« With our Sequoia boilers, the temperature is always constant. We’re comfortable in the greenhouses, even at night. Sequoia is a central heating system, which really cuts down on our need to handle the wood. We save a lot of time by loading only two big boilers instead of fourteen small wood furnaces. »
Ferme Sylvain Tremblay, located in St-Fulgence, in the Saguenay region, is a nursery that specializes in growing vegetables and annuals.
“January 2022 was an exceptional month with temperatures down around -35°C and about twenty consecutive days that were much colder than usual. We’d rather not think about how high our oil bill would have been!” says owner Sylvain Tremblay. “We have fourteen working greenhouses. Production starts gradually in January. Before we installed the Sequoia boilers, each greenhouse had its own oil and wood heating system. We were spending about $20,000 a year in oil and using 27,000 litres. On top of that, we were going through about a hundred cords of 16-inch logs. Heating a greenhouse is like heating the outdoors. To cut down on oil costs, we needed to feed our old wood furnaces every three hours, around the clock, which meant getting up in the middle of the night.”
Sequoia’s Blue Sky energy generator is a hot-water heating unit that runs on biomass fuel. The heat produced is distributed by the powerful Dragon Vert fan coils.
“We’ve been trying out the different Dragon Vert models to see how they perform, and we’re very pleased with all of them. They’re easy to hook up and use. Very powerful!” confirms Mr. Tremblay.
Attaching a hot-water coil to his existing oil furnaces gave Mr. Tremblay another economical heating option.
“We kept our oil furnaces as a backup heating system. So we use their blowers to draw heat from the radiators,” explains Mr. Tremblay.
At this farm in St-Fulgence, the Sequoia heating system is considered a major asset when it comes to greenhouse growing.
“With our Sequoia boilers, the temperature is always constant. We’re comfortable in the greenhouses, even at night. Sequoia is a central heating system, which really cuts down on our need to handle the wood. We save a lot of time by loading only two big boilers instead of fourteen small wood furnaces. We’ve also stopped using oil completely. Based on this year’s exceptionally cold weather, we estimate that we’ll need 90 4-foot cords per year. At $120 for a 4-foot cord, we think this is a good savings. Our Sequoia system heats really well,” concludes Sylvain Tremblay.
