yes, that is the obvious answer, why is it piped this way, whats with the circulator? do you usually see storage tanks piped this way?

BINGO, it will be for radiant, the hot water is being fed from a wood burning furnace. instead of a flat plate heat exchanger, we are using this tank for heat transfer. we had some questions regarding btu,s, and recovery, but we are confident this will work. G

Have seen it done once before as a temporary fix till the boiler came in. Worked like a charm. have you tested it yet

Tommorow, we light it up, electrician coming at 11. the wood furnace requires 3 small warm up fires over 2 hrs, to allow the firebox to get up to temp without cracking.

We did not get fired up today for several reasons, the most interesting thing we learned today while building the system, i will share, maybe someone will be sparred this time consuming mistake. The wood burning furnace has a damper that is tied into an aquastat and a pressure switch. The damper is supposed to open as soon as power is supplied to the unit, this opening supplies the air, to start the fire. We plugged in, the damper failed to open, we jumped the damper motor directly, it opened. So after a couple of hours of trouble shooting, we finally reached the company. Here is the deal, we opted to use a water storage tank, instead of a flat plate heat exchanger, the water storage tank was in the basement, just below the wood furnace, now when you add the lenth of the coil, in the storage tank, plus the fact that it was 8ft below, the supplied pump did not have enough pressure to push down, through the coil, and back up again, by that time the presure had dropped so low, the pressure switch would not activate----The solution, A LARGER MORE POWERFUL PUMP, we will install the new pump tomorrow, and hopefully, start making heat, Gene

Just a couple of question G...why is the copper plumbing tied into the blk. iron fittings? Why isn't the water heater raised 18" off of the floor? No drain pan? NO check valves installed into the system? Where's the p/r valve? Pipe insulation around the copper (type L) of course. Inquiring minds want to know.

Please be more specific, my plumber needs more detail on your questions, as far as the 18" off the ground, never done around here, we just build up on cement blocks, in case of mi or flooding. This is a 60 gall SS tank, no drain pan required. Pipe insulation will be installed, we are not done yet. He has been joining copper to blk iron for 29 years, so did his father, so we are not sure what your concerns are. Give us more detail, and we will happily respond, Regards Gene.

G-While I do respect your answers to my questions I also question the longevity of the copper connected to the black iron fittings bring corrosive issues in the future. I've never connected the to different materials together for water supply lines. Going back and looking at the picture I think that I see the spring check valve installed between the blk. iron and copper just above the 3/4" elbow.

I install brass nipples/fittings when making any connections between copper(more expensive) of course. Where's James,Ron the plumber,toilet killer with their more knowledgeable experience.

Galvanic corrosion

Electrolysis can and will occur unless a dielectric union is used or a brass nipple...tee....90....Brass needs to be inbetween the copper and steel. I have seen black pipe used sucessfully like that in oil systems. I would never do that with potable water. That said on verticle runs it won't be an issue for many years, for horizontal pipe it is a service call in the making.

Well I used a PEX male threaded adaptor as far as i know it is brass.

EDIT

Nevermind I understaind now. Thanks

One more thing what if it is a gas water heater will electro-galvanic still happen?

WarnerConstInc.

Its not for drinking water, who drinks hot water anyways.

Nobody that's ever drained a hot water tank.
