That is a very fair comment and as a professional engineer, one I wouldn't argue with. That is why with my background in the nuclear power world I ask before I act. I always check, check and check again. I just have. And you came up trumps.
Thanks AlanE for those comments. Does asking a question indicate incompetence?
The boiler is an Ideal - Mexico Super 3 rated 20.5 - 23.4 Kw. Is it suitable?
Thanks both this is really helpful.
The house has 2 floors plus rooms in the roof space plus a basement.
The boiler is in the basement and there are radiators in the top floor rooms. The Vessel has got a PRV as part of the expansion vessel control kit and the gauge is on the PRV.
The boiler...
Thanks for that. I should perhaps have said that the house is a 3 storey one with the boiler in the basement so the static head must be over 25 feet. Does that make any difference?
Can someone tell me what the pre charge pressure should be for an expansion vessel on a heating system. Do I need to take the static head into consideration?
I am converting my son's heating system from the original header tank system to a sealed system and I can't find any info on this subject.
