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.
