Features to know about

Hot Water That Keeps Up with Showers and Sink Use

Short showers and waiting between dishes get old fast, especially when more than one person needs hot water. This tankless propane water heater heats water on demand instead of pulling from a stored tank, with 55,000 Btu of output for RV showers, sinks, and general use. Hot water keeps flowing while water is running, giving you more time at the shower or sink before moving on to the next part of camp life.

Temperature Control from Inside the RV


control panel

Dialing in comfortable water can be frustrating when the heater is outside and the faucet is inside. The included digital remote with LCD display gives you precise temperature adjustment from inside the RV, keeping the main control point where you're actually using the water. You can adjust the heat before or during showers, dishwashing, and sink use from the living space.

Flow Adjustment for Changing Water Temperatures

Incoming water temperature can change from one campground or season to the next, and that can affect how a tankless heater performs. The patented valve automatically adjusts flow based on incoming water temperature for improved efficiency, tying water movement to the conditions feeding the heater. The heater manages flow as water enters, keeping hot water delivery more consistent during normal RV use.

Protection for Common RV Water Heater Problems

Running propane heat and hot water in an RV comes with real concerns, especially in changing weather conditions. This unit includes carbon monoxide and propane leak detection, along with anti-scald and anti-freeze protection to help keep operation safer. These safeguards work in the background while the heater runs, helping protect against gas, temperature, and freezing issues during everyday use.

Compact Retrofit for Replacement Projects

Replacing an older RV water heater often comes down to space, cutouts, and how much rework the install takes. Compact, lightweight construction lets this unit retrofit into most RV cutouts, with 12V DC pulse electronic ignition and forced exhaust for RV operation. During a replacement project, the heater fits into the existing water heater area more easily than a bulky unit that demands a larger opening.
