Endless Hot Water Supply — The heat output is enough to supply an entire RV with endless hot water, like other higher BTU models, and also save propane. The KINGRVER tankless RV water heater effortlessly supports multiple hot showers and dishwashing without preheating. The Adjustable Temperature ranges from 95°F-123°F.
High altitude Application — The KINGRVER RV on-demand Water Heater can operate at above 5000 ft high altitudes. It accommodates the low-oxygen conditions experienced at such elevations. Staged combustion technology modulates the flame intelligently based on seasonal factors, keeping water temperatures steady while reserving limited propane for travelers navigating the region's elevated terrain by caravan. The combined effects deliver an unprecedented high-altitude travel experience.
Built-In Safety Measures — A forced exhaust fan ensures stable combustion. A 150PSI pressure relief valve ensures safety. Plus, automatic gas shut-off protects against accidental flame loss. An anti-freeze device protects against low temperatures that could cause freezing. It automatically activates when sensing below 42.8°F, keeping water thawed. Safety and reliability are built in from the top down.
Certified Quality and Expert Support — The KINGRVER RV water heater is CSA-certified and has 2 Years of service. We have a 7x24 professional Technical Support team.
