@paulrudman I'm not gonna deny that gas is still cheaper, but just keep in mind it would only cost that much with 30 straight days of not-breaking 0°F/-18°C.
With our rates, that day cost about $30. But the rest of the month averaged closer to $10/day. It was still a frightful power bill for them, and they absolutely should have a heat pump. (edit - did the math wrong)
@TechConnectify @paulrudman This is on point. 10 kW is the maximum. And that's for a large and inefficient American home in cold American winters. The average UK home only has a peak heat loss of between 6-8 kW. So...on the coldest hour of the coldest day of the year the average home still use less than 10kW.
And that's before you consider a heat pump which will use only on average a 1/3 the energy.
