The New Super Hot stainless steel indirect water heater offers the best in performance, reliability, and efficiency and is the perfect companion to High Efficiency HSE boilers and long lasting atmospheric Mini-Gas and Saturn Series boilers.
Available Capacities: 40, 56, 79 and 119 US Gallons.
Stainless Steel Construction: EPJ Tanks are formed out of Grade 444 Stainless Steel which is ideal for hot water tanks because of its superior corrosion resistance, low maintenance, and durability. Stainless steel is safe, hygienic, strong and light in weight.
Passivated and Pickled: The manufacturing process for welding stainless steel interferes with the chromium oxide layer that protects stainless steel. Therefore, in order to restore the so-called passive layer, which makes stainless steel corrosion resistant, a thorough after treatment called pickling and passivating is necessary. This process guarantees that the passive layer is restored completely.
Attractive: The water heater is encased by a durable, scratch and dent resistant, polypropylene plastic cover. The attractive blue top and white jacket make the EPJ-Series aesthetically pleasing.

FEATURES
Industry Leading Recovery generates up to five times more hot water than a typical direct fired gas, electric or oil water heater. Heat transfer efficiency is achieved through a unique concave spiral heating coil with a double-loop drop which completely heats the bottom of the tank, provides faster recovery and eliminates potential bacteria. The result is exceptional performance for first hour ratings and continuous delivery of hot water for showers, faucets, dishwashers, and laundry.
Two Inch Thick High Quality EPS Foam Insulation minimizes standby or off cycle heat losses. Energy saver side (in-line) water connections eliminate heat loss by creating a “thermal trap” to stop convective flow and radiant losses from the top of the tank. When necessary, the two piece foam shell and top is easily removed for inspection or recycling.
Light Weight EPJ Indirect Water Heaters save time and transportation costs. The light weight EPJ allows for quick and easy installation without the need for an extra person or special handling equipment.
Limited Warranty Durable long life 444 Stainless Steel gives you peace of mind and protection for years to come, backed by Allied’s (non pro-rated) warranty. Refer to warranty details for terms and conditions covering EPJ-Series for residential and commercial applications.
