New high-efficiency furnace installed

nvman | Posted in Mechanicals on

I had a high-efficiency forced-air furnace installed along with a setback thermostat.
The installer said that with these new furnaces, you just set the thermostat to one temperature.

Is that true?
I live in North Vancouver, BC where the climate is milder but I would think it is still more efficient to setback the thermostat at night.

    Thermostat setbacks save money, except for some types of air-source heat pumps or hydronic systems with in-floor tubing.

    The better your home's envelope, however, and the higher the efficiency of your heating and cooling equipment, the less money you will save by thermostat setbacks, and the less necessary setbacks become.
