We've got a good (free) source of wood, and a largish house that is heated by electricity.

We have an open fireplace and an efficient chimney but, or course, most of the heat produced goes straight up the chimney.

We are considering getting a wood burning stove and bringing out from the fireplace, so that the convection heat will stay in the room.

I've drawn a diagram of what I have in mind, would this work (naturally I would take precautions to avoid setting the house on fire

Be interested to know the PH collective wisdom on this one, as it's a potential option for me too...

This is how a huge number of wood burners are installed. You don't gain a massive amount in efficiency by moving it out into the room though because modern wood burners have very carefully managed air flows to channel heat to where it's needed.

Buy a Clearview stove!

Put it in the fireplace and it will warm a large area. You wont have to block the fireplace but you will have to get the chimney lined if it isn't already.

wot e said.

Makes little difference to the efficiency and it won't actually lose as much up the chimney as the exit from the stove is often sealed to the stack opening by means of an adapter.

What do you mean exactly about the chimney being lined (couldn't find anything on that site about it)?

You make have to look at putting a liner up the chimney, seeing how you would be burning class 1 fuels.
Idea is fine though.

I guess that as I've used wood and coal stoves for 25 years+ I may have learnt a few lessons, I shall pass them on.
1. The stove in front of fireplace is unnessasary, it will cause more problems for flu extraction.
2. Keep the stove within the fireplace and keep the flu as straight as possible.
3. Two types of stove are available and the choice is yours :
Secondary burn stoves are by far the most effiecient and in terms of output and combustion.Must burn with closed doors and much more expensive to buy than open stoves.
'Open stoves' are far cheaper to purchase, you can burn them with doors open for nice effect.
4. Look carefully at the KW output of the stove and only buy a stove that is NOT larger output than you need for your room size.
5. Only burn good dry seasoned wood, if you burn 'wet' wood you will end up with problems.

Any specific questions I will be happy to answer. There are loads more factors to be considered.

Yep and then they fill the space outside the liner with stuff that looks like vermiculite.

My house is 1930s and the chimney is old so its the easiest way to stop the potential of a chimney fire.

My Clearview warms the whole of the ground floor.

Just to clarify on the Stove front. I have one of these Its a highly efficient stove when its properly lit it actually burns most of its own waste gasses and has internal convection past the window so that the window stays clean. Occasionally it may get a bit sooty when starting the fire but its self cleaning. Also its big enough to cook a stew on the top in the winter when you run it all day.

FWIW I'm looking at getting something like this: http://www.firesonline.co.uk/acatalog/Aarrow-Strat... which actually sits in (and fills) a standard modern fireplace.

I wasn't aware that you couldn't run secondary burn stoves with the door open though. What's the reason for this?

You can, as suggested use vermiculite, but I would'nt. Instead have the flue liner wrapped in an insulation blanket. The problem with vermiculite is that when the time comes to repair the liner or baffle plate you will end up with half a room full of vermiculite balls, and they will be filthy.

My experience with that stuff is that it rots faster than a 1958 Morris Minor. Isn't there a better option? Is the idea to restrict the bore of the chimney?

I would replace the 'board' with something heatproof, but otherwise I don't see a problem.

However, if your house does burn down, please note that I'm totally unqualified to comment and this advice is at your own risk smile

I believe the idea is to stop you dying from carbon monoxide poisoning.

That's why you used decent quality stainless steel stuff, cost a bit more but once you've fitted it you can pretty much forget about it.

But how does it do that?

TBH if you can find a decent installer then you should be able to find out all the options from them for this kind of installation.

Mine has been going fine for 10 years now.

I have been lead to believe that you could get some kind of gas soak through the chimney unless it was properly sealed and that the easiest way to seal it was with a liner. I might be completely wrong though, I'm far from an expert.
