Hello All,

 I'm thinking of upgrading my outside woodburning water heater.

 I am wondering if it would be better to heat the water in a 5gal. tank or
use 60' of 1/4in copper tubing running back and forth.
Either the tank or the tubing would be in a chamber above the burning wood.

 Anybody have knowledge/experience in this area?

Thanks
Ray

I have no knowledge on it but i would say tubing would be best.

How about brazing sections of 1" tubing (vertically) through the tank
so that the hot gasses pass through and around the 5 gallon tank?

 I've thought about a design similar to that. It would be a larger scale.
 Something on the order of a 25gal drum inside a fuel oil tank. Lots of
welding.
It may be my next upgrade. I've gotta gather materials first.
It is a deffinate good idea. It would double my storage and less fire
stoking.

 More surface area = more heat exchange
