central heating combi boiler problem
 
Hi
I wonder if anyone can help me .
Our old combi boiler was replaced in December because the water
jacket
was leaking & could not be repaired [ Grant Boiler], soon after
fitting the pressure dropped again, Engineers came & found a small
leak.

One again the pressure is dropping, i am now told itmust be a leak in
the house, probably under the floor boards & nothing to do with
them .
The problem did not exist before the new boiler was fitted


On top of that i have now also had an account for commissioning the
boiler, this was not done at the time of fitting.


Could i question why a separate expensive trip was required for this,
Thanks
Wally

I can only suggest that you have a look at easymaintain.com as there
are a lot of useful tips on the site, and you could ask them and they
do reply !
I had a central heating problem and it was sorted thanks to them

Take a look at the SealedCH FAQ.

As for the companies pricing structure... on what basis did you engage
them.

Hi Ed

Thanks for your reply,

on what basis did you engage them.

To fit a new boiler i am not complaining about there fees as such,
only i had a separate fee to pay when they came back to commission the
boiler , i wondered why this could not be done at the time it was
installed , not about 3 weeks later

They have called again to day, been under the floor boards, as far as
they could , but cannot see a leak
Yet the system, lost 4 bar over 2 nights, which means if it had been
set it at 1 , it would be nearly empty, i has now been set at 2 bar

They have doubled checked the boiler, found no leak except a very
small drip, they have now put a sealent into the system to stop any
leaks. Hopefully
I will do as you suggested & check out Take a look at the SealedCH
FAQ.
Thank you so much for taking the time to reply to my question

What a wonderful site, nice to see people take time to help others
Regards
Wally

Did the old boiler also have a sealed system, or was there a header tank
for it in the loft?

Converting to a sealed system can result in the heating circuit being
more highly pressurised than previously. One thing that often gives out
are old lockshield valves. Were any radiator valves replaced?

One again the pressure is dropping, i am now told itmust be a leak in
the house, probably under the floor boards & nothing to do with

Which is to be expected on some older systems...

On top of that i have now also had an account for commissioning the

Did you pre-agree a all in price for the work?

I strongly suspect one (or more of) the following:

Not all of their manual employees hold CORGI cards. So they send out their
registered operatives to check things over and sign off the paper work.

There was some minor part or component to the entire system which prevent
the installation being signed off until later.

They are making an excessive deal about commissioning and are using it as
a lever for more margin.

They wish to explicitly pass on the administrative costs associated with
self certification to the customer and use this mechanism.

Hmm, quotes like that make me very nervous and suspicious about what I
am being told. A "very small drip" is quite enough to cause the
pressure to drop substantially. 0 pressure does not mean the system is
empty, is simply means there is insufficient water in the system for
it to be under pressure. If you have a small leak, if you pressurise
the water, that leak will be a *little* worse.

If the small drip is occurring on pipe work installed by the company
who fitted the boiler, the work IS substandard and completely
unacceptable. They should fix it, now, and for free.

It is possible a leak has developed elsewhere in the system, even
though your previous system retained pressure. But I would say it is
unlikely. Therefore I think adding a 'leak stopper' to the system is a
bit of a con, to fool you into thinking they are being helpful. Try to
identify any water (no matter how little) occurring on pipe work that
they have installed; this sounds like the cause.

Regards commissioning, it is very difficult to advise since I do not
know what you agreed before hand. Having said that, 'commissioning' is
the bit that is signed off (and your boiler warranty likely void
without it); therefore even if it was not agreed beforehand I think it
reasonable to assume this would be included in the installation
costs.

Don't let them get away with it.
