For a village hall, do you see any advantage other than environmental, in using a heat pump rather than gas for space heating, when Electricity is 24.847p per kWh and Gas 5.838p per kWh, both excluding CCL and VAT?

We have been advised to consider a replacement gas boiler. The current one was fitted circa 2004 and has a 100 kW output (120 kW input). The situation is not helped by it being a large diameter pipe system and cast iron radiators, likely original from when the Class II listed building was built very early 1900s.  (Some of the joints appear to be caulked lead!)

    Even the environmental benefit is not clear cut - not all leccy comes from renewables!

    What is the problem with the existing boiler? It is only 20 years old.

    I have looked at the economics of replacing my boiler at home. It takes a long time to repay the capital cost, even though a newer one would be more efficient. so over the medium term, it is not worth it.

    The existing radiators may not be suitable for the cooler temperature of the circulating water.

    By far the biggest problem (at least in my case) is the number of heat pumps required. There may be large 3-phase commercial ones, but otherwise the requirement may be for ten 3 kW input/10 kW output pumps. Where would they go, and if listed, would the planning authorities consent?
