Nice!
We've got 176° hot water coming out of the faucets right now, because I removed that Flochek valve .... due to the false advertising on my circulator. Turns out, there's no damn IFC in there!
Came with my Amtrol Boilermate indirect hot water heater ... but I bought it at Lowe's in Worcester. Someone probably bought it, stole the circulator, installed their non-IFC circ and slapped the stickers on it, and returned it to Lowe's. Anytime you shop in Worcester, MA no matter what store, you gotta open the box BEFORE you leave the store. People pull that crap all the time. Goes to show the mentality & ethics of part of the populace ... but I digress....
No such thing as TOO MUCH hot water this winter! Been damn cold! My 2 series-plumbed hot water coils in the Mark III have sent my oil boiler north of 260° - YES .. TWO HUNDRED sixty ... several times. Melted all my insulation off the RETURN pipes!
This picture I took when I came home from work one day and smelt something funny coming from the basement. The floor was SOAKED from the relief valve blasting off, so who knows how high it really got while I was gone!

It's blasted off a few times while we were home, but never damaged anything. Ran it like that for 5 years.

Temper tank reached 180 degrees last night from running the furnace so hard so I filled the bath tub with hot water so the house could sponge up the extra heat. Worked really good!!
Hot tub went from 93 up to 100.
Who's Darwin lol

few thoughts from silly plummer, when sealing threads use 2-3 wraps of teflon, thenadd some loctite 737 thread sealant stainless threads are a pain in butt some times you have to wire wheel them first. also don't waste your time trying to re-solder used fittings start over with new. I've done a couple of thermosypon water heaters in which I installed sparco/honeywell mixing valves [same as some guys are using for radaint heat] they might be about 100 bucks but they are nice w/union mounts [easy install/ replacement if need be].

Lightning, did this setup work well the rest of the heat season? I'm thinking about installing a SS coil in mine, I already have a taco pump, just need the coil, some fittings and prv, and pex to hook it up to my electric dhw tank, I'm just worried about the water getting too hot due too only two of us living here, but was thinking about putting a small modine in in the garage as a kind of thermostat to control the temps as I've read some others here doing, but what do they do in a power outage? Just let the pop offs work? Lol

Yes, I've used this setup for two seasons now, this will be the third. Umm, do you plan to shut the electric off to the water tank once its installed? I leave mine on, and just send coal heated water to it from another tank in series with it.. You can always just fill yer tub with hot water and let the heat bleed off to the house if it gets too hot. The beauty of natural thermosiphon with a temper tank is that it doesn't need any pump at all..hotblast1357 wrote:did this setup work well the rest of the heat season?
Try to find an old hot water tank that you can use for a temper tank. Run it in series with your electric tank. Recovery time on the temper tank is pretty slow. Usually takes overnight to raise the whole tank 50 degrees. But if you don't use hot water for a couple days, you can imagine where this is going..

Right, I have a spare "temper" tank, but because of my low usage do I really need one? No I'm going to leave the electric on just incase, were always running the dishwasher or the washing machine, so maybe I won't have anything to worry about... But what about the unexpected events or short trips away from home ya know the "what ifs" lol

Here is whats gonna happen if you just plumb the coil to the electric tank.. Since recovery with the coil is so slow, the electric will be doing all the work to heat the water back up. Then once the electric tank reaches its thermostat temp and quits heating with electric, your coil in the furnace will continue to raise its temperature. You need the temper tank unless you plan to shut off the power to the electric tank.hotblast1357 wrote:Right, I have a spare "temper" tank, but because of my low usage do I really need one?
