I think it would work with just one tank like you suggest. Yes, the two-tank boiler is still heating for us! I keep monitoring the molybdate and PH and everything's good, water's nice and clear, no rust whatsoever.
1. Cost. I think the firebrick was already $200 -- it might have been $300 if I had done the floor in firebrick as well. 2.The insulating value -- I have 2 inches of 25 psi foam under the slab, but the sides have a much better opportunity for insulation. So I wanted the concrete slab staying as cool as possible.
The firebrick are somewhat insulating, but not nearly like lava rock / ash mixture. My test of this was to see the plastic sheeting still there after a number of firings.
Yes. In fact it is already heating the insulated portion of my workshop, an upstairs bedroom in the house, and all the domestic hot water through a heat exchanger.
I wonder how it would work out with one tank lying on its side and the stove pipe leaving out the back .is it still heating your house ?

Best outdoor build on youtube! Why lava rock instead of firebrick?

“Oh, my leg! Hank, I’m scared!”
Interesting. Will the heated water be used for radiant heating?
Yes. In fact it is already heating the insulated portion of my workshop, an upstairs bedroom in the house, and all the domestic hot water through a heat exchanger.
