Seems like it would be hard to balance flow , keep a loop from getting air bound and also what do you do if you want to stop heating te floor in the cold months as far as freezing goes?

You're right on the separating the floor to run glycol.
By balancing flow do you mean achieving hydraulic separation between the floor circ and furnace circ?

[slimjim]

Correct me if I'm wrong but if you are sending water directly from the OWB to the slab via a mixing valve then there would be no need for a separate circ, one would do the job in Va. not sure that would work for a week long power outage at 20 below zero or anything below freezing for that matter, anytime a slab is used, I certainly would use a plate and anti freeze north of the Mason Dixon!

Never heard that phrase before Slim, good one!

I used a pressurized system with a plate heat exchanger like mlappin said so I could just use antifreeze in the floor and not the entire system. Can get pretty cold in Wisconsin and the last thing I want is a burst pipe in the floor if I have to shut it down for some reason.

What ever works for you though.

I guess wood burning is about gone here, loosing 25 to 30 gallons every other day. Would be impossible to run another piece of Logstor under the road, if that is the problem. Might have time tomorrow to dig a little deeper.

Boy I would be surprised is it's a logstor failure.

[coolidge]

I hope not, got some testing going on, there is NO circulation too the boiler at this time, need to squirm into the crawl space ( not shure if I can fit) and see if there is any wet spot from the radiant.

My first year with an OWB I had issues like that. It was not the unit I have now but it wasn't the unit's fault anyway, I used sharkbite clone push fittings back then. I was told they are just as good as sharkbite-WRONG! Lost all my antifreeze treated boiler water back then.

I replaced all of them using mostly crimp fittings but only using sharkbite where I needed push type fittings. No problems since.

[coolidge]

No shark bites,  Logstor to copper to zones.  I am going to have to refire today, wife, kids and animals are cold.

Bonus,   Found the leak, black iron nipple for my pressure relief valve rusted.

LOL, hows that saying go, if you can’t be good then be lucky?

My father was a union tin knocker before entering the state of retired bliss, several places he’d work for in the past he was the guy they always send out to find a mystery leak in a roof, most of the time it was because somebody got lazy and didn’t properly tool the caulk after applying it, some were real head scratchers though. Tough ones to find were either slate roofs or standing seem copper roofs, usually on the copper somebody made a bad solder joint.

Just happened to catch a drip in the basement from underneath my storage tank, there was 6" of foam around that nipple, started digging and wala.

That one is fixed.

We bought a combine cheap years ago, got it home then found out why, sit long enough and it would loose prime.

Talked to the local dealer, claimed they had their guys work on it numerous times and could never figure it out.

Pressure washed everything, gunked it all then pressure washed again, ran the engine to dry everything out, couldn’t find anything.

Next day was climbing up the service ladder to get behind the engine, happened to be looking right at the shutoff solenoid on the injection pump and seen a tiny little drip. Went and got a flashlight, watched it, would get one tiny little drop every 12-15 minutes, wouldn’t leak at all when warm. Sometimes would only take four days to loose prime, sometimes a week or better. replaced solenoid and end of problem.

Dumb luck on that one, as the drip would land right on a hose and follow that elsewhere.

[coolidge]

Crete done.

[hondaracer2oo4]

Boy you don't screw around!

No time, winter is coming
