stove regulations

Dublin21

Hi

can someone tell me if I get a 5 kw free standing stove do I need a full length flu (ie that reaches top of chimney) or if technically this only starts from a 6 kw up?

Also are there regulations on having a registered plate fitted? I thought this was necessary but have been told it's not. ...

any help appreciated

I don't know what you mean
Are you on about a flexi liner and if so its not completely nessasary on any flue or stove
Re regs doesn't matter if it's a 5or 6 kW they're all the same regs
If your on about a data plate it's now part of the building regs

One fitter of the stoves stated that if we get a 5 kw instead of a 6, that the flue from stove only has to go 6 inches up into the chimney with no flexible liner to the top.

I'm talking about a steel register plate that's fitted at the bottom of the chimney to stop debris falling down from the chimney?

Probably not issues at all but one supplier has told us its regulation that we have a flexi liner to the top with vermiculite poured between that and the chimney + steel register plate whereas another has said neither are necessary.

First one is wrong it doesn't matter what size the stove is it must be connected properly to chimney
What type of chimney do you have is it a clay lined chimney or brick built chimney
If it's a brick built chimney and is unlined it must be lined the easiest is by using a flexi liner back filled with vermiculite and a register plate at bottom to hold back the vermiculite.
If it's a clay lined chimney it's not nessasary to line it unless the current liners are damaged and the chimney fails a smoke test
If your house is not older than 50 years it's more than likely it's got a clay lined chimney

Is it a reg to fit a flue liner? Always thought that a stove needed a flue liner but another plumber told me this morning that I didn't need one as my house was built in 2003 and no bother with the chimney.

A chimney must be lined be that by clay liners or flexi liners there are other types.
If you existing chimney is sound no broken liners and passed a smoke test there is no need to reline it.
A chimney with the correct sized flue will work more efficiently
A flue must not be reduced in size
So basically if you have a 8in clay lined chimney and you fit a stove to it that requires 6in flue it won't be as efficient if that chimney was relined with 6in flexi flue

Thanks for that Robbie, think I'll get the liner, some price though for the liner.

What's the life expectancy of a Flexi liner?

There are 2 grades
One is 10 years the other 20 years
Providing it's cleaned twice a year only wood is used no long slumbering burns
So realistic no matter which one you use you will be lucky to get 10 years out of one

if the chimney is good, I would not bother getting a liner. I have two stoves, both working well in good chimneys, no liners needed.

I would however get a few carbon monoxide detectors.

Would it not make sense to always go with the clay liner wherever possible then??

To an extent as the clay liners will out last any steel based liner but the problem Is using an oversized flue is good either as condensation is a big problem in oversized flues and then you have the flue connection any of the clay adaptors that push into the clay liners are in breech of building regs as they're an upside down socket
