Heat Recovery Ventilation

Auto Bypass and Pre-heat Functionality

This unit comes with both the pre-heat and auto bypass functionalities. The auto bypass function allows the unit to bypass the heat exchanger, meaning the heat energy isn’t transferred to the incoming air. The pre-heat function warms the cool air taken in from outside in addition to the heat exchanged from the internal air.

Heat Exchanger

Aluminium High Performance Heat Exchanger

High quality aluminium heat exchanger, transfers heat to the incoming air supply with an efficiency of 90%. This may however create some condensation due to the temperature difference between the incoming and out going air. As such these units come with a built in condensate tray that needs to be connected to a condensation drain

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!

This is an example of an installation with one inlet or outlet per room. With this set up, you would extract from your wet rooms (kitchen, bathrooms)& push into your dry rooms (Living rooms, bedrooms). This is an example of an installation with two inlets / outlets per room. With this set up, you would extract and push into each room. Normally the fresh air vent would be placed as far away from the door as possible.
