BUILT to be the BEST Period! American Owned
Whether you’re navigating the open water, hitting the road in your RV, or safeguarding critical industrial equipment, cold weather shouldn’t stop your adventures or operations. Xtreme Heaters delivers the ultimate solution for freeze protection, engineered to keep your boat’s engine, RV’s vital systems, or industrial enclosures safe in even the harshest conditions. Don’t let freezing temperatures catch you off guard—discover why Xtreme Heaters is the trusted choice across marine, RV, and industrial applications.
Freezing temperatures can wreak havoc on critical systems, whether it’s your boat’s engine, your RV’s plumbing and batteries, or sensitive industrial equipment like backflow prevention enclosures or electronic cabinets. A sudden cold snap can lead to costly repairs. Cracked engine blocks, burst water lines, or damaged electronics can cost thousands. Instead of relying on risky alternatives like household space heaters or light bulbs, Xtreme Heaters offers purpose-built solutions designed for safety, efficiency, and reliability. From extending your boating season to keeping your RV ready for winter storage or ensuring uninterrupted industrial operations, Xtreme Heaters has you covered.
At Xtreme Heaters, we’re driven by a singular mission: to deliver the safest, most reliable, and efficient heating solutions for marine, RV, and industrial environments. Since 2004, we’ve set the standard for freeze protection, earning the trust of boaters, RV enthusiasts, and industrial professionals worldwide. Our heaters are engineered to protect critical systems—boat engines, RV plumbing and lithium batteries, industrial enclosures—ensuring your adventures or operations continue year-round.
Xtreme Heaters are designed with safety first. Our marine and RV heaters meet or exceed strict standards, including U.S. Coast Guard and ABYC requirements, and have been rigorously tested to military specifications (Mil-Spec) for vibration, humidity, and extreme temperatures. Industrial applications benefit from the same robust safety features, ensuring protection in confined spaces with potential gas or oil exposure. Our Positive Temperature Coefficient (PTC) technology ensures the heater cannot overheat, providing peace of mind whether you’re on the water, on the road, or at a worksite.
Our heaters use advanced PTC technology, which self-regulates to maintain optimal temperatures while minimizing energy consumption. This means faster heating, better air circulation, and earlier shut-off, saving you money on power bills. For RV owners, this is critical for boondocking or winter storage, while industrial users benefit from reliable performance without excessive energy costs. The automatic thermostat activates at 40°F and deactivates at 55°F (±3°F), offering the tightest temperature control in the industry.
Built to withstand the toughest environments, Xtreme Heaters feature fully anodized aluminum casings, sealed electronics, and marine-rated power cords. Whether facing saltwater exposure on a boat, road vibrations in an RV, or dust and moisture in industrial settings, our heaters are designed for maximum durability. Customers across all markets report years of flawless performance, with some relying on their Xtreme Heaters for over a decade.
Xtreme Heaters are engineered for flexibility. Their compact size fits tight spaces like boat bilges, RV battery compartments, or industrial enclosures. With versatile mounting options—including vertical, horizontal, or upside-down installation—and optional quick-release brackets, our heaters are easy to install and remove seasonally without tools. Available in 400W, 600W, and 800W models, you can mix and match to suit your specific needs, whether heating a small boat bilge, an RV basement, or an industrial backflow enclosure.
Don’t let cold weather halt your adventures or operations. Whether you’re a boater refusing to end the season, an RV enthusiast preparing for winter, or an industrial professional protecting critical equipment, Xtreme Heaters offers the perfect solution.
