How Does a Heat Recovery Unit Work?

There are various types of heat recovery units we offer at I-Sells, what works for you is entirely dependent on the size of your home and your needs. Let us share some examples.

This heat recovery unit is useable for medium-sized houses and apartments:

The unit is 100% completely safe for you to put in your bedroom or your child’s bedroom since it has a very low voltage. By providing adequate ventilation the unit maintains the recommended humidity levels, preventing harmful bacteria from being breathed in.

We understand that appliances can be investments that can put you out of pocket, but we at I-Sells have every base covered. Here is an example of one of our affordable units that will help you save money on your bills and on your bank account.

Vent Axia Lo-Carbon Tempra P Heat Recovery Unit (443312)

The Vent Axia Lo-Carbon Tempra P Heat Recovery Unit (443312) is available with pullcord control, timer control or humidistat, timer and pullcord. All models are also available in SELV (Safety Extra Low Voltage).

Low energy consumption means the Tempra exceeds the energy-saving requirements in Part L, Conservation of Fuel and Power. With several optimisation options available to adjust the fan speed.

The units are fitted with a 24V ECDC motor with a state-of-the-art built-in power supply. This has the ability to operate at only 2 Watts power consumption on normal setting, offering a 90% energy saving over conventional AC equivalents

Apart from removing odours, providing fresh air and recovering heat, this appliance extracts airborne impurities such as dust, dirt and grease. These gradually build up and detract from the efficiency and appearance of the appliance. To ensure peak performance, the heat exchanger should be cleaned as required in accordance with the instructions supplied.

Is it worth the investment?

We feel like we have answered the question ‘how does a heat recovery unit work’ so now let us briefly summarise why they are worth the investment.

As energy bills increase along with the growing sentiment from the government to be energy efficient, a heat recovery unit is definitely worth investing in to make the most out of your heat rather than unintentionally wasting it and potentially adding more to your energy bills.

Not only are you making a conscious decision to help the environment, but you are also keeping your home and its inhabitants warm and refreshed.

The extra benefit of helping to create a mould and condensation-free environment in your home is also invaluable, especially for those with mould allergies or existing health conditions.

The versatility and amount of options available when it comes to heat recovery units means that regardless of what room it gets put in, you instantly get to reap the benefits.
