WATTCO™ large tank heaters consist of three specific heating systems, open coil element pipe insert heaters, single immersion heaters, and flexible tank heaters that can be used in large storage tanks. These systems can be installed in steel, concrete, or fiberglass above or below ground tanks.

WATTCO™ large tank heaters are the best solution for applications that require little or no manual attention and provide small amounts of heat to maintain temperature levels in the tank during the daytime and high performance during nighttime.
