Hoping someone might have an answer here....
Moved into the house last year so don't have any installation service/history...
I had an additional rad fitted about 8-9 months ago the pump ran at 45W (way too noisy) when on III and 19W (Quiet) when on II. Just recently British Gas came out to fix a leak on on a bleed valve near the boiler. I've since noticed that the pump sounds a little noisier than before and is running at a lesser power draw.. ie 33W on III (still too noisy) and at 13W on II which is noisier than before but bearable. All rads heat up but it feels a little slow
What else can I tell you?
Boiler is an Alpha CD18R
Boiler stat is set to 6
Its an open vented system with standard hot water tank
The are 12 rads
Primary concern - I'm wondering is 13W at setting II still a reasonable speed rate for this pump to run at for my system?
What might cause the pump to run slower?
Is there anything I can be trying to get it back to its previous speeds?
Thanks in anticipation of your help
