2020 L.B. White Greenhouse Guardian® Forced Air Heaters 250

The Guardian®'s time proven direct-fired design was specifically designed to protect your investment when the weather turns cold.

Although the Therma Grow™ Family of heaters works best for greenhouses as they are designed specifically for horticulture environments and are the cleanest burning direct-fired heater available today, an outdoor mounted Guardian® might be a good alternative when growing less sensitive plants.

Guardian®s provide consistent, dependable heat for a wide range of greenhouse environments.

L.B. White is the pioneer in direct fired heaters and with 50 years of perfecting every aspect of our design which has led to our reputation for reliability, durability and serviceability.

Our exclusive Service Saver™ monitoring simplifies trouble shooting and helps you get your heater back up and running faster and easier.

When the fate of your plants is at stake… you want the rising star in greenhouse heating protecting your investment… L.B White.
