Well - it's all mended and the culprit was simply sludge that was keeping some valve open continuously so boiler kept running and the 6 core on the heat exchanger overheated.
I was very surprised as it was power flushed just 3 years ago and the heat team chap last year said it was a clean...
Yes Correct. 2 totally independent systems - nothing is connected from one system to the other. Each has its own boiler and pump.
Today is the day that Heat team are coming to mend it - it's been a very long week.
I highly doubt its anything to do with chemicals as the system has been...
Gas 112 - no there are not TVR's on all radiators - I'm changing over to new radiators floor by floor.
DP - Thank- you , I will pose these questions to the Baxi heat team chap on Thursday and will then listen for whether there is a delay or not when it fires up. Currently the whole system is...
Ah ok. I'm beginning to understand this I think . A bit like a modern Ferrari engine trying to power a tiny old car and constantly revving but not being able to use its power ? Thanks.
I'm sure you're right about the radiators.. Would changing the remaining old single radiators to new...
Hi ,
Its come back as 34.
So I need to get the new exchanger put in on Thursday by the Baxi heat team and then a Registered Gas Installer to come and range them both and that should help ?
Meanwhile I've turned down the functioning one to just above low and will see if the radiators...
Thanks Mehran for responding
One is a 24 and the other a 18 but they are the same model and make of boiler.
The 24 does all the hot water plus 9 radiators on 3 floors at the back of the house
The 20 does 9 radiators on 3 floors at the front of the house
Does that sound very wrong...
I had both systems powerflushed prior to installation and both times they've had to drain down, each system has been clean without sludge .
I know I need magnets at some point added on, but the heat team man said that it was not in need right away as the systems were so clean , so I've...
Hi
I'm not attempting to do any DIY but wanted to get some advice and opinions.
I had 2 brand new Baxi solo HE boilers installed in June 2010. one a 24 and an 18. I had 2 old baxi's removed and replaced with 2 new ones - no alteration in anything else.
No issues at all until April 2012...
