Hi everybody! Well, i have signed an agrement to buy this place. I will knock the middle wall between the two doors on the left. And redo the top floor lower. That will be a wooden floor. And here i run into a problem. What do i stuff under the bench? Well, i know that i want a batch rocket, with a fireplace look. I have fireplace stones, mantelpiece etc. I can raise the firebox, and have airspace below the base stones. But i'd rather have a low bench bell besides it. I have refractory slabs which are 10cm thick, 50cm x 50cm. Plenty of firebricks I can stuff two posts under my stove to support the joists. I know a bell bottom doesn't get that hot. But i'd rather be safe than sorry. Do i make a cutout, like for stairs, and put rolled steel joists in there? Do i pour concrete on the RSJs ? This stove will have it's back against a north facing Optibric wall. I was thinking drywall and perlite or vermiculite behind. Or do i go for a segment of firebrick wall and vermiculite behind? Would be good if you help me think.

Off topic, love the wall of windows. Stunning place you have there. Best wishes! Well, there's four windows, and four fake ones! No concrete slab on the bottom, a wrecked wall where Fabien, the neighbor crashed in at startup with his 26 tonner. No electricity yet. Just sewage and water. No doors! I had found the doors secondhand, ready made, but haggling and bartering with the guy took soo long that they're long gone!

I'm daft, i didn't think, air entrained concrete over a osb layer, on the joists, that should be all right!
Whatcha think?

Congrats, Satamax! Man, that's a project all over the place. From my experience as a carpenter turned transformer test technician, I say add a little beef under the bench system... Better safe than sorry! You would probably be a little dismayed when your warm tush ends up in the basement! I like the air entrained concrete idea- never worked with the stuff, how much difference per given volume versus other material? Wish I could fly to France and help ya, I love undertakings of house refurbing sort! Cant wait to see the progress! Eric VW

I would leave air space so you can get your hand under there and monitor what's going on. I always recommend that on wood floor, otherwise you are just guessing how much heat is transferring down there. I know that in normal use, the underside of my mass is fairly cool, but when it's really cold out I can run that thing wide open for a long time, and there is a huge difference in temps. I'd hate to be wondering how hot it was getting on the wood, and it varies so much throughout the build I wouldn't trust embedded thermometers to give a good idea of what's happening everywhere. There are still ways to get appropriate seating height, whether it's raising the humans(low platform around the seating area) or just building the mass fairly shallow and extending it further.
Remember that tightly coupled masonry, even insulated, will transfer heat. The insulation just changes the time it takes, but not necessarily the temperatures unless there is some air space or the like to move the heat out of that area. I've seen the outside of insulated masonry that is normally cool to the touch become amazingly hot after long periods of constant burning.
Nice place Max, congrats!

Max, So this is your new place. Looks good, is there much work to be done?

Max, So this is your new place. Looks good, is there much work to be done? Well, the banker hasn't said yes for sure yet. And yes, there's tons of stuff to be done. But the two chimneys are ready When the doors are on, and the slab is poured, i can stuff the green machine in there straight away. With a second bell, or mass, i'll see what i do. And i'm starting to think about top floor's heating.
