Beer, not rocket chemistry
Some of us have been discussing a stand alone flash boiler. kind of a homemade hot water on demand unit.
I used a design I got from kladue that used four seperate coils joined through a manifold. Johnbeer has been talking about this as well. My problem has been getting the thing to stop leaking. I have not given up, but I decided to tak anothe course and see what happened.
I took a 50' coil of 3/8" copper I had for a chiller and roller it into a coned coil I installed this inside an old cornie with the bottom cut out. I ran an inlet and outlet through the cornie wall and bracketed the whole beast over a high BTU burner.
I pumped water from one of my kettles through the heater. The water began at 58 degrees. Running at about 2 GPM with the burner moderately high it raised up to 178 degrees in one pass.
This worked great and really used a whole lot less propane then heating the whole kettle at one time. It also means I can reduce my brewing schedule significantly, utilize my second kettle as a heated mash/lauter tun.
I want to play with some other configurations and need to address venting the burner as it exits the heater.
I will be keeping track of this project in the new Gadget Junkie group. Come check it out and add your own projects.
