MY 3 bed semi has always been chilly.
7 yrs ago I decided to replace the heating system.
I was advised to get a much bigger boiler and was recommended a WB CD42i (42KW) combi.
All 7 rads in the house were replaced. Overall cost was £5k
Firstly I should point out that I have a one-pipe CH system
Problem is that when the heating comes on, the rads start to warm up, then the boiler switches off for a period of time (even though the stat is still calling the flame) and the rads start to cool. Then the boiler comes on again and the rads start to warm up, but then the boiler shuts off again, so the rads never get properly hot and with outside temps around 5C it will take approx 16 hours to raise the temperature from 16c to 22c. So it's nice and warm just as I go to bed!
My gas bill is frightening!
Any advice much appreciated
Thanks
Pete
