Atwood Mobile Water Heaters

When it comes to dependable hot water solutions for recreational vehicles and mobile applications, Atwood Mobile has established itself as a trusted name in the industry. Founded in 1909 and acquired by Dometic in 2014, Atwood Mobile brings over a century of manufacturing expertise to its water heaters, delivering compact, efficient systems engineered specifically for the demands of life on the road.

Aluminum-Clad Tank Technology

Atwood water heaters feature aluminum-clad tanks that eliminate the need for an anode rod, simplifying maintenance while reducing weight—a critical advantage in mobile applications. These foam-insulated aluminum tanks prevent heat loss, ensuring that water stays hot longer and reducing the energy required to maintain comfortable temperatures. The aluminum construction resists corrosion better than traditional steel tanks, extending the service life of the unit even in harsh road and marine environments.

Versatile Fuel Options and Capacity Range

Atwood offers regular gas and electric RV water heaters, along with on-demand water heaters that instantly produce hot water. Their propane models heat water quickly—typically within 30 to 40 minutes—while dual-fuel propane/electric combination models provide flexibility based on available power sources at your campsite or dock. Models are available in 6-10 gallon capacities, allowing you to match your water heater to your specific space constraints and hot water demands.

Innovative Combustion and Ignition Systems

Atwood water heaters feature a patented "Through Tube" combustion chamber that utilizes the pilot flame to help maintain water temperature rather than losing heat to the atmosphere. Many models incorporate Direct Spark Ignition (DSI) for convenient remote lighting, while others use reliable pilot ignition systems. Atwood's "Relighter" feature serves to prevent pilot outage, ensuring continuous operation during travel or in windy conditions.

Flush-Mount Design and Serviceability

Atwood water heaters are mounted flush on the RV sidewall, maintaining a clean, integrated exterior appearance. Almost all serviceable components (95%) can be accessed through the exterior door, reducing service time without requiring technicians to enter your coach. This exterior-access design, combined with matching access doors available in popular colors, makes Atwood water heaters both practical and aesthetically compatible with a wide range of RV and marine installations.

Safety and Performance Features

Atwood Mobile water heaters incorporate multiple protection systems including thermostats, high-temperature limit switches, and pressure-relief valves to ensure safe operation. Fast recovery models produce hot water up to 7.4 gallons per hour at 70% efficiency, providing ample hot water for showers, dishwashing, and other onboard needs. Whether you're outfitting a travel trailer, motorhome, or marine vessel, Atwood Mobile's water heater lineup delivers the reliability and performance that mobile living demands.
