I believe they are trying out things called heat pumps but I'm not sure how much of a success that is... If anything...

I still am a firm believer of solar on each house, a 3kW system wouldn't take much space up and everyone would have 'free' power... Cause isn't that what they want us to do, renewable energy etc.? Or would that mean the big firms would loose money..... ummm.... Such a tuffie....
They are, but whilst in the future they will no doubt become cheaper, currently they are around 3 times more expensive than the boiler equivalent with installation and in a cost of living crisis not just caused by energy prices uptake during the next 3 years or so would I guess be limited................. apparently, the average saving when compared to a modern boiler would be around 15% so the challenge would remain that people buying these at current prices would not be intending to move home for at least 10 years.

Heat pumps are very common in north America and parts of the Orient.

They are comparable in price to a Split air conditioner with a gas furnace - not a heating only system.

When your daily summer temperatures are >35C for 4 months straight, you need air conditioning.

A new boiler system (complete) is probably comparable to a heat pump, at least on a larger house. However, retrofitting is much harder.

Heat pumps are around 260% efficiency as a rule of thumb. Boilers are mostly 95% if you get a nice one. Below are some calculations:

34p (electric price) divided by 2.6 (COP of heat pump) means that for heating your house by 1 Kw will cost 13.4p for electric.

10.3p (gas price) divided by .95 (boiler efficiency) means that for heating your house by 1 Kw will cost 10.8p for gas.

The advantage is having A/C so you can weather the hot months (at the cost of more electric) if you want.

In the UK, you use hot water radiators? That will come with a pump energy penalty, but comparable to the fan on a heat pump or furnace.

The thing is, many appliances that use heating use straight resistance heat - which costs 34p to heat by 1 Kw - for example a stove, oven, clothes dryer, erc. Changing these our for gas versions will reduce energy use by 70%.

I'm not sure about the heat pumps yet as they are massively expensive over here still which I think @Tatty_One has mentioned already but we seem to be getting hotter summers and such, so gas boilers not really ideal for cooling things down as such so... lol

I look forward to seeing some real differences in how we get our electric, heating, hot water and such like.. It would be good to have a good shake up :)

I mean this is my Threadripper system trying to do a bit of folding and crunching together... Wonder if that will warm up the house cheaper than using gas....... :D :D

Power definitely not cheap here.. With the solar panels its OK but its the UK, mostly more cloud than just good sun sadly... I've had most of the rigs I can on working today but you'd possibly be surprised that when your folding as well with the GPUs, 3000w of solar power, doesn't go quite as far as you think it will... I'll try and get a list up at some point :)
