Propane Operation
This water heater utilizes a propane-fired burner to route heat through a passage in the tank, transferring the heat to the water stored in the tank. 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. This feature requires a 12V DC connection to power the control board and igniter.
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.

    SSW4D RV water heater

    Posted by George Urban on Dec 18th 2025

    Let me say that Panther rv was very helpful and prompt with my purchase. With that being said the Suburban water is well built and easy to install. My problem is with there quality control, after I installed the heater I did a water pressure test , when I went to drain the heater I found that the anode rod was crossed threaded and only in by 2 threads. I had to tap out the drain myself to get the rod to seat properly. I then notified Suburban about their quality control and have yet to hear back from them. My answer is to check the unit Before you install it.

    Ours has worked well for us for the last 3 years. This means it was 10 years old when a leak finally developed. Installing the new one was not terribly hard to do. It’s just that working inside a truck camper is a spacious place. Water heater took off right away when I tripped the switch. I’m happy with it.
