Galileo Thermometers and What They Say About Your Thermostat

Galileo Thermometers and What They Say About Your ThermostatBesides being attractive and decorative pieces for your home, Galileo thermometers can help you discover how accurate your HVAC system’s thermostat reads. It may also tell you how well your heating system delivers conditioned air to each room in your home.

How They Work

A Galileo thermometer contains colorful glass bubbles that float in a liquid. As the temperature of the liquid rises, the balls rise, too. Each bubble has a weighted tag at the bottom to indicate different temperatures. They tend to be accurate, which makes them not only decorative, but useful. Before you use this thermometer to evaluate the accuracy of your thermostat, compare the Galileo to another thermometer you know to be dependable.

How to Compare

Find a way to set the thermometer as close the thermostat as possible and wait until the liquid in the thermometer has adjusted to the ambient temperature. Compare the reading on the highest or lowest bubble to the temperature the thermostat indicates. They should be fairly close. If you know that the Galileo is accurate, and the thermostat reads differently, it could need calibrating by a NisAir HVAC pro.

After you’ve tested the immediate area around the thermostat, move the Galileo thermometers around the house to see how well the conditioned air circulates. You may have to make thermal allowances for differences in the rooms like air leaks and inefficient windows. A room that isn’t energy efficient won’t maintain its comfortable temperatures as long.

Solutions

If your home is energy efficient and there are significantly different temperatures between the rooms and the thermostat, you may need to consult your HVAC professional for a solution.

You might be able to install a zoning system to control temperatures or have the ductwork balanced in order to alter the airflow to accommodate temperature differences. It may also be something as simple as a thermostat located in the wrong place.
