Charcoal heater bulkhead protection

[Moodyjim]

What should be used to protect the bulkhead behind a charcoal heater? A Hampshire Heaters one in this case.
Polished stainless steel to reflect heat but what about insulation behind it i.e. what material?
Do you need to take it up to the deck head behind the chimney as well?
Guidance appreciated chaps,
Jim

I've got a sort of asbestos board behind the SS. The stainless and the board go up to about 100mm above the top of my (Dickenson) charcoal heater. The first length of flue has a 'double skin' which goes up about 750mm. The double skin is achieved by taking a spare section of flue, cutting it lengthwise and wrapping it 3/4 around the flue, so making a sort of heat shield at the back. Do take care, it can get pretty hot. My flue has a choke damper as well as a draught control below the firebox - I have had the whole thing get very excited when I was learning how to use it and the flue was glowing.... not a good thing. And use real charcoal not briquettes which are loaded up with cement or something. They leave lots of vile ash, choke the fire, go out, are generally evil.

Hi Jim, pickie on previous thread below. I put on a stainless steel plate to deckhead - no need for anything insulating behind it but used spacers to give about a centimeter air gap behind the steel.The heater body and flue gets roasting hot but there is sufficient standoff from the heater and flue so that the bulkhead is fine - mine is white plastic panelling and does not get hot to touch.

Thanks Robin, the only thing I can find at the moment is Protec Supalux. I think 6mm should do it if I can buy a smallish sized sheet locally. I have seen 1/2 sheets on the net (1200mm) but not near me as yet.

I asked this question a while back - here's a link to the thread. - http://www.ybw.com/forums/showthread.php?333843-Backing-plate-for-a-charcoal-heater&highlight=

Thanks L/S, looks like an exploratory visit to Travers & Perkins!

I recovered a marine cooker from the boatyard skip and stripped the stainless steel side panels to put behind the home-made charcoal heater on the last boat.
The flanges gave a 10mm gap which I filled with rockwool. The flue was only 25mm diameter and I didn't bother taking the protection up to the deckhead.

We've done exactly the same, th s/s plate sits behind a Dickenson Newport which gives off much more heat than any charcoal stove I've come across and the area behind the sheet has never got hot in 8 years on use.

Well for anyone with the same problem/query I have come across Zircoflex, a .25mm thick insulation used in the motor industry as a heat shield and self adhesive if required.
Just the ticket!

If the stainless plate is thick and big enough there shouldn't be a problem with the mounting brackets providing 'air insulation' anyway.

Have you tried the Hampshire heater yet? What's the build quality like and how does it compare with a pansy?
