We are considering using monobloc A2A heat pumps to provide most of the heating of our house, and any advice, experiences, opinions etc. would be most welcome.
The plan is use 3 heat pumps: one at each end of a fairly open plan area comprising the lounge, dining area, kitchen, hall and stairs, and the third in the other main ground floor room. Heating of the bedrooms and other rooms is to be tackled later.
The possible heat pumps that I've found are:
They are all similar: heat output in the range 2-2.5kW, R290 (propane) refrigerant, can cool as well as heat, inverter compressor. Not surprisingly, given the price, my favourite is currently the electriQ. I know that @bombinho has a Powrmatic Vision Compact (did you ever solve your vibration problem?), and that @alun has an Olimpia Splendid Unico (rejected because of R410A refrigerant), but other suggestions are welcome.
Our main concern is noise: we live in a quiet location and even low levels of noise might be disturbing. I'm hoping that we can keep the fan on its lowest setting and rely on convection currents and radiation to distribute the heat.
I'd be particularly interested if anyone has experience of Trotec A2A heat pumps (under any of their badges).
