    I wish you well with this, I've wonder if it was possible too ...but how do you by-pass the water when it's up to temp...? Also is that duck work for your stove pipe?

    Do you have a circulator somewhere? Is that a buffer tank or your main tank? Are both elements off?

    No pump,thermo siphon. No shut off I just close the damper. No duct work.
    I have been running like this over two yrs with no trouble, simply works.
    This is the main tank,60 gallon tempering tank is in the works.

    The coil is from hillcoil New York .
    It is schedule 40 stainless and suitable for domestic water.

    Is there a small expansion tank in line some where. Do those two uprights with valves have captive air for expansion? Thanks for posting this.

    I guess you drain the solar panels in winter? Or is that a closed system with Antifreeze?

    Looks good, glad it works for you. Nice to get a system like that done instead of just thinking about it. Good for you.

    Solar is a drain back system, it uses water. When the panels reach temp a controller starts a pump and fills the panels and when temp goes down pump stops and water gravity feed back into a 15 gallon drain back tank. The d.b.t. Has a heat exchange coil connected to the 120gal. Domestic h.w.t. Solar panel water and domestic water never mix.

    That is nice. My grandfather had a similar setup through a coal stove in his basement.

    I'm really interested in this thread. It's a good ,simple , low cost approach. I've been thinking of a similar setup adding a radiator loop directly above the stove to heat the bedrooms. I'm also thinking that a HPWH in the basement or somewhere in the loop would enhance it.

    Yes it's an interesting approach to heating water...it's something I know I have thought about but never got around to doing. It also goes to show that you don't have to break the bank like many of our systems do..

    Nice work !
    I'm in the process of scrounging together cheap/free parts/fittings/pipe for a tempering tank set behind the furnace with a short coil looped on the front around the door.

    Nice. Many houses in the UK and Ireland, including the house I grew up in, have these built into an open fireplace for hot water and/or radiator heating, where they are called "back boilers" or "fireback boilers". Due to the obvious dangers, there are strict requirements which must be met.

    As to the obvious dangers, what safety/convenience features would be needed for this? Mixing valve, Pressure relief valve, Air purge, ex. tank, shutoffs etc.

    Tempering tank is half the battle. Bring that 45 degree water up to 75 degrees means a lot.

    I'm thinking with a coil even on the outside of the door I'll achieve 100+.
    Really want to ad a passive solar earth berm room to the south side of the house this year but don't know what finances will be like. Plan on water storage/heat sink, green house,built in root cellar, and a modified oil furnace that I can run off an endless supply of veggie oil from a restaurant the lil woman manages. With the propane situation lately I'd like to have another source of heat.
