Valterra HR6P2 Heating Element
The market is flooded with generic replacement parts for RV water heaters, but the Valterra HR6P2 heating element stands out by being the official, engineered replacement for a specific and popular system.
Where It Excels
- It offers enhanced protection and compatibility compared to universal elements, as it’s designed specifically for the Hot Rod kit.
- You get guaranteed fit and performance for your Suburban water heater, which is a major advantage over guessing with third-party parts.
Where It Lags
- It comes at a higher price point than no-name heating elements you might find online.
- Its use is strictly limited to the official Hot Rod 6-gallon conversion kit, so it’s not a universal solution.
Pick this if guaranteed compatibility and maintaining your Hot Rod kit’s integrity matters most. If you just need any heating element and are comfortable with modifications, a cheaper generic might suffice. But for a direct, worry-free replacement, this is the reliable choice.

Diamond Group HR10 Hott Rod
If you’re searching for the best hott rod water heater conversion kit gallon for gallon, the Diamond Group HR10 is a fantastic upgrade that makes RV life noticeably more convenient.
Pros
Installation is straightforward and the kit works exactly as promised. I love that it preserves my existing propane system, giving me the flexibility to choose my heat source.

For the price and performance, this conversion kit earns its spot as a top-tier upgrade. It adds real value by simplifying camp setup and cutting down on fuel costs, making those long showers at a full-hookup site even more enjoyable.
