ORBEK 60,000 BTU RV Tankless Water Heater Review: Retrofits Existing RV Electric and Instantaneous Units

ORBEK 60,000 BTU Heater Overview

ORBEK 60,000 BTU RV Tankless Water Heater provides 60,000 BTU of heat output to maintain consistent flow rates at high altitudes for users requiring high-altitude adaptation.

Endless hot water allows you to shower without timing your usage or worrying about a tank running dry. An rv tankless water heater (recreational vehicle tankless water heater) featuring 12V DC power enables you to run the system from a house battery bank without needing a dedicated AC inverter.

The ORBEK 60,000 BTU Heater achieves this continuous flow through a brushless DC fan system and a 60,000 BTU heat output. It also offers three door options to fit different mounting footprints, such as 15″ x 15″ or 18″ x 18″.

This review is for shoppers looking for a highly-rated unit that fits standard RV requirements. We selected this product for a full review because it was among the most-rated products that pass screening, at most 2 per brand, with 61 buyer ratings. Our research involves analyzing listing data to compare the rv tankless water heater options we evaluated.

The Short Answer on the ORBEK 60,000 BTU Heater

Best for: you need a heater that maintains consistent flow at high elevations while staying within a standard 15″ x 15″ mounting footprint.

The ORBEK 60,000 BTU Heater is a capable choice at the $349.99 price point.

• Pro: 60,000 BTU output provides enough heat to run a shower for 10 minutes without a flame out.
• Pro: The 9,800-foot altitude rating allows for consistent operation in extreme cold or high-altitude environments.
• Pro: Oxygen-free copper heat exchangers improve heat transfer efficiency.
• Con: The lack of a mixing tank means you must manage the temperature balance to avoid scalding.
• Con: The 15″ x 15″ required installation dimension may not fit in smaller cabinetry or tight mounting spaces.

Don’t buy this if: your installation space is smaller than 15″ x 15″ or you require a mixing tank for temperature regulation.

Price assessment: The $349.99 price is fair for a unit that includes CSA Certification and high-altitude adaptation.

Technical Specifications for this Rv Tankless Water Heater

The ORBEK 60,000 BTU Heater provides a 60,000 BTU output, which measures the total heat energy produced per hour.

Before You Buy: Rv Tankless Water Heater Checklist

The first thing to check is your available mounting space, as the required installation dimensions depend on which door size you select.

• ☐ Measure your existing access panel and confirm it matches 15″ x 15″, 15″ x 18″, or 18″ x 18″ — an incorrect size will require you to purchase a separate door or modify your current panel.
• ☐ Verify your water source provides enough pressure for the heater’s capacity — if the shower head’s pressure exceeds the 60,000 BTU output, the unit may shut off or provide cold water.
• ☐ Confirm your RV’s electrical system provides 12V DC power — the unit requires this specific voltage to operate without a dedicated AC inverter.
• ☐ Plan your drainage path for condensate drainage — improper routing leads to internal moisture buildup and premature electronics failure.
• ☐ Check your elevation if traveling in extreme cold — the 60,000 BTU output is the minimum required to maintain consistent flow rates at high altitudes like 9,800 feet.

You should not buy this product if your RV’s door opening is smaller than the 15″ x 15″ minimum requirement.

The ORBEK 60,000 BTU Heater fits into standard RV door sizes, including 15″ x 15″, 15″ x 18″, and 18″ x 18″ options. You can install this unit to replace an existing RV electric water heater or an RV instantaneous water heater because it is designed to retrofit those specific systems. If you are installing it in a high-altitude environment, the 60,000 BTU heat output provides enough energy to maintain hot water at 10,000 ft elevation. For example, this unit can maintain a steady flow of hot water for a 10-minute shower in a mountain campsite without a flame out.

What These Specifications Let You Do

How staged combustion provides a steady flow of hot water

This output allows for a consistent flow of hot water even when the shower head’s pressure is high, which is a common point of failure for lower-capacity units. You can expect a steady stream of hot water for a single shower fixture because the 60,000 BTU rating matches the minimum output required to maintain consistent flow rates in demanding conditions.

Staged combustion technology refers to a system that adjusts the fuel and air mixture to maintain a steady flame. By using this method, the ORBEK 60,000 BTU Heater maintains the heat output needed for endless hot water without the fluctuations that can cause a unit to cycle off. Choosing a unit with lower BTU output than your required flow rate can result in the heater shutting off during use, forcing you to wait for the unit to restart before the water heats up again.

Reliable performance of this Rv Tankless Water Heater at high altitudes

This rating confirms the unit can operate effectively in mountainous regions where thinner air typically makes it difficult for heaters to maintain a consistent flame. You can rely on the heater to provide consistent temperatures during high-elevation travel because its 60,000 BTU output meets the requirements for extreme cold and high-altitude flow consistency.

Operating at high altitudes requires a heater capable of maintaining a stable combustion rate despite lower oxygen levels. Because the ORBEK 60,000 BTU Heater is rated for these conditions, you avoid the risk of the unit failing to ignite or cutting out during a shower in the mountains. If you select a heater without a high altitude rating, you may find the unit cannot provide enough heat to keep the water hot while you are at higher elevations.

Universal Retrofit Compatibility

The ORBEK 60,000 BTU Heater retrofits RV electric water heaters and RV instantaneous water heaters, making it a versatile option for existing setups. It is compatible with other tankless water heater brands, allowing you to integrate it into various plumbing configurations. You can use this unit to upgrade your current system without needing to replace every component, provided your existing plumbing supports the 12V DC input and propane fuel type.

This model offers three door options—15″ x 15″, 15″ x 18″, and 18″ x 18″—to fit different mounting requirements. You must measure your available space and confirm these dimensions before ordering to ensure the unit fits your specific RV layout. Since the required installation dimensions are sold separately, you should verify your mounting surface can accommodate these specific footprints to avoid a situation where the unit arrives but cannot be mounted.

Setting Up This Rv Tankless Water Heater, and What Support Covers

Getting the ORBEK 60,000 BTU Heater Running

You must have a propane fuel source established before the ORBEK 60,000 BTU Heater can produce hot water.

1. Unpack the unit and mount it using a 15″ x 15″, 15″ x 18″, or 18″ x 18″ access panel.
2. Connect the propane supply line and attach a pressure regulator to maintain consistent gas flow to prevent flame outs.
3. Install a condensate drain hose to prevent moisture buildup and internal corrosion.
4. Wire the 12V DC power supply to the unit to enable operation from a house battery bank.
5. Pair the remote controller to adjust the temperature from outside the unit.

Warranty and Support: What to Check

Warranty coverage and support terms vary by seller and country.

• Confirm the CSA Certification status to ensure the unit meets North American safety standards for gas pressure and electrical components.
• Verify the 9,800 feet altitude rating to ensure the heater maintains the required 60,000 BTU output for your specific location.
• Test the remote controller functionality to ensure it communicates with the staged combustion technology.
• Check for any internal moisture in the oxygen-free copper heat exchangers to ensure the unit is sealed correctly.

Turn the unit on and run the water for five minutes to confirm it maintains a steady flow without a flame out as soon as it arrives.

ORBEK 60,000 BTU Heater Buying Questions Answered

How often do I have to do maintenance on the heat exchanger?

The ORBEK 60,000 BTU Heater does not require anode rod replacements, which are sacrificial rods typically used to prevent mineral buildup in water heaters. Because this unit uses oxygen-free copper heat exchangers without that specific component, you can reduce the frequency of internal maintenance compared to standard tank systems.
