I have a boiler that is a year old, and I cannot get temperatures at home much above 18c (the old boiler was ok). I asked Potterton back to inspect the boiler. They tested the temperature, found it ok (80c) and said that I should keep it permanently on 'Max'.
The rooms are still nowhere near warm enough, even though the rads feel hot. I have a boilerman in next week to give the first service. I notice black sludge when bleeding so I am also going to ask him to flush this out.
Problem is who do I contact to perform a survey on any heating loss. The energy companies are only interested in selling you insulation. (I already have loft insulation - not 10 inches though - and I think my property is too old for cavity insulation (1920) also I believe that the cavity is there for a purpose ie to prevent condensation).
Who should I contact to test for draughts, measure heat loss, generally tell me what's wrong (I believe there is a thermal instrument that they can use to determine problem areas??)
Any advice would be appreciated
