ORBEK RV Tankless Water Heater — High Altitude Ready
Best For: RV travelers who demand reliable hot water at high elevations. The ORBEK model uses a 60,000 BTU propane burner that activates only on hot-water draw, delivering continuous hot water for showers, dishes, and handwashing. This on-demand system aims to reduce propane consumption compared with traditional tank heaters. It is engineered with oxygen-free copper heat exchangers and brushless DC fans to maintain stable temperatures even at mountain elevations. A staged combustion design minimizes cold spots and scalding while conserving propane.
Why selected: High-altitude compatibility and continuous hot water make this a strong pick for travelers crossing plateaus and mountains. The system supports standard RV openings and offers optional door panels for a coordinated look.
Caution: Confirm your existing cutout size before purchase to ensure a proper fit; panel color options are sold separately and not included by default.
RV Tankless Water Heater 12V, 65,000 BTU — Off-Grid Ready
Best For: Off-grid campers who need robust performance with reliable ignition in challenging environments. This model delivers up to 3.9 GPM with quick ignition and automatic flame adjustment. Its leak-resistant design uses a 1.5 kg copper heat exchanger with thicker elbows, supporting operation at altitudes up to 9,840 feet and under cold or low-pressure conditions. Smart ignition reduces propane waste by turning the burner on only when hot water is demanded.
Why selected: The combination of durable construction and altitude resilience makes it a dependable choice for mountain campsites and remote sites where fuel efficiency matters.
Caution: Ensure your water flow and pressure meet the required thresholds for optimal performance; some users may need a compatible mounting and venting setup depending on RV layout.
APUS RV Tankless Water Heater — 68,000 BTU
Best For: RVs that require long showers and steadier hot water, especially where space is at a premium. This unit provides up to 3.9 GPM with a compact footprint (about 14.96″ x 14.96″ x 14.18″) and fits most standard open RV water heater openings. It runs on 12V DC and propane, with remote control for easy temperature management. The device is designed to operate at elevations up to 9,800 feet with intelligent flame adjustment for seasonal changes.
Why selected: Its balance of high BTU, compact size, and remote control makes it practical for mid-sized RVs and travel trailers.
Caution: Space is tight; ensure your compartment can accommodate the specified dimensions and venting requirements.
Xenjum RV Tankless Water Heater — Dual Outlets
Best For: Campers who want hot water accessed at multiple points within the RV. The Xenjum unit offers dual outlets (interior and exterior) with a 65,000 BTU capacity and 3.9 GPM flow. Temperature is adjustable from 95–123°F via remote control, and the unit includes a built-in thermostat for precise control. It is suited for full-time RV setups and off-grid adventures where dependable hot water is essential.
Why selected: Dual outlets provide practical convenience for kitchens, baths, and outdoor washing, while the remote control simplifies temperature tweaks during travel.
Caution: The system relies on 12V/propane power; plan for proper wiring and gas supply, and check compatibility with your RV’s electrical system.
Buying Guide: How To Choose Your RV Water Heater
- Fuel type and availability: Propane is common, but some units may support 12V DC power for off-grid use. Consider your typical travel environment and fuel accessibility.
- BTU and flow rate: Higher BTU (65,000–68,000 BTU) generally means faster hot-water generation, with a flow rate around 3.5–3.9 GPM. Match to your family size and shower frequency.
- Altitude considerations: If you frequent high elevations, choose models advertised for high-altitude performance and anti-freeze protection.
- Open vs. closed compartments: Check the opening size (commonly 15″ x 15″ or 15″ x 18″) and door options. Some kits include lockable or removable access panels.
- Installation footprint: Measure your RV’s heater compartment. Compact models fit tight spaces, but you may trade off some features or outlets.
- Outlets and temperature control: Dual outlets offer versatility for hot-water delivery in different zones. Remote controls simplify temperature management on the go.
- Durability and safety: Look for corrosion-resistant heat exchangers, automatic flame adjustment, and safety features like freeze protection and insulating layers.
Frequently Asked Questions
- Do RV tankless water heaters save propane? Yes. They heat water on demand, so propane is used only when hot water is requested, reducing waste compared with traditional tank heaters.
- Can these heaters operate at high altitude? Many models advertise altitude readiness (up to ~9,800 feet). Verify specifications and install per manufacturer guidelines for best results.
- Is remote control necessary? Remote controls are convenient for adjusting temperature from across the RV, especially when the shower is in a different area.
- What about cold weather protection? Look for automatic seasonal flame adjustments and freeze protection features to prevent damage in winter conditions.
- Do I need a professional to install? Installation often involves gas lines, venting, and electrical connections. A qualified technician is recommended to ensure safety and compliance with codes.
- How do I choose between dual outlets vs. single outlet? Dual outlets offer flexibility for hot water in multiple locations, whereas a single outlet may suffice for smaller RVs or limited space.
