>>18122382>But why two different categories/words for the same appliance?if they cheap out, sometimes they cannot do both, heating and cooling
i think the differentiation is only for the size and mobility of the heat pump
and the rest seems to be marketing
>>18122382>What goes in there?just tubes
you send cold (or warm) water down the hole and it comes up warmer (or colder) - then you utilize the heat difference
if you dig 75-100m deep, it's 12-15°C year round
pic rel is how the systems generally look
>We already got radiators for heat in the winterif you live in apartment you don't have much influence over the heating method anyway
you probably heat with gas
and heat pumps are only directly worth it if gas is like 3-4x the price of electricity
>could use the split a/c for heating but it is less efficient.for normal ACs yeah
i get a JAZ of ~4, so for every kWh the heat pump consumes I get 4.5kWh of heat out of it
