4. Adjust the Thermostat at Night

The US Department of Energy has stated multiple times that you can save 10% per year on your heating bills by turning down the thermostat by 10-15 degrees.

It makes sense to turn this down when you're sleeping, seeing as you're not really doing anything. Just grab a few more heavy blankets, and you won't even notice a difference.

 3. Add Moisture in the Air Using a Humidifier

During the winter due to not any fresh air coming in, the air can become very dry. 

Moist air feels warmer and also hold heat better, so investing in a humidifier can help you adjust to turning down the thermostat.

A cheaper alternative to this is simply adding house plants to your home, seeing as they are natural humidifiers.

2. Use the Sun to Your Advantage

One of the best ways to heat up the house free is by using that giant inferno in the sky.

Open the curtains on your south-facing windows during the day time to welcome that 100% free heat into your home.

Be sure to close them at night, as heat can escape thru that thin veil throughout the night.
