Last week, we wrote about how a whole-house humidifier can benefit you this coming winter. Humidity levels often drop during the cooler weather in Southern California, and heating systems like furnaces have a tendency to dry out a home’s air. The right professionally-installed humidifier will do wonders at keeping a home more comfortable and the heating system more energy efficient.
To satisfy the curious, we’re going to go over the basics of how a whole-house humidifier operates. If you have any further questions, or if you wish to arrange to have a humidifier installed in your home, just call our team.
The Basics of a Whole-House Humidifier
A whole-house humidifier is an appliance that is integrated into your HVAC system, making it very unlike portable humidifiers that simply put steam into the air from the middle of a room. The humidifier works in connection with the heater (or AC) and creates water vapor that enters the ductwork. The water comes through a supply line that connects to a fresh water pipe nearby. A water feed tube then distributes the water into an evaporator pad, which holds the water during the period when it evaporates into vapor. The pad spreads out the water evenly, which makes it easier to evaporate (and also collects any minerals that might be in the water supply). This pad should be replaced once a year, usually before heating season. Any water that doesn’t evaporate into the air flowing through the humidifier is drained into a pan and then sent through a pipe under the humidifier into the drainage system. This will help prevent the growth of algae and bacteria inside the humidifier.
A device called a humidistat is responsible for controlling the humidifier. You should set it around 30% to 45% relative humidity when your home’s air is too dry. The humidistat will keep the unit working until reaching the desired humidity level, much the same way a thermostat works for a heater or AC.
