Xtreme Bilge heaters Suitable for most boats up to 24' Length single engine.

The Xtreme 400w small Bilge Heaters are an ideal solution for maintaining warmth in smaller vessels, such as runabouts, ski boats, fishing boats, sail boats, and pocket cruisers. These heaters are designed to provide reliable freeze protection in confined areas, ensuring that your boat remains operational even in harsh winter conditions.

In addition to engine compartments, the 400W Xtreme Heater also works well in smaller spaces, such as bathrooms, under kitchen cabinets, and around freshwater lines and AC units, ensuring these areas are protected from freezing. If your boat is stored on a lift or trailer, we recommend choosing a heater one size larger than the suggested model or a second heater for optimal performance.

  • True Forced Air Heating circulates air more effectively and heats more evenly for more accurate climate control.
  • Automatic Thermostat turns the heater on at 40°F and off at 55°F +/-3° - the tightest tolerance available.
  • Failsafe Design cannot overheat. Heating technology is dynamic and self-regulating.
  • High Efficiency Xtreme produces heat faster, circulates more air and shuts off earlier.
  • Pre-wired 15ft marine rated power cord with 110V 3 prong plug eases installation.
  • Maximum Life - Designed for durability and reliability.
  • Complete Protection: Fully anodized inside and out.
  • Small Footprint
  • Certified and Independently Tested 

As product and industry experts, our goal for the Xtreme Heater was to produce a highly safe, dependable, and efficient option on the market. With our heaters, you can confidently stay on the water for extended periods.

If your boat is docked on a lift or trailer, you may need to consider increasing the wattage of the heater up one level to compensate for heat loss. Make sure to cover the fresh air vents to prevent air from escaping and the cold from coming in, resulting in a more efficient heater and saving you money.

Because boats vary in materials, insulation, and design, it's essential to carefully assess your specific needs and climate to determine the most suitable heater. In some cases, depending on the size and configuration of your boat, more than one heater may be necessary to ensure adequate protection. The compact size and efficient performance of Xtreme Heaters make them a perfect choice for these smaller spaces​​.

Houseboat engine room heater

I have used this for 3 years when I experienced a failure. I ordered a replacement and asked if they could repair my old one as a spare. They stood behind it and sent me a brand new unit well after the warranty expired. In today’s world it’s hard to find good products and harder to find companies willing to go above and beyond Xtreme did in my case 100%.

We have build in bilge heaters in our 46' Chris Craft but this was the boose we needed for low temps

I have temperature sensors in the bilge that stayed above freezing in zero degree f weather but our domestic water pump and the ac pumps froze during one very cold snap. By adding this little plug in heater the temperatures stayed safely warm and gave me peace of mind. It moves just enough air to circulate the heat. I'm very pleased.
