Underfloor heating, any plumbers?

yup will kill it dead. Seems strange I know when it has a 6" hole in the top but it does work

Get the fire cement out and chase the joints, you might be surprised

a 1/16th gap to keep the thing over night and 3/8th to have it roaring.
Thats how fine the control is. Tiny leaks make a massive difference

got to agree with Skeetly there, the air control on mine is thermostatic, but the amount of movement on a 2" disc is 5mm from fully open to fully closed. if not properly sealed the fire never 'slumbers'.

Ours will not, with the door shut and the draught "fully closed" it still roars like mad.

I don't think the ash box is actually sealed onto the base of the stove. Bloody folks buying cheap shoite. "I warned ye!"

Big leak somewhere then. You should be able to find it if you get it roaring...

Relatively speaking that is, could be quite a small opening or lots of them.........

Does the fire 'roar' with only coal on it even with everything closed? If it does then that suggests a leak underneath as coal fires need air from below to burn well.

[yorkie_chris]

Roars with anything on it if you close the door.

I think it is the tray underneath for the ash box as well as the flap at the back which is supposed to close the airflow off.

[Luckypants]

definitely has a leak below. I'll demonstrate on mine the effect of leaving the ash pan door open, it will kettle within a few minutes and I have no doubt there would be explosive steam after 10 or 20 minutes.

You will have to control the rate of burn before fitting a boiler.

What dry lining did you use and what steps did you take to remove the draughts?

Cottage got gutted when I bought it. New wooden windows and doors with proper compressible seals. New floors (gutted I didn't put ufh in them )
Originally I left the walls unlined but stone walls have the same insulating value as an inch of polystyrene so Ilined them with insulated plasterboard and it's been much better New extension each end helped as well....
You need to make sure that your walls aren't damp and that you have a vapour barrier to stop any moisture withing the house condensing on the walls behind the boards or you will have hassle.
Easy. For a builder.......
