Myth: Closing rooms saves energy
When people used to use wood stoves or fireplaces as their main source of heat, they would close off other parts of the house, so the heat would stay centralized. That doesn't work with today's heating systems. Restricting airflow through these systems causes your unit run longer and harder to maintain a constant temperature.
Myth: Maintaining a constant temperature saves more energy than raising and lowering it
Why would you want to heat your house while you're at work, or while you're cozy, cuddled up in your down comforter? Keeping your thermostat at a constant temperature wasteful. If you're at home during the day, set your thermostat to 68 degrees. At night, turn it down to 55 degrees. You'll reduce your energy cost by 5% for every degree you lower your thermostat between 60 and 70 degrees.
Myth: Turning the thermostat on high heats rooms faster
This one is common sense. If you crank your thermostat up to 90 degrees hoping it'll heat your home faster than setting it at the constant temperature you'd like to reach, you'll be disappointed. Your heat pump can only work so hard and so fast.
Myth: Ceiling fans don't help during the winter
We all know heat rises, but what if you could pull it back down to where you’re curled up on the couch, wrapped up in your Snuggie? Most ceiling fans have the ability to do that. Reverse the switch on your fan so the blades blow upward. It forces the heat back down to thaw you out on a cold winter day.
Myth: Fireplaces are efficient
Do you have a traditional fireplace? Many are big energy losers. They suck the heated air from the house and pull it up the chimney. So if you’re not using it, close the damper. Wait until the embers are out first.
Myth: Closing the blinds keeps the heat inside
On sunny days, let the rays shine in and heat your home for free; however, having the blinds closed at night does help insulate your home.
Myth: Using electric space heaters saves money
Given that electricity is typically between four and ten times the cost of natural gas, running just two electric space heaters can cost the equivalent of heating an entire home with a gas-powered system.
Myth: New windows equals significant cost savings
Replacing single pane windows for energy star rated, dual pane windows will save energy. That energy savings, however, is a function of the size and number of windows in your home, their orientation and overhangs, and the location of your house and the climate zone in which you live. This typically amounts to a small fraction of your total energy use, and given the expense of replacing windows, there are typically more cost effective ways to reduce your energy bills.
