Gas Boiler help

sandhu40

In 2001 installers were allowed more than a 1mb drop in working pressure from meter to boiler. The boiler is not to current standards but doesn't represent a danger.

New rules mean that nearly all boilers will run on minimum 22mm pipework now unless the boiler is sitting on top of the meter. Your installer can calculate pipe sizing and pressure drops for you to save costs.

Thanks so much to you both for all the advice.

I am going to get at least 2 more quotes before I decide what to do as from what you say this guy is a bit on the expensive side. I am also going to do some research on boilers to see which one is best for my house.

I feel much more confident now about what to ask about - I think I may get someone else to do the job as I am not sure if this guy really wants the work - apparently there is tonnes of work in the area!

Will let you know how I get on next week.

Many thanks again!

Get another couple in to look at the job.

You were posting as I was typing. Good plan.

The information that I provided this morning was not incorrect as I have written out the list of buried pipeworks below. I have good information that has been quoted from the CORGI Gas Regulations Handbook as follows:

Ventilation:
A duct is a purpose-designed enclosure containing gas installation pipework. They may be vertical or horizontal and must be ventilated to ensure that any minor gas escape does not cause the atmosphere within the duct to become unsafe. The level of ventilation is not intended to clear a major gas escape arising from damage or failure of a gas pipe, but to allow the gas to be detected. The minimum period of fire resistance of the duct should be 30 minutes for buildings of not more than three storeys.

The rules and regulations for buried pipeworks are as follows:

1. Must conform to regulations and recommendations for laying of service pipes.

2. Must be protected from corrosion - up to 50mm (2") dia use pipes with factory applied wrapping. Joints or exposed sections to be wrapped after soundness testing. (usually with self adhesive P.V.C.).

3) Any exposed sections should be painted not wrapped.

4) The route for underground pipework should:-
a) Avoid proximity to unstable structures.
b) Be clear of walls which retain materials above the level of the ground in which pipes are laid.
c) Not pass under load bearing walls, foundations and footings.
d) Not pass through large unventilated voids.
e) Avoid areas of recent infill.
f) Be laid at least 3m (10ft) from any building until turning to enter the building if the operating pressures within the pipework are between 2 and 5 bars.

Hope this helps to clarify what I was trying to explain earlier on, I have also been informed that if you do decide to run the pipes under the floorboards this has to be one continuous length without any joints otherwise it needs to be a pipe within a pipe sleeve.

What have CORGI got to do with it?

Is under the floorboards a purpose made duct?

Please don't post advice on gas related issues if you are not a Gas Safe Registered engineer at the very least tell the OP that you're not so they can discard your incorrect advice.

If you are a registered engineer then God help us all:eek:

I hate picking at other peoples posts but yours was plain wrong

gas4you

Most of the info in this thread is totally incorrect and should be ignored, well everything apart from Razors post.

This forum seems populated by armchair gas experts who at best give wrong advice and at worst is just plain dangerous.:mad:

There are plenty of cases whereby the supply network cant supply the recommended working pressure anyway !

Hi there. It seems like there are some experts on here so I wondered if anyone can advise me about my boiler, a Baxi Solo. The cover on top of the boiler has no screws holding it in place so it just rests on top of the boiler, usually without any problems. However, we noticed that the boiler had not come on this afternoon although it sounded as though it had switched on normally. When I checked the boiler, I found that the cover had fallen onto the fan and that as the fan had been trying to rotate with the cover resting on top of it, a couple of blades had broken off. As soon as I removed the cover, the fan began rotating normally and the boiler fired up. However, I wondered if it is now safe to use as the fan has two blades missing? Will this affect the performance of the fan? Thanks for any help, this has been a very reliable boiler, despite its' age and I really could do without any hefty repair bills at the moment!

Suggest you delete this post and start a new thread specific to your problem. Otherwise you have hijacked this thread, the answers will get all mixed up and confusion will reign.

Cheers

Oooh, sorry, I thought I had started a new thread! Will move now, ok?
