The full line of L.B. White forced air greenhouse heating solutions are manufactured to ensure heat goes into the greenhouse, unlike indirect-fired heaters that lose 20% of heat out of the chimney. L.B. White’s Therma Grow™ and Guardian® forced air direct-fired greenhouse heating systems are the new standard for efficient, reliable greenhouse heaters.
L.B. White provides more than a great greenhouse furnace—our technical experts and customer service teams provide expertise and support to create complete heating solutions that protect L.B. White greenhouse heater investments.
