We're trying to weigh up the pros and cons of the above for our new 175 sq metre self-build and would be grateful for any contributions to help our decision. We will also be using thermal solar panels and an independent log burner. The house will be Code Level 3 or thereabouts.

Savings will always be made with air source heat pumps against oil in this country. We have a mild climate even in the winter and the best air source heat pumps will have c.o.p ratings above 4 and seasonal ratings of 320%. You will also have a lower carbon footprint.

I Got rid of my oil boiler(when oil prices went sky high) and had a NIBE Exhaust air heat pump fitted 2 winters ago, it draws in air from air ducts fitted to ceilings rooms in house and so works as a ventilation system as well as recovering energy from ventilation air, This system doesn’t suffer the same as external ASHPs as the intake air is higher being at room temperature, this is also higher than GSHP temperature. My house has radiators upstairs and skirting heating down stairs. I also have Solar water and if I had more money I could have had it incorporated in to the NIBE.
Please note all these systems need a secondary heat supply, immersion heater or boiler, to help out when extra heat is needed when its very cold or you draw off a lot of hot water for baths and washing.
