Hi all I am hoping to learn from your collected wisdom. I have recently moved into a large 120 year old house. We plan to be here lonmgterm 30+ years and will slowly refurbish each room etc. The central heatring / hot waster system is very old and seems to have had bits added / changed but not had a proper overhaul for a long time. There are 2 boilers in a plant room attached to the house but accessed externally. 1 boiler (15 years old) supplies the radiators on the ground floor and the hot water cylinder on the 2nd floor (via a 1st floor towel rail). Boiler 2 (20+ years old) supplies the radiators on the 1st and 2nd floors... There is a pump for the hot water that runs continouously and is very loud. It takes a long time to get hot water anywhere! There are no wall thermostats. Boiler 1 seems to have an issue with cutting in and out when the system is calling for heat. I have had an engineer round who says it is 'cycling' but not sure why without fuirther investigation. He thinks the cylinder is far too small and should be reolcated to next to the boilers and the circulating pump isn't funcitoning correctly. Rather than attempting top repair these issues I am wondering about investing in anm upgrade at this point to hopefully save money in the future. The house has 6 bedrooms (2 ensuite), 4 bathrooms, 3 downstairs reception rooms and a large 'office' on the top floor. The external walls are solid brick construction. It is mostl;y douible glazed. I am fitting secondary glazing and will add insulation where possible. I am looking for recommendations.. Do I go for a new 2 boiler setup but with those boilers working in tandem / larger cylinder etc... a single large boiler... Solar panels and a air / ground source heat pump... Hoping to make the right choice now so I can decorate the rest of the house knowing I won't have to start lifting floorboards in the future.. I'd love any opinions! Kind regards Chris
