I am planning on having a humidifier installed into an existing system. I have a proposal from a good contractor with two different options. I would like to get some opinions on which option is better.
Background: This is for a 1750 square foot 3 level townhouse. Existing furnace is a Carrier Infinity 80 (58CVA) with Infinity controller/thermostat and Infinity 24ANA1 AC.
The two options are:
1. Honeywell 9 Gallon True Steam Humidifier HM509DG115
2. Aprilaire 800
The contractor is suggesting option #2 because of the hard water in this area. Option #2 would also require running wiring to the circuit board. Which means some additional dry wall repair.
Here are my questions:
1. Any opinion on the two different humidifiers? Is the Aprilaire worth the price difference?
2. Can both be controlled by the Infinity controller/thermostat? How well does this work? Can I just set the humidity level on the Infinity thermostat and then it will take care of everything? And when needed it will lower the humidity based on the outside air temp like the Aprilaire controller will in automatic mode?
3. Why would the Aprilaire require the additional wiring? I'm guessing this is to get 240V? Is that needed for my setup? It looks like the 800 can run with either 120V or 240V. It will just have a lower capacity with 120V. Is that correct?
