      Which can be solved by installing a bigger heat pump. No boiler can compete with 300% efficency.

        Which brings us back to efficiency, this time cost efficiency.

        If the heat pump costs more than insulating would have, then obviously you’ve not so much solved the problem but rather made it bigger.
