Am i right and everyone else wrong?

[whyme!]

New chimney being built to take multifuel stove. I think it needs a "proper liner" i.e a Pumice liner. Builder, hetas engineer and Building control say a flexible liner is ok despite my research saying a flexible liner can't be used in a new chimney?
Builder says 1st floor joists can be built into chimney and building control say not ideal but won't be an issue despite my understanding the joists should be trimmed and have a 50mm gap from chimney?

So who is right?

If a new chimney is being built I would expect to see rigid clay or concrete type flue pipe built in. I suppose a flexible liner could be used, it would certainly be cheaper but I cannot see the point, it is a bit of a bodge in my opinion and will not last as long as clay or concrete flue pipes. If it is your chimney what was specified? If you are paying you can have whatever you want.

As for the floor joists, just had quick look at Part J and timber can be built in but must be 200mm separation between timber and inner face of flue.

 

[whyme!]

Ok thanks for this, tech drawings just say a liner so not specific. I guess a flexible is really intended for old chimneys though.

If a liner works in an existing chimney, then it will work in a new one. But yes a "proper" liner would be better

The problem lies in your crap specification. You may expect one thing, and the builder has priced for another. Neither of you are wrong.

Structural timber should be at least 40mm from the outer surface of a masonry chimney. Part J, 2.18 (c) and NHBC guidance. It can't be built in.

Guess I need to refer building inspector to this then. So I am correct in part

I really do wish people would stop referring to HETAS qualified persons as "Engineers"

Unless the individual has attended and qualified from a recognised University having successfully completed a foundation type Degree (Bachelors at the very least) they are not entitle to refer to themselves as "Engineers".

I'm not suggesting for a moment that they are not qualified to design, Install and Test and certify their flu systems and I'm sure their contribution to safety is invaluable but please use a term that is more appropriate.

Perhaps Technician?

Engineer is not a protected title like architect or paramedic so they are entitled.

Glen, while the professional titles of 'Engineering Technician', 'Incorporated Engineer' and 'Chartered Engineer' are protected, the title 'Engineer' is not so anyone in the UK may describe themselves as an engineer, and you're just going to have suck it up.

The Engineer

 

[JohnD]

in the UK, respect has traditionally been claimed by those with ornamental qualifications rather than useful ones.

For example, the country's leading buffoon has a lowly Second-Class (2.1) degree in classics, and sneers at those better educated or more useful* than himself. He hopes one day to become Prime Minister.

In other countries, the abbreviation "Dipl. Ing." is proudly shown on office doors, organisation charts and business cards, and will be found among Heads of Departments, Board members and Chairmen of such companies as BMW and Siemens.

Not at Rover, though.



*almost everybody

I thought she had a second in Geography? I'm sure nobody will ever mistake her for a Prime Minister, though.

I think he may be talking about Boris.
