Used to have a permenant camp-site where we put them in the bottom of the fire pit, then up-ended concrete blocks around them, all sunk into the ground so the edge of the blocks were 3" to 4" above ground level.

I have a load I'm keeping aside for a fixed camp when I hopefully buy a bit of land next Spring. They make great fire surrounds, I used to have a couple I used that way years ago. I had a side of the fire pit made from them for putting the coffee pot on, tin cans that needed heating and I'd sometimes brush the dust and ash off and cook bacon and sausages straight on top of them.

Dumb question, but was their function in the heater to act as thermal mass to store heat, or as insulation? I can't believe that a normal storage heater would produce temperatures high enough to require fire brick insulation. Also, there are many kinds of "fire brick". Some are very light and full of air, like mineral polystyrene, and are used for high temperature forge liners. Others are a little stronger but less insulative, and still others have almost no real insulation properties, but can take the temperature, these last feel heavy enough to be bricks.

Are they any good for an outdoor brick barbie base.

The first time I came across the idea was about 30 years ago and they were in the bottom of a huge BBQ pit, probably 8ft X 4ft, took two days to get it up to temperature with a good bed of embers, took longer to cool down though :rolleyes:

They tend to be pretty fragile, not like an ordinary brick.

It has been very cold over the last few months and I work in a large cold workshop. If your feet get to cold then work suffers. I put a couple on top of the wood burner and when needed I take them off and stand on them, lovely toasty feet, and a happier working day. When left on the floor they do retain there heat for a good time. A couple of fire bricks have hugely added to my quality of life
