Can the 65,000 BTU RV Tankless Water Heater provide enough flow for a truck camper?

You must ensure your plumbing has a 13 x 13″ opening and verify your propane supply can support 65,000 BTU of power before ordering.

The amzchef Propane Water Heater provides 3.9 GPM flow at high elevations

The 65,000 BTU output allows this unit to maintain hot water at 10,000 ft elevation, where a minimum of 60,000 BTU is required for consistent flow. We selected the amzchef Propane Water Heater for this analysis because it offers a 3.9 GPM flow rate that supports a steady shower for a family of four. This high flow rate is critical for RV tankless water heaters because narrow supply lines or low pressure can create bottlenecks that prevent the unit from reaching its stated capacity. The unit features staged combustion technology to manage heat and includes a 15 x 15″ door for easy access to the internal components.

What to Check Before Buying the amzchef Propane Water Heater

Because RV tankless water heaters rely on specific pressure and gas volumes to function, verify these site-specific details before installation:

• Confirm your truck camper’s water pump provides enough PSI to maintain consistent pressure under load.
• Verify there is sufficient clearance for the exhaust venting—the path for hot gases—and the intake to prevent heat-soak.
• Measure your propane regulator to ensure the supply line can provide enough gas flow to prevent pressure drops during peak heating.
• Check that your existing plumbing diameter is sufficient to pull in the volume of water the heater requires.

Comparing the amzchef Propane Water Heater to Other Options

The amzchef Propane Water Heater is a gas-powered unit that heats water on demand rather than storing it in a tank. Buyers seeking a compact footprint and high flow rates will find this model suitable, but those requiring a larger mixing tank—a reservoir that blends hot and cold water—might prefer different systems. If you need a unit with a larger internal volume for specific plumbing configurations, you may want to look at alternatives that include integrated mixing tanks.
