Ironically it’s self evident from his own advice that you can’t get 2 or 3kw of heat out by putting 1kw in.
He also predicted the government’s stated aim of artificially increasing gas prices to match electric.Bearing in mind a more than 100% increase in the price of gas.
As for a fridge in reverse I’ve never seen a fridge yet that has great big fan or any fan in its system and certainly doesn’t create 2 or 3x as much energy as put in.
On that note if it was true we would obviously be using massive heat pumps instead of nuclear power stations or wind turbines to generate electricity.
Last try.
If electrical energy is converted into thermal energy, then yes, 1kW of electric will convert to 1kW of heat. (Assuming 100% efficiency)
A heat pump is not doing this. A heat pump could indeed be run using a petrol V8 (bet that woke you up!) but for simplicity we are discussing those run by electric motors.
A heat pump is not converting electricity into heat, it is moving heat from one place to another place. It is not “making” heat.
It works by taking heat from a cooler place, (inside a fridge/outside in the winter) and depositing it in a warmer place (outside the fridge/inside in the winter).
1 kW of electricity can move up to 3kW of heat.
I repeat that 1kW of electricity is not being converted into heat. It is moving heat.
It is not a case of “creating energy” in any way.
Conservation of energy is retained at all times. The heat lost by one place, (inside the fridge/a winter day) is the same as the energy gained by (outside the fridge/inside the house) another place.
