As an Amazon Associate we earn from qualifying purchases. Links on this page are affiliate links.
The Camco 6-Gallon RV Hybrid Heat Conversion Kit lets you add 120V electric power to an existing propane tank. You might look for camco hot water hybrid heat alternatives if you need a different capacity, a different brand, or a standalone unit rather than a conversion kit. Some users prefer a dedicated under-sink heater or a higher-flow tankless model instead of modifying their current RV water heater.
We selected these options because their specifications overlap with the original product’s core function: providing hot water in RV or compact spaces. Each alternative offers distinct specs, such as varying wattage, tank size, or fuel type. You can compare these details to find the fit for your specific setup. This list covers different approaches to solving the same hot water challenge, from mini-tanks to propane tankless heaters.
How alternatives compare to Camco
Fisoceny 4-Gallon 1500W Under-Sink Water Heater
The Fisoceny 4-Gallon unit is a self-contained electric tank rather than a conversion kit. It uses a 1,500W element, which heats water much faster than the Camco’s 425W conversion element. You get a complete 120V solution for under-sink or RV use without modifying an existing propane tank. It sacrifices the ability to run on propane, so you must have reliable 120V power. The 4-gallon capacity matches the usable output of the Camco setup but in a standalone white unit. Choose this if you want dedicated electric point-of-use heating and do not need dual-fuel flexibility.
KENUOS 4-Gallon Mini-Tank Water Heater
The KENUOS 4-Gallon Mini-Tank offers a 1,500W heating element, providing significantly faster recovery than the Camco’s 425W conversion kit. It is a complete 120V unit designed for under-sink or RV installations. Unlike the Camco kit, which modifies an existing tank, this is a standalone appliance. It includes dual-size connection hoses and safety valves for easy integration. You give up propane backup capability, relying solely on electricity. The compact footprint suits tight spaces. Pick this alternative if you prioritize rapid hot water delivery and want a ready-to-install electric tank without the complexity of retrofitting a propane unit.
VELPAX Outdoor Propane Tankless Water Heater
The VELPAX Outdoor Propane Tankless Heater provides 110k BTU of heating power, vastly outpacing the electric conversion capabilities of the Camco kit. It is designed for outdoor use and high-flow demands, making it suitable for RVs or homes with outdoor water needs. You gain remote control functionality and continuous hot water on demand. However, it requires propane fuel and outdoor installation, unlike the indoor RV application of the Camco. It lacks a storage tank, so you get instant heat rather than stored hot water. Choose this if you need high flow rates and have outdoor space for installation.
RIWORY RV Propane Tankless Heater
The RIWORY RV Propane Tankless Heater offers a propane-powered solution for RVers who want to avoid 12V wiring complexities. It provides a 120V upgrade option for freeze protection while maintaining propane heating for hot water. Unlike the Camco kit, which converts a 6-gallon tank, this is a tankless unit. It weighs 24 pounds and measures 13 inches on each side. You gain continuous hot water and freeze protection without modifying an existing tank. However, you may need to source a door separately for installation. Pick this if you prefer tankless efficiency and want to skip 12V electrical work in your RV.
Thermomate 4-Gallon Point-of-Use Electric Water Heater
The Thermomate 4-Gallon Point-of-Use Electric Water Heater is a standalone electric unit designed for single-sink setups. It delivers reliable heating for small spaces where compact size and safety certifications are priorities. Unlike the Camco conversion kit, it does not utilize an existing propane tank. It operates on 120V power and has a 4-gallon capacity. The unit weighs 19.8 pounds and measures 12.9 by 18 by 14.5 inches. You sacrifice the ability to use propane, relying entirely on electricity. Choose this alternative if you need a simple, certified electric heater for a single sink and do not require dual-fuel options.
Suburban 6-Gallon Gas and Electric RV Water Heater
The Suburban 6-Gallon Gas and Electric RV Water Heater provides dual-fuel reliability with efficient propane heating and electric backup. Unlike the Camco kit, which adds electric capability to a tank, this is a complete unit with both fuel sources integrated. It features a 6-gallon capacity and weighs 32.9 pounds. The steel construction offers durability for RV use. You gain the flexibility to switch between propane and electric power depending on availability. However, it lacks the instant-on speed of tankless models. Pick this if you value tank reliability and dual-fuel flexibility over rapid recovery rates in your RV setup.

Frequently asked questions
Can I use these alternatives for my RV?
Yes, several options work well in recreational vehicles. The Camco 6-Gallon kit, Fisoceny 4-Gallon heater, KENUOS 4-Gallon unit, VELPAX propane heater, RIWORY propane heater, and Suburban 6-Gallon heater are all listed for RV use. You can choose based on whether you need a conversion kit or a standalone tank.
Which alternative is best for under-sink installation?
The Fisoceny 4-Gallon, KENUOS 4-Gallon, and Thermomate 4-Gallon units are designed for under-sink use. These mini-tanks provide point-of-use heating for small spaces. They all operate on 120V power, making them suitable for kitchens or bathrooms where a compact footprint is necessary.
Do I need a 240V outlet for these heaters?
No, all listed alternatives operate on 120V power. The Camco conversion kit, Fisoceny, KENUOS, RIWORY, Thermomate, and Suburban units all use standard 120V electricity. This allows you to plug them into existing RV or home outlets without installing new high-voltage circuits.
What is the difference between tankless and tank alternatives?
Tankless models like the VELPAX and RIWORY provide hot water on demand without storage. Tank alternatives like the Camco, Fisoceny, KENUOS, Thermomate, and Suburban units store heated water. Tankless units offer continuous flow, while tanks provide a reservoir of hot water for multiple uses.
Are propane options available if I lack electric power?
Yes, the VELPAX and RIWORY units run on propane. The VELPAX is an outdoor tankless heater, while the RIWORY is an RV propane heater. These options allow you to heat water without relying on electrical connections, which is useful for camping or off-grid RVing.
Which unit has the largest water capacity?
The Camco 6-Gallon kit and Suburban 6-Gallon heater have the largest capacity among the tank options. They hold six gallons of water. The other tank models, including the Fisoceny, KENUOS, Thermomate, and Suburban, have a four-gallon capacity, which is smaller but still effective for point-of-use needs.
Can I control these heaters remotely?
The VELPAX outdoor propane tankless water heater includes remote control capabilities. This allows you to adjust settings from a distance. The other listed units do not mention remote control features in their specifications, so you will likely need to adjust them manually at the unit.
