Propane and Electric Operation

This RV water heater offers versatility with its dual power source capabilities, allowing it to operate on propane, electric, or a combination of both for an improved recovery rate. When using propane gas, a propane-fired burner routes heat through a passage in the tank, transferring the heat to the water stored in the tank. Alternatively, the electric option uses a 120V AC heating element to heat the water, much like a traditional household water heater. This model features an automatic spark ignition system, also known as a direct spark ignition (DSI), making it easy to operate. To start the heater, simply ensure that it is filled with water and flip the switch. A 12V DC connection is required to power the control board and igniter.

DE vs DEL Models

The Suburban water heater models DE and DEL differ in their wiring requirements. The DE model features a switch on the water heater to control the 120V operation and a separate switch is required inside the RV cabin to control the propane operation. On the other hand, the DEL model requires a dual switch located inside the RV cabin that controls both the 120V and propane operation.

Porcelain Lined Steel Tank

Built with a durable steel tank that is lined with porcelain for added protection and longevity. This type of construction is also used in most residential water heaters, ensuring that it can withstand various water conditions. An anode rod is included to further extend the life of the tank by protecting it from corrosion. The tank also features an insulation jacket that is custom fit to the tank for maximum heat retention, this will help in reducing the energy consumption and keep the hot water hotter for longer period of time.

Electric Ignition

The electric ignition eliminates the hassle of manual lighting of your water heater. The electric ignition utilizes a control board that sends an electrical signal to the igniter, which then creates a spark to ignite the propane burner. Simply flip the switch (not included) to start the water heater, making it more convenient and easier to use.
