Heating air does not remove moisture, but it does dramatically lower the relative humidity — which is why a properly heated house in January can feel like a desert.

The symptoms are familiar: static shocks off every doorknob, dry sinuses and sore throats, cracking in furniture, flooring and instruments, and skin that never quite settles. There is a comfort argument too — air at a sensible humidity feels warmer than dry air at the same temperature, so people often find they can set the thermostat a degree or two lower.

A whole-house humidifier is plumbed into the ductwork and controlled by a humidistat, so it manages the whole house automatically rather than one room at a time out of a tank you keep refilling.
