I've heard willieG mention his domestic coil setup more than once before and I haven't seen it yet.  I got him to email me the pictures and I'll post his pictures and description for all to see with his permission.  I really like the idea and if I can source a big pipe like that, I'll build one myself.

It might just be me, but it also looks a lot like part of a distillery.  Maybe it serves double purpose during the warm months.

This tank is 12 inch pipe 22 inches tall with a 50 foot coil of copper inside. I believe the OWB water is moving at about 6 gpm and the return temps I am not sure but I know you cant hang on to the return pipe or the domestic leaving the coil
 
When I made my first one I was not sure if the coil would be long enough but it is
 
If you have any more questions feel free to ask


Photo of the coil wound over an 8 inch pipe (this springs back out to about 10 inches)



Me putting in a lid from a 5 gallon plastic pail…I used a ceramic tile on my first build but this was all I had on hand, I like to put something in the bottom to keep the copper coil from coming in contact with the carbon steel



Coil  connection ¾ male thread to ¾ sweat insert this into the ¾ coupling welded to the pipe bring out the end of the coil, now for the next fitting ¾ female sweat to ½ femal sweat….before you can put this over the coil you need to remove the stop inside the fitting that keeps your normal ½ inch pipe from sliding in too far…after you have done this you can slide the fitting over the ½ coil and onto the ¾ male..now just solder both these connections and your coil is now separated from the tank water. Do this at both the inlet and outlet for the coil. As for the OWB water just put in the ¾ male thread to ¾ sweat and away you go.



Coil inserted in pipe and plastic lid can be seen below it




All done

Well done Willie, necessity is the mother of all invention, I bet you never run out of hot water as long as you don't forget to fill the boiler do you?

Exactly Slim. When I first hooked this thing up I made it as "On Demand" and bypassed the hot water tank and had the power to it shut off. BUT, as you said "as long as you don't forget to put wood in the boiler"
Back when I built the original  for my own house I was 15 years younger and still had some partying to do. There was a time or two that I slept in and woke up to a boiler only running at about 110 degrees, house was still warm but the shower water temp didn't go over well, and with a headache the flack I got was more than a man could handle. So, now  my hot water tank is still turned on and the tank I made feeds into the cold water supply of the hot water tank....just in case I start to relive my childhood

[slimjim]

I may be taking another road trip in a month or so and possibly through your neck of the woods, I sure would like to stop by and help you relive that childhood.

[willieG]

any time you venture into this neck of the woods you are welcome to stop in for a refresher or two

Let me know when that happens! Willie is only 2 hours from me, and he and I have hooked up a few times already and went to the farm show in London Ontario.
I'll buy you both a cheap steak and a warm beer!
