Original Note:
Heat pumps are 300% efficient. That means that every 1kj of energy input as electricity produces 3kj of heat. The best gas boiler is around 80% efficient and that declines with age. Zombie boilers can often be as low as 50%. Electric boilers are 100% efficient. https://bakerhomeenergy.com/kc/how-are-heat-pumps-more-than-100-efficient-bk/#:~:text=In%20ideal%20circumstances%2C%20a%20heat,electricity%20required%20to%20power%20it.
