"The average home uses 12,000 kWh for heating per year, according to the latest Ofgem data.
Fortunately, the typical air source heat pump produces three units of heat energy for every unit of electricity it uses, largely because water holds onto more heat than air.
Where your pump falls on this scale is called its Coefficient of Performance. With three units of heat produced for every unit of energy, its efficiency rate will be 300%.
If your pump is your sole heating system, that means you’ll only need to use 4,000kWh of electricity to produce the 12,000kWh of heat needed to heat the average home over a year.
However electricity’s average price is currently 34p per kWh according to Ofgem, while gas only costs a relatively low 10.3p per kWh. That’s 3.3 times higher.
So one factor reduces your costs by 300%, while the other increases your costs by 330%, meaning you'll pay slightly more in energy bills.
Instead of paying £1,236 per year with a typical gas boiler, you’ll pay £1,360 with an air source heat pump – but that's not the end of the story."

Oh dear, the running costs are actually higher but they tell me that gas will become more expensive in the future whilst air is likely to remain FREE. Do I accept their confidence in forecasting the future? Can any contributor here direct me to the supplier of renewable energy that is 9X cheaper? I'll make it easy - I'll settle for half price.
