NUAIRE MRXBOX-ECO HIGH DUTY WALL MOUNTED HEAT RECOVERY VENTILATION UNIT
The MRXBOX range of heat recovery systems provides the most effective, balanced supply and mechanical extract ventilation with heat recovery, with an automatic summer bypass as standard. The MRXBOX is a high performance, a powerful unit which has an extremely low Specific Fan Power (SFP) and uses ultra-modern low voltage DC fans but is still powerful enough to provide excellent ventilation for medium to large properties with up to seven wet rooms.
In common with the rest of the MVHR Range, this unit recovers up to 95% of heat which would otherwise be wasted, whilst also reducing power consumption, meaning it will help you achieve a high SAP score. The unit is an ultra-quiet unit with a long life motor, which makes for low running and operating costs, straightforward maintenance and years of trouble-free operation. Also available in an opposite-handed format
High performance, wall-mounted MVHR unit which is specifically designed for medium to large houses and apartments. With low energy usage and with up to 95% of heat recovered, this system is a whole-home system to ventilate up to seven wet rooms and will help you achieve a high SAP score.

Questions and answers of the customers

As the MVHR system runs continuously, are Building Standard extract rate requirements lower than for a normal extract fan?
-
QAs the MVHR system runs continuously, are Building Standard extract rate requirements lower than for a normal extract fan?answer nowA Good morning. Building regs will require an extract rate from a standard bathroom of a minimum of 15l/s. That is the minimum you must be able to achieve, whether you have an extract fan, or MVHR. Trickle speeds will be slightly less if on a constant. It is important to make sure the MVHR that you are looking to purchase has the correct flow rate for the size of property. We would need drawings with dimensions to be able to suggest a suitable unit.Kind regards, Marc

To whom it may concern at Nuaire,
Could I please confirm the correct location of the inlets associated with this MVHR unit? Would they need to be located away from the roadside or at greater heights?
We are currently looking at a development which requires NO2 reduction at ground and first floor levels - so in addition to this unit I have suggested the IAQBOX-S - these are fairly small flats (2-3 wet rooms) - would this MVHR in conjuction with this carbon filtration system be compatible/suggested on your end?
I would appreciate any advise in this matter,
Best,
Ed C

Hi, Does this unit need a minimum amount of space left around the unit to fit ducting and for access?
-
QHi, Does this unit need a minimum amount of space left around the unit to fit ducting and for access?answer nowA Hi RebeccaThe unit has 150mm spigots, two of these go out to atmosphere and one of the other two branches off to (presumably) several rooms in the dwelling, extracting bathrooms, kitchen WC and utility rooms.The fourth ducts and branches to the bedrooms, lounge dining room etc.Because of this the unit and ducting require space to reach all of the rooms but more importantly, the installer requires space to work!
