Question about Aprilaire 700 Humidifier
I live in a Townhome - 1600 sq.ft built 13 yrs ago. 3 yrs ago I purchased the Model 700 with the automatic control and external temperature sensor. I live near Washington D.C where average temperatures in Jan and Feb is around 30-35 F. Very rarely it drops to 10 F - once or twice a year. I have alway been suspicous of the efficiency of the humidifier. I recently got an authorized dealer to make the control manual and change the water panel. They found the solenoid faulty and replaced it under warranty. I now get 1 quart of water from the drain in 2 and half minutes and this appears to meet the specification. I was hopeful that by keeping the control at 45% I would get 40% at the least but I never see readings better than 33% - with my Brookstone monitor and also matching the "click" on the Aprilaire humidistat. I have checked with the authorized contractor and they now say that this is the best I can get. I somehow am not convinced and was hoping to hear from other Model 700 owners if they have this problem and how they deal with it. I plan to also work with the Aprilaire regional manager but would like some more facts when I meet with him.
If it is set up right, you should be able to run your fan 100% of the time and the humidifier will come on when there is a need for humidity. you can experiment with leaving the fan on and see if this helps. it will run your electric bill up a little and also you will have a lot of waste water. that is a drawback to the bypass type humidifiers. also a factor is if the water supply is hooked up to the hot or cold side. it will humidify better on the hot side, but you tend to get more deposits that plug the solenoid over time and you will be running your water heater quite a bit. 1600 sqft may be pushing the limit of this humidifier.
