Growers can often reduce energy cost by 30 to 50% by using energy efficient growing practices, tightening the greenhouse enclosure to reduce infiltration losses, replacing inefficient heating systems and installing curtain systems. Often growers turn to wood as a way to reduce energy costs instead of implementing efficiency measures. But some of the wood boilers are very inefficient and may cost more to operate than if energy efficiency measures were implemented. The webinars will cover energy measures for greenhouse, thermal curtain systems and the use of biomass energy for heating greenhouses.
This presentation will look at different potential fuel sources (biomass & used oils), types of furnaces and boilers including outdoor wood-fired hydronic heaters, pellet or grain fired boilers/furnaces, stand alone stoves and a case study of two greenhouses. We'll wrap up the presentation with information on energy grants to help pay cost share the capital costs of energy saving equipment or heating equipment to burn a renewable fuel.
