Size Name:6 Rooms 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! The system parts are as follows: 1 Room System Parts 2 x Air Valves 2 x Wall Grilles 1 x 10m Ducting 8 x Ties 2 Room System Parts 2 x Air Valves 2 x Wall Grilles 2 x 10m Ducting 8 x Ties 3 Room System Parts 3 x Air Valves 2 x Wall Grilles 1 x Tee 3 x 10m Ducting 12 x Ties 4 Room System Parts 4 x Air Valves 2 x Wall Grilles 2 x Tees 4 x 10m Ducting 16 x Ties 5 Room System Parts 5 x Air Valves 2 x Wall Grilles 3 x Tees 5 x 10m Ducting 20 x Ties 6 Room System Parts 6 x Air Valves 2 x Wall Grilles 4 x Tees6 x 10m Ducting 24 x TiesEach unit comes with a 2 speed controller as standard.
