Recent studies have shown than heat pump systems are more than four times the price of combi boilers for end-users to install.
The GMB union (where the B stands for boilermakers) is pressing Labour leader Keir Starmer oppose the roll-out of heat pumps as a low-carbon solution.
The Department for Business, Energy & Industrial Strategy (BEIS) recently published a report, prepared for them by Delta-ee, which provides a detailed comparison of the full costs of installing different types of heating system.
The report, , said that the costs of heat pumps systems to replace gas boilers for home heating are up to 拢27,350 per household.
Analysis of the report by the recently formed Gas Users Organisation concluded that: "An 8kW air source heat pump (ASHP) fully installed including fittings, buffer tank, cylinder and controls, but excluding the heat distribution system would cost 拢 8,750. In reality, it would be necessary to fit new radiators, and a 16kW ASHP fully including a heat distribution system would cost 拢21,550."
"Ground Source heat pump systems cost more,聽 for example, a 12kW GSHP fully installed including buffer tank, cylinder, ground works, controls and the heat distribution (underfloor heating downstairs and radiators upstairs) system would cost 拢27,350....This report clearly shows that gas central heating is by far the cheaper option for households."
GMB London region energy officer Gary Pearce said: "It is essential that the Labour Party under the new leadership of Keir Starmer study the policy implications of this new official government report on the costs per household of replacing gas for home heating with alternative systems using heat pumps and powered by electricity.
鈥淭he costs of the heat pumps systems vary from 拢21,550 for air pumps and 拢27,350 for ground source heat pumps.
鈥淭hese huge costs, plus the additional costs of the expansion of electricity supply needed to run them, should drive the Labour Party to conclude that this is not the way to go for low carbon home heating."
鈥淕MB London consider that existing central heating systems should be maintained and powered by natural gas until such time as it can be replaced by zero carbon hydrogen at reasonable prices. This GMB London view has been endorsed by GMB congress.鈥�
