Installing a wood burner..

[Chillitt]

Recently I got a woodburner and now its cooling down a bit I'm thinking it ought to be installed..
I've got an oil fired boiler in at the moment but its ugly, noisy and oil is expensive.. I've take what may or may not constitute a sealing plate out to have a look up the chimney, and a couple of foot up there is a 5" flexi pipe. The wood burner has a 6" flue. Is it ok to reduce it it? I'm sure there will be more questions, but best to start with the basics.
Oh and BTW I'm skint so replacing the liner is a bit of a non starter at the moment

have you got a photo ?

have you tested the chimney ?

oil burners are one thing wood burners are another

oil burners not much heat output
wood burners can be high heat output
rocket stoves low heat output

oh and skint makes no difference to your life

Out of interest how old is your house?

We had a new wood burner 2 years ago and for building control it needs a 6" flu as far as I know. There's minimum dimensions for the hearth as well.
You can't really install a device that creates carbon monoxide on the cheap to be honest, it has to vent properly. Also a restricted chimney won't give you the draw a fire needs.

OK, found a manual for the stove (AArow Stratford TF90) and its a minimum of 6" flue so I need another plan. The house is 1840 something.

Its an old original fireplace about 4 foot wide, not an outside wall, the forge is on the other side(with a different chimney). I'm in preservation area so no chance of putting an external flue in anyway

Needs to be installed by a HETAS registered engineer, pretty strict rules now and it it goes wrong your insurance will be voided

Also CO is a very real danger with wood burners

Or via planning. Luckily I had building working going on when I fitted the stove, paid £25 for the amendment to show the stove, so building control wood pass it. I knew more than the building inspector regarding part J

Anyone can install them, and get them signed off by building control.

It's one or the other though - hetas or BC.

As for the flue -

Document J states 6 inches or the size of the appliance outlet, whichever is *larger*.

Hetas installed my brother's burner with a 5" flue as they couldn't get a 6" down the stack. As to if they should have done that, who knows.

I found the same when they signed off ours. Which surprised me, as doc J is very "black and white" - it's just measurements and sizing, very little interpretation or grey area.

Another note on flues -

Wood burners need more involved flues than, I believe, oil stoves do.

Simply sticking a wood burning stove on the end of an oil Flexi probably isn't the best plan.

I've not looked but a stainless flue kit with cowl, appliance adapter, etc. is probably still under £200 unless you're stack is unusually tall.

Am I the only fool that would pull out the liner, have the chimney swept,fit a decent register plate, fit the wood burner and enjoy it How the hell did we ever survive for all these centuries without a stainless steel flue liner? Not condoning the use of a knackered chimney but surely only a tiny fraction of them are unfit for purpose.

They are though, when used with gas appliances it rots the mortar, I've seen a few collapse when doing alterations

I have always had wood burners and never had the need to fit a liner, if the chimney stack is rotten to the point it will leak smoke surely the stack would collapse. I noticed someone on here with clay pots and a liner, surely thats overkill.

its not that bob its shared chimneys that are the issue if the mortar is bad between the chimneys the ocupants can be gassed and killed due to poor matenence of the chimney

a liner is used from the appliance weather its a gas oil or wood stove the liner does its job

clay pots with wood stove is a no no they are known to shater due to the heat going through them its alos the same for these no concrete small liners you see alot of times in new builds tehre just no good for old wood stove usage
