A buddy who works at Enmax said that if you use your programable thermostat but only vary from 2 degrees then it's the best. Constant works best if you have an older house without a programable thermostat as it probably isn't as well insulted as a new home.
Any change more than 2 degrees (say 17C during the day and 22C when you're home) you'll end up spending more money as the furnace has to work hard to increase 5C. The idea is to not make your furnace work that hard.
