Surburban DEM Gas Water Heaters utilize your motorhome's engine coolant to aid water heating with a "heat exchanger" to circulate the engine radiator coolant through an embedded tube on the external wall of the porcelain-lined steel tank as you drive. This method warms your water using engine heat in an environmentally efficient way. The motor aid option also increases the capacity of the engine cooling system in many instances. The water heater gas ignition is controlled by a switch mounted on the inside of your RV. Switch is sold separately.
The SW12DEM Model also lets you take advantage of campground or generator power to heat your water with the 1440-watt Incoloy electric element. The Incoloy electric element provides a recovery rate of 6.1 gallons per hour. For a faster recovery rate of 16.2 gallons per hour, use both gas and electric simultaneously.
Note: Gas appliances should be installed and/or serviced by a qualified service technician.
