Fresh air or energy savings? With our heat recovery ventilation appliances you can have both. Regardless of the age or size of your home, we have the right system for you.

With up to 80% of allergy triggers being avoided with special pollen filters, our heat recovery ventilation (HRV) systems can deliver the air changes required for healthy air and optimum energy efficiency. Alongside insulation and any formal heating technology, you may need, our Genvex, Zehnder and Vent-Axia ventilation appliances are one of the necessary components in the energy-saving homes of today.

heat recovery ventilation appliances

Nothing can deliver fresh filtered air and remove moisture together with pollutants like a whole house ventilation system. When combined with a heat exchanger, significant energy savings help towards the Code for Sustainable Homes.

The ECO 375 is a heat recovery ventilation appliance with an extremely efficient counterflow heat exchanger at a heat recovery rate of 96%. It has low watt EC motors (electronically commutated) for minimal electrical consumption. What's more, it is equipped with a fully modulating summer bypass as standard, so heat won't be recovered on those hot-summer nights!

The entire ECO 375 stands out by being particularly energy-optimised and adapted to the percise requirements of the BR18 low-energy class.

The range includes:


179 / 1,927
