Xtreme Heaters: The Best, One-of-a-Kind Bilge Heaters on the Market
When it comes to protecting your boat during cold weather, no other bilge heater on the market compares to Xtreme Heaters. From our first heater built twenty years ago, engineered with the latest technology and built to withstand the harshest marine environments, Xtreme Heaters continues to refine and raise the bar for reliability, safety, and performance. Here’s why Xtreme Heaters are the best choice for your boat:
-
Superior Design for Marine Environment
Xtreme Heaters are engineered to thrive in the harshest marine conditions. Every component, designed exclusively by Xtreme, is built to withstand the rigors of boat engine compartments. These heaters are fully corrosion-resistant and specifically designed to handle extreme humidity, saltwater exposure, gas, oil, dust, and the constant vibrations found in marine environments. From the tough outer casing to the high-performance internal parts, Xtreme Heaters are built for uncompromising durability and reliability.
We don’t just meet marine industry standards—we exceed them. Each heater undergoes rigorous testing to ensure it performs in even the roughest conditions, proving time and again that Xtreme Heaters are built to last.
-
Automatic Thermostat Control
The built-in automatic thermostat is one of the key features that sets Xtreme Heaters apart. It activates the heater when the temperature drops to 40°F and shuts it off once the temperature reaches 55°F, ensuring that your engine compartment stays within a safe range to prevent freezing without wasting energy. This smart control ensures that your boat is always protected, even when you’re not around.
-
Safety Features that Go Beyond the Standard
Xtreme Heaters are equipped with numerous safety features to ensure peace of mind. Each heater is ignition-protected, meeting strict marine safety standards including US Coast Guard standards for use in engine spaces. Our heaters have passed rigorous military spec testing for vibration, as well as extreme high and low temperature conditions. We go to great lengths to test and validate our products, ensuring that Xtreme Heaters deliver the highest grade of equipment available. No other heater on the market has been more extensively tested or has the proven 20-year track record that Xtreme Heaters do.
-
Energy-Efficient Performance
Energy efficiency is designed into Xtreme Heaters. The automatic thermostat ensures that the heater only operates when necessary, conserving energy and reducing power consumption. Our heaters use PTC (Positive Temperature Coefficient) heating elements, which are the most energy-efficient source for heating due to their self-regulating properties. What does this mean for you, the consumer? It means that as our custom element warms up it tapers down its energy use while continuing to do its job, using less energy while still performing. This translates into cost savings for you over time, as the heater automatically adjusts its energy usage to meet the needs of your boat’s engine compartment.
Additionally, the PTC element allows us to set a preset temperature range so that the heater never exceeds a safe temperature for use in areas with explosive fumes (250°C), making it extremely safe to use around the potential gas fumes in and engine space.

Advanced Electronics Designed for Military and Medical-Grade Performance
Xtreme Heaters’ electronics are engineered to the highest standards, meeting military and medical-grade quality. These electronics feature a built-in timer to run the fan and reset the heater to ambient temperatures, ensuring optimal functionality. A tri-colored LED indicator allows you to know the heater's status at a glance:
- Green: Standby mode, ready to work.
- Orange: Cool-down mode.
- Red: Heating mode.
-
True Forced Air Heating for Maximum Effectiveness
One of the standout features of Xtreme Heaters is the true forced air heating system, which circulates heat evenly throughout the engine room. This ensures that all critical components are protected, not just those closest to the heater. Forced air heating is the most efficient way to distribute warmth, and we use a custom specked, waterproof 58 CFM fan with high back pressure rating to ensure consistent airflow across the heating elements.
The fan is IP68-rated, meaning it is fully protected against dust and can withstand continuous immersion in water without harmful effects, ensuring long-lasting performance even in harsh marine environments.
Additionally, the heater can be mounted in any orientation—upside down, vertically, or horizontally—providing maximum flexibility for installation, no matter the size or layout of your engine room.
-
Anodized Case and Sealed Heating Elements for Corrosion Protection
To withstand the toughest marine environments, our heaters’ anodized aluminum case and sealed heating elements provide superior protection from corrosion, particularly in salty and humid conditions. These features also protect the heater from gas, oil, and other contaminants that may be present in the engine compartment. We have seen Xtreme Heaters in service for up to 20 years with no signs of corrosion or rust. Built to last the life of your boat, this rugged design ensures that your heater continues to perform for years, making it one of the most durable options on the market. -
Compact, Powerful, and Easy to Install
Xtreme Heaters pack a powerful punch despite their compact size, making them ideal for tight engine compartments in boats of all sizes—from smaller runabouts to large yachts with complex systems. With models ranging from 400W to 800W, they offer flexible options for various boat setups. Their compact design allows for multiple installation configurations, ensuring that space constraints are never an issue.Installing an Xtreme Heater is as straightforward as it gets. Whether you’re a DIY enthusiast or prefer professional installation, the included mounting hardware and simple design make the process quick and easy. With just a Phillips screwdriver, you can have your heater installed in a few steps. Simply plug it in, and it’s fully automatic—ready to protect your boat. For a more permanent solution, the heater can also be hard-wired into your boat’s fuse panel by a local expert. The power cord is rated for use on a boat and cutting the plug off to wire it in will not void your warranty.
