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!)

    Rust joints only worked well for water, steam, or gases containing water vapour. Prohibited for gas supply pipes within buildings but sometimes used for gas mains in the street.

    Drifting slightly O/T, I recall a story of an electrical engineer, without railway experience, who had to supervise the construction of a tender for a steam locomotive* The water tank leaked from the joints. This was cured by the addition of fine iron fillings to the water which was stirred around. This promptly reduced the leakage as the iron filings blocked up the holes, after a few days leakage was eliminated as the iron filings rusted and expanded.

    *The locomotive was ordered from England, and shipped to somewhere in South America. It arrived without a tender and was required to be put to use urgently. It was common to supply steam locomotives WITHOUT a tender, this being manufactured locally, or the tender from the previous engine being re-used.

    Drifting even further away - presumably Bar's Leaks is similar. I always worry that it could be Blocks Radiators.
