Dometic RV Water Heaters

Which Dometic RV water heater models do you carry?

Our Dometic RV water heater lineup covers the current tank models including the DMC74FR 6-gallon unit, replacement tanks, and matching service parts. Each listing includes the OEM part number and tank capacity so you can match the unit you are replacing without guesswork. If you need a larger capacity, see our 10 gallon RV water heater options.

Does Dometic make a tankless RV water heater?

Dometic's RV water heater line is built around tank-style units like the DMC74FR rather than true tankless designs. These gas/electric tank heaters deliver consistent hot water output and use standard mounting cutouts, which makes them a direct fit for most factory installations. Confirm your existing cutout dimensions and fuel type (LP, electric, or both) before ordering.

How do I find the right Dometic water heater tank replacement?

Match the replacement tank to your existing model number, capacity in gallons, and ignition type (DSI or pilot). The DMC74FR, for example, uses a 6-gallon tank with specific port and anode rod locations. Pull the model tag from the outside access door before ordering, and pair the swap with a fresh anode rod and drain plug to finish the job correctly.

What does it cost to ship a Dometic RV water heater?

Full water heater units typically ship via standard ground freight, while smaller service parts qualify for free shipping on orders over $100. If you are also winterizing the rig, check our RV winterizing kits to protect the new tank through the off-season. Questions on fitment? Text or call 817-984-1852.
