33G 151L 42.75 x 22 STID40 Indirect Water Heater

Built to last– tank is manufactured from heavy gauge steel. Longer life equals a higher “return on investment”. Outer jacket is made from steel and powder coated for a lasting, durable finish. | 2" Non-CFC foam insulation – provides superior insulating quality and decreases standby heat loss. | 1-1/2" Coil diameter – larger diameter, results in higher recovery and less pressure drop through the coil – smooth surface on the coil resists lime build-up. | Factory installed dielectric nipples – provide greater insulating protection against electrolysis. | temperature porcelain enamel protects all tank and coil – and maximizes corrosion resistance. | Factory installed automatic temperature controls – immersion aquastat on all models. | Two heavy-duty magnesium anode rods – inhibit corrosion and maximize tank life. | Sediment reduction inlet – standard on the STID80 and STID120. Reduces sediment buildup on the tank bottom – increasing operating efficiencies and tank life. | Temperature and pressure relief valve – CSA/ASME rated and factory installed. | Factory installed brass drain valve
