HEAT PUMPS ARE NOT THE SOLUTION
Combination and condensing gas boilers are efficient, relatively quiet, cheap to run, relatively cheap to replace, and work well in summer and winter.
They can be mounted in a hallway or a kitchen or even in a downstairs toilet. The gas fuel is 1/4 of the price of electricity. They use just 50W of electricity to run.
An Air Source Heat Pump (ASHP) suitable for a three-bedroomed house is enormous compared with a gas boiler. It is only 75% efficient and costs an eye watering £12,000-£25,000 to purchase and install.
Despite claims to the contrary the ASHP doesn’t work well in the winter when needed most. These cannot be fitted in the house but are free standing outside. Smaller units can be wall mounted. A 19kW unit consumes 6.3kW of electricity to run the fan.
The cost of electricity to run the ASHP is greater than the cost of the gas used to power a gas boiler.
One ASHP consumes enough electricity to run the pumps in 126 gas boilers.
If all the gas boilers in 26 million homes in the UK were changed to ASHP’s it would cost a staggering £520b. That is a quarter of the annual Gross Domestic Product of the UK, and the government want you to pay most of it.
If all the gas boilers were changed for ASDP’s the electricity demand would be 165GW, which is four times the maximum national grid generation, and complete fantasy land, unless of course you have a magic renewable electricity generator.
