New Boiler problem/leaking pipe

Linnear

New replacement boiler installed 3 weeks ago. 12 days after installation, had problem with water pressure in new boiler.

We have today had the boiler manufacturer's engineer visit and he's tested the boiler and said that it's not faulty, but in his opinion we have a leak in one of the pipes in our concrete floor downstairs. He's turned off the central heating overnight and will return in the morning.

We have house insurance that covers this sort of thing, but how do we stand?

Our own opinion is that we are being strung a line. As we had no problems before the replacement boiler. We were told before fitting that we had a pressurised system, but the engineer that came today told us that that couldn't be the case.

The house is only 22 years old.

I'd be interested in any helpful advice as to what we do next, as the engineer is going to come back in the morning to turn the heating back on and see what happens to the level of the water in the boiler and in his own words, that he will then hand us a card saying that he called and nothing wrong with the boiler, so basically we'll be on our own.

So what was your old system, and what is the new? Make/model of boilers, tanks etc?
fI you've gone from a conventional vented system to a combi (you imply that the new boiler is a combi), then it is perfectly possible that the increased pressure could cause a leak, as could the flushing process that was presumably carried out. Was it power flushed?
Low pressure on a combi has 3 potential causes, 1) faulty PRV (which will be visible with a discharge from the overflow pipe outside), 2) faulty or underpressured EV, 3) leak on the CH circuit. Has your RGI checked and ruled out the first 2 (which seem unlikely anyway on a new install)?
If it's 3), then the engineer is correct in that the fault is not down to them.
What is the installer's take on this-you don't mention them?

make and model of old boiler..did you have a hot water tank? who fitted new boiler?

Thankyou for your replies. We've now had the Boiler Manufacturer's Engineer out and the new boiler isn't faulty. The water level had gone down on the boiler gauge overnight that pointed to a leak in our pipes somewhere.
We are now waiting to hear from the boiler installer to see where we go from here.

I can give more information on here once we have spoken with the company who installed it as there are a number of issues that we aren't happy with, but may need dealing with legally.

unless he isolated the boiler from the heating system & left the boiler pressurised he can't say if the boiler is or isn't at fault, if he did & the gauge on the boiler dropped then it's the boiler

You still haven't told us make/model of boiler and what system it was converted from.
