Hi all
I'm brand new on here and discovered this site while trying to find a user/installation guide for a ideal classic ff350.
My friend has just bought a house for his Son to use while at Uni, the house was ex council and had quite a recent [looks recent, few year's maybe] central heating and hot water system installed, the heating system had been completely drained down, rad's tanks, boiler, everything.
On arriving we set about filling the system and bleeding everything, this took a good half day to get all the air out from everything we could find with a bleed nipple, with the system filled we fired the boiler up for the first time. It fired up instantly and ran for quite a few minutes before shutting itself off, we waited briefly and tried again and again the same thing happened.
If I list out some of the things we've tried to rectify this problem perhaps you guys could could suggest obvious things we've missed and could also try, I used to design and build commercial catering equipment including gas hot cupboards/bain maries etc so so have some experience with gas and burners but am not a corgi guy.
Here's a list of what we've tried so far.
A sensor on the right hand side of the combustion chamber was removed [looked like a thermocouple but controlled the power in?] the boiler fired up then it tripped out again.
The sensor on the left hand side of the combustion chamber was removed, boiler fired up but was obviously running hot so was shut down quickly.
We found the the water pipe from the top right got really hot but the pipe on the left never did, also on the tank the top of the coil pipe got hot but the bottom never did?
We figured we had a circulation problem which was causing the boiler to overheat so again thought it to be air, we went through the whole system to try and expel air and although there was a bit at various nipples it made no difference so we turned our attention to the pumps.
This system has two pumps which were removed, stripped down [they were of a magnetic impeller type] cleaned spun freely and refitted, turned on and heard to be running [we assumed they both couldn't be stuck and humming because they weren't moving] but made no difference to the boiler staying on any longer than a few minutes.
We cracked joints open all over the place to check water was present and it was yet still it seemed we had a circulation problem which was causing the boiler to overheat and shut off?
The system was we presume installed by professionals who did the boiler and central heating at the same time, the system has run in the past and worked fine, the pump bodies look reasonably new [spotless] and we struggle to believe they've both gone at the same time.
The boiler does hot water and the central heating, it only has an inlet and outlet pipe on the boiler so none of the pressurised systems that I'm familiar with, the tank was new in 2003 and is in a soft water area, the central heating pumps appear to be running as the can be heard yet the water won't circulate?
Is there sort of valve on the boiler that is not obvious to the untrained eye that could be stuck? is there anywhere to bleed the combustion chamber?
Help please guys, we had a day and a half scratching our heads, we don't know if it's a plumbing [air in system] or a boiler problem and would really appreciate some guidance.
Thanks for reading this and I'm off to have a good look round the site
