My father built a pole barn with in-floor hydronic heating. We are just now getting around to adding the heat source (7kw Electro industries Off-peak boiler).
He is located in Minneapolis MN so the 99% design temperature is -9.4°F.
We are looking to use a Cryo-tek 100 anti-freeze mixture.
In relation to the design temperature, which protection rating should we be targeting? Both category and temperature?
Thanks
