Dometic Tankless Water Heater Door Replacing Dometic 10 Gallon or Suburban 10, 12, or 16 Gallon

Which water heater openings does this Dometic tankless water heater door fit?

The doors in this collection are sized for the outside wall opening left by a Dometic 10 gallon tank water heater or a Suburban 10, 12, or 16 gallon tank water heater. If your RV currently has an Atwood 6 gallon unit, order the Dometic tankless water heater door for Atwood 6 gallon openings instead. Before ordering, read the make and gallon size from the data plate on your existing water heater.

Do I need to cut or patch my sidewall when replacing a Suburban or Dometic 10 gallon tank with a Dometic tankless water heater?

No. The replacement door covers the existing Suburban or Dometic 10 gallon opening, so you can install the tankless unit without enlarging or patching the siding. Follow the Dometic installation instructions for the gas, water, and 12V DC connections behind the door.

Is the Dometic tankless water heater included with the door?

No. This collection has the exterior access door only, and the tankless water heater is sold separately. You can compare tankless and tank models in our Dometic RV water heaters collection and order the heater and matching door together.

What if I decide to keep my Suburban tank water heater instead?

In that case you do not need this door. Anode rods, element parts, and other service items for your existing tank unit are in our Suburban RV water heater parts and accessories collection. Check your Suburban model number before ordering, because parts can differ between gas-only and gas/electric units.

How do I confirm the correct door before ordering, and how does shipping work?

Text or call 817-984-1852 with the make, model number, and gallon size of your existing water heater, and our team will confirm the correct Dometic tankless door the first time. Orders over $100 ship free.
