All models feature a comprehensive six-layer safety system including flame failure protection (automatic gas cut-off), overheat protection, anti-freeze protection, pressure relief valve, automatic gas shut-off, and Low NOx emission control – ensuring safe operation across all usage scenarios.
We offer a wide range of capacities from 6L to 24L, covering applications from single-point kitchen use to whole-house supply. All models support Natural Gas, LPG, and Propane – providing flexibility for different regional gas infrastructures.
Check in this order:
1.Propane supply – Check if the tank has gas and the valve is fully open
2.Power supply – Check if 12V power is available and fuses are intact
3.Air intake and exhaust vents – Ensure they are not blocked
Yes. Annual descaling is recommended. In hard water areas, mineral deposits can accumulate inside the heat exchanger, affecting heating efficiency and equipment lifespan. Unlike tank-type heaters, tankless units do not require anode rod replacement.
Although tankless heaters have no storage tank, they still retain a small amount of water (about 1 liter). Winterization steps:
1.Turn off gas and power
2.Disconnect water source and drain the system
3.Pump non-toxic RV antifreeze through the system
Winterization steps may vary by brand and model – always refer to the specific product manual.
If the campground's city water connection pressure is too low, it is recommended to fill the fresh water tank and use the RV's internal water pump to provide stable water pressure.
This is usually caused by mixing cold water at the tap, or by others using a faucet or flushing the toilet while you are showering. Tankless systems are sensitive to changes in water flow – stability depends on a steady flow rate.
The correct method is: use only the hot water valve at full flow, then adjust the temperature via the control panel – rather than mixing in cold water. If you mix in cold water at the tap, it reduces the water flow through the heater, which may cause the burner to shut off or result in unstable water temperatures.
Yes. The control system, ignition device, and safety switches all require 12V DC power to function. If the RV battery is low or voltage is insufficient, the water heater may not ignite or operate properly.
Yes, the vast majority of RV tankless water heaters use propane as their sole heating source. Propane is much more efficient at providing rapid, high-heat output compared to electricity – and electric heating would consume precious RV battery power reserves.
