Our Bilge Heaters for Boats are designed to keep your engine space safely above freezing temperatures. And we do so without wasting energy by heating the space to unnecessary levels. It’s why our heaters will turn on at 40 degrees Fahrenheit and turn off at 50 degrees Fahrenheit. Once our bilge heater is triggered, the temperature is maintained at a consistent level. This will keep your bilge space safely in the high 30s to mid-40s despite freezing temperatures outside the bilge. 

Our bilge heaters for boats utilize Positive Temperature Coefficient technology which makes our heaters some of the safest. This PTC technology makes our bilge heaters self-limiting.

Protect Your Boat and Others


You’ll also protect your boat because you won’t be using a lightbulb or portable electric heater, which can cause fire damage. Read our boating horror stories here to read how wrong that can go. Boat U.S. Marine Insurance claims confirm the leading cause of winter vessel fires are unattended portable heaters and overtaxed electrical systems. Portable heaters can easily be tipped over by a wave and start a boat fire. And a boat fire isn’t your only worry. If one boat is on fire, it can easily spread throughout the marina and you’ll be responsible for more damage.
