Newbie here got a question

Redneck water heater mod

Water expands as it's heated, so you have to have some type of pressure relief device.

I'm not sure that it would heat that fast. but I am very interested to see it work.

I just throw a pot of water & a kettle on the firebox.

No pressure tank needed...

Just make sure you place the valve before the firebox. That way, any residual water in the heating coil will just drain out as it expands.

A friend of mine vended two and three days days a week for several years with a system like this. The outlet of the pump was tee'd off, one side went straight to the faucet, the other side ran through a coil of copper line inside the cook chamber. It worked well and he never had the pipe burst. Not to say that it wouldn't happen, but it didnt in all the time that he used it. Gotta remember though.. that water is about twice as hot as the hot water at your house and it will hurt you bad.

There are advantages and disadvantages to the set-up but overall it was a good functioning system. Like puppyboy, I personally keep a kettle of water on the firebox and it provides just fine for my needs.
