Aluminium Heat ExchangerHigh performance aluminium heat exchanger, transfers heat to the incoming air supply with an efficiency of up to 90%. Ideal for those who require the highest level of energy saving. These units come with a built in condensate tray that needs to be connected to a drain. Enthalpic Heat ExchangerHigh quality enthalpic heat exchanger transfers heat to the incoming air supply without creation of excessive condensation. As such these units do not need to be connected to a condensation drain making them ideal for an easy, straightforward installation. |

HRVU Guide
Heat Recovery Ventilation (also known as HRV, or mechanical MHVR) is an energy recovery system whereby a household or room is provided with fresh air from outside. Stale air from inside is exhausted after the heat from it has been transferred to the fresh incoming air via a heat exchanger.
As buildings are made efficient they are intentionally made more air tight, and consequently they are less well ventilated. Trickle vents or simply opening a window provide fresh air, but unfortunately heat will be lost in the winter and gained in the summer. HRV systems provide a household with climate control and promote energy efficiency!
