RV Water Heater Bundles

What is included in an RV water heater bundle?

Each bundle pairs a complete RV water heater unit with the install-critical parts most owners forget on the first order: door, anode rod or drain plug (depending on tank type), and the gaskets needed to seal the flange. The goal is a single SKU that gets your replacement job done without a second shipment. Confirm your existing cutout dimensions and fuel/ignition type (LP, DSI, electric, or LP/electric combo) before ordering.

How do I know which water heater size fits my RV?

Measure your existing cutout in the sidewall, typically 6-gallon units use a 12.75" x 12.75" opening and 10-gallon units use a 16" x 16" opening. Tank capacity should match what your rig was built around; going larger usually means cutting sheet metal and rerouting plumbing. If you have a 10-gallon cutout, see our 10 gallon RV water heater collection for direct-fit options.

Do I need to replace the anode rod when installing a new water heater?

Only Suburban water heaters use a sacrificial anode rod (the tank is porcelain-lined steel). Atwood and Dometic units have an aluminum tank and use a plastic drain plug instead. Installing the wrong one will damage the tank or cause leaks. The bundle ships with the correct part for the unit included.

Should I winterize the new water heater before storage?

Yes. Drain the tank, bypass it with the water heater bypass valve, and run RV antifreeze through the rest of the plumbing. Leaving water in the tank during a freeze will crack the inner liner or split fittings. Our RV winterizing kits have the bypass valves, pump converters, and antifreeze you need for a full system flush.

Do these bundles ship freight or standard ground?

Water heater bundles ship via standard ground in most cases since the unit and accessories fit within carrier size limits. Orders over $100 ship free. If you need help confirming fitment or shipping timing, text or call our team at 817-984-1852.
