I've often steered clear of the subject of heating water with a Rocket Stove. It's a dangerous proposition, easy to get wrong and potentially deadly. Here's an exception to all that. This guy's thought it out and provided an easy to replicate design that is safe, efficient, and can be built with simple materials. |

I've always thought about making a small one working the same way as the instantaneous gas water heaters where you have a large burner below a spiral of stainless water pipe - cold water in the bottom and instant hot water out the top. I have a calor gas one I use to heat the water for my shower and it says max 15Kw gas input, 12Kw hot water output on the side. You could even wrap the spiral of pipe around the inside of the top of the barrel over your heat riser. |

I have a similar system at my farm , the heating input is wet back slow combustion though. Same principals used just the heat input is external to the tank and 5 m away . It has a electric pump for circulation to tank but when I set the system up I aimed for convection flow to be enough to maintain correct flow. (it does this with the "impeller pump" off quite happly) The only effect of the pump off is the tank takes slightly longer to heat.
The whole system provides hot water for showers and a hydronic floor heating for 200 sqm of mud brick house in victoria Aus
The main tank water level is maintained by a header tank on the over flow pipe , with a float valve.

Separating the tubes from the fire by a non pressurized volume
is a simple and quite foolproof method to prevent steam explosions.
I had mentioned that before.
Could be improved by means of a trap in the overflow
to minimize loss of water by vaporization.
