Heat pumps are able to do this to an extent, as a consequence of which the amount of heating is limited and for optimal efficiency these heat pumps need to be combined with low temperature heating systems, which are typically not provided for in older houses.
  • low temperature heating systems which are typically not provided for in older houses.
  • heat pumps When replacing oil or gas boilers with heat pumps, the complete heating system of a household would need to be replaced, reducing the desirability of these heat pumps.
