Heat pumps are saving Europe billions by lowering gas imports

a day ago by ZkhqrD5o to c/europe

A new analysis says that heat pumps avoided a staggering €9.7 billion in import costs alone last year.

Fuck fossil fuels.

I get that, but in the UK they're so expensive for homeowners. The uptake isn't quick enough.

Out of interest, just how expensive are they? I can get a minisplit heat pump installed on our house for about a 1000€ (higher end models are obviously more expensive) here in Finland. It requires a small-ish hole trough the wall for pipes/wires, but otherwise the installation is pretty easy.

We have one in the house and another in garage and both have already paid for themselves since I don't need to run electric radiators anymore. Newer models would be even more efficient, but as the current ones still work they're not the first thing on the long list of house maintenance.

What are we talking about here? The machine itself + installation? How many square meters are we talking about? I've checked recently and two splits for 30m^2 each (so 60m^2 total) would cost me about 1.5k and that's with the top, most efficient model.

Single unit for only 30m² sounds a bit excessive. At the house we have one split unit and it has ~170m² in two floors. On top of that we have electric heating in the wet spaces (shower, sauna, laundry room) and couple of radiators in the bedrooms (which are rarely used). Those alone would are just fine most of the year, but we also have a pretty big wood oven and a wood stove and while we could use only the heat pump+radiators it's a lot cheaper to use wood during winter. Also warmth from the oven feels better, but only for heat it's not strictly necessary until temperature drops below -25C.

In Spain people tend to install separate units for each room instead of one big unit for the whole apartment. Central units that let you control each room separately are quite expensive. It's cheaper to install few small units and just turn on the ones you need: usually the one in salon during the day and the one in bedroom for the night. But that's for AC because you can just let empty rooms to sit at 30 degree without issues. With heating it's different, you can't just let parts of your house to freeze. In southern Spain we don't have freezing temperatures and I don't know what people in other parts of Spain do for heating.

Actually you shouldn't (if you can avoid it and I understand it's expensive) let room just sit in 30C heat if you plan on air conditioning them later. When you are cooling a room, it's just the air: the furniture, walls, everything has become a heat sink in 30 degree weather.

So you are better off keeping the room somewhat cool before you use it and go full cool.
