTILATE
Clean, fresh air is continuously drawn in through the lofts natural leakage points, passed through the filters and fed into the property via a central hallway diffuser.
Powerful Filters (Nox version only)
Two ePM10 filters are mounted on the side of the unit and incorporate an additional carbon filter in each, giving the highest quality filtration system available to any DrImaster unit, and significantly outperforming other market-leading PIV units.
Carbon pellets within the filters absorb harmful pollutant chemicals such as Nitrogen Dioxide and Nitrogen Oxide commonly associated with busy built-up areas. The filters have been proven to reduce the levels of these chemicals found within the home by up to 80%.
The efficiency of the filters has been stringently tested by the BRE and shows a proven benefit to indoor air quality.
INSTALLATION INSTRUCTIONS
Always get a qualified electrician for fitting the unit!
The unit is supplied with a pre-wired power supply. This power supply unit has a metal bracket incorporating fixing holes, which should be used to fit the power supply to a suitable surface, e.g. a wooden joist.
(Please note, brackets to mount the Drimaster to wooden loft beams are not included.)
The fan unit is also supplied with a fused spur. The 3 core mains cable from the power supply should be connected to a fixed wiring installation, via the isolator, via the spur, in accordance with current IEE wiring regulations.
- To install the diffuser, cut out a section of the ceiling in the central position of your landing hallway. If possible, at least 1m away from a smoke alarm or CO2 monitor.
- In the loft cavity, mark the centre point between two joists, and drill a hole in the centre point.
- Using the diffuser template provided, line up the centre point, and mark out the section to be cut out of the ceiling.
- 4. Cut out the section of ceiling ready for the diffuser, then fit the diffuser into the hole, and secure with the screws and plasterboard plugs provided.
- Once the diffuser is secured, fit the ducting over the heater and over the screws, then attach the supplied cable tie below the screws to secure the duct to the heater.
- Connect the data cable to the diffuser interface panel, then the heater to the diffuser.
- Attach the ducting to the fan, and secure using a cable tie.
- Fix a screw to a convenient joist near the diffuser. If possible, suspending the unit approx 2/3 of the loft height to capitalise on solar gain, making sure the duct is not overstretched.
- Ensure that the filters are fitted securely.
- When the unit is in position, connect the data cable from the heater to the unit, then the heater mains cable back to the unit.
- Ensure there is a minimum of 50mm between the heat power and data cable.
- Before connecting the drimaster eco to the phase connection unit, check that supply voltage is correct. Isolate at the mains before connecting the drimaster to the fuse connection unit. Then re-instate the power supply.
- Running costs dependent on electrical supplier and heating and speed setting.

Is there an equivalent type of unit that could be used to reduce mould and damp in a basement flat

QIs there an equivalent type of unit that could be used to reduce mould and damp in a basement flatanswer nowA
Hi I'm Phil from technical
Yes, the Nuaire Drimaster Eco Heat Positive Input Ventilation (PIV) Unit with an integral heater is designed for loft spaces, but there are equivalent units specifically designed for basement flats or properties without a loft.
For basement flats, Nuaire Flatmaster or Flatmaster 2000 models are excellent alternatives. These are designed for properties without lofts and can be installed on an external wall. The Flatmaster 2000 includes a heating element, similar to the Drimaster Eco Heat, which helps temper incoming air during colder months, making it more suitable for living spaces.
These units work by continuously introducing fresh, filtered air from outside, which pushes damp, stale air out of the property, helping to reduce condensation, dampness, and mould growth—key concerns in basement flats where ventilation can often be limited
many thanks kind regards phil
Do the eco-heat and eco-heat with switch versions come with the PM10 filters or are they only PM2.5? Is it only the eco-heat-NOX that comes with PM10? Thanks

QDo the eco-heat and eco-heat with switch versions come with the PM10 filters or are they only PM2.5? Is it only the eco-heat-NOX that comes with PM10? Thanksanswer nowA Good morning, The Drimaster filters are PM10 as are the white outer filters on the NOX Kit. The inner filters on the Nox Kit are PM2.5.Kind regards, Marc
Would your company offer the installation services? And will you have a site visit to the loft before I place the order?
-
QWould your company offer the installation services? And will you have a site visit to the loft before I place the order?answer nowA Good morning Jim. We only supply the products, we dont install them.You would need to make sure there is adequate ventilation up there and the roof vents havent been blocked off or the loft converted.Please refer to the installation instructions that you can find in the download section on our website, for guidance.Kind regards, Marc
How long is the standard duct length on these products. Can the duct be added to if I need a slightly longer run?

QHow long is the standard duct length on these products. Can the duct be added to if I need a slightly longer run?answer nowA Good morning Russell. The duct extends fully to 2m. Sadly, it cant be added to, as it will have an impact on the unit.Kind regards, Marc
Hi there,
I bought this a couple of weeks back and installed at the weekend. Its already making a difference - humidity has dropped within the house and the air just feels better! Really pleased so far.
Question though regarding the heater. Despite the temperatures being quite low the last few days, the air coming from the diffuser is cold. Ive tried altering the small blue dial on the diffuser panel, but doesnt seem to make any difference. There was a kind of heater element smell briefly - like the element was warming - but the air still feels cold, the element doesnt glow as I would expect so not sure if its working correctly.
Is there some way/setting where I can force the heater to kick in?
Thanks for your help.

Energy now being very expensive-how long should the Drimaster be switched on for? How much does it cost to run (say daily). Does it need to be on 24 hours to work efficiently? Thanks.
-
QEnergy now being very expensive-how long should the Drimaster be switched on for? How much does it cost to run (say daily). Does it need to be on 24 hours to work efficiently? Thanks.answer nowA Good morning Mark. The Drimaster will need to be running 24/7 365 days of the year. It works by pressurising the property through positive pressure. If you switch it off, it will a) stop performing and b) it could leave moisture inside the unit that could decay the electrics, which can lead to invalidating the warranty.The unit will consume about 11 watts per hour when in normally operating, but will use an extra 400watts when the heater is activated. That will only activate when the temperature is low in the loft. You can set the threshold to between 5 and 15 degrees, Kind regards, Marc
what is the db noise of the fan in the Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater By Nuaire
-
Qwhat is the db noise of the fan in the Drimaster Eco Heat Positive Input Ventilation Unit With Integral 400W Heater By Nuaireanswer nowA Good afternoon Jason, and apologies for not responding sooner.I have been searching everywhere for the noise ratings, but I probably should have gone straight to the manufacturer from the start. Anyway, assuming the fan speed is set at speed 4, the decibel level at 3m is 9dB and when it is on its boost speed, that rises to 19dB, which is actually pretty quiet.Kind regards, Marc.
How safe is this product with the heating element in terms of fire safety in the loft. Does it have a automatic cut-off safety aspect. I am worried about running a PIV with heating element when for instance you are away on holiday

QHow safe is this product with the heating element in terms of fire safety in the loft. Does it have a automatic cut-off safety aspect. I am worried about running a PIV with heating element when for instance you are away on holidayanswer nowA Good Morning JohnThank you for your question. The Drimaster heat unit has a thermal cut off and in the summer months the unit is on summer by pass so the heater is not on.

We would like to use your product in a rental property. The roof has a very low pitch which it is not possible to stand up in. Would this cause any problems with the operation of the unit.

QWe would like to use your product in a rental property. The roof has a very low pitch which it is not possible to stand up in. Would this cause any problems with the operation of the unit.answer nowA Good morning Alan. It depends on a few things really. Is the loft still ventilated? It should be. How low is the pitch and rough size property are we talking about?Generally speaking, if there is enough space to mount the unit in the loft, and plenty of fresh air getting in, then it is usually ok. A couple of photos of the loft may also help. You can email me directly on [email protected] regards, Marc.
Hi. Any idea what the heat recovery function it that the manual indicates please? Can you use the HC model without the 4 boost switch and add it later? An inline extractor fan (about 1.5m away) for the bathroom is in the room behind the hallway but that only comes on when the lights get switched on. Is this likely to stop the PIV flooding air to the rest of the house?

An inline extractor fan (about 1.5m away) for the bathroom is in the room behind the hallway but that only comes on when the lights get switched on. Is this likely to stop the PIV flooding air to the rest of the house?answer nowA Hello SpencerThe DRI-ECO-HEAT-HC fan unit includes an internal sensor toregulate the fan speed according to the temperature of the loft.The internal sensor will increase airflow to the dwelling when thetemperature in the loft is anywhere between 19-24 degrees celsius. Ifthe DRI-ECO-RH is purchased then the temperature sensor integralto this ancillary will be used to communicate with the PIV unit andshould the temperature in the loft become warmer than the dwelling, the fan will boost. The units Fixed Temperature Heat Recoverystrategies shall be achieved via these sensors and shall improveenergy performance accordingly. Yes you can add the 4 way switch at a later time, in regards to the in line fan this will not effect the unit.Kind RegardsAnita
Can this be mounted on a plaster/Lathe ceiling.
I have 250mm between joists is that sufficient to install

QCan this be mounted on a plaster/Lathe ceiling. I have 250mm between joists is that sufficient to installanswer nowA Hi Rob.The unit can either be suspended from the rafters utilising the cord that is supplied (this is the most common method) or can mounted to the beams using an AV mounting kit. You will need a couple of battens, which we dont supply. You will find this information on page 2 of the installation guide, which may help.Kind regards, Marc
Hi, our top floor bedroom covers the whole floor (no landing area). would this unit still be effective for the whole house?
-
QHi, our top floor bedroom covers the whole floor (no landing area). would this unit still be effective for the whole house?answer nowA Good morning Martin. The Drimaster will only be suitable if the loft space has not been converted and is still well ventilated. You may need to speak to someone at Nuaire Technical to find the best position to install if this is the case. If the top floor is the loft, then you would requite a Flatmaster, possibly 2, as they are only suitable for properties over 100m2.Kind regards, Marc
What is the difference between ECO-Heat-HC. model and the ECO-Heat-HCS model

Hi
I have one of the Drimaster eco heat models and the 4 way switch installed . Is the heater switched ON when the orange led is illuminated or does the orange led just mean that the heater circuit is enabled ready to kick ON & OFF according to where the blue thermostat control is positioned . I ask the question as I am conscious that the orange led being illuminated will be constantly running the heater element .

I ask the question as I am conscious that the orange led being illuminated will be constantly running the heater element . Regardsanswer nowA Good morning. The LED denotes that the heater is in Auto Mode, which basically means it will activate when the temperature drops below the temperature you have set, so therefore if the heater isnt on, then it wont be using any more power.Kind regards, Marc.

A The Heater is automatic, but you can adjust the threshold that the heat activates by. This ranges from 5 to 15 degrees Celcius.Kind regards, Marc
Is it acceptable to position the landing smoke detector on the bottom of the ceiling diffuser? I have heard this is an option on other units, but the installation instructions do not mention it?
-
QIs it acceptable to position the landing smoke detector on the bottom of the ceiling diffuser? I have heard this is an option on other units, but the installation instructions do not mention it?answer nowA Hello TobiThank you for your question. It is important to ensure that the diffuser is NOT placed within 1 metre of a smoke alarm. if thediffuser cannot be repositioned, two sides of the diffuser must be closed off using the air damssupplied to encourage the air through the remaining open sides that faces at least 1.5 metres ofunobstructed area away from the smoke alarm sensor.Kind RegardsAnita
How can this reduce humidity inside the home during wet days/months when the humidity outside is much higher than inside?
-
QHow can this reduce humidity inside the home during wet days/months when the humidity outside is much higher than inside?answer nowA Good afternoon Steve.The unit draws fresh air contained in the loft space and supplied it to the property. IT then pressurises the property and forces excess humidity out through natural leakage points such as airbricks, vent or key holes.If the loft is too hot in the summer, then the unit will go onto standby mode.I hope that helps.Kind regards, Marc.
If installed with loft/floor boards, judging by the photos the heating element would clash with the loft boards. Is it possible to extend the tubing between the diffuser and heating element to avoid cutting out more of the loft board than needed? I am also thinking about servicing needs in the future and just in case the element requires replacing it would be better to avoid lifting floor boards.

Will the unit definitely cure condensation forming on backs of drawer units etc. Rooms are already well ventilated. No drying of clothes indoors and no tumble dryer indoors. My contractor wants nearly £1000 to fit your unit and don’t want to spend that sort of money if it doesn’t definitely solve the problem.

My contractor wants nearly £1000 to fit your unit and don’t want to spend that sort of money if it doesn’t definitely solve the problem.answer nowA Good morning Trevor. I am hesitant to say definitely as there are factors that can hinder the Drimaster, such as, the loft not being ventilated, doors being closed with very little gap underneath. Providing the loft is well ventilated and is still drawing in plenty of fresh air, then the fan will gently bring fresh air into the property. For it to be effective, you will need either a 20mm gap at the bottom of interior doors, or each door to be slightly ajar, and dont butt up furniture such as wardrobes and chest of draws against the wall. try to leave a gap of about 3 inches to allow air to flow.You should notice a physical improvement within 24-48 hours.Kind regards, Marc

Can I ask you to obtain the serial number off of the unit, and give the sales team a call on 020 8463 9696 to discuss options.At this moment in time, Nuaire dont have any replacements units in stock, and they have had no phones and IT systems for 2 weeks, so they are little behind, so please bear with us, as it may take a little longer than usual to lodge the warranty enquiry with them.Kind regards, Marc
I have read previous questions and answers and see that you do not recommend the heated version in a house where the unit will be installed at the top of the stairwell as warm air will rise to the unit. My house has high ceilings and a loft, but Im not sure that it will be occupied all year round, so may sometimes be unheated. In that situation should I buy the heated version or not?
Many thanks

Many thanksanswer nowA Good morning Alison and thanks for your question.If Im honest, it may not make a great deal of difference to the temperature as the heater is only 400w. It is designed primarily to take the edge off the cold incoming air in the winter months. Unheated and empty properties are prone to rises of humidity, so either Drimaster model should help to keep humidity levels from rising too high.Kind regards, Marc

Hi, I have an old Dr, however, wimaster unit which is now making a loud click noise so I think something has come loose inside. So I am looking at replacing the unit. I have a couple of questions and hope you are able to answer these for me.
1) My current unit is on the floor in the loft on some batons to raise it up, can this unit be installed the same way or does it need to be hung from the rafters?
2) The current unit has heat but this is on constant and not something I have ever adjusted, with the new unit can I set it and not have to change it?

John Garton (verified owner) –
delivery and packaging second to none! not as yet had time to fit the unit, but it looks sturdy and well made, will post about performance later.
Pamela Newbury (verified owner) –
It does what it is intended to do.
Andy Patterson (verified owner) –
Great quality unit. Very quiet running & reducing humidity as expected.
Ashley Billman (verified owner) –
We have tried everything possible to clear up our condensation over the years. De humidifiers, window vents, larger extractor fans in kitchen and bathroom, soffit vents, roof vents you name it and we have tried it. Talking to our new neighbour who told me that he fitted one of these in his previous property and he never had condensation problems. Well we took his advice and bought one. The morning after fitting this we couldnt believe our eyes. All three bedroom windows, bathroom window, kitchen window and doors and conservatory were all condensation free, unbelievable. If you have any condensation problems fit one of these. You wont regret it.
John Godding (verified owner) –
I will be honest, I didnt expect this to work as well as some of the previous reviews, It arrived quickly and well packaged, came with good instructions, fitted and up and running within an hour. My house is a solid brick construction and has always suffered with heavy condensation to the windows. The unit is quiet up to speed setting 4 of 6. During the very cold days the unit will blow out cold air from the loft but its not too bad as its heated a bit to take the edge off. It took only two days for my house to be completely condensation free. An excellent buy Id recommend this to anyone suffering damp and condensation issues.
Alan Hurst (verified owner) –

I was in my sick bed recovering from a very bad chest infection,when I saw the DPD local delivery van pull up outside of my driveway. The driver was very careful in how he handled this bulky parcel,and very diligently carried it past my car. My Wife received it,but being disabled,asked the driver to put it in a place out of the way of the door. She came into my room after the driver left and said he was a real canny lad and was extra careful how he handled the package. Upon further recovery the next day,I ventured to have a look at the parcel,and heard the sound of broken eggshells from inside the box! Somehow,and it doesnt matter how,the backbox for the remote switch was shattered into lots of small pieces,and were rattling around causing further damage to the other parts,just minor,but damage nevertheless. I contacted i-sells.co.uk soon as I could,and immediately received a nice reply and apology from Kevin,at the company. All he required was the serial number of the machine,and that was that!! My finger had hardly pressed the send button on the e-mail,when I received a mail telling me a replacement unit was on its way,to be delivered today!! I only replied to Kevin yesterday morning after 11-0am,and the parcel arrived intact this afternoon!!! I forgot to state that the original order was processed and delivered within 2 days,with several update e-mails on the progress of the order! This is the second time I have dealt with this company and would recommend them to anyone!. It will be very hard to find another company so dedicated to customer care and after-sales service!! They have no fear of ever losing their reputation with this sort of service! Well done to i-sells,and Kevin,[and Cory,who dealt with me on a previous order!] NOW!,seeing as I am still recovering from being ill,I havent fitted the unit,but it is well made and designed,sturdy,the power supply is now built onto the machine very neatly,so no need for brackets to screw it onto a joist,as previously advertised. Everything about all the separate components,tells me that this machine will do its job fuss-free!! Once it is up and running,I will report in detail on its performance,in dealing with my condensation and mould problems in my bungalow. Up to now,five stars for a five-star company and team!! Bill.

Nice unit, easy to install. Unfortunately the string suspension supplied is not man enough. I replaced it with a gripple and 2 x eye hooks

Item was pretty much as expected, a couple of very minor niggles for me was that my lath and plaster ceilings were thicker than a typical plasterboard ceiling and so cutting a hole left no stable ceiling to screw this to, a small wooden ply support was made and it all now securely sits in the loft. The supplied 3amp fused spur socket is not great quality with a poor cable cord grip, both fairly minor points and not show stoppers. Performance is good, the fan is quite quiet and does as expected. Overall am pleased with the item. Service from i-Sells was very good and fast delivery, no complaints at all and will use again.

Having recently gone to all the extent to seal up all the drafts in the house we started to suffer with condensation on the windows. Got sick of going around in the mornings with the old Karcher so started to do a bit of research and came across the DRIMASTER ECO with HEAT. With all the positive reviews we bit the bullet and placed our order. 2 days later it arrived and I set about installing it. I found this easy to install with limited DIY skills and easily paired the system with the separate remote switch. The following morning VOILA, no more condensation problems. Not ran it with the heat as yet as wanting to keep the running costs as low as possible but I have no hesitation in recommending this unit. The whole process with i-sells from order to delivery was 1st Class.

The product worked as expected. However, it didnt come with a full installation / instruction manual. Which is not I-sells fault, but the manufacturer. I have still to receive a full instruction manual. Which would allow me to resolve an issue I had with the unit and to correctly configure it.

Best personal customer service I have received in a long time. Timely advice given and all promises fulfilled. Pricing query dealt with quickly and without fuss. Question about product answered within minutes of posting question. What more can I say, I shall be recommending this company to family and friends. Product ordered on a Thursday arrived following Monday. Product easy to install and after less than 20 hours in operation no overnight condensation on windows or door to outside. Damp room drying out as well. I wish I knew about this product years ago as I have tried so many other ways of clearing damp. Electrician who fitted it is already thinking of getting one after overnight results. Thanks to Anita and i-sells for all your help.

Good item recommend you get PIV heat version and 4 way switch, clears condensation and damp.
Mr Customer (verified owner) –
Highly recommended product. Have grappled with high humidity in my solid walled detached house for over 5 years. The results have been areas of mould, streaming windows, fabrics that are cold to touch etc. Despite making efforts to address this including improving the heating, adding trickle vents to windows, leaving windows open, improving extraction in bathrooms/kitchen and running a dehumidifier 24/7 could never fully resolve the issues. Within hours of fitting this PIV unit the air quality in the immediate area of the diffuser was noticeably improved. After a week of running, humidity levels have consistently dropped by around 10% (measured at multiple points around the house) and the environment is hugely improved in all the areas where I suffered previously. On reflection, shouldve just bought a PIV system years ago. If you have a situation like mine, dont procrastinate any further – buy!

Cleared really bad condensation in 2 days and has kept the house clear! Not too difficult to fit, did it in a couple of hours

Early days yet, only been fitted a week. No condensation first two days, but very cold next night and some condensation on windows (but also had wet washing indoors) so turned up air flow from 3 to 4. The house definitely feels drier and airier. Feels a little draughty on the landing and cooler than usual but not uncomfortably so. No noise from fan (and believe me my partner has ears like a bat, especially for sub-sonic hum so this was a major concern) we can only hear the sound of rushing air. Slight loft smell initially which has all but gone now. I installed this unit myself and was pretty simple to do; ran a spur off the lighting circuit to a twin socket, fitted a plug with a 5a fuse and suspended unit from a rafter on the supplied cord. No probs-an easy DIY if you are comfortable with electrics and dont mind working in the loft. Will be buying another unit for a rental property with bad mould and condensation problems. Also daughter wants one too, so will be fitting one for her. I have given 4 stars as I have not had the unit running long, and time (and Winter) will tell if it deserves 5 stars. I hope so.

Found this unit not as straight forward to fit as the instructions make out. If fitting the diffuser to a new plasterboard ceiling it should be straightforward but with an old lathe and plaster ceiling it was a fiddle. Could have done with some more material sticking through into attic to accept the heater unit. I used a straightened wire clothes hanger instead of nylon line supplied to suspend filter unit. Getting the flexible ducting to fit on this filter unit took two of us! Felt a bit like fitting a 26inch diameter tyre to a 27inch dia rim, the nylon ties are fairly substantial so are a bit stiff to tighten to keep ducting in place. Have tried it out, but set fan to 4 setting which seemed too much as blast of air coming through was cold, temp gauge registered 59deg with humidity at 61%. Before fitting humidity had been up to 80% with 62degrees although temp outside was warmer. We have an unfelted attic so plenty of air but this time of year (November) cold. Will try increasing temp and reduce flow. This might quieten the fan as well because at 4 setting I wouldnt say its silent.

The house suffered really bad from condensation on the windows and doors. Every morning having to get the karcher vac out was a real pain. After fitting this unit all I can say is WOW. The next morning just a few droplets at the bottom of the glass. The morning after that nothing at all. The house just feels so much better. Would recommend

It cleared condensation overnight. I have a 3 bed bungalow with no fans etc. Started at fan level 3 overnight with mid point heat and down to constant fan level 2 after one night. Hardly audible and so effective that I dont need any windows open now or even the trickle vents. Easy to fit as long as you realise that the ceiling template is within the packaging that I had thrown in the bin! As the hole is elliptical, I had to empty the bin! Even the cord and hook for hanging from purlins etc, is included. Fantastic product.

We installed this in our two bedroom semi and it has certainly cured the condensation. It takes a bit of adjusting initially to decide on an air flow that will suit your property in terms of temperature and so on but it does the job. Try and get it right during the day or youll be up and down ladders during the night to adjust! It certainly was worth purchasing after an extreme case of black mold in our home.
Carl Jephcote (verified owner) –
Brilliant. No condensation on windows anymore. I was sceptical it would work as I had been running a dehumidifier and emptying that on a daily basis and the windows still had condensation on them in the morning! Now I dont run the dehumidifier and have reduced the air flow setting from 3 to 2 in my 3 bed house. Humidity now at 49 – 52% Couple of minor draw backs. I have the heated version the incoming tempered air is still quite cold. Which lowers the temp in the hallway. Second is the price. £340 is a lot for a large fan and some basic electronics.
David Turner (verified owner) –
live in a 2 bed bungalow the windows were constantly wet with condensation and mold was starting to develop around window and door, fed up with having to put the window on vent in cold weather to try and clear it, so decided to splash out and get the drimaster eco vent, noticed a vast improvement immediately, I was restricted on a suitable location due to the small hall, this has reduced the effect of the unit but on the number 4 speed setting the kitchen and living room are generally free of condensation, still a small amount on the bedroom windows but this is due to the limited option of a suitable fitting location. Worth the cost as without it the mold would have gotten out of hand.

I live in a 1920s three bed semi. I dont have damp walls but in the winter the windows were so heavy with condensation that I used a vax thing to hoover all the water off and getting a couple of tanks full. My humidity was in the house was generally over 70%. I therefore decided to try this gadget (I like gadgets). It was reasonably easy to fit despite some lathe and wattle ceilings and it looks quite unobtrusive in the hall. The first thing I noticed was that on high it really does cool the stair well and it is very noticeable noisy. However it did reduce the humidity into the low sixties. As time has gone on I have reduced the setting to 2 and it is no longer noticeable at all. The humidity has gradually come further down over the months and I am now routinely under 50%. I also only get condensation on the windows after very cold night. However, it is only about an inch at the bottom which clears itself quite quickly as the day warms up. Ive had now had this for about six months and I really do think its made a massive difference although you need to give it time. Definitely recommend.

This was delivered next working day…I fitted the system myself and within 2 weeks has cured our condensation problems.. Damp areas on walls and windows have gone, internal doors fit better again, laminate flooring had become mousey when you walked on it, now back to normal. Also air quality is much better, stale food smells do not linger..We have an open plan living area so this is really helpful….In fact It is only when you have removed the issues that you realise how good this system is…Great value for money too…I highly recommend this….

I’m really impressed with the NuAire Dri Eco Heat. Over the winter the windows were always had condensation on them and since having a new front door the house was sealed up which was leading to some mould forming around the door and windows. Once the unit was fitted I saw an improvement within the first day. I set the unit to 3 and the next day I turned it down to 2 which is sufficient for my 2 bed bungalow. I did fit one on the plastic diverters as my central heating thermostat was quite close and I felt the cooler air was blowing onto it. Once the diverter was fitted though this solved the problem. The unit went into standby one day but this was because the loft had reached a higher temperature, the unit kicked in that night though. I’m impresssed how the unit has got rid of almost all condensation on the windows and how it keeps the house fresh. It does make the hallway slightly cooler even with the heat, I don’t mind this though as the benefits outweigh this. I added the controller switch which allows you to boost the unit bringing more fresh air into the house. It’s a considered purchase, but if you have condensation problems I would seriously consider this, I wish I had got it years ago. The unit is almost silent on speed 2, I can’t hear it on a night. The service from I-sells was superb, the unit arrived within a couple of days with a follow up email. Overall 5 stars !

Having had the OLD green Drimaster Heat in use in my house for 5 years and being very impressed with how such a simple fan setup can keep the house fresh and dry I was getting frustrated with having to get the loft ladders out to access the loft to change the fan speed etc. Once in the loft this would involve the awkward task of navigating the loft insulation and beams to get to the fan unit where the controls for the fan were. In the warmer months and spring I have the fan speed set on speed 6 which is the maximum setting as a like the house to be well aired and fresh. YouTube overview: The concept: The fan is mounted at a central point in the house, usually the hall or landing. This fan pulls air from the loft that is generally a few degrees warmer than outside even in winter months and this fresh air is used to ventilate the house. You can keep your windows closed as the house is not air tight so think of your house like a balloon with small holes in it, the fan blows air into the balloon blowing it up slightly but this balloon has holes in it which represent the gaps in the house structure so gaps in windows, floor boards & under doors. Fresh air is pumped in and slightly pressurises the house (like blowing a balloon up slightly) and mixes and dilutes with the moist air (from drying washing, cooking, cleaning, bathrooms and breathing) already in the house. This then escapes through the aforementioned gaps keeping the house fresh and dry in the process. The result is that mould and damp are simply removed from the house, even odours from cooking/bathrooms or those bedroom smells you get on a morning do not build up if internal doors are left ajar as the air is constantly replaced. Even windows don’t steam up or if they do they clear very quickly come the morning. A house with dry air in is cheaper to heat than a house with damp musty stale air in so energy bills come down. In the winter I set it down to speed 3 as the air coming into the house naturally has a lower moisture content due to being colder. I then saw that the newly designed Drimaster ECO heat was now available to buy which has generally modernised the controls and look. Separately is an option to buy a neat modern looking remote switch which allows you to control the Drimaster from your landing. iSells: Firstly the service from iSells has been fantastic, I have used them before to purchase a bathroom extractor fan and the good customer service back then was reciprocated once again now. I highly recommend them for your ventilation needs as they also offer great advice if you are involved in any ventilation projects at home or commercially. They communicated well with me and I was told along the way when the item was dispatched etc. so I could prepare for delivery and make sure I was in. Once the package had arrived I noted it was very well packaged into a neat box. Installation: if this is your first unit you will require an electrician to do the electrical work however if your competent at DIY then you could mount the fan in the loft and cut the hole in your ceiling plasterboard for the diffuser to fit. This requires a 200mm hole however I made this a couple of mm over so the diffuser would fit in easily. Comparison of the previous diffuser is that this is now round and the old one was a square diffuser. This meant cutting an addition small corner into the existing hole as this incorporates the control PCB. I feel that this could have been built into the diffuser better so that if you was upgrading from the older style Drimaster this would be a straight swap. However once the hole was cut, fitting the diffuser was easy enough, although once again the screw holes from the old diffuser could have been utilised, instead I had to drill new ones, again adding extra time to the swap over. However, the new diffuser looks neater and is thinner it sits closer to the ceiling than the previous square one improving air circulation. I have chosen to use the cord to suspend the fan unit from the rafters in my loft, the closer it is to the roof tiles the better as warmer air rises in the loft so it is likely to benefit from pulling this warmer air layer into the house. You literally put a hook or a screw into the rafter, adjust the length of the cord and then hook the fan unit onto the metal hook on the end of the cord. The fan then just hangs in mid-air; this is the choice of installation for me as this stops any transmission of vibrations into the house if you chose to mount it on the landing ceiling joists. Once the diffuser is in place, the heater unit connects to this, and then this is connected to the diffuser control PCB via the Molex plug. The heater unit clips into place very easily on the top loft side of the diffuser. You then connect the ducting to link the two between the fan unit… see pictures. The heater unit and fan unit are also connected via two connectors one being the power lead and the other being another Molex connector which controls the fan unit. I must say this is a more complicated setup than previous – this has to be the case though due to the controls being mounted on the underside of the diffuser for convenience. This is as far as I can go with the installation now; your electrician then is left to connect the mains power lead to the power point in the loft. This is by means of a fused switch spur on the landing that in my circumstances connects to a plug socket in the loft. As I already had a Drimaster it just involved swapping the mains 3 pin plug from the old Drimaster to the new Drimaster ECO. Previously the heater unit was a separate unit that was controlled independently from the fan and had its own power supply so you could put this on a timer plug to say only run the heater on a morning etc. This is no longer the case if you run it on a timer plug the whole thing fan and all will turn off and the Drimaster fan must run all the time otherwise warmer humid air will rise up the ducting and condense on the cold fan motor and possibly damage the unit. If the fan is off then the house is not being ventilated so you don’t want to turn it off anyway. All that’s left to do is commission and get it up and running.

I was apprehensive at first and a bit worried about the potential noise that this unit would make. I had recently moved from the city to a very rural country cottage so spoiling the new found silence was a definite concern. Im very average with DIY but managed to cut the required hole into a plasterboard ceiling relatively easily. I was fortunate enough to have an electrical socket already in the loft so I just wired a plug on to the supply cable and that was me connected. Due to the only place I could fit the unit, It was located just round the corner from and a small distance away (1.5 meters) from the nearest bedroom door. Due to this I have been able to set mine on full blast (No 6) and I am unable to hear the fan running from my bedroom. Immediately i noticed the back of my aluminium letterbox flap was no longer covered in condensation and that the quality of air in my property seemed much fresher. The cooking smells no longer get into the living room even if the adjoining door is open and the cooking smells dont linger like they used to do in the kitchen. Even with all the internal doors open the only place i can feel a temperature difference is near the defuser in the hallway. My central heating is run of a coal/logs burning stove and the heat can be ridiculous, so walking up the stairs and in the cooler hallway can sometimes be quite refreshing. Within a week of fitting we had a really cold snap that caused the heater to kick in which tempered the lower air temperature in the hallway which seemed to work well and make sense. I initially bought this unit due to the homebuyers report stating about condensation and slight dampness which was causing small amounts of black mould and while its early days, i have full confidence in this item. Just before writing the review I slightly cracked the kitchen window open and held a thin piece of tissue paper (bog roll) next to the gap and lo and behold the tissue paper was being pulled towards the gap which reinforces the fact that the air is being pushed out of the property. Im totally convinced and would definitely have one fitted in any future property that I might purchase.
