Heat pumps move heat around, whereas radiators create it.
The “efficiency” of heatpumps relates to heat they import into a system for a given amount of power, compared to creating heat with that power. They are not generating that heat. They are moving it.
Similarly, it’s much more energy efficient to use a wheelbarrow to collect ice and move it inside, than it is to make ice cubes in freezer.
What about heat pumps they have efficiency in the range of 200-300%
