Our victorian house has an original loft room. We had a re-roof done 9 years ago, and took the opportunity to have them install insulation above the ceiling before felting and slating the roof. The job does not appear to have been the best as the chimney now needs re-pointing again, and...

Thanks for the replies - I measured the temperature of the walls in our house, and found the side with the empty house next door is only 15C whereas the others are all 21C. Any tips on how to stop the mold in the wardrobes? I considered cranking up the heating to eventually warm the wall...

Hi, The house next door has been empty (and therefore stone cold) for many years and we have a constant battle with mould growing in our hallway. The main bedroom has built in wardrobes and the clothes are getting ruined with mould - suddenly appeared in the last month. Humidity levels...

Thanks guys ! You were spot on with the sticky valve diagnosis. The intermittent fault happened again last night - ran the hot tap, luke warm water came out, however the rads were getting hot instead. It seems the pre-heat was also trying to heat up the whole system. Many thanks for...

Thanks for the reply :-) I'd put my bet on a faulty Thermistor, or perhaps a relay sticking on all the time. I eventually turned the boiler off completely for a few days because it was wasting gas running 24/7 ... I turned it back on 4 hours before the British Gas engineer visit (they were...

Weather's fairly warm outside, thermostat set to 20C, ambient temp 22C no need for CH to be on .... I have a Vokera Linea 7, the timer on the boiler is set to "OFF", and yet every few hours (mostly at night) the boiler fires up by itself and all the rads get piping hot and the house really...

Is my current system likely to work better with the pump turned up ? Would turning up the pump speed cause any other problems ? If turning up the pump is not an option, then I guess re-plumbing is the alternative ?

The main feeds in/out of the boiler are 22mm and have two mainfolds connected in series - both mainfolds are under the landing floor. I presume that one is for the upstairs rads and the other for downstairs. All pipes are 10mm plastic. I live in a Victorian house with high ceilings, so it...

Hi Guys, my system is a bit better after balancing, but would like to improve further if possible - I don't have the experience you guys have built up so would appreciate any advice you can give ... The boiler is in the bathroom, and the mainfold is pretty central in the landing. The smaller...

Thanks for the advice - I already spoken to the plumber about the problem, but he's too busy to come back and look at it for a few weeks. He said that it is normal for the bottom half of the radiators to be cold - which I think is bull, as the old radiators used to get nice and hot. Have...

I had a brand new central heating system installed last year, but am not pleased with its performance. The bottom half of my radiators are stone cold - the problem is with the downstairs radiators, upstairs ones get very hot. There are 9 radiators on the system, 5 upstairs and 4 downstairs...
