I should done this years ago, living in the northeast, to keep the pipes from freezing. I would suggest this to anyone with forced hot water heating system.

We are full time RVer's & have had a difficult time finding the boiler antifreeze. The fact that it is in concentrate form makes it even better because it takes up less room when it has to be stored. Being able to order it from Amazon is so much easier than running from store to store.

Good price and smaller package. Not sure what color this will make when mixed with the green and yellow stuff we already have in the system. :)

This being thicker, you need to drain the container a bit longer so you don't waste it.

This only makes about a gallon but it's worth the extra couple bucks because of it's convenient and easy to store size. I always carry 3-4 gallons of distilled water anyway for my batteries so if I ever need it I'm ready to go. Stop thinking about the price and buy a few just in case. If your Hydrohot level is low it will not run so why not be prepared?

I have been using this in my motorhome for several years. I needed more and that is when I discovered that it now comes in concentrate. It makes storage a whole lot easier which is very important in an RV.

For solar hot water heater, usually have to replenish this product once annually. Thanks to Amazon because no one locally carries this product. Use distilled water for mix. Have a great day!

Specific for aqua-hot. I have used other boiler fluids, but this is specifically recommended. NOTE: this is NOT "RV Winterizing Antifreeze," which is also red. This is meant for use in hydronic heating systems in RV's.
