Uneven heating has been the bane of homeowners since the advent of heating systems. Hot and cold spots are uncomfortable, often difficult to get rid of, and seem to show up out of nowhere for no reason at all. Though hot and cold spots may seem infuriatingly intractable, there are a few things you can do to address them. First, it helps to understand where they come from.
Hot and cold spots have a few different causes that often factor into their creation. The first of these is simple forced air system operation. As it turns out, forced air systems are not normally all that efficient at regulating temperature evenly. In the case of heating, the heater will be hampered by warm air’s natural tendency to rise.
When a forced air system pumps heat into a room, the warm air will rise to the ceiling. This prevents the room from heating up quickly, at least in the areas that people are actually going to occupy. As the air cools, it sinks to the floor of the room. The result is a striation of both hot and cold spots in the same room, making it very uncomfortable for the room’s occupants.
Another common cause of hot and cold spots is the combination of thermostat placement and poor insulation. No home can be perfectly insulated, of course. As soon as your system turns off, the home will begin to equalize with the outside world from the outside in. If you have poor insulation, this will happen much faster. That, combined with thermostat placement, can result in wide temperature swings.
Essentially, the thermostat turns your heating system off once it senses the correct temperature. The problem is that the thermostat can only monitor the temperature in the room it is installed in. This is often in an interior area of the house, to keep the climate as consistent as possible. So, the outer rooms will cool off much faster and remain cold until the room with the thermostat begins to cool off.
