Enertec challenges the status quo and strives in all our work to reduce energy use and cost for our customers. We believe the information below will be a great resource for you.


It has been demonstrated that heat treatment is effective against a wide variety of pathogens, with no phytotoxic effects under proper system upkeep (Van Os, 2010). Unfortunately, operation costs are often high and directly dependent on the cost of natural gas, which may fluctuate significantly from year to year (National Energy Board, 2012). Potentially high costs may mean heat treatment is best employed for disinfecting the smaller amounts of water used in highly disease susceptible areas, such as those dedicated to plant propagation (Hong, 2005).
