Here’s my opinion. Don’t get chemicals around where you’re running, if somehow that got into your run it could be BAD. Why not just drop an aquarium heater in your reservoir?Rusty”Knowledge is a paradox; the more one understands, the more one realizes the vastness of his ignorance” – Viktor (Arcane)The Horny Goat Build Thread

Heater be a good option ThanksJackfire

+1 on the aquarium heater it’ my goto for mash/ferments.However i do plug the heater connected into a secondary controller with a temp probe, just in case the heater thermostat sticks on, i did have that happen once.Reefer1

You considering this as a measure to raise the boiling point of your cooling water, or keep it from freezing?Fear and ridicule are the tactics of weak-minded cowards and tyrants who have no other leadership talent from which to draw in order to persuade.

Keep it from freezingJackfire

Vehicle antifreeze is Ethylene Glycol. It has a similar toxicity as Methanol. Propylene glycol is the food grade version that is added to Ice-cream . I agree, keep Vehicle antifreeze away from your stilling area . Alas the food grade version is about 10x the price . But whats the price of your loved ones .My recommended goto .wiki/index.ph … ion_Theory

This is Rv anti freeze ~ nontoxicJackfire

Maybe use diluted ethanol for antifreeze.30% would be none flammable and lower the freezing point to -18cOn second thought, the alcohol would raise hell with most pumps.

They also make a heater for cattle troughs. Also to keep The water from freezing. They work really well. I use them for my chickens. Depending on how big your water tank is, a fish aquarium heater might not be enough. You can pick them up at any grain store. Not sure how cold it gets there. But I’m way up here in Canada in igloo country and they work great.I drink so much now,on the back of my license it’s a list of organs I need.

There’s been a thread recently on barrel heating. Focused on ferm temps but i can’t see why one of the options wouldn’t work for your use case.viewtopic.php?t=93726

The product you are talking about is used to keep recreational vehicle potable water systems from freezing and breaking during winter months. Canadian winter months…. They are different. We just had a few days of -25*c. Not sure this is a thing in warmer parts of the planet. Our RV potable water system is drained and flushed with this product every year in the fall. Then it is drained and flushed with fresh water again in the spring when it is refilled with potable water.When I recirculated my coolant water I sure didn’t want it getting into my product! “What harms us is to persist in self deceit and ignorance”Marcus AureliusI’m not an alcoholic!

If you’re worried about your reservoir freezing between sessions, I second the stock tank heater mentioned above.My actual advice would be to go electric and do it in your basement.

Depending on how often you run it may not be a big issue. I use a 55 gallon barrel as my cooling water reservoir. If I either do a stripping run or spirit run 3 times in a two week period I rarely get more than a skim of ice. I do keep a board and blanket draped over the barrel when not in use. And the tank is sitting in an unheated metal building. In cases of a week of below zero weather I use the stock tank heater previously mentioned.

Depending on how often I operated the still and the volume of the reservoir … if a couple months went between runs, I’d just drain the reservoir and not have to worry about it during the coldest time of the year.4″ VM Build

How cold are you talking about the easiest way to lower the freezing point of water not to mention the cheapest was is just to add salt but even the sea freezes sometimes so it depends on how cold your area gets

Kinda what I was thinking. In my neck of the woods, tap water costs around $.01 a gallon, electricity is around $.12 kwh.
