During the heating season, what is the ideal temperature to set my thermostat at during the night and when I am away?
It is recommended that settings of 20°C during the day and 17°C at night (or when nobody is at home) provide optimal comfort and efficiency. As a rule of thumb, for every degree you consistently turn down your thermostat over an eight hour period, you will save 2 per cent (per degree) on the space-heating portion of your energy bill. A programmable thermostat will help you to regulate your daily and weekly settings and optimize your energy savings. 3) Is it true that if I turn down my thermostat, more energy is used to bring the temperature back up to the same level? No, this is not the case. In fact, if you turn down your thermostat for more than a few hours you will save energy. Here’s why: The energy “saved” during the time the temperature is dropping (ie. from 21ºC to 18ºC) offsets the “extra” energy used to bring the temperature back up (to 21ºC). Over the period where the temperature is continuously at the lowest setting (18ºC), this is considered saved energy on your heating bil
