New OWB

Well, been a while. I figured the volume of the big pipe and subtracted the volume of the small pipe...didn't worry about the wall thickness! 100g and I'm sticking to it.

I guess you'll have to make your hot water inside the house. You can buy a tank with a coil inside, but they are expensive. You could wrap a regular heater with some tubing and reinsulate, or, of course, use a heat exchanger outside a regular tank. You can do a thermosyphon for the tank side, but will have to pump the boiler loop through the coil.

Sounds like fun.

I already have a loop heat exchanger in the house. But it is set up backwards.My water heater is fuel oil fired. It is my back up heat for the house.
I did not build this boiler to save much money. My average fuel bills per month is only 125 in the coldest of months. I did it to prove to the oil company. That I do not need to rely on them.
Domestic water is not a big concern. as I want my water heater being used and cycled.
I am sick and tired of this hot weather.

Be careful of what you wish for. Must be like having a snowmobile and no snow?

I added more photos.

It is fired up and coasting. Not that I need the heat. I just wanted to test fire it before cold weather set in. Only one more control to hook up. That is a temp sensor, that reads the temp in the storage tank and will switch the blower on when the tank temps drop below a set point.
