Finally we managed to employ the Altherma Air to Water heating pump. It's nothing short of amazing.It is operative for 4 days now and the house is heated @ 19 degrees C. This is with 2 of the 6 floor heating loops not functioning properly because of trapped air and mains feed Voltage of 160 - 170 Volt (thanks EVN a**holes) . That's why we installed a 6 KW voltage corrector for the heat pump, the backup electric heaters are operating although on the mains feed Voltage of 160 - 170 Volt uncorrected.
Anyhow, we can already say that we will have a warm home spending little
energy when all systems are nominal, house insulation pays always.
