Hi, it's a yes and no really!
I have had WB out, they hooked a computer up and inserted probe into flue and measured a few things. Result of which appears that boiler is working fine. We range rated the boiler to a more suitable level for the output (50%) and this stopped the cycling but...
I have just spoken to WB technical support, and the chap was very helpful, he talked me through range rating the boiler, which we dropped from 88% to 50%. I have been monitoring boiler since the change but unfortunately it is still cycling whilst room temperature is nowhere near setpoint...
it doesn't come up with a temperature, it shows what would be an 88 but with the vertical bits removed, so basically i end up with 3 stacked horizontal lines, twice over. i just tried it again but had to abort again as the flow temp rose to 95 deg and it sounded like boiler was literally boiling...
1. room by room heat loss, and a double check against rule of thumb figures, happy that radiators are sized correctly, certainly aren't undersized at all.
2. i entered this setting, but wasn't clear how to set the rating. the only parameter showing was the flow temp which was increasing...
thanks for your response, i previously had the flow at 70 deg and it was cycling, so yesterday i turned it up to 80 to see if this made any difference and stop the cycling, it's too early to say if it has made any difference though. i am satisfied with the heat loss and rad sizing calcs...
on the basis that in 10 years of house ownership, i have never used more than £45 a month of gas but have been averaging £100 for the last 3 months in the new property. Obviously bearing in mind prices have risen significantly lately, i only used to use £20 a month for first property with the...
Hi guys,
Have recently had a new central heating system fitted to an old property I bought. The new system has approx 13kw of radiators at 80 deg flow, Danfoss TRVs and lockshields, and the existing Worcester Bosch Greenstar 37 CDi condensing combi boiler has been re-used as it is only 3...
