New RV Water Heaters

RV Water Heaters

Shop RV water heaters from Dometic, Suburban, and Girard for motorhomes, travel trailers, fifth wheels, toy haulers, and truck campers. Available options include propane water heaters, gas and electric models, traditional tank-style units, high-output water heaters, and tankless systems that provide hot water on demand.

Dometic RV Water Heaters

Dometic offers 6-gallon and 10-gallon RV water heaters in gas-only, gas and electric, and XT configurations. Dometic XT models use mixing-valve technology to provide more usable hot water than a conventional tank of the same physical size.

Current Dometic models include the WH-6GA, WH-6GEA, WH-9GEA XT, WH-10GEA, and WH-16GEA XT. Many current Dometic water heaters also replace select older Atwood models.

Suburban RV Water Heaters

Suburban manufactures tank and tankless RV water heaters in several sizes and configurations. Traditional Suburban tank models are available in 6-, 10-, 12-, and larger capacities with propane or gas and electric heating.

Suburban water heaters use porcelain-lined steel tanks with replaceable anode rods. Suburban also offers tankless models and Direct Fit replacements for select Atwood and Dometic installations.

Girard RV Water Heaters

Girard specializes in propane-powered tankless RV water heaters. The Girard GSWH-2 heats water as it flows through the unit, eliminating the fixed capacity and recovery time of a traditional storage tank.

Girard replacement packages are available for select 6-gallon and 10-gallon Atwood, Dometic, and Suburban water-heater openings.

Tank vs. Tankless RV Water Heaters

Tank-style RV water heaters store a fixed amount of heated water, commonly 6, 10, or 12 gallons. Gas and electric models may use propane, a 120-volt heating element, or both heat sources.

Tankless RV water heaters heat water on demand and can provide continuous hot water as long as the RV has sufficient freshwater, propane, 12-volt power, water pressure, and wastewater capacity.

Find the Correct RV Water Heater

Before ordering a replacement, locate the complete manufacturer and model number on the existing water heater. Confirm the tank capacity, fuel type, ignition system, electrical connections, installation dimensions, exterior door, plumbing, and required mounting components.
