Using 10m of Vitreous enamel flue pipe???

Skulls

This may be a stupid question to those in the know, but , I'm not! I installed a Villager stove about 5 years ago into an Inglenook type fireplace. The fire is connected to the register plate with a 1m long flue pipe. The chimney is roughly 10m long and is not lined. As the open fire used to draw well I thought this would be OK. It's been great so far in all sorts of weather.

My question is, as the top of the chimney is straight up roughly 10m would I have more control/better output by using 10 x 1m flue pipe all connected to the top of the chimney. By connecting them with heat sealant I could regularly take the pipes out and sweep them myself.The chimney pot is a H type pot that works in all sort of winds and doesn't let any water down.

All thoughts most welcome, cost of 10m of flue pipe £190.

If it ain't broke, why fix it? If you are sure your flue is fine, why bother lining it? Nothing in the regs to say you have to have a lined flue.

Just thinking if I only heat a 6" pipe instead of a 2' x 6' chimney, it's that size for the first 6-7m, it would be more efficient.
Forgot to say thanks for your reply!

Are you having problems with the chimney though? If you have a good draw, efficiency doesn't come into it. I wouldn't recommend using separate sections as there is too much potential for a leak. With the pot blocked off from the remainder of the flue, you are looking at making a death trap if it leaks.

Either use the proper materials (twin wall flue pipe, preferably 904) or stick with what you got would be my advice

You could get 10m of 316/316 liner for £190!

With the 1m sections I can install from the bottom, the retainer plate is about 1.3 m high. And it would be easy to take down say twice a year to sweep.

I don't see why you would want to take it all down to sweep it? Chimney sweeps don't pull liners out to sweep them!

You are going to have to replace the pot anyhow so what difference does it make if you install from below or above? The mess you would generate would be huge if you took it out, very dusty.
