If we just insulated to passive house standards an average 100m2 British house would need about 1500kwh a year to heat it. With a modern air-water heat pump that’ll be less than 500kwh of electric burned. <£200 a year at today’s mega high prices.
That's completely unfeasible for the UK, there is a reason why it lags behind so many other countries. You can't just have an army of cowboys build shoddy passive houses, they need to be done properly and then also operated properly to work long term.
Heatpumps are similar, they need to be planned and build properly or they just burn through electricity. In Germany they are having second thoughts about them because they don't have enough qualified staff to install them and people end up heatpumps that just heat with electricity and generate massive bills and that's with proper regulated trades.
Some were also suggesting the owners need to be trained to operate them correctly or they will not work efficiently.

Yep, but it’s definitely feasible. It’s hard, sure, but it’s all technology that’s understood and proven and that makes it way easier to implement than trial-and-erroring the inevitable hare-brained gimmicks that we’re about to be flooded with.
That was my point really. We don’t need anything new, we just need to properly implement current tech.
If only we hadn’t stopped all the Eastern European engineers coming over.
Hefty
Meh. Tech wazzocks inventing yet more stupid gimmicky solutions when we already know exactly what to do and could do it now.
