Steam humidifier Brochure
A steam humidifier can accomplish up to 55%+ humidity in some homes because it has it's own water reservoir and heater. The humidifier is wired in line with the furnace and thermostat and when your humidistat on the wall calls for humidity to be added the humidifier heats the water to a steam and can then bring on the furnace blower independent of the heat.
Not only does this greatly improve your control over the humidity level in your home but it also reduces the amount of gas being used to heat your home. A home for example at 50% humidity and 68* will feel the same as a home at 25% humidity and 70*
