4 Home Energy Myths Debunked

  • Plumbing Preventative Maintenance

  • Like other fables, home energy myths tend to be accepted and passed along without ever being subjected to scientific proof. Relying on untested methods for energy savings often results in the opposite: increased energy use and higher operating costs. Science doesn’t yet know everything about how to make a home as energy efficient as possible. However, we can be certain about a number of things that don’t work. Here are four home energy myths that don’t stand up to a closer look:

    home energy mythsMyth: Upgrading attic insulation only causes more heat loss through the walls and floor.
    Fact: Heat energy inside a house isn’t like air pressure. Fixing heat loss in one spot doesn’t increase heat loss elsewhere. Heat passes through solid surfaces by conduction and radiation. Wherever it’s installed, proper insulation inhibits heat loss and doesn’t cause it to increase elsewhere.

    Myth: Closing supply vents in some rooms saves energy.
    Fact: Your furnace or air conditioner doesn’t “know” if vents are open or not. It just keeps on generating the same amount of heating or cooling and the same amount of energy is consumed whether or not all vents are open. Closing supply vents may actually cause the system to run longer “on” cycles and use more energy.

    Myth: When you turn off an electronic device, it stops consuming electricity.
    Fact: Many devices such as battery chargers, printers and home entertainment equipment actually go into “standby” mode when turned off and continue to use some electricity, although at a reduced amount. Plugging these devices into a switched outlet strip then turning off the strip is the only way to completely stop electrical consumption.

    Myth: Replacing standard windows with high-efficiency windows pays for itself in energy savings.
    Fact: Not for a very, very long time. The high cost of window replacement rarely pays for itself in a reasonable time frame. For a low investment and fast payback, caulking and weatherstripping to seal air leaks and upgrading attic insulation are a better bet.
