#ClimateDiary We are in intense #Heatpump vs new boiler discussions in our household at the moment, and it is quite something how geopolitics and radiators (and other practicalities like: will the humming be loud?) all swirl through my head at once.
(Our house is old, terraced and high ceilings - it looks like it’s not impossible but challenging. Costs come into it too, of course. Also worried on this front: might geopolitics mean i will not earn any money next few years?)
@pvonhellermannn I got one last August. It works well and it's quiet. Needs more room than boiler, and because electricity cost is excessive (due to gas setting the price point) heating bills have stayed about the same.
If you already have solar panels this will help the economics of it substantially, even more so if you have solar + battery. I do not, that's next on my list
@http_error_418 @pvonhellermannn we're doing quite well on the Octopus Cosy Tariff
It's a bit hard to work out costs - I made a start on number crunching but so far I just have a bunch of daily figures based on how much power was used at what time of day and how efficient the heat pump was running.
Today I have had heat at 4.4p per Kwh
gas at 6p per kwH * 85% efficiency would be 7p
During colder times the heat pump has been less efficient but I think overall it's been cheaper.
