This is a warranty requirement. Table 6 provides guidelines for determining the correct amount of antifreeze. Enertech recommends using the 20 year Extreme Annual Temperature shown in the ASHRAE Fundamentals Handbook, Environment Canada, or local weather data. - Page 59 In most areas of North America, 25% to 30% is sufficient for burst protection. In Northern U.S. and some Canadian climates, 35% or more must be used. Enertech recommends 25% or higher concentration, depending upon location. Lower concentration provides better heat transfer and lower viscosity, but may not provide enough burst protection.
