Humidifier and vapor question
In my three bedroom trailer, I've got a floor model
humidifier. I have to feed it at least two gal of water d ay, to keep the indoor air comfortable. Maybe even more than that. From my old fire science days, I remember that water vaporizes, and increases 1800 times volume. That means I'm putting 3600 gal a day of vapor into my trailer. Some condenses on the inside of windows, but not two gal per day worth. I wonder where the rest of that vapor goes? I don't have any windows cranked open, and I'm not holding the door open all day. Makes me wonder what I can do, to reduce the air and heat loss? -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

Cold, dry outside air makes it's way inside, replacing warm moist air. Where does combustion air for furnace, WH, etc come from? New furnaces typically use a vent pipe going outside, while old furnaces use the building air around the furnace. If it's condensing on the windows, the humidity is too high. The indoor humidity should be adjusted down as the outside temps drop. My furnace humidifier has an outside temp sensor to do that automatically. |

Kitchen hood vent, two bathroom vents, cloths dryer vent. All the sinks have vents that suck air from behind the wall when the water is drained. Then there are all the openings when plumbing is through the floor. I am sure there are others. Just look and think. Paul |

I do have a clothes dryer hole in the floor, wonder if it's still there. The vent over the range, has cardboard stapled over it. Though, it could use some sheet plastic in addition, I'm sure. Plumbing poke throughs, I'd not even thought of that. There is still a "stack" flue pipe for the old furnace, I've got that blocked since I put in a 90 percenter. And the 90 percenter draws combustion air from under the trailer. Plenty to think on. -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

The cold extremely dry air that blows in through the cracks pushes the warm moist air out the other side. You gotta get a couple of those "quebec garages" I mentioned the other day to seal the trailer into. |

What you want is a smoke generator - then stand out side and watch where the smoke comes out. Coloured smoke would be more visible - red or yellow. |

Get one of those infrared thermometers.
I'll bet you'll see a lot of leakage without adding gases to your environment. |

That may be the least of your problems. I'm most comfortable with a dewpoint around 45F inside. If it's colder than 45F outside, that means that somewhere inside your walls, it's 45F. And a bunch of that 2 gallons a day is condensing there. I'd worry a lot about mold. Perhaps run an exhaust fan so that the leakage is coming in. Water won't condense out of air that's warming up. That's a spooky thought. Might keep me up at nights. What is that stuff hanging off the walls, coming to get me? -- .. Christopher A. Young Learn about Jesus www.lds.org .. |

The fact that you are adding moisture constantly proves you have a huge amount of infiltration (outside air coming in through gaps). You'd be better off finding and sealing them, then you can add much less water, maybe none. When we lived in Germany, our house was so tight that with just normal water from breathing, cooking, and the occasional shower, the house would fill with mold if we didn't open windows twice a day. There is plenty of internal humidity generation if you don't lose it all to a leaky house. I tried walking around with IR thermometer, and check various points. I probably don't have the technique right. What I found was that the outside skin of the trailer was all the same temp, and I couldn't find much variation indoors.

You measure the amount of water in the air as relative humidity, not gallons. If you know the total air volume of you trailer and it's relative humidty before you added the two gallons you could compute the new relative humidty. But it would be easier to just measure it. |

Humidifier and vapor question
From my old fire science days, I remember that water vaporizes, and increases 1800 times volume. That means I'm putting 3600 gal a day of vapor into my trailer. No, that's not what it means. Gas volume is very temperature dependent. This is a complete red herring. Gas volume isn's additive. If you add 10 gal. of N2,STP and 10 gal. of o2 you don't get 20 gal. of gas, STP. Some condenses on the inside of windows, but not two gal per day worth. I wonder where the rest of that vapor goes? I don't have any windows cranked open, and I'm not holding the door open all day. All olf the vapor dissolves into the room air.From there it travels throughout your trailer finding places to hide. Your furniture probably absorbs a lot of the water. The air in your home does replenish from outdoors, so water goes there, as well. Makes me wonder what I can do, to reduce the air and heat loss? If you make your house gas tight you will eventually asphysiate due to lack of Oxygen. Dave M. |

The furniture will come to an equilibrium with the air. Since the air is continually dry despite his humidification efforts, water will likely move from the furniture into the air. The water he puts into the air is being driven outside almost immediately. There are too many air changes happening. Find and plug the leaks. |

Your carpets, rugs, bedding, clothing in closets, etc., are getting slightly damper from the humidifier. I notice it takes a long time for my humidifier to humidify my home. That's because it first has to "humidify" my wall-to-wall carpets, which soak up humidity like a sponge. (That's why a great way to humidify a home is to just shampoo the carpet.) -- Steven L. |

IR cameras have been around AT LEAST as long as the "home inspector" "profession" When you charge to do a job, you do the job to the standard of the time - making use of the technology available to do the job right. A home ispector can get a thermal imaging camera for less than $600 - or a better one for the $1000 range. Not having one puts you in the bottom of the stack of a somewhat shady business - to the most part unregulated and untrained charlatons. If I'm hiring a home inspector, he WILL have the equipment to do the job. And he WILL have building construction experience and/or construction technology education. |

From my old fire science days, I remember that water vaporizes, and increases 1800 times volume. That means I'm putting 3600 gal a day of vapor into my trailer. Some condenses on the inside of windows, but not two gal per day worth. I wonder where the rest of that vapor goes? I don't have any windows cranked open, and I'm not holding the door open all day. Makes me wonder what I can do, to reduce the air and heat loss? I noticed the air is pretty cool over mine. It is a swamp cooler ! I wonder how much negative btu it taking away ? I just measured temp differential. It's not that much. 6-7 degrees, but it's moving a lot of air. Greg |

You know exactly how many BTU's it takes to vaporize that much water. Google heat of vaporization. 970.4 BTU/lb ~ 8000 BTU/gallon. I just measured temp differential. It's not that much. 6-7 degrees, but it's moving a lot of air. Greg |

When you charge to do a job, you do the job to the standard of the time - making use of the technology available to do the job right. A home ispector can get a thermal imaging camera for less than $600 - or a better one for the $1000 range. The one we use at work cost $3500. At times of the year when the inside and outside temperature vary greatly, like the dead of winter or dog day summer, they are very useful. But you have to inspect all year round. If you need to know infiltration, you have to do a blower test anyway. |
