A 65,000 BTU propane tankless heater is the top rung of the common RV range, built for simultaneous shower and kitchen use. This list compares the four 65,000 BTU models that state that output in their own listings.

Each heater was read for door and opening sizes, quoted flow and temperature range, remote or panel controls and listed safety features. Flow figures such as 3.9 GPM depend on temperature rise, so they are reported as listing claims.

Before you buy

What Matters Before You Choose a 65000 Btu RV Tankless Water Heater

Key buying criteria so you get the right fit the first time.

  1. 01

    65,000 BTU and temperature rise

    More BTU supports more rise at higher flows, which helps two taps at once. It matters in cold inlet conditions. Treat GPM claims as dependent on rise.

  2. 02

    Opening size

    12.8 inch and 13 inch openings differ from 18 by 15 inch doors. It matters because forcing the wrong size causes rework. Measure the opening.

  3. 03

    Remote or panel

    A remote lets you adjust inside the RV. It matters for convenience. Check whether it is included.

  4. 04

    Minimum flow

    A burner needs a minimum flow to fire. It matters for low-flow faucets. Look for a stated figure such as 0.74 GPM.

  5. 05

    12V and freeze

    Fans need 12V, and freeze protection needs power and propane. It matters in winter. Check both.

FAQ

Before You Bring One Home

Is 65,000 BTU needed?

It suits families who run two taps at once. Smaller 42,000 BTU units cover one shower at a time.

What mistake do people make?

Trusting headline GPM without temperature rise. Check inlet temperature and your needs.

Is the Baococo 65,000 worth it over the Garvee 65,000?

If you want a remote and high-altitude wording, yes. Otherwise the Garvee 65,000 costs less.

How do I install it?

Shut off propane and power, remove the old unit, connect the water and gas lines and test every joint for leaks. Follow the manufacturer's instructions, and consider a professional for gas work.

How do I winterize it?

Use the freeze protection if the unit is powered and has propane available. Drain the unit and water lines before storing in freezing weather.
