Anyone have one of these or thinking about getting one? With the Boiler Upgrade Scheme this could be a good time but I’m interested to know other’s experiences.
Preferably mechanical ventilation with heat recovery installed first, as no air can enter from draughts any more.
.
A very general point on this though - if you don't have/ are not planning (maybe don't have space for!) MVHR - don't worry about the small incidental 'calibrated leaks' left.Ours isn't completely sealed to Passivhaus standards by any means (although the majority of the ventilation previously was from how badly the windows were installed).
I am always puzzled by this notion i read here that heat pumps only work on a very well insulated house. Surely, a HP kW does the same job as a gas boiler kW. It is obvious that a house with abundant air leaks requires more kWs to maintain a given temperature. But I don't see what the heat source has to do with it.
