What an ignorant hitpiece and not one mention how his system was designed/engineered.
Heatpumps aren’t some magic. They have known performance numbers and if properly implemented do save a great deal of energy during conditions you find in Britain.
If properly engineered for your home, heatpumps will keep it toasty in 99.6% of conditions. If not, you can sue the engineer and have it corrected.
Of course many owners do not have the proper engineering done and make a mistake during design. Heatpumps are more difficult to calculate than a fuel or electrical resistance heater. If doing geothermal instead of air source, good engineering is even more critical.
If they didn’t hire engineers, they have nobody to blame but themselves if their equipment falls short. Blaming the equipment TYPE for their poor math is an utter joke...
Electricity cost about 25cents per kwh in England.
Running the pump to score free heat will cost you lots
The heat pump is always going to blow colder air than a combustion furnace. So it’s never going to feel as comfortable. It does make a robust AC due to the high volume of air moving.
