Who do I sack heating guy/builder?

fraser12 · 2 Jul 2009

First thank you to Gas4you for helping me out with boiler it was thermcouple, which in fairness heating guy did say and he replaced it and boiler works.
I have had an loft conversion and added new radiators in rooms.
Heating guy fitted new rads couldn`t fill them up, they justn`t wouldn`t fill!
Builder has walled in small heating tank with no access.
Heating guy used hosepipe to fill rads but water came out of overflow outside.
Builder refused to open wall and argued it was heating guys problem.
Heating guy opened up wall anyway when builder was gone and this is what I he said I wrote most of it down.

When bleeding radiators f`e tank fills up.

f/e tank for heating is 6 inches lower in floor than highest radiator.
Vent pipe has been hooked over side of tank, should be higher than tank.

F/e tank has to be taken out and placed higher than rads and vent pipe also redone.

Builder came back through a fit and refuses to move f/e tank or open wall says problem is heating guy`s plumbing.

Why is tank filling up, why can`t radiators be bled and does tank and pipe need to be moved or do I sack them both and get someone else?

If someone will explain in simple non plumber/builder terms I would be most grateful.
Thanks again for your help.

you say tank has been moved and vent pipe re-done etc.

did the builder know the loft was going to have radiators!!!

the engineer has told you the problem why would you sack him

!!

simply put the water in the tank cannot flow up hill to it needs to be raised above the highest radiator

Sack them both and get a Heating guy. Gas registered etc. who can safely convert to sealed system- if it`s possible with the boiler you have.

Tank moved couple of inches by builder, then he walled it in. Heating guy fitted rads/ fixed boiler/gas safe registered.
Builder knew rooms were getting radiators.Builder supposed to be plumber also. He lay pipeswork in plastic for heating guy to connect to.
Why is tank filling up?
Can`t afford to fit whole new system at moment. Thanks. I only wanted a couple of extra radiators!

as already said the tank needs to be higher than the rads.

Boiler is Glowworm 45/60 floor standing balance flue, can this be converted to sealed system without changing boiler?

because its lower than the rads you are filling with a hosepipe! it needs to be higher as seco has already stated

as to who's fault it is it's whoever did the"spec" on the job but I would suspect that you have employed the builder who has subbed out the work to the plumber in which case your argument is with the builder.Also anyone who would block in anything that requires access for servicing is a complete moron

Nope boiler far too old and wrong type for sealed system

fraser12 · 2 Jul 2009

Thanks, so I am going to sack the moron builder. I need to have tank lifted, ok, understand that.
The hose that was used to fill radiators was disconnected, when boiler was fixed, air was found in top radiators, when bleeding these the f/e tank started to fill, why was that.
Why is boiler wrong type for sealed system? thanks for answering.

The f&e tank should ideally be a minimum of 1M above the highest point in the system.

I presume your boiler cannot be used for a sealed system, as itdoes not have a built in overheat stat, seperate from the boiler stat.

As previously stated the tank has to be above the radiators, I do work for some builders who do loft conversions and 'most' builders don't understand about tank locations, I usually need to tell the builder what is required with regards the tank locations, (assuming i get on the job before they start framing everything) then he has to work around it, thats if the customer does not want to change to a sealed system.

Usually we put the tank as high as it will go on the chimney breast wall, then build a false wall to hide the tank which also contains the brickwork for the chimney, so is no great loss and doesnt really reduce size of the room. Then leave an access hatch with a door at the top of the stud wall. Even then the tank wont be much more than a meter above the radiators if you are lucky, so you usually have to fill rads with a hose pipe anyway.

In this case is sound as though the builder has just gone and 1st fixed everthing then when its too late (after everything is enclosed) called the plumber to finish off. So I would blame the builer, however if the plumber was involved from the start of the job then he should advised the builder about the tank before he started framing out the inside.

I think the best thing to do is get the builder and the plumber back and try sort something out between them, plumber does what he needs to do, and builder does what he needs to do, to get it finished, sacking either or both of them off the job wont get the issue resolved, and will cost you for someone else to fix.

Ok, great, thanks to all for input, understand about tank needs to be higher, but why is it filling when bleeding rads (only top ones?) what`s sealed system mean, my boiler has stat on front case. Gas4you could you tell me where to get the literature for this boiler have tried Glowworm/internet but it`s old. Thanks again all.

The reason it overflows when you open a bleed valve is probably because the plumber has (accidentally or intentionally) created a partial vacuum in the system that's maintaining the water level above the F/E tank.

Opening a bleed valve will allow air into the radiator, breaking the vacuum and allowing water to run back to the F/E tank, which then overflows.

You wont get instructions for it too old its just not designed for working on a sealed system
