    I'll be honest and say that I'm a home owner looking for some advice on how to humidify a 2 story house with hot water baseboard heat. I've talked to a few HVAC guys and they said to use the individual room humidifiers. I want to do the whole house. Does anyone have any experience with the AprilAire 360?? Thanks.

    Having not installed this unit before, as a whole house claim with no ducting leads me to beleive that some areas may not benefit from the humidifier. Advertised for over 4k sq ft for homes with radiant heat I would have to see the install specs to really know for sure the coverage area. You may have to install a ducting system.

    Humidity distribution is one of my concerns with that AprilAire 360 unit. One of the HVAC guys I talked to stated that humidity will travel throughout the house no matter where the unit is placed. If it is mounted in the basement, up thru the 1st floor, will the humidity reach the 2nd floor?? Will it over humidify the first floor??

    Humidity will travel to the driest point.

    You can use this with a separate supply and return, like in a closet, behind a wall, or under a floor

    Every Skuttle steam powered humidifier I have experience with has been trouble. Problems so far are elements that burn out in a few years, rotted duct work, and plugging. Now no doubt, if the units had flushing timers on them, maybe these issues would not occur. Steam humidifiers are expensive to buy and very expensive to operate. Years of experience lends me to agree with the HVAC contractors that say to install a freestanding unit in the living area. That way you get to see the unit and maintain it.

    The ones I buy have a flushing timer, but I still need to do a service call once a season to clean it. And I charge for that. The steam units are the only ones that will keep the humidity at a level, all the bypass units ride the furncae run. Just depends on whether or not your customer wants to pay a little extra to have the comfort level.

    Are you getting nose bleeds? I'm wondering why you need the Humidifier if you have hotwater heat??? Hotwater heat auto. puts humidity in the air. Maybe whomever installed the baseboard under sized it. Post a sq ft of a room and location in US and I will be able to tell you approx how much base you need...

    Confused

    We're not getting nosebleeds, but we have a lot of static electricity and the dog is scratching up a storm!! How can hot water baseboard heat produce humidity?? It's not steam heat.

    Steam is produced from hotwater as I'm sure you know. That water in the boiler is anywhere from 180 to 190 degrees when running. Water boils at 212. You still get steam before the boil, just not as much. Easiest way to say it without getting all technical on you, lol.

    Your static problem still leads me to believe you are undersized in baseboard. I live in upper PA where it gets extremely cold and dry, in fact you get shocked when getting out of your vehicle in the winter if you don't ground yourself first, lol. I have installed many hotwater heat systems ranging from 1200 sq ft homes to 3200 sq ft homes. Most have carpeting and all and atleast half have animals. I haven't had one complain of no humidity, but I have had some say they need a de-humidifier. With furnaces you get dry air hitting the cold air causeing low moisture which causes static electricity, dry nasal passages, respiratory problems, etc. Here is a link to answer your questions about the Aprilaire 360.

    Very good reading there. Hope things work out for you.

    I live is SE PA!! Where in PA are you?? Maybe I'm missing something in your explanation. My heater and heating system is a closed system. I don't see any steam coming from my heater, so how do you explain the humidity?? My house is about 2500 sq. ft. and the majority of the perimeter, on each floor, is lined with hot water baseboard heat(not cast iron).

    I've looked into that AprilAire unit, but I really don't have a place to easily install it, except in the basement and cut thru the first floor with ductwork.
