Well, I decided to try and run the furnace humidifier without the furnace running. At first I just energized the solenoid that allows water flow through the furnace humidifer with a jumper and turning the blower on manual but then realized I can just increase the setpoint on the thermostat (no propane is hooked up to the furnace) and keep the blower on manually and the solenoid remains energized. The house humidity has increased axactly 1% every hour. I;m not sure if it is worth running the house blower for this. Does it sound worthwile? Would I get better results from a store bought house humidifier?
