Stay Warm This Winter with Cast Iron Grid Heaters

As the seasons shift and the air turns crisp, now is the time for industrial facilities to get ahead of the cold. At Cast Iron Heaters, we’ve spent over 90 years building heaters that deliver reliable, efficient warmth to warehouses, factories, hangars, and more.

Our 420, 425, 525, and 625 Series grid heaters are built from one-piece cast iron finned radiators—no welds, no seams, and no leaks. This rugged design stores and releases heat evenly, keeping large spaces consistently comfortable while minimizing maintenance and operating costs.

When winter hits, a warm workspace isn’t just about comfort—it’s about keeping your team productive, protecting equipment from the chill, and ensuring operations run smoothly. Installing or upgrading your heating system now means you’ll be ready before the first frost arrives.

Durable. Reliable. Built for the cold. Make this winter your most comfortable and efficient yet with a Cast Iron Grid Heater.
