Turn down thermostat savings

Every night my automatic thermostat reduces my home temperature from 68 to 55 degrees. I like cooler sleeping and wondered if I could turn it down even lower. But is there a point where the savings earned by reducing the temp will be offset by the time it takes to warm the home in the morning? Can I go too low?  I have a forced air furnace with natural gas fuel. The furnace is 3 years old but is not a super efficient model. It still has a metal flue to the outside.

Re: Turn down thermostat savings


Turn your thermostat down 3 degrees.

Leaving your thermostat at the same setting. Do you set your thermostat at a specific temperature and never touch it? You could be wasting as much as $180/year, according to ENERGY STAR. 

Instead, you should change your thermostat temperature setting whenever you leave your home for 8 hours or longer. After all, there’s no need to heat or cool your empty home to the same temperature as when you’re home.

When your home will be empty for 8 hours or longer, set your thermostat 5°-8° higher in the summer and 10°-15° lower in the winter.
When you get home, set the thermostat back to your comfortable setting.
Doing so can save you 5-15% on your yearly energy costs, according to the U.S. Department of Energy. 

Of course, remembering to change your thermostat every time you leave your home can be difficult. That’s where a programmable thermostat comes in. Programmable thermostats can be set to your schedule so that it automatically makes these adjustments for you.
