alt Hacker NewsIt's high but it really depends on your lifestyle and appliances.
If you have a heat pump water heater and heat pump based floor heating you'll use 1/4th of the energy as the same house with resistive water/floor heating.
A house which barely passed regulation from 2010 will consume 5-10x the energy of a certified passive house.
etc.
That being said I think you have to draw the line somewhere. I'd much rather have inefficient appliances (resistive boiler/heaters) and be fully solar powered than spend 50k in heatpumps and other gimmicks that are rated for 10 years and cost a kidney in maintenance and the eventual replacement.

Anecdotally, two of the smartest people I know love heat pumps—doesn’t Technology Connections too?
Was probably this:
Heat Pumps: the Future of Home HeatingHeat pumps aren't particularly expensive though and they can provide cooling.
Who spends $50K on heat pumps? They're not anywhere near that expensive.
Heatpumps can now be had for less than £10k .. if you don't have to replace your radiators.
I do think more people should consider mini-split reversible AC in the UK, but the subsidy system specifically excludes it.
Heatpumps are not a gimmick - they're an excellent technology with lots of efficient and effective uses :)
