installing a furnace type whole house humidifier
I'm feeling like I need a humdifier. The house has forced hot air, though I primarily heat with a wood stove. I've started looking around online and I see that there are two type of humidifiers out there: steam and evaporative. It looks like either type is available as an add-on to an existing furnace. I'm thinking that the evaporative humidifier looks like a it would do the job, and I'm inclined to get one as the price is much lower. I can see pricing, features, but I don't understand the motivation to get the more expensive steam humidifier. I would guess that a steam humdifier would be more expensive to operate too.
So, given that I'm looking to get the evaporative humdifier, is it reasonable for a homeowner to install it? Looking a the installation instructions I'm thinking it looks pretty straightforward.
I'm wondering if a compatible relay should be installed or if I would a "sail switch"? My furnace (model: NUGG100EA02) does not have fan relay to operate blower only. In my looking around, I've found that the Honeywell HE360A, can be purchased with an installation kit that includes a sail switch.
Any comments will be appreciated,
Thanks in advance
