Product Description

12V Caravan Tankless RV Gas Water Heater 42,000BTU For Trailers

Features:

1- Wide 12V voltage compatibility ensures stable operation for all RV types.

2- Compatible with common LPG gas sources for convenient outdoor energy supply.

3- Intelligent self-check system automatically detects faults and gives reminders.

4- Digital display shows real-time water temperature for precise adjustment.

5- Multi-level temperature settings meet showering, washing and cleaning needs.

6- Temperature memory function saves preferred settings for next use.

7- Anti-scald water output prevents high-temperature scalds for safe family use.

8- Built-in pressure relief valve protects pipes from overpressure damage.

Equipped with a high-efficiency rapid heating core, this RV water heater abandons the traditional long preheating mode and heats up quickly after startup. It adapts to temporary water scenarios such as RV dwelling and outdoor camping, providing instant hot water to solve the problem of outdoor cold water use and greatly improve the comfort of mobile living.

Advantage:

It supports ultra-wide temperature adjustment to adapt to seasonal water needs. It provides comfortable warm water to prevent scalding in summer, fast high-temperature heating for cold resistance in winter, and balanced warm water for daily use in spring and autumn, covering full-year RV living water scenarios with full-range temperature control.

Equipped with low water pressure start technology, it starts heating normally at a low flow of 0.5GPM, adapting to unstable water pressure of RV water tanks and outdoor water sources. It works normally in low-pressure environments such as mountainous and suburban areas, solving the problem of heating failure caused by low water pressure in complex outdoor scenarios.

① Door Appearance Customization: Custom Access Doors for Different RV Models. To meet the requirements of various RV manufacturers and aftermarket distributors, we provide fully customizable access doors, including dimensions, colors, ventilation grille design, logo printing and branding, lock and latch configurations, and private labeling options.

② Custom Internal Structure Design: It can equipped with a built-in water pump, which enhances the water circulation function, allowing hot water to continuously flow through the RV piping. Just press the button and all the faucets will immediately dispense hot water - there is no need to wait or waste cold water. It can also be equipped with a water filter, enabling people to obtain cleaner hot water, healthier bathing, especially suitable for those with sensitive skin. At the same time, we can also install a constant-temperature water storage tank, which enables us to say goodbye to sudden changes in water temperature - every time we use water, it is comfortable, stable, safe and reliable.

③ Custom Burner: High efficiency (90%+) – Uses less propane, longer off‑grid trips. Wide flame modulation – Stable water temperature even when flow or inlet temperature changes. Low flow activation – Works with water‑saving RV shower heads.Wind & altitude resistant – Won't blow out; performs up to 9,800m. Quiet combustion – No roaring noise, RV‑friendly. Vibration‑proof – Stays reliable on bumpy roads. Instant ignition – Hot water on demand, no waiting. “More heat. Less propane. Zero frustration.”

④ Remote Controller Customization: Instant Customize your own exclusive remote control. The new generation remote control enables you to better monitor the product status. ·

⑤ Heat Exchanger Customization: Heat exchangers have always been the core component of household gas water heaters and recreational vehicle gas water heaters. The material and quality of the heat exchanger determine the lifespan and safety of the entire gas water heater. Many low-cost modified vehicles use aluminum water tanks to save costs, but they have short lifespans and are prone to leakage. (Our factory) uses high-purity oxygen-free copper which made through an integrated welding process combined with high-precision interfaces, ensuring that the core components possess extremely strong structural toughness and seismic resistance. Even when driven on bumpy roads such as gravel roads or unpaved surfaces for a long time, the components remain firmly and tightly attached, completely preventing loosening and leakage caused by vibration.

⑥ Precision Temperature Control PCB: The intelligent control PCB of the water heater has a decisive influence on the fluctuation of water temperature. Our RV water heater control board uses a smart PID algorithm to maintain water temperature within ±1℃, even when campground water pressure fluctuates or multiple taps are opened. No more scalding or freezing showers. Designed for the RV environment: wide voltage 10-17.5V DC with overload protection, conformal coated and vibration-proofed for bumpy roads and high humidity. Ultra-low standby power (<0.5W) saves your battery. Self-diagnosis with digital error codes makes troubleshooting easy. Automotive-grade components work from -40℃ to +85℃. Perfect for RV, camper, and marine gas water heaters. Upgrade your comfort on the road.

⑦ DC Variable Speed Fan Motor Customization: During produce, we using the DC brushless variable speed fan that automatically adjusts speed based on combustion demand. Unlike fixed-speed AC fans, it runs only as fast as needed, cutting power consumption by up to 40% and saving your RV battery. The soft-start technology makes operation whisper-quiet – no more loud roaring. It also maintains optimal air-fuel ratio even in strong outdoor winds or at high altitudes, preventing flame blowout and CO emission. With sealed bearings and vibration-resistant design, it lasts through bumpy roads. Experience faster heating, lower noise, and safer combustion for your off-grid adventures. Smart, Quiet & Efficient.

⑧ 500ml Temperature-Controlled Container: If you want, we can integrates a 500ml mini buffer tank that stores a small reserve of heated water. When cold water enters the system, the stored warm water instantly blends with it, neutralizing temperature dips and delivering a more consistent outlet temperature. This reduces the need to run water while waiting for it to reheat, saving precious fresh water and energy. The compact tank also minimizes thermal shocks to the heat exchanger, extending component life. Ideal for boondocking and family travel, it ensures every drop of hot water is used efficiently – no more sudden cool surprises, just steady, comfortable flow throughout your shower or dishwashing routine. Smooth Temperature Transition, Less Water Waste.

⑨ Custom Front Outlet: If you need, we can feature an additional front-facing outlet, allowing you to draw hot water directly from the front of the unit without going inside the RV. Perfect for outdoor showers, washing muddy gear, rinsing dishes at the campsite, or filling a bucket for pet cleaning. The separate outlet gives you more flexibility – no need to run long hoses or open interior faucets. Ideal for boondockers, overlanders, and family campers who spend most of their time outside. Built with durable brass threads and a one-way check valve to prevent backflow.
