Can't make out the pictures too well..... Is that a 55 gallon drum? Might I add that water volume is not a definition of heating capacity nor is square footage. I heated my 3500 square foot shop last winter with a small gasifier that only held 30 gallons, but required approximately 84,000 btu/hr to maintain 65 degrees with a temperature differential of 50 degrees. Not all that healthy but 16' ceilings take their toll....
My point is that the water is as much of a heat transfer medium as it is storage. If you circulate water continuously and have a healthy enough fire you could heat a very very large area with that. Your only set back potentially is surface area to transfer heat to the water. Maybe I'm looking at this wrong as I cannot make out very well from the pics, but if I am seeing what I think I am, it could work very well as long as every other factor not related to the burner is ideal to the conditions of operation.
