Haoguo 900W Boat Bilge Heater | Self-Regulating PTC for Winter Storage

The Haoguo 900W Boat Bilge Heater is built to protect your boat’s vital systems during cold storage and winter months. Thoughtfully designed to fit tight spaces, this compact heater brings targeted warmth where you need it most—helping to keep bilge pumps, engine components, and batteries dry and ready for action. While you can’t predict every condition, you can give your vessel a smart heating option that reduces the risk of cold-related disruption.

Smart, self-regulating warmth

This unit uses a self-regulating PTC ceramic element that activates at 40°F and turns off at 50°F. The result is safe, stable heat that adapts to ambient temperature without overshooting, suitable for areas up to about 800 cubic feet. The system runs quietly and maintains a comfortable baseline warmth, helping to preserve critical boat systems through chilly nights and gusty winds.

• Prevents freeze-related damage to bilge pumps, engine parts, and batteries by maintaining a warmer microclimate.
• Auto-regulating operation provides consistent warmth without manual adjustments or constant monitoring.
• Designed for spaces up to 800 cu ft, balancing performance and energy efficiency.
• Built-in 15A overcurrent protection helps guard against abnormal electrical conditions.
• Tri-color status indicators show standby, heating, and cooling at a glance for quick checks.

Rugged, marine-ready design

Engineered for harsh marine environments, the heater features a rust-resistant painted metal housing, a waterproof fan, and protective coatings for internal electronics. These elements resist moisture, salt, and dust exposure, so you can rely on steady warmth in demanding conditions without frequent maintenance.

• Compact footprint fits narrow engine compartments or tight bilge areas.
• Marine-grade construction withstands moisture and salt without compromising performance.
• Waterproof fan helps maintain airflow while protecting critical components.

Versatile placement and use cases

Beyond the bilge, this heater is well suited for a range of spaces where steady warmth matters—boat cabins, engine bays, well houses, RV compartments, and other vessels. Its compact design and protective features make it a practical choice for seasonal storage or quick winter prep.
