Freeze Protection

Boat owners must winterize engines and freshwater systems, especially when boats are stored ashore. In deep freeze states, boats stored ashore must be winterized earlier than boats stored in the water. When the temperature falls below freezing, if there is water inside your engine, exhaust risers or heat exchanger(s), the result can be a cracked block or housing and a repair bill that runs into the thousands. It is easy enough to prevent this unhappy circumstance by winterizing a boat engine properly at the end of the boating season.

This is why we make the Xtreme Heater. Our heaters are engineered specifically to provide reliable, efficient freeze protection, ensuring your boat’s critical components stay above freezing even in the harshest conditions. They are designed to maintain a safe temperature in your engine compartment and other critical spaces, automatically activating when temperatures dip below 40°F and shutting off once they reach around 50°F. This feature prevents freezing while avoiding unnecessary energy use, keeping your boat protected without the risk of overheating.

Key benefits of the Xtreme Heater include:

• Prevents Costly Damage: By keeping your engine, batteries, and pumps from freezing, Xtreme Heaters help prevent expensive repairs and replacements caused by cracked blocks, risers, manifolds or housings.
• Energy-Efficient Operation: The built-in thermostat ensures the heater only runs when needed, reducing energy consumption while still providing robust protection.
• Safe and Reliable: Xtreme Heaters are safe for unattended use, making them a convenient addition to any winterization plan. They also help prevent mold and mildew growth, maintaining a dry and protected environment inside your boat.
• Flexible Protection: Whether you fully winterize your boat or need protection during sudden cold snaps, Xtreme Heaters offer peace of mind by targeting areas where antifreeze may miss, ensuring no hidden pockets of water freeze and expand.

These heaters are a simple yet powerful solution to keep your boat safe from the dangers of freezing temperatures, helping you avoid the stress and expense of winter damage.

Fire Hazard Prevention

In the winter, portable heaters are the wrong way to keep your boat from freeze damage. Boat U.S. marine insurance claims files confirm the assessment that the leading causes of winter vessel fires are unattended portable heaters and overtaxed electrical systems. Unattended heaters are easily tipped over by 

A couple of January’s ago, a vintage 47-foot Chris Craft caught fire and burned to the waterline at a marina in Gloucester Point, VA. A subsequent investigation found that three portable electric heaters had been left aboard while the boat was unattended. Luckily, the fire occurred in daylight and was discovered before any nearby boats were damaged. That isn’t always the case; there have been instances where entire marinas–including dozens of boats–were devastated after a single boat caught fire.
