Thermostats and Galileo Thermometers: How They Interact


If youandrsquo;re looking for a way to bring form and function to your home through decorating, consider Galileo thermometers. Invented in the 1600s by Galileo himself, they combine beauty with functionality. They use colorful floating balls in a liquid to indicate the temperature.

How They Can Be Useful

Aside from the colorful accent they can be in your home, these thermometers will give you an idea of how different the room temperature is from the area near the thermostat. Inconsistent temperatures arenandrsquo;t uncommon with forced-air HVAC systems, although builders and HVAC contractors make every effort to prevent them.

Using Galileo thermometers to measure the temperatures in these distant or atypical rooms will help verify which rooms need your attention to improve comfort. The thermometers might reveal places where you have ductwork leaks You and your HVAC contractor can take steps to balance the temperatures to make all the spaces in your home comfortable by:

  • Air balancing your ductwork. It might be possible to change the size of the ductwork going into one of the rooms that is less comfortable. You can also use register covers with adjustable louvers for rooms that receive too much conditioned air.
  • The thermostat is in the wrong place. It might be exposed to direct sunshine or receives strong drafts from the outdoors.
  • Zoning your home. A zoning system gives you control over the temperatures in each space of your home. The technicians from Valley install mechanical dampers in the ductwork that open and close, depending on that areaandrsquo;s need for conditioned air. Each zone has its own thermostat that tells the HVAC system when to run and where it needs to send the conditioned air.
