Buying Guide: Key Considerations for a Water Heater Conversion Kit
What tank size and brand are you targeting?
Most kits are designed for 6-gallon RV tanks from Suburban, Atwood, American, and More-Flo families. Verify compatibility with your exact model and confirm that the mounting surface and internal fittings allow for a heating rod installation.
Is 120V electric operation feasible on your RV’s electrical system?
Assess whether your electrical system can provide the required amperage for continuous hot water. Some kits require dedicated circuits or upgraded breakers. The thermostats should offer reliable temperature control to avoid scalding or freezing.
How important is a complete, plug-and-play setup?
If you want minimal wiring effort, kits with color-coded cords, pre-wired thermostats, and included brackets provide faster, more predictable installation. Non-integrated kits may require more customization and professional assistance.
What safety features matter most?
Look for independent switches, secure mounting brackets, and watertight connections. An adjustable thermostat helps maintain consistent water temperatures without overheating the tank.
What are potential installation limitations?
Some kits assume space on the tank surface for mounting. Others require access to the anode/drain area for the heating rod. If you travel in cold climates, consider a model with a temperature range suited for freezing protection.
Frequently Asked Questions
Do water heater conversion kits work with all RV models?
Most kits target common 6-gallon Suburban, Atwood, American, and More-Flo tanks. Check compatibility with your exact model before purchasing.
Is professional installation recommended?
Many buyers can install these kits themselves if they have basic wiring skills and follow the included instructions. Complex electrical upgrades may require a licensed technician.
Can I use propane and electricity together after conversion?

Will these kits affect warranty coverage?
Modifying a water heater may impact the manufacturer’s warranty. Check with the OEM or retailer for warranty implications before installation.
What maintenance is needed after installation?
Inspect wiring connections, thermostat settings, and the heating element periodically. Ensure the water tank remains free of leaks and that mounting brackets stay secure.
