[Stoves] Heating water

[Alex English]

Another inverted way of heating water is to pass the hot  gasses through 
a pipe that goes in and out a tank. I have used 3 inch muffler pipe bent 
with two 90 degree bends to go in and out from the top of  a  tub to 
heat water for washing wool. We fired it with a propane tiger torch but 
it could be done with other fuels. We are currently working on heating 
warm water in a 24 feet diameter X 3 feet deep  tank/pool made with 
polyethylene and old conveyor belting. This would be fired with chips in 
a Quasi Dasifier but a TLUD could work.

These would of course be  partial condensing heat exchangers with 
potential corrosion issues inside and out, but we are using schedule 10 
sprinkler pipe and the cost is low in boiler terms.

Just another way to look at the problem.
