The heatpumps for heating water are crazy expensive at the moment. It makes no sense as they are a lot cheaper in Norway. However an air system with a few zones driven by a heatpump (air to air or ground to air) less than a third of the price installed and will also provide cooling in the summer with the same efficiency and replace all the radiators.
I think we are just being ripped off at the moment for replacements for radiators when air to air works just fine and takes up less house space anyway. Its worth looking into because the 20k heat pumps into water are not paying back in 25 years whereas you can maybe get an air to air to be neutral cost over its expected life time compared to a boiler replacement.
Yeah, it’s the water heating that’s putting me off. A combi boiler is just so much better for it.
We should be pushing hybrid solutions where the house is heated by heat pumps (which as far as I can tell is just reverse air conditioning), and keep the boiler for hot water.
I’m certainly not going back to a crappy hot water tank, and being unable to have a bath because I did the washing up earlier.
We can’t keep burning gas there won’t be any in a decades time. We don’t have any choice about storage of hot water or heating electrically and using water to store excess energy makes a lot of sense. However take a look at Sunamp they do a phase change material tank like thing which takes less space so you can get the sort of capacity you want.

There is no shortage of gas, we won’t run out in a decade. We need to stop using the stuff as much as possible as soon as possible though.
