Do you have a sketch of the pipe diagram? Maybe we could help with that to, usually it's very simple with a flat plate a pump and a strap on limit to cut the burner off on the gas boiler.
Thanks for all the input. Never had to pipe one up. Owner is not doing the antifreeze. Pumps can run all the time on this so it sounds like he will be ok.....again thanks...I learned something.
i was told the additive acts as a low grade antifreeze.
I agree with the owner don't put glycol in it. Pipe it so the pump can run continuous and it will take days to actually freeze up. Hundreds of them here in northern WI and I only know of one that runs glycol, and its because he leaves for a week at a time.
We treat the water but never heard of glycol in them, as stated its an open system and will run low on water. If for some reason the pump fails the water in the boiler won't freeze with a fire going, and if they let the fire go out maybe it's not work spending the big bucks If they don't use it all of the time, you can also heat the water outside with the plate to plate when the indoor boiler is firing, it works both ways.
I know little, but as a rule water is only treated for rusting as it's an open system and some don't even do that. I guess the feeling is the only time it could freeze is if wood isn't added and that isn't done often, so no need for anti-freeze.
Outdoor wood boiler question I'm not sure if I'm in the right forum, but here is my question. I have very good commercial customer who owns a plastics factory, and commercial office space that hires us for everything. He hired me to hook up his outdoor wood fired boiler to his house and garage. House has in floor radiant, and domestic hot water will be run off this too, garage has in floor also. They installed everything and buried the pipe etc, he hired me to engineer it and make it work. That being said I contacted my wholesaler and along with our B&G rep, came up with a plan and diagram. It employs braze plate heat exchangers because I want to add glycol to the outdoor section. There is back up heat inside both structures, but outdoors if the fire goes out, or a pump fails, stuff is gonna freeze outside. My customer does not want glycol ...says the guy who sells the boiler said nobody puts glycol in them (????). We are in central New York. It gets cold here. Any thoughts or experience with these? Thanks.
