New boiler installed.

[Minty!!]

Had a new Worcester Bosch 38 CDi fitted today. The installer ran the boiler through it's start up process and ran the boiler at a temperature of 90 degrees for nearly an hour. I was a bit shocked at this and was expecting the central heating system to blow up at any moment as we would normally run the system at around 25 degrees.
After running the system at that temperature for that length of time he then turned down the temperature and announced their is a leak somewhere on the system. All pipework is now concealed making the leak difficult and expensive to find. The system was pressure tested to mains pressure for around four days prior to floors going down.
I am left wondering whether this boiler installer was right to run the system at such a high temperature for so long.

4 days... that's a long wait...................................................................................

Everybody seems to be questioning installer however he found a leak for starters and hell of a lot of installers i know don't even test the boiler properly.

At least he tried .

Exactly! I think the installer covered his backside. As for the original pipework testing - 4 DAYS?!

Hope he got paid.

its not clear why the pipework was tested for 4 days or who did it, what is clear is that the boiler installer tested the system because he had shunted onto existing and found there to be a problem, I think that you got a good installer and should either ask him his advice as to whom is responsible for the leak and how to go about getting it rectified.

It's his discretion.

I say fair play to him for actually testing it. People are alway shocked when a leak appears on 30 year old copper pipework...

Did the same installer who fitted the Boiler also fit the pipework?

Is the now covered over pipework Underfloor within the concrete or just covered over by wooden floors?

If UFH in the concrete / screed was the pipework held under pressure whilst the concrete / screed was laid?

Also am I missing the point but if it was constantly connected to the mains what is this going to prove? if there is a leak then the mains pressure will make up the shortfall was there any sort of pressure gauge attached??

Maybe they were hoping to see a wet patch...

Beat me to it, I was going to post " I am always hopeful of a wet patch"

I'd say the installer was spot on, probably ran it for an hour at max with chemical cleaner in the system (x800 or similar) to comply with manufacturers guidelines as he couldn't be sure it had been cleaned previously
I'd keep his number if I were you and liase with him in the next course of action to get the leak(s) resoved
