First of all you need somewhere to put the heat pump. There are a number of factors that will determine its optimal position.
An air source heat pump will need to be fixed to a wall, or placed on the ground. This needs to be in a position where the pump can continuously draw in air. It’s also best to have the pump fitted where there is plenty of sunshine.
To make best use of an air pump, it would be advised to have a well insulated property. Because the pump will produce heat a lower temperature, you need to ensure there are no draughts that the air can escape through. This will optimise its efficiency.
In terms of annual bill savings, it all depends on what energy source you are replacing. For instance, replacing electricity or coal will easily pay you back your initial installation fees.
However, heat pumps, whether ground or air, are not recommended for homes on the gas network.
You’ll also need to think of how your heat is distributed. Heat pumps are more efficient for underfloor heating than radiators, because of the lower temperature of heat produced.
By combining the installation of a heat pump with the development of a new property, it’ll lower the initial installation costs.
