Hi all,
Happy new year.
I have a gravity back boiler CH and hot water system and I need a bit of advice....
I called out a Gas contractor last September to service the boiler. He faced issues with getting the boiler going again after switching it off to do the maintenance. In doing so several things were tried and most of the knobs were played with. Long story short, I ordered a new thermocouple as the pilot wouldn't stay on by itself. That fixed the issue and on we went.
Now the system is in regular use, I had an incident on Xmas eve that left me without heating on Xmas day (pump stopped pumping). I had previously faced an issue with the pump which turned out to be the control module, which I replaced from another used pump I bought, so not to have to deal with draining the system, then all was well again, so I thought possibly due to the age of the components it's likely the same issue again. Anyway, given the time period, I was unable to acquire another pump on short notice, so I decided to give the pump a little love tap with the hammer half way through Xmas day. That got the pump going and saved the day.
I did notice once we were toasty again that the Pump and all of the radiators are getting allot hotter than I recall. I have an IR thermometer in the house and I measured the pump at nearly 85c and most radiators close to 80c or a little below that, but in the high 70's on average.
Searching online suggests CH radiators should be operating at 60c-70c Max.
So I'm left wondering, did some setting in the back boiler get disturbed when the Gas man was playing with knobs? - I do recall him mentioning that the flame of the boiler was a touch yellow when it should be all blue, so he adjusted the boiler to reduce (from memory) the Gas feed to obtain a better burn, which helped.
I'm wondering now if that had an effect in getting the water hotter all other things being equal, and what if anything I can do to reduce the CH system temp by 10ish degrees? I'm concerned it cant be good for the pump, not withstanding the radiators are too hot to touch for more than half a second.
I can provide more info about my system or images if anyone needs to see anything specific.
TIA
