Fitting a log burner ?

[Alycidon]

if you can build a chimney breast in the room, i have it is only 11'' in to the room, and it is on an internal wall, after about 1 hour, you go a feel the wall the other side the wall is nearly to hot to touch. so if it goes out side think of the heat lost.

 

check the planning portal

 

Big job that and it limits where you can place the stove, twin wall allows you to place the stove where you want.

Another vote here for going strait up through the roof. Our flue is of this type and it was very straight forward to do.

Normally you will have a ventilated plate on the top side and a magnetic ceiling plate on the bottom side. Mag plates are sold to the trade by Specflue. They are a Poujoulat product but I cant find them on their web site. If you have used Poujoulat product then they will be fine but if you have used something else you may be limited as pipe diameters are different between brands. Poujoulat is expensive but it is the best.

Thanks!

mine is straight up thru the roof as well, took the old chimney down and made the kitchen / living room open plan with a 2 sided stove

Well you could use 45 deg but not 90 deg, you can only have 150mm of horizintal pipe in the whole system and a maximum of 33% of the whole flu length less than vertical. Remember you will need access to the chimney you would run into to allow sweeping and soot removal, the pipe from the stove is swept from inside the stove usually. To penetrate the ceiling you will need to use twin wall insulated pipe such as Poujoulat TI.

 

The best idea is to go straight through the lounge ceiling then straight on up through the roof with twin wall pipe all the way. This is something we do almost every day. The pipe can be powder coated to match the stove and a white magnetic ceiling plate makes the lounge ceiling look nice and neat. In the loft a spring guard is fixed to the pipe to prevent combustibles falling against the pipe. A large lead slate is used on the roof assuming its tiles or slate.

 

Dont forget that the installation needs to conform to Approved Document J of the building regs and needs signing off as safe to use by a competent person. This can be a Hetas registered engineer or a building inspector if you install it yourself. Failure to get it signed off will invalidate your property insurance if you ever have a fire and you will then also be prosecuted for breech of building regs, fine is about 4.5k.

 

App Doc J can be downloaded from the Planning Portal website for free.

 

Flue exits, if within 600mm of the ridge then 600mm above the ridge minimum, elsewhere on the roof no less that 2.3m horizontally from the top surface of the roof tiles.

Thanks everyone

 

Alycidon. Thanks for the advice. The 33% of the flue being less than vertical as scuppered my plans!

 

The bit i cant get me head around is the flue exists. My burner would be on an external wall so the flue would exit close to the rear of the guttering.

 

How far would it stick out of the roof ?

 

TIA.

 

Oh and i will be getting in a Hetas firm into install it.

I get the flue exits now:blushing:

 

Depends on the pitch of the roof as to how far the flue sticks out..... I got there in the end:sneaky2:

Use Poujoulat TI pipe, its combustible clearance is half that of most of the other brands. They also have adjustable wall mounting arms (200mm - 400mm is the most popular one) so the pipe can be off the wall by some way. We also use them on teh outside to save having to have two expensive bends going round gutters. We come off the wall and go straight up, cheaper and with no bends the flue works better. Dont forget the powdercoating option, make sure your supplier can do it, if not most local powder coaters should be able to do it.
