Reliable Warmth Where You Need It Most
Transform chilly workspaces into comfortable zones with this professional-grade compact heater engineered for demanding environments. The powder-coated anthracite steel cabinet delivers rugged durability that outlasts ordinary models, while the internal stainless steel coil element distributes steady warmth across up to 160 square feet. A high-performance circulation system maintains consistent temperatures throughout your space, and the IPX4 moisture rating means you can confidently deploy it in humid conditions—perfect for plant rooms, workshops, or garages where dampness is part of the job. Dial-controlled temperature adjustment from -58°F to 210°F puts you in charge, season after season.
Why You Need This
- Built-In Safety Shutoff: Automatic thermal cutoff activates if internal temps climb too high—just unplug, wait 10 minutes, and you're ready to go again.
- Splash-Proof Design: IPX4 certification guards against moisture exposure, making it the smart pick for greenhouses, barns, and grow spaces.
- Wide Temperature Range: Dial anywhere from sub-zero to over 200°F to match your exact comfort or cultivation needs.
- Exceptional Air Movement: Integrated fan circulates heated air evenly, eliminating cold pockets in corners and behind benches.
- Metal Construction: Heavy-duty steel housing resists knocks, weather, and daily wear far better than flimsy alternatives.
- One-Year Assurance: Factory-backed warranty and responsive customer support give you peace of mind from day one.

At 12.4 inches long and 8.3 inches wide, it fits neatly into tight corners without sacrificing output.
