“Sustainability is a large part of our overall business strategy. Our goal was to be fossil fuel free by 2015 and once we learned about the MESys AutoPellet wood pellet boiler, all the pieces began falling into place. We removed our oil system, including a 5,000 gallon buried oil tank, and the MESys system was installed right into our existing heating zones. We are now saving on our heating costs and the AutoPellet is maintenance free and as automated as our old oil system.”
— Tim Downing, Duratherm Window Corporation

“We had been researching wood pellet boilers when we discovered the MESys AutoPellet. The AutoPellet exceeded all others in performance and reliability and has a long track record in the heating industry. We had grown tired of paying for oil and are now saving on our heating costs. The easy emptying of the ash container, 2 – 3 times per year, is all the effort required by us. The folks at MESys have become like an extended family.”

Automatic Vacuum Fuel Feed
From the pellet mill to the burner, you never see or touch the fuel.
Automatic Heat Exchanger Cleaning
Heat exchanger tubes are automatically cleaned daily, only requiring annual cleaning. There is no need to shut or cool down the MESys AutoPellet for routine cleaning.
Bottom Fed Burner
Our bottom fed burner design eliminates emptying ash from the burn chamber for a restart, this results in no by-product build up. After a period of low-demand, only the application of air is necessary to restart.
