Drolet is proud to present the HeatMax II, a completely re-engineered high efficiency wood furnace that meets the new EPA (CSA B415.1-10) clean-air standards. This enhanced furnace will provide considerable energy savings over a conventional wood furnace, using up to 30% less wood for the same amount of heat. The HeatMax II is equipped with an adjustable rectangular hot air plenum that can accommodate 6 to 10, 6-inch diameter heating ducts. This adjustable plenum provides greater flexibility for an easier installation. Another key feature is an electronic probe, which measures the temperature in the plenum and varies the blower speed accordingly, assuring maximum comfort. The Drolet HeatMax II: Sophisticated comfort control!
