    Improving the efficiency of heat pumps is going to be tricky.  They should be able to deliver a COP of up to 4, but only if the heating system inside the house is very well designed (underfloor heating or big radiators), and if the heat source isn't allowed to get too cold.


    Air source heat pumps are always going to be at the mercy of the weather.  That's not too bad in the South of England, but in the North of Scotland, temperatures below freezing aren't exactly unusual.


    A well-specified ground source heat pump should do better.  But in small urban gardens, that means bringing in a drilling rig and drilling at least two deep boreholes to get a big enough heat source.
