6 Best Electric RV Water Heater in 2026: A Practical RV Guide

Six 6 gallon RV water heaters with electric heating compared, from gas and electric hybrids to a plug-in tank, for campers who use shore power.

By Bowen HigginsRV Editor at RV Gear Lab6 products comparedSpec-sheet researched

An electric RV water heater saves propane at a campground and recovers slowly, since most RV outlets have limited amps. The best fit depends on whether you want electric only or a gas and electric hybrid.

The six picks include two Suburban 6 gallon heaters, three propane and electric hybrids and a plug-in electric tank. Gas and electric certifications are not claimed unless a listing names them.

RV Gear Lab field notes

The Rig Fit Check

Start with the job: Suburban SW6DE 6-Gallon RV Water Heater leads this shortlist for Suburban replacements. Use that fit as a reference point, then compare the alternatives against your own space and workload.
Specs that separate the picks: The first details to compare are 6 gallon Suburban DSI, 6 gallon propane and electric. Confirm the exact model and included components before ordering.
Trade-off to plan for: Needs correct cutout size

Before you buy

What Matters Before You Choose an Electric RV Water Heater

Key buying criteria so you get the right fit the first time.

01
Fuel modes
A hybrid runs on propane, electric or both, while electric-only needs an outlet. Choose by how often you camp with hookups. Check the listed modes.
02
Cutout fit
A drop-in must fit the 13 by 13 inch cutout. KINGRVER needs added clearance. Measure before buying.
03
Anode rod
A replaceable anode rod slows tank corrosion. Suburban and CAMPLUX list one. Look for it and plan to replace it.
04
Recovery and amps
Electric heating recovers slowly and draws amps. A shared 30 amp circuit limits other loads. Check the wattage.
05
Controls
An interior panel or remote saves a trip outside. CAMPLUX and KINGRVER list them. Check the control type.
06
Installation
Gas appliances need proper venting and gas connections. Follow the maker's manual. Check codes and certifications named on the listing.

FAQ

Before You Bring One Home

Can I add electric to a gas heater?

Some, via an element. Suburban SW6D lists an optional element.

What is the common mistake?

Ignoring cutout size. Measure the opening.

Is Suburban worth more than CAMPLUX?

For a Suburban design with an anode rod, yes. CAMPLUX White adds interior control.

How do I switch modes?

Use the interior panel or remote where listed. Follow the manual.

How often should I replace the anode rod?

Inspect it yearly and replace it when it is mostly consumed. A spent rod leaves the tank to corrode.
