The HURRICANE ZEPHYR is a compact all-in-one heater that provides space heating and on-demand potable hot water. It is designed for vessels up to 45 feet long, and is ideal for smaller boats with limited space

The HURRICANE ZEPHYR’s diesel boiler provides 33,000 True Output BTU, supplemented by 5,000 BTU of auxiliary heat from a 1500 watt electric element (available in 120 or 240 VAC) which can provide limited hot water and space heating without diesel burner use while under shore power. The HURRICANE ZEPHYR has the ability to heat four separate thermostatically controlled space heating zones. The HURRICANE ZEPHYR is able to provide continuous, on-demand potable 120°F hot water at 1.0 GPM flow rates, and has an internal mixing valve to set hot water temperature preferences. The HURRICANE ZEPHYR’s internal heat exchanger can be used to preheat a vessel’s engine, and waste heat from the engine can be extracted to improve efficiency within the heating system. The HURRICANE ZEPHYR, like all HURRICANE heaters, features a marine-grade stainless steel coolant tank and a marine-grade stainless steel exterior casing.

The HURRICANE ZEPHYR is compatible with the ITRTouch™ remote control interface, an easy to use, state-of-the-art means of controlling, operating and diagnosing the system.

The HURRICANE ZEPHYR, like all HURRICANE heaters, is built on a proprietary low-pressure burner platform that offers safe, quiet, “no-smoke, no-smell,” diesel burner operation, while also improving efficiency and lengthening system maintenance cycles.
