Thermostats control the operation of heating and/or cooling systems in your home. Proper location, maintenance and operation of your thermostat keeps indoor temperatures comfortable and can save on utility costs.
Your thermostat should be located on an interior wall near the center of your home. It should not be in direct sunlight or near radiated heat from fireplaces, radiators or other heat sources. Generally, the thermostat is placed outside the kitchen. It should also be away from doors and windows that open and close frequently. Thermostats are generally located about five feet above the floor so they can be read or adjusted easily, and they may be controlled by a gauge, a dial or digitally with a panel of buttons. Thermostats should be assessed as part of a home’s general mechanical system during a home inspection.
Most thermostats for gas-fired appliances also have a variable anticipator to help prevent overheating. The anticipator “fools” the heating unit into shutting down just before the room hits the set temperature so the heat remaining in the furnace finishes the job.
Whenever changing a thermostat or performing routine maintenance, it’s a good idea to make sure the settings for the anticipator are correct.
Consult with your local NPI or GPI inspector for an assessment of your home and appliances.
