Enduring Winter is just part of living in North East Wisconsin. From time to time, the winter temperatures we experience drop to sub-zero levels. While sub-zero temperatures might be a common occurrence for winter in Wisconsin, many people may not realize that there are certain levels of extreme temperatures and wind chills that our homes’ heating systems are NOT designed for: -20 to -30 degree temperatures with wind chills into -40 and approaching -50+.

Both newer and older homes will struggle to maintain temperature and the temperature could drop even while the heating system is working at full capacity.

What can you do to prepare?

  1. Raise the temperature in your home today, 2 to 4 degrees above your normal setting.
  2. Take all programmable thermostats out of setback mode and set on a permanent HOLD.
  3. If you have a furnace; replace the filter.
  4. Keep garage doors closed and limit opening exterior doors.
  5. Make sure air vents and radiators are not blocked or obstructed.
  6. If you have a 90%+ furnace and boiler, you must keep the intake and exhaust pipes clear of ice and snow. During these cold temperatures, ice can build up. A 90%+ furnace and boiler have 2 white PVC pipes; an exhaust pipe and an intake pipe that are generally on the side or back of your home.
  7. Share this information with family and friends.

If the temperature in your home is dropping and your radiators are HOT with boiler systems or you have HOT air coming out of your vents with furnaces, DO NOT PANIC. Please make sure that your heating system continues to operate.

If the temperatures drop in your home, it will not be able to recover until the extreme temperatures rise and the windchill diminishes. Our homes’ heating systems cannot overcome outdoor temperatures of -20 to -30 with wind chill approaching -50+. Your heating system in most cases is designed to maintain your indoor temperature set point (not increase) when the outdoor temperature is as low as -10 to -15 degrees.

To help minimize temperature loss you can boil water, make soup or stews; they help introduce humidity and warmer temperatures into your home. NOTE: DO NOT USE YOUR OVEN OR A GRILL TO HEAT YOUR HOME as these actions can produce harmful and potentially fatal levels of carbon monoxide! Please check on neighbors and elderly residents during these extreme temperatures. Stay warm and safe this week and share this post with any of your family and friends.
