So they are trying to force everyone on to heat pumps now (because we don't like Russia). Which are rubbish, noisy and super expensive to retro-fit. Yay that will solve all the issues...
But are >100% efficient compared to any electric heater. (Up to 500% efficient depending on conditions)
I suppose it will come down to if a gas turbine power station and transmission is more efficient than a traditional gas boiler (or even modern condenser boiler)
