UK retail electricity has suddenly risen from about 12p a kw to 18p. So even if you achieve a real world COP ratio of 3x you will be paying twice the price of mains gas and a little more than oil. Ironically this is partly due to a levy to fund green subsidies that seems to apply to electricity but not gas? I'm not sure people have factored this in yet, if electricity does not come down in price it rather ruins heat pump economics. The other mystery is why we still buy night storage heaters not mini split air conditioners? Do they not work?
