Heating Contractor Guide: Where to Place a Thermostat for Accurate Heating

It’s easy to forget that with your furnace in the basement churning away all day to keep your Lakeville home warm, but your thermostat is the single most important device in ensuring your home is heated to the temperature you want. If it stops working or it misreads the temperature inside your home, your furnace won’t know what temperature it actually is and will turn on and off at the wrong time.

Where Not to Place Your Thermostat

To avoid inaccurate readings, avoid placing your thermostat in the following locations:

Direct Sunlight – Direct sunlight will almost always increase the perceived temperature of the thermostat. Unless you live in a greenhouse, this will be very uncomfortable for everyone in your home.
Windows – Windows can result in direct sunlight and breezes. If the windows are not properly sealed, cold air can blow in and make it seem cooler in your home than it really is. In any of these cases, your thermostat will misread the indoor temperature.
Drafts – Drafts from improperly sealed doors, windows, or anything else in your home can negatively impact the thermostat.
Heat Vents – Don’t place your thermostat near a radiator or heat vent where it is likely to be warmer than anywhere else in the house.
Kitchens – Kitchens tend to be warmer than other rooms in the house, especially when in use. Avoid placing a thermostat here unless you have a zone control system and your kitchen is separate from other rooms.

A properly placed thermostat will ensure your home is heated or cooled to the temperature you desire regardless of outdoor conditions. If you’re unsure whether your thermostat is calibrated properly, check the temperature with a separate thermometer in a different location in the same room. If it is significantly warmer or cooler in one place than another, try to determine which is more indicative of the actual comfort level in your home. When properly located, your thermostat should never be an issue again.
