Is it cheaper to leave your heating on all the time or turn it on and off? | TheGreenAge

As the article discusses…the answer is it depends and the best approach is to conduct a test to see how your building performs.  Most energy efficient homes have a programmable thermostat so the heating isnt either on/off but operates based on outdoor temperature setpoint, indoor temperature setpoint as well as setup for night setback.

One other thing to consider is whether your heating system is oversized. If one decides to leave their system on 24/7 the oversized unit may short cycle (turn on/off in short period of time before reaching steady state) to maintain a setpoint which wastes energy.
