Antifreeze question

hr Member Posts: 6,106
in the galvanized fittings that will react with the inhibitors in the glycol.

If you wany cheap, RV antifreeze is about as cheap as you can find.

You might contact a glycol recycler for bargin anti freezes also. They collect used anti freezes, filter, ro then re inhibit and sell it to auto supply outlets. You might get some on the front end, from them, before it is recycled. Freeze protection would still be there, but inhibitors are used up. It will be a mix of PG and EG as newer cars now use PG, mostly, but it all gets drained into the same barrel. So toxicity would be questionable.

Why, with 800 gallons, would you need antifreeze? Rare to see open systems with anti freeze.

If you want real, real cheap dump some salt in the water :)

    Antifreeze question

    Here's the scenario:

    Amish built wood fired water heater/boiler and piping system. The piping is galvanized, don't know why but I do know this creates problems. The system is open.

    Anyone know off the top of your head what antifreeze to use that's "cheap" (his words).

    BTW system capacity is estimated at 800 gallons and he wants to go to -20*.

    I didn't ask. If the guy wants to buy that much antifreeze for a home-made "boiler" I guess that's up to him. Evidently they use the shop where the thing is 3 days a week and don't want to fire the wood eating beast the rest of the time. He said it would go through a face cord in three days just idling. I haven't seen it but it sounds HUGE! Like, you can park your truck inside the fire box. They throw in whole pallets without knocking them down.

    a more efficient unit :) Besides the huge amount of wood he could be a lot more friendly to the enviroment, with emissions!

    Or a small capacity boiler that loads an indoor insulated buffer tank instead of containing the BTUs in a 800 gallon system content?

    The gasification units make a lot of sense to me. A number of Euros are available and some US built www.woodgun.com
