I'll add my experience to the discussion. We have a 200 year old end terrace house in a village in North Hampshire with four double bedrooms, three bathrooms and with the end wall facing North . The wall insulation is non-existent but the loft is excellent. Our gas boiler was coming to end of life and wishing to go green and be a bit of a guinea pig for the village we decided to have an air source heat pump installed.
The survey showed the radiators were of adequate size except one which was swapped for a three row version. The 15mm pipework has stayed. We decided to change all the radiators anyway as they were over 40 years old and of the "slab of heat" types rather than the latest convector types. Especially as we didn't have to pay VAT on them. (wish we had done that years ago!).
The installation was completed in September 2022 and we are very pleased with the performance. During the -8°C week last autumn the house was toastie warm. I just finished checking the costs for the last 12 months. We have used 46% of the previous years energy at a cost broadly similar. We find the "smooth" heating very pleasing. The highs and lows of gas heating banished to the past.
Gas will only get more expensive and electricity cheaper.
As you gather, I am a definite fan.
