Re: Park Oven Progress

You always have the open area underneath to fill with insulation..

Re: Park Oven Progress

I personally would tear down the partially built dome and install proper insulation between the slab and the oven floor. There's no telling how the oven might perform simply by insulating under the slab. Heat will still bleed off the edges of the slab and into the cinder blocks on all sides. The oven floor must be completely isolated from the concrete slab for optimal performance.
I'm sorry to see this happen on an otherwise fine looking build.

Re: Park Oven Progress

Another possibility might be to pull up the floor bricks, put down 2" of insulating board, then reinstall the floor.

Since the entry and dome are not yet complete, the design could be modified to accommodate the elevated floor.

It wouldn't be a perfect solution, but should be better than putting insulation under the hearth slab.

That, I think might be the easiest fix, leaving only the bottoms of the dome wall uninsulated. But I think heat loss around that entire perimeter could still be significant.

Re: Park Oven Progress

Concrete bricks/blocks and heat dont mix, Ive clocked my flue gasses at 600 degrees c.

Re: Park Oven Progress

appreciate the advice...
will do something else with the chimney .... (was going to go ahead with cementing them there)
had the besser blocks just sitting loosely to get a visiual as to what it may look like ...
still have clay oven bricks left over... will build with them or get a clay pipe.
will concentrate on front arch for the moment...

Re: Park Oven Progress

arch done .... thinking about chimney now... then front facade and side walls

Re: Park Oven Progress

How are you going to retain the heat in the oven as it will just go out the flue?

You could do a damper in the flue as I did, its just a piece kiln shelving that just slips into a slot in the brick flue.

Re: Park Oven Progress

That's a very clean looking build so far.
But I'm still concerned about how you're going to address the lack of insulation beneath the hearth.
