Suburban ST-60 Tankless RV Water Heater 5482A – 60,000 BTU
The Suburban ST-60 5482A/ 5382A Tankless RV Water Heater provides continuous hot water on demand for RVs without relying on a traditional storage tank. With a powerful 60,000 BTU LP gas burner, the ST-60 is designed for higher hot-water demand while still heating water only when it is needed.
The ST-60 includes a wall-mounted digital control center that allows the user to set and manage water temperature from inside the RV. Suburban designed the ST-42 and ST-60 as compact RV-specific tankless systems with built-in safety and protection features.
Continuous Hot Water On Demand
Unlike a conventional RV water heater that stores a limited amount of heated water, the Suburban ST-60 heats water as it flows through the unit.
The burner operates only when there is a demand for hot water, helping reduce unnecessary propane use while providing an effectively continuous supply of hot water for showers, sinks, and other RV fixtures.
Powerful 60,000 BTU Performance
The ST-60 is rated at 60,000 BTU per hour, giving it considerably more heating capacity than the 42,000 BTU ST-42.
This higher output makes the ST-60 a strong choice for RV owners who want:
-
Faster temperature rise
-
Better performance during higher water-flow demand
-
More consistent hot-water output
-
Greater heating capacity in colder incoming-water conditions
-
Continuous hot water without tank recovery time
Digital Temperature Control
The digital wall-mounted control center is included with the ST-60 and allows the user to control the water heater from inside the RV.
This eliminates the need to rely solely on mixing hot and cold water to reach the desired shower or faucet temperature.
Built-In Safety & Protection Features
The Suburban ST-series water heaters are designed with multiple electronic monitoring and protection systems, including safety controls intended to monitor burner operation, temperature, airflow, voltage, and other operating conditions.
The ST-series also incorporates freeze-protection functionality for added protection during cold-weather operation.
Designed for RV Tankless Water Heater Applications
The ST-60 measures approximately:
-
Width: 12-3/4"
-
Height: 12-1/2"
-
Depth: 13"
Suburban lists the ST-42 and ST-60 with the same compact dimensions, allowing them to fit many RV water-heater installations without requiring the space of a larger residential-style tankless unit.
Always verify the existing RV sidewall opening, plumbing, LP gas connection, and electrical requirements before replacing another water heater.
Exterior Access Door
The exterior access door is sold separately.
Suburban lists the following ST-series doors:

ST-60 vs. ST-42
The primary difference between the two ST-series water heaters is heating capacity:
ST-42: 42,000 BTU
ST-60: 60,000 BTU
Both models use the same general compact ST-series footprint, but the ST-60 provides approximately 43% more maximum burner output than the ST-42.
For RV owners expecting heavier hot-water use or colder inlet-water temperatures, the ST-60 offers the greater heating capacity of the two.
Replacement Parts Availability
The ST-60 shares several service components with the ST-42, while certain major electronic components are model-specific.
Common ST-42/ST-60 shared parts include components such as the 233665 water flow sensor and 233658 airflow switch.
The ST-60 uses its own 521339 control board, which replaces the older 233666 board and is specifically intended for the ST-60.
