Heat proof material

[Tubbster]

I have a small Masport Yukon pot belly in my shed, that I installed soon after I poured the cement floor, as we were in the middle of winter.
However since then, over summer i have been lining my shed with sarking, fat batts & MDF sheeting, which I have polyurethaned, then painted, comes up a treat, but when I installed the pot belly to maximise space I had it against the wall, flue is probably about 100mm from the MDF, and the main body of the heater, about 200mm.
What would be the best material to place behind the pot belly, and would I have to run in all the way up to the roof, following the flue, or just behind the heater body?

I would say you must seek professional advice for this, you need some warranted advise and product. When I lived in Japan about 12 years ago, there was a spate of unexplained house fires that were eventually tracked down to carbonization (charcoal formation) of wood behind stoves and heaters. Charcoal has a much lower ignition temperature than wood, once the wood converts to charcoal, it'll eventually catch fire.
scared you enough?

you used to be able to get heat proof fibro cement sheeting we put it above the gass watter heater under our house to stop teh heat burning teh floor.

Thanks to both of you, will do some more research on this

Another way is to create a baffle set off the MDF. Get some aluminium sheet and some aluminium tube and cut the tube into 25mm lengths and get some screws long enough to screw into the MDF and go through the aluminum sheet and the tubes and set the sheet off the wall to create an air gap between the MDF and the aluminium sheet.


Allow the sheet to extend about 200mm past the edge of the heater and run it up behind the flue extending about 100mm each side of the edge of the flue.


This is how I used to protect roof timbers when installing heaters.

Thanks, but have decided on using Hebel blocks, as they are heatproof, and are the perfect size, 600mmW x 200mmH x 75mmD and only $4.90 each, the Flamechek plasterboard I have been told by hardware store is fire proof, not heat proof.
