With a solid walled place like yours (and mine), the heat losses will be such that the radiators would need to be hot in order to provide sufficient heat. This means that the COP (roughly: heat out/electricity in) of your heat pumps will be close to 1. That means you will be paying electricity prices for each unit of heat. That means it would be a very expensive way of heating your house, even if the installation costs were zero.
