Hatco S-18 Description


The Hatco S-18 Imperial booster heater heats water to a sanitary 180 degrees Fahrenheit, and the thermostat can also be set to 140 degrees for use with low-temp dishwashers. Heating is provided by multiple metal-sheathed elements to help prevent burnouts. Ambient compensating thermostats ensure the temperature is precise, and the unit has a built-in heat trap and fiberglass insulation to keep the heat contained.

Its tank can hold 16 gallons and has a Castone® lining to protect the components and add durability. There is a low-water cutoff to prevent burnouts from low water levels and a high-limit control to shut off power if the unit overheats. The Hatco S-18 Imperial booster heater has a durable exterior with a stainless steel front and hammertone body that stands on 6-inch-tall plastic legs. Maintenance can be performed with ease from the front.
