Ranein vs Suburban RV Specs
Fuel type
The Ranein 65,000 BTU RV Tankless Water Heater runs exclusively on propane gas. It uses a 12V DC system to power its internal components, including the burner and controls, while relying on gas for the actual heating process. This setup is standard for many modern tankless RV units. The Suburban SW6DE offers more flexibility. It is a gas and electric model. You can heat water using its 12,000 BTU gas burner or switch to its optional 1,440-watt electric element. This dual-fuel capability allows you to use campsite power or generator electricity when gas is unavailable or when you want to conserve propane. This versatility is a significant practical advantage for many RVers.
Capacity
These two units operate on fundamentally different principles regarding hot water storage. The Suburban SW6DE is a tank-style heater with a 6-gallon capacity. It stores hot water in a porcelain-lined steel tank, allowing it to provide a fixed amount of hot water before needing to recover heat. The Ranein unit is a true tankless model. It does not store water. Instead, it heats water on demand as it flows through the unit. The Ranein delivers a continuous flow rate of 3.9 GPM. This means you get hot water indefinitely, limited only by your propane supply and incoming water pressure. The Suburban provides a recovery rate of 10.1 gallons per hour on gas. For long showers, the tankless design of the Ranein avoids the cold water sandwich effect common in tank models.
Flow rate
Flow rate determines how much hot water you get at once. The Ranein unit provides a flow rate of 3.9 GPM. This is a robust output for an RV, allowing for comfortable showers and potentially simultaneous use of multiple faucets without significant temperature drops. The Suburban SW6DE does not list a GPM rating in its specifications. As a tank heater, its performance depends on the recovery rate, which is 10.1 gallons per hour on gas. This translates to roughly 0.17 GPM of recovery, which is much lower than the Ranein's continuous flow. The Ranein’s 3.9 GPM output ensures stronger pressure and steady temperatures, making it better for users who value high-flow showers or need to run multiple fixtures at once.
Voltage
Electrical requirements differ between the two models. The Ranein RV Tankless Water Heater is powered by a 12V DC system. This integrates directly with standard RV 12-volt electrical setups, drawing power for its ignition, fan, and control board. It does not require 120V AC power for operation. The Suburban SW6DE also uses 12V DC for its Direct Spark Ignition (DSI) system. However, it also includes an optional 1,440-watt electric element that requires 120V AC power. This means the Suburban can operate on 12V for gas heating but needs an inverter or shore power for electric heating. The Ranein is simpler in terms of electrical needs, as it relies solely on the 12V system for all functions.
Build
The construction materials highlight different durability approaches. The Ranein uses an oxygen-free copper heat exchanger. Copper offers excellent heat transfer efficiency and is naturally resistant to corrosion, which is important for longevity in varying water conditions. The unit weighs 15.5 pounds and features a silver exterior. The Suburban SW6DE uses a porcelain-lined steel tank. This is a traditional construction method designed to mimic residential tank heaters. It includes a replaceable anode rod to protect the steel from corrosion. The Suburban is heavier at 32.9 pounds. The Ranein’s copper core may offer better thermal efficiency, while the Suburban’s steel tank provides a proven, robust storage vessel. Both designs aim for long-term reliability in RV environments.
Installation location
Both units are designed for RV installation but fit different spaces. The Ranein has dimensions of 15 x 15 x 15 inches. It is designed to replace most Suburban and Atwood 6, 10, or 12-gallon tank water heaters that have a 12.8-inch opening. The Suburban SW6DE has dimensions of 12.7 x 12.7 x 19.19 inches. Its cutout dimensions are 12.75 x 12.75 x 12.75 inches for the base, but the full height is nearly 19.2 inches. The Ranein is more compact in height, making it suitable for lower clearance areas. The Suburban is taller, which may require more vertical space. The Ranein is a direct replacement for many older tank models, whereas the Suburban is the original equipment it replaces. You must check your specific RV cutout dimensions before choosing.
Which tankless water heater fits you
Shower-focused travelers needing high flow
The Ranein delivers 3.9 GPM with 65,000 BTU power. This combination supports simultaneous faucet use and longer showers without temperature drops. Its thermostatic mixing chamber stabilizes output. You get reliable hot water for full-time RV living or cold climates. The high flow rate ensures consistent pressure and comfort for multiple users.
Campers wanting dual gas and electric heat
The Suburban SW6DE offers flexible power options. You can use propane gas or connect to campsite electricity via its 1,440-watt element. This versatility suits boondockers and full-hookup campers alike. The porcelain-lined steel tank provides durable construction. You gain the ability to switch heat sources based on your camping setup and energy availability.
Users replacing standard 6-gallon tank heaters
The Suburban unit is designed to replace most 6-gallon tank water heaters. Its compact dimensions fit standard RV cutouts easily. The 6-gallon capacity provides stored hot water. You benefit from a familiar form factor with advanced corrosion protection. The replaceable anode rod simplifies maintenance. This model ensures reliable performance for those preferring traditional tank-style storage.

Frequently asked questions
Is the Suburban 6-Gallon a true tankless water heater?
No, it is not. The Suburban unit is a compact storage tank heater with a 6-gallon capacity. It stores hot water for later use rather than heating it on demand. This means you have a limited supply that can run out if you use more than the tank holds. The Ranein model, by contrast, provides continuous hot water without running out.
Which unit is better for cold weather RV camping?
The Ranein 65,000 BTU model is better for cold weather. Its high BTU output allows it to raise the temperature of incoming cold water effectively. It is specifically noted for high-flow performance in cold conditions. The Suburban storage tank relies on insulation to keep water warm and does not have the same heating power to combat freezing inlet temperatures.
How do the dimensions of these two heaters compare?
The Ranein unit measures 15 inches wide, 15 inches high, and 15 inches long. The Suburban model is slightly smaller at 12.7 inches in each dimension. Despite being smaller, the Suburban is heavier at 32.9 pounds compared to the Ranein’s 15.5 pounds. The Ranein’s cubic shape offers a different footprint than the Suburban’s compact square design.
Does the Ranein heater require electricity to operate?
Yes, it uses a 12V DC system to power its internal components. This includes the burner ignition and electronic controls. It does not use electricity for the actual heating process, which relies on propane gas. You need a power source for the electronics, but the heat comes from burning gas, similar to traditional RV appliances.
Can I use the Suburban heater on propane?
Yes, the Suburban unit offers dual fuel flexibility. It can operate on both electric and gas power sources. This allows you to switch between shore power or generator power for electric mode, and propane for off-grid camping. The Ranein unit, however, runs exclusively on propane gas and does not offer an electric heating option.
Which model is lighter and easier to install?
The Ranein model is significantly lighter at 15.5 pounds. The Suburban unit weighs 32.9 pounds due to its steel tank construction. The lighter weight of the Ranein may simplify mounting in your RV. Both units have compact footprints, but the Ranein’s lower mass makes it easier to handle during installation or relocation.
What is the main difference in hot water delivery?
The Ranein provides continuous hot water as long as gas is supplied. It heats water instantly as it flows through the unit. The Suburban delivers stored hot water from its 6-gallon tank. Once the tank is empty, you must wait for it to reheat. The Ranein is better for long showers, while the Suburban is better for short, intermittent uses.
