Barrel Stove gravity Water Heater problem

Won't work like that.....no circulation from the cold water as you have an inverted trap. You need to take water off the bottom of the heater and that connection needs to be LOWER than the coil and return to the COLD connection at the top of the heater. Install a anti-scald tempering valve on the hot disharge and a very good safety valve in the tank and the coil loop. You have a set up just like the old "range boilers" in older homes...the copper tank that stood beside the stove. Be prepared to lose a lot of water out the safety valve as you source of heat is constant and will overheat the water and produce a lot of steam.
This really isn't a safe way to heat water. I wouldn't recommend it if the barrel stove is used to heat the house. Your RUBE GOLDBERG wouldn't meet many, if any, current codes. Don't risk it.

Barrel Stove gravity Water Heater problem

I have a barrel stove that heats my house.
I clamped a 60-foot? coil of 1/2" flexible Copper tubing on the back and connected it to a water tank. With the thought that the HOT water would rise into the elevated holding tank, and the COLD water would fall down into the Copper tubing and I'd get a free hot bath.

However, when I open a faucet I get scalding hot water in an amount about equal to what I would guess the Copper coils hold, and then it turns COLD immediately.

So I assume that the water is bypassing the tank, which should have at least luke warm water in it from being in a warm area.

I'm hoping this Electric Water Heater that I'm using for a storage tank does not have a flow control device, because I'm trying to heat the tank water in reverse flow.

I put a drawing on the net at:

in case this upload doesn't take.

I always come to this Forum when one of my Rube Goldbergs malfunctions, because you sharp cookies get my gray matter to thinking. All ideas are greatly appreciated.

Happy Holidays to one and all,
