Xtreme Heaters XSHEAT-250 Compact Compartment Heater 250W 120V Freeze Protection

The Xtreme Heaters XSHEAT-250 is a 250W, 120V forced-air enclosure heater engineered for dependable freeze protection in small, sealed compartments. Designed for spaces up to approximately 50 cubic feet, it delivers targeted heating where larger units simply won't fit.

A built-in fan circulates 34 CFM of warm air throughout the enclosure, eliminating cold spots and protecting plumbing, batteries, electronics, and other sensitive equipment from freezing temperatures. The self-regulating PTC (Positive Temperature Coefficient) heating element is fail-safe by design — it cannot overheat, making it suitable for unattended, continuous-duty operation.

Key Features:

• Automatic Thermostat: Cycles on at 40°F and off at 55°F (±3°F tolerance) to maintain above-freezing temps while minimizing energy use
• True Forced-Air Heating: 34 CFM fan delivers even air circulation to reduce cold pockets in tight enclosures
• Fail-Safe PTC Technology: Self-regulating heating element prevents overheating during continuous-duty use
• IP68 Rated: Fully sealed heater and fan with fully anodized housing inside and out — resistant to dust, moisture, and vibration
• Ignition Protected: Tested to USCG 33 CFR 183.410 and SAE J1171 standards for safe use in fuel-vapor-prone environments
• Mil-Spec Tested: MIL-STD-810E Method 514.4 tested for vibration, humidity, and high/low temperature extremes
• ASSE-1060 Certified: Independently tested and certified for enclosure heating applications
• Flexible Mounting: Can be installed horizontally, vertically, or upside down to fit tight compartments
• 5-Year Warranty: Best-in-class coverage backed by U.S.-based customer support

Ideal applications include jet ski compartments, RV wet bays, battery boxes, valve boxes, small pump/water spaces, overlander van compartments, electronics cabinets, NEMA enclosures, and small air compressor enclosures. Note: This unit is sized for small, sealed enclosures only — not intended for large engine rooms or drafty open spaces. Step up to a higher-wattage Xtreme Heaters model for larger applications.
