Hi all,
I need some advice about my heating problem. We bought a 1970's detached house (5 bedrooms) last year and the first thing it needed was a new boiler. We fitted a Gloworm Ultracom 30Cxi as well as a timer unit and room stat set to 20 degrees. There are a total of 15 radiators on the system, which all but 2 being operated by TRV's set to positon 3. We have tried to have the heating on a timer, we have also tried to run it constant on a low output from the boiler. The net result is that I am averaging, and continue to average 13,000 kwh per quarter on my gas usage. This has seen me pay circa £3600 for the last 12 months for gas.
Things to note:
Ground floor is suspended wood beams, with a total of 22 air bricks venting the underneath of house. flooring is very cold as a result.
We don't have all 15 rads on, it is closer to 10. All radiators are Type 21 and quite old but warm.
The previous owner had gas hob, 2 gas fires and gas tumble dryer. we have removed all pipework for this, but never had the gas pressure to the boiler changed.
There are lots of Hardwood double glazed windows (with wooden blinds fitted where possible), which I've been told by a neigbour were fitted in the 1980's. Some are rotting, but would I lose that much heat this way?
Our previous property was newer, but of similar size and our consumption was 1/3 of this and we had the heating on all the time.
I have sat here and monitored for the last hour the heating and we have consumed 1m3 of gas. Currently since I first looked on Monday, we have used 18m3 of gas. I have used 3 times the average of the houses in the area for gas consumption in last quarter
The house is currently freezing as I try to work out the issue. There were draughts which I have sealed. I had British Gas out who said I had enough loft insulation and that my walls were cavity insulated. On the latter the guy pointed to some holes in the walls about 2 metres up and said it is. I have drilled 4 holes through the wall to put in pipework and know found any insulation.
I realise I have a problem but I don't have a solution but lots of theories...
Could the gas meter be wrongly calibrated?
Could the boiler be 'running rich' with the removal of the other appliances?
Is it really cavity wall insulated?
Should I seal some of the airbricks?
Do I need to change the glazing
Should i accept its just a cold house?
Thanks for any advice
