I changed my old boiler to a condensing type at end of Feb. this year.
During the summer it was on water heating only and did a good job more economically than the old one. Since switching to central heating in the autumn it is using noticeably more gas than the old model, particularly when I turn it up.
All radiators have TRV's and although I have detected the roomstat is not performing properly and will need moving, I do not believe this will be sufficient to cure the problem given that the extra gas usage is up to at least a third more.
My gas meter was changed in August but I am told that it is unlikely to be faulty and that if I ask for it to be tested I will bear the cost if they find it OK.
Any suggestions ?
