Air Source Heat Pumps

Air Source Heat Pumps are a form of heating which extracts warmth from the air, even when it's very cold outside. This warm air is used to heat your home and produce hot water. 

An Air Source Heat Pump works in a very similar way to gas central heating. A unit is attached to the outside of your home converting the heat from the outside air, to room heating and hot water. 

For homes that are not connected to the gas network an air source heat pump can be a very efficient method of heating your home. With a saving of up to 40% on your energy bills, compared to heating your home with oil or electricity. 

Funding for Air Source Heat Pumps

Smart Grid Controls can provide funding towards the cost of supplying and fitting your air source heat pump, as we are registered with Ofgem as a nominated investor under a scheme called Assignment of Rights. Under the Assignment of Rights scheme, we can offer up to £6,500 up front funding towards the cost of your new central heating system powered by an air source heat pump.

Air Source Heat Pump Installation Process


Following an initial survey and arrangements to complete a heat pump install, the following procedure will be relevant to most installations.


Any existing heating and hot water system will be decommissioned and removed.

All existing heating pipework will be renewed to ensure correct flow rates for the new heat pump system. This will generally involve lifting flooring to the first-floor level of the property and installing the pipework under the floor. First-floor radiator pipework will connect to radiators from under the floor, Ground floor radiator pipework will be surface mounted in plastic trunking to required radiator positions.

New radiators will be fitted in place of existing radiators where possible; these may be larger than the existing and there may be the possibility of an additional radiator being required to certain rooms.

A new hot water storage cylinder will be installed and connected to the system; the heat pump will provide the required hot water for the property. Generally, the new hot water cylinder will be situated in place of the old hot water cylinder.

The heat pump outdoor unit will be situated in a suitable location, pipework and electrical cables taken via the most direct route to the required indoor positions. The pipework and cables will generally be installed in plastic trunking and conduit.

An additional consumer unit will be installed where required to accommodate the electrics for the heat pump system. All required wiring will be taken to the required locations, plastic surface-mounted trunking will be used to conceal any cables installed.

Upon completion of the installation, the system will be commissioned and tested to ensure correct operation. All necessary controls and use of the system will be explained during this process.

How Air Source Heat Pumps work

Heating Only Heat Pump Installation Process


Existing Boiler & Cylinder

  • Disconnect heating pipework from the existing system, blank off any unused connections and pipework, leave the existing cylinder and boiler in situ for hot water

  • Alter wiring and controls to suit hot water only operation

  • Install new pipework for the heating system – beneath first-floor flooring, drops to ground floor radiator positions in surface mounted plastic capping

  • Pipework and wiring to the outdoor unit location:

Option 1: beneath first-floor flooring to the outside of the property, surface mounted trunking and conduit for pipework and electrical wiring

Option 2: beneath first-floor flooring required location, drop down to ground floor level internally in surface mounted capping and trunking

  • Electrical wiring – from existing or additional (if required) consumer unit beneath first-floor flooring to required locations for controls and outdoor unit. Plastic trunking to be used for runs up and down walls to conceal cables

  • In case of the property being a bungalow, all references to first-floor flooring to be changed to loft space where available
