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.
Aluminum Tank
The lightweight aluminum material makes it easier to handle and reduces the added weight to your RV. Unlike porcelain-lined steel tanks, an aluminum tank does not require an anode rod for protection, simplifying maintenance. The aluminum material also offers a longer lifespan due to its resistance to corrosion. Additionally, aluminum is a good conductor of heat, leading to more efficient heating.
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.
