MYTH #3: Turning 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. www.consumerenergycenter.org”
