I built an oven with a 48" diameter and it doesn't seem to hold heat very well. It takes forever to get up to temperature, less so now that summer is here. Initially I thought it was a crack in the dome, perhaps it still is but regardless, I don't think the oven floor gets hot enough. It seems the oven is mostly top heat. I can cook pizza in 4 minutes or so, but don't like the lack of bottom heat. I am thinking about removing the fire bricks and some of the vermiculite layer beneath and putting in a couple of burners and connecting them to a propane take. I will vent the area and figure out a way to light them. But my idea is to put the pipes in and then pour a floor made out of refractory concrete. The whole thing will be tricky as I gave to get the bricks out, enough of the vermiculite/cement insulation layer to lay some burners in, then get the poured concrete slabs (2 slabs) through the oven door. I plan to set them right on the fire bricks that I will leave around the edges. I still plan on building a fire, just want the additional bottom heat. Am I crazy for attempting this? I just find the current oven very inefficient. Any advise would be helpful.
No announcement yet.
