How a Bad Thermostat Can Ruin Your Home Heating


No matter how new or sophisticated your heating system may be, a bad thermostat can cause significant issues within your heating system. Nevertheless, you cannot fix the problems if you are not aware of the signs of a faulty thermostat. With that in mind, here is an overview of the various ways a bad thermostat can ruin your home heating.

Computer Error

If you have a modern thermostat, this means it is most likely computerized. Although computerized systems can provide us with an array of benefits, they can also be problematic when they are not functioning correctly. Moreover, just because your thermostat may be experiencing a computer error doesn’t mean it will immediately cause problems. Instead, it may take a while before the problem becomes apparent. So, if your thermostat is suddenly having unexplained issues, it might be time for a replacement.


Another way a bad thermostat can ruin your home heating is if it is in the wrong location. For instance, your thermostat should not be installed where it will be exposed to direct sunlight. Moreover, the most ideal location for a thermostat is around 5 feet from the door. This is because the location of the thermostat can affect the accuracy of the reading. So, for instance, if it is placed in direct sunlight, the thermostat will automatically read a higher temperature than if it is not in direct sunlight.


Moreover, if you are not keeping your thermostat clean, this may also affect its functionality. This is because dirt and grime can build up on the inside of the thermostat over time. Once this occurs, it will have a negative effect on how well the thermostat works. Either way, while older thermostats can be cleaned by dusting beneath the cover, newer ones often require a qualified professional to avoid breaking or ruining the device.

Old Thermostats

Although newer thermostats are subject to human error, older thermostats often have way more problems than newer ones. So, suppose you are noticing that you are having trouble setting or reading your thermostat or other thermostat-related issues. In that case, it may be time to consider upgrading to a modern thermostat.

Improper Installation

Lastly, thermostats may become problematic when they’ve been improperly installed. Although the process may seem simple, properly installing a thermostat is more complicated than it seems. Therefore, many people make the mistake of going the DIY route, which often causes issues later. If your thermostat is malfunctioning and was not installed by professionals, it may be time to get it replaced or reinstalled.
