American direct solar water heaters are designed for installation as a part of a direct (open loop) solar water heating system or for use with external heat exchangers in closed loop systems. Available in 65, 80 and 119-gallon capacities these models provide storage for the hot water produced by the solar collectors and a supplementary electric heating element that maintains consistent water temperature during periods when solar energy is not available. Multiple Connection Options for Installation Flexibility Side and top connections for open loop systems or closed loop systems using an external heat exchanger Electrical 4500 watt heating element - long lasting low-watt density design spreads wattage over larger surface area to prolong element life and maximize efficiency Pre-wired for surface mount temperature sensor (sensor supplied separately) Tank Construction Glasslined Steel Tank – glasslining protects against corrosion to maximize tank life 2-inch thick “Environmentally-Friendly” Non-CFC Foam insulation (R16 Value) reduces standby heat loss Anode Rod Anode rod with stainless steel core protects tank against corrosion CSA Certified and ASME Rated T&P Relief Valve Durable Tamper-Resistant Brass Drain Valve Compliance Units are UL and cUL listed to UL 174 Standard for Household Electric Storage Tank Water Heaters and CAN/CSA-C22.2 No. 110-M90; Complies with California legislation AB 1953 and Vermont legislation Act 193 that limits the lead content in plumbing fixtures that come into contact with drinking water to a maximum of 0.25%.
