I plan to use air2water heat pump for heating, but the problem is high price of these heat pumps.
Can I use external part of air2air heat pump (Fujitsu AWY14LAZ, for exampe) and connect to it refrigerant2water plate heat exchanger (Alfa Laval AC30, for example).
Is it possible?
I can use controller of the internal part of the air2air pump, the thermistor have to be recalculated.
Does anybody know, what are the normal coolant input and output temperatures for air2air hvac, when heating?
