We're looking at a new house (well, 120 yr old but new to us) and trying to get ideas for some of the costs involved with the modernisation it needs.
Currently there are 2 old gas fires in the lounge and sitting room and we think we'd like to fit a woodburner in the lounge and fit a new gas fire in the sitting room.
From what I can see there is no chimney as the house used to be an isolation hospital, so...
Is it possible to vent a woodburner out through the side of the house or would we have some sort of chimney built?

Flue out the side wall and up the outside of the building. Google external stove flue for an idea of what it looks like. Needs to be certain level above roof etc - all covered by building regs.

You can get a stainless steel twinwall flue that will go out of the wall and up the gable but it will be expensive. Stove fitters may not give you the best advice on flues so the best thing you can do at this stage is make friends with your local chimney sweep, who will advise you and set it all up correctly, making provision for himself with a port for when he comes to sweep it in future years. He's counting on repeat business so has an interest in doing it right.

Edit: an old isolation hospital would have been built when coal was cheap and no consideration was given to insulation.

If you are refurbishing an old house, give strong consideration to dry-lining all the exterior walls with modern insulating materials. It will cost but will give you more freedom with electrics and will save you an absolute fortune in heating, as well as making the house quieter and generally warmer and less drafty. Also you won't need to worry about the old plaster or anybody else's crap wallpaper. At the same time I would consider pulling down all the upstairs ceilings, re-wiring for modern lighting and putting up thick Kingspan then re-boarding and skimming.

Yep, either build an external chimney (very spendy) or use twinwall either internally or externally (also spendy) - the latter is good if you like the chip-shop look 😉

The correct answer to this is 2.75 x the money you have available 🙁

If you've got the internal room to do this then it's very good advise.

This site has a quote form to fill in. I was just quoted £1100 for stove, flue and all accessories. This is for putting in a single storey extension with an internal flue up through the ceiling so probably a cheaper build to what you require.

Thanks for the tips, will look into it a bit more.
It's got a D rating on energy so seems pretty good and has been a house for about 80 years.

However you run the stove/flue you'll need to either move it away from the wall or installed 'pink' plasterboard to run it flush.

Don't use pink plasterboard, it's classed as combustible.
