Hot Water (up to 200°F) is water stored or processed at elevated temperatures, up to about 200°F (93°C), for washdown, cleaning, boiler feed, process heating and heat recovery systems. At these temperatures plastics lose strength, so tank resin, wall thickness, fittings and gaskets must be rated for continuous hot service. Standard HDPE tanks are not intended for continuous water above about 120°F (49°C). Use the compatibility ratings to choose the right tank resin, fittings and gaskets.
HDPE is the most economical tank material for Water - Hot - Up to 200 F., rated Excellent. Polypropylene, nylon and PVDF (Kynar®) are also rated Good or better.
