Any input on my dilemma is much appreciated as I find myself going around in circles in regard to which set up to choose from:
1) Air to water heat-pump circa 8 kw diakin split unit with a 260 liter water tank included for DHW and the UFH. To complement this there will be a 10 kw dry cassette stove in the living room which has extra extract hrv ducts in place which will be set to open when temp in room rises.
2) A EG -pellet 10 KW boiler or defro 10 KW which will feed into a 500 liter buffer tank with a stainless steel DHW coil and the UFH fed off the tank through a mixing valve. to complement this there will be a 14 Kw boiler cassette stove which will fed the same tank 10 kw of power.
The house is built to passive standard thus load will be quite low. Both systems offer economical running but I kind of like the idea of having a redundancy with a boiler stove if you under stand me.
Once again any comments very much appreciated.
