Take control of your home heating using a smart thermostat. Create room-by-room schedules to heat just the room you need, in most cases right from the comfort of your favourite chair using your smartphone. Believe it or not but 82% of energy consumed in the home is used by heating and hot water. With a smart thermostat, you could reduce this by as much as 40% simply by more efficiently managing your heating schedule. Better yet, in most cases, they can directly replace your existing thermostat.
