Optimize space heating

These devices offer better control over heating periods and temperature settings. Save energy by programming them differently for weekends and weekdays, depending on building occupancy. A drop of 1°C (1.8 °F) over a 24-hour period can reduce your heating costs by up to 5%. A decrease of 3°C (5.4 °F) over an 8-hour period can reduce your heating costs by up to 6%. See the grant available for the purchase of a programmable electronic thermostat.
