Mr. Jean-Pierre Paré owner of Diven Farm located in Compton in the Eastern Townships uses a Blue Sky energy generator and Dragon Vert heating units to heat his farm buildings. When it comes time to dry his grain, he adapts this same equipment to a grain dryer that runs on propane gas. After taking into account the cost associated with wood and labor Mr. Paré confirms that in 2013 his Sequoia system afforded him a savings of 5.00 $ of propane / ton. Since he dries between 2 000 to 2 500 tons of corn annually, this technique allows him to save 10 000 $ to 12 500 $ in a single drying season.
Excerpt taken from the article in the December 2013 edition of L’UTILITERRE
Entrepreneur René Couture has developed a system that preheats the air entering the grain dryer using a high performance wood boiler.

At the height of the drying season the producer burned three quarters of a four foot cord of wood per day. The Paré family burns less wood during the winter despite heating two large garages and the family home. Come summer they may even heat the pool.
Since this is a first for Sequoia the installation in Compton has not yet reached its optimal performance. It is therefore arguable that the savings in money will increase over the next few years. This of course will depend on the price of propane, which at the moment hovers around 50 ¢/L. Note that the above stated figures have not been validated by an independent firm.
The Sequoia boiler can accept logs measuring up to 55 inches in length, once loaded it produces 3 000 000 BTU.
