Tank Storage Versus Tankless Flow
Hot water capacity
The Suburban 6-Gallon Gas and Electric RV Water Heater uses a 6-gallon storage tank with 4.0 gallons of usable hot water. It recovers 10.1 gallons per hour on gas and 6.1 gallons per hour on electric power. This setup provides a steady, pre-heated supply for multiple tasks. The Suburban 60,000 BTU RV Tankless Water Heater holds no water. It heats water only when you turn on the tap. This means endless hot water, limited only by flow rate and gas pressure. You get continuous supply with the tankless model, but limited reserve with the tank unit.
Energy efficiency
Efficiency differs based on usage patterns. The Suburban 6-Gallon unit uses exclusive flue tube technology to optimize heat transfer and save energy. However, it maintains a tank of hot water, which can lose heat when not in use. The Suburban 60,000 BTU model saves energy by engaging burners only when water is needed. It does not keep a reservoir hot. This on-demand approach eliminates standby heat loss. If you travel frequently and shut off the unit between uses, the tankless design avoids wasting energy keeping water warm. For constant use, the tank unit may be more efficient.
Safety features
Both units include robust safety mechanisms. The Suburban 60,000 BTU model features enhanced flame out protection that cuts gas supply during low pressure or burner malfunction. It also includes internal high-temperature kill switch for scald protection, limiting max output to 131 F. A child lock prevents outlet temperatures from exceeding 113 F. The Suburban 6-Gallon unit focuses on durability with a porcelain-lined steel tank and replaceable anode rod for corrosion protection. It does not list active temperature limiting or flame-out sensors in the same way. The tankless model offers more active thermal safety controls.
Physical dimensions
Size and weight impact installation space in your RV. The Suburban 6-Gallon unit measures 12.7 inches wide by 12.7 inches high by 12.7 inches long, weighing 32.9 pounds. It requires a cutout of 12.75 x 12.75 x 19.19 inches. The Suburban 60,000 BTU unit is 12 inches wide by 12 inches high by 20 inches long, weighing 21 pounds. The tankless model is lighter and narrower, making it easier to fit in tight spaces. The tank unit is more compact in width and height but heavier. You must check your available mounting area for both dimensions.
Power options
Power flexibility matters for camping. The Suburban 6-Gallon unit offers flexible power options with an optional electric element. You can use campsite or generator power for heating, or switch to gas. It has a 1,440-watt electric input. The Suburban 60,000 BTU model relies on gas for heating but includes active freeze protection and voltage protection that require electrical power. Voltage protection shuts down the unit during low or high voltage events. The tank unit allows direct electric heating without gas, which is useful when gas is unavailable or prohibited.
Warranty coverage
Warranty terms vary between the two models. The Suburban 6-Gallon unit is backed by a 2-year limited warranty and a 3-year tank limited warranty. This provides specific coverage for the tank structure. The Suburban 60,000 BTU product data does not list specific warranty durations. It highlights features like freeze and voltage protection but omits warranty details. Without explicit warranty data for the tankless model, you cannot compare coverage length directly. The tank unit provides clearer warranty terms in its specifications. You should verify current warranty policies for the tankless model before purchasing.
Choose based on your hot water needs
You need steady hot water for showers
The 6-Gallon model stores hot water, providing a continuous supply for multiple uses. It recovers 10.1 gallons per hour on gas and includes an electric element for campsite power. The porcelain-lined steel tank and replaceable anode rod ensure durability and corrosion protection for long-term reliability.
You want energy efficiency and safety
The tankless design heats water only when needed, saving propane. It features active freeze protection and voltage safeguards. Safety includes a high-temperature kill switch limiting output to 131 F and a child lock at 113 F. Flame out protection cuts gas during low pressure or burner issues.
You prioritize compact size and light weight
Weighing just 21 pounds and measuring 20 by 12 by 12 inches, this unit is lighter and fits standard cutouts. It requires a separate wall mount digital control center. The tankless form factor saves space in your RV compared to the bulkier 6-Gallon storage tank model.
