Humidity

We have a customer with a hydroair system that would like to add a humidifier to the system. I was thinking that a standard pad style wouldn't be very effective considering the lower temp air. Would a steam style work better? If so what is a good brand to look at?

Hydro Air

I am assuming this is a heat pump. If so, I had good success with a pad type by feeding it from my hot water line rather than the cold. All the humidity I wanted in my home with an air to air heat pump.

Hydroair

Actually this is a hotwater hydroair with a boiler as its source. Actually this was an "indirect" steam heating system which was converted-to forced hydro- due to the excessive amounts of fuel used to heat the incoming outside air. The house has all french doors on the first floor and leaks alot of air, the homeowner is aware that this is causing the dry indoor conditions. At this ponit he would simply like to add a high capacity humidifier and work on the leakage as he restores the house.

if he want to be able to maintain the humidity setting and
have enough capacity on those very cold days,then a steam
humidifider with a control that will bring on the fan even when the heat not calling is the way to go.

go to

humidity.com. look at the nortec resdelux. it will handle a 30,000 cubic foot house.

Steam is the way to go

Steam is the way to go. Skuttle and Honeywell both make fine units both available in 220 volts which is what you have at the air handler. I would control it with a humidistat. Its a fairly simple wire job as well. 24V transformer, multi purpose relay and you are good to go. The relay allows you to run heat as a priority by opening the contact to the fan motor being used for humidification. Low speed on the fan works best for humidification.

Just my 2 cents
