Their fine in the roof providing their not in a cavity

Hi there, Once Cadent know about an issue it needs a resolution. If you don’t want an upsized service you can sign a waiver so no work will proceed. It sounds like you need a larger diameter service. There are many reasons why you existing service might be inadequate duelled with next door , old steel , inserted or not enough capacity in the main. Your new boiler requires a large amount of gas on startup which your gas service is struggling to provide this is very common fault now.

Thanks for the replies, fortunately insulation cost of the ASHP will be minimal also I may be able to get hold of one at a very reasonable price, I’m more thinking of the monthly running cost as it would be running all the time. we had CH before the underfloor was installed but couldn’t get enough output from them due to not enough wall space due to doorways , staircases etc . I guess I would like to know what a monthly cost of running a ASHP would be for underfloor heating only? If any one could help it would be much appreciated .cheers

Hi There i was hoping someone could share some wisdom! I currently have a uponor minitec underfloor which has been fitted to our hallway, bathroom and front snug. The problem is it was retrospectively fitted and there is no insulation fitted, it has a thin screed of 20mm and has been working well however the cost of running it is eye watering so we haven’t had it on in 2 years! The house is listed, old with sash windows and leaks like a sieve! We have 2 x 30kw boilers connected to a low loss header for CH heating (upstairs and some rooms down stairs ) and water. My question is would it be cheaper to buy an air source heat pump to run the underfloor heating only on a seperate circuit only and let the boilers do the hot water and CH radiators. I believe the air source heat pumps can heat water to a low temp which would be good enough for the underfloor heating ? Any suggestions would be much appreciated thanks
