Xenjum RV Tankless Water Heater 65000 BTU, Dual Outlets and Controller
Product description
RV owners who want hot water on demand can use this Xenjum tankless heater for showers, dishes and everyday routines. It delivers up to 65,000 BTU and a maximum flow rate of 3.9 GPM. Since it ignites when a tap is turned on, it heats water when needed rather than keeping a tank of water hot between uses. Dual outlets serve indoor and outdoor hot-water needs from one unit.

The controller lets you adjust the temperature from 95–123°F, while the built-in thermostat is described as maintaining consistent water temperature. Automatic seasonal flame adjustment removes the need to switch manually between winter and summer modes. For day-to-day use, that means straightforward temperature control as needs change between a shower, kitchen sink or outdoor wash-up.

What it works with
The dual outlets are intended to supply hot water inside the RV, including the bathroom and kitchen, as well as outside for camping tasks such as washing pets. It is designed for RVs with a 13 x 13 inch opening and a 15 x 15 inch door. The stated installation connections are 12V DC power and standard NPT fittings, making those practical details to match to the vehicle and plumbing setup.



For a full-time RV, the on-demand design suits regular routines without a storage tank to heat. On a camping trip, the exterior outlet gives you another place to use hot water without relying only on the indoor shower. Compared with choosing a heater centred on a single outlet, this setup is aimed at serving both indoor and outdoor needs from one unit.
Usage tips

Use the controller to set the water temperature for the task at hand, then turn on the tap to call for hot water. The unit is designed to adjust its flame automatically with the season, and its stated protections include anti-freezing and dry-combustion protection. For installation, match the opening, door dimensions, 12V DC supply and NPT fittings to your RV. The included installation manual and controller support setup and everyday operation. A child-safe lock and keys are also included.


What to clarify

Can it supply hot water indoors and outdoors? Yes. It has dual outlets for indoor RV use, such as the bathroom and kitchen, and outdoor activities such as pet washing.
What comes with the heater? The listed components are the water heater unit, controller, shower head set, child-safe keys and installation manual.

Is support included? The product listing states a 24-month warranty and technical support. Check the warranty terms for the coverage and service process that apply to your purchase.
Is it worth it?
For RV owners looking to combine on-demand hot water with more than one point of use, the Xenjum brings a 3.9 GPM maximum flow rate, temperature control and dual outlets into a wall-mounted unit. Its indoor and outdoor applications make it particularly suited to RV routines that include both showers and tasks outside the vehicle.
