Despite their popularity, central forced air heating systems have a number of systemic problems. They do the job decently enough, sure, but they are a “one size fits all” solution with all the negatives that go with it. Some homeowners opt for entirely new systems to get around these issues. For those that don’t want to invest that much money, however, an effective solution can be found in zone control. Let’s take a closer look at the issues with central forced air heating, and the ways that zone control systems can mitigate them.
Central Heating Problems
The core problem with central heating is that it is simply inefficient most of the time. The whole system is controlled by a single thermostat, usually installed in a hallway close to the center of the house. This is done to prevent the thermostat from being affected by temperature fluctuations in the outer areas. The thermostat cannot sense the temperature levels throughout the house, of course. It can only register temperatures in its general vicinity.
When the thermostat finally does turn the heat on, the heat is directed to all rooms throughout the house. There is no way to direct the heat to the one or two rooms that are actually occupied. Instead, the entire house receives heat until the thermostat is satisfied. Not only does this waste energy (and thus, money) but it can create wide temperature fluctuations in rooms further away from the thermostat.
Zone control attempts to rectify this inefficiency through the installation of buffers in the ducts leading to each room. These buffers can either open or close, controlling air flow to that room and directing it to other areas. Each of these buffers can be linked to its own thermostat, allowing individual rooms to be set to individual temperatures.
This solves the inefficiency problem that central systems struggle with. Multiple thermostats assure that each room is kept comfortable, while directing air flow to where it is actually needed. This prevents the massive waste of energy that most central forced air heating systems perpetuate.
