Producing hot running water

[kawalekm]

I thinking about different schemes for producing my own hot running water. Our cabin is in a sunny southern exposure, so I want to try a solar batch collector first. I'll try the recycled water heater tank idea. I realize though that this will only produce hot water in the summer months and needs draining come winter.

I just bought an old Monarch wood cookstove and am thinking about producing hot water with it. It has a hot water reservoir on the right side, and am wondering about adapting it to making hot RUNNING water. What I envision is running a coil of copper tubing inside the reservoir to absorb heat from the hot water.

My first question is how hot does the reservoir water actually get? Can I expect 120F or 210F water. How long does it take to get hot? If hot, how many feet of copper tubing will I need to absorb the heat?

A second idea is instead to wrap copper tubing around the stovepipe exhausting the stove. I'm worried though that this might be potentially dangerous if the water boils inside the tubing. It could cause an explosion. Is this a realistic concern or is it not something to worry about? Again, how many feet of tubing do you need to absorb enough heat for a hot shower? I have not plumbed the cabin for running water yet so I am free to run pipes wherever I chose.

I have done this with the copper tubing. Remember though the water needs to be running or the water will come to a boil causing steam , causing pressure. Also it makes a difference how fast the water is moving through the tubing and how much tubing you have and how far away the tubing is from the heat source and how hot is your heat source? Quite simple really , you just have to experiment.
