I am working on installing a 450cfm exhaust fan in my garage/workshop to help ventilate from welding/paint fumes and deal with humidity in the winter (gets high from snow melt off cars). I think it would work for my application but I can't find anything on google about it.
I have found that makeup air requirements aren't always addressed as changes are made in older structures. The building that I'm currently doing maintenance work on has several issues with makeup air and air circulation. Bad engineering in these can lead to inefficient and possibly hazardous operation such as darthmal related.
Is it illegal to not have a fresh air or make up vent in Thurston County, Washington? Because my furnace has a fresh air vent on it but it gets it from the garage, and sometimes gas fumes may make there way into our house. What should I do?
My problem is I have one fireplace. It recently start to spew smoke back into the house even though I have the flu fully open. I also started to smell firewood smoke in the basement near my furnace, which seems to vent out th the same chimney. There two small hinged doors at the bottom of the wall where the furnace vents out and I don't know what they are for. I was told for ashes but they are both empty. I called a chimney guy but without looking he wants to replace everything and wants my kid
@Benny902100 It depends! What's the difference between the humidity indoors vs. outdoors, and what are you trying to achieve? That's a rhetorical question. I'm not trying to generate a thread. Just understand your mixing outdoor air with indoor air. Remember back to your high school physics class to imagine what will happen. You can also read all about humidity and air temperatures at my AsktheBuilder website.
This is a good video that addresses concerns that many homeowners know/care little about. I work in HVAC, so I have to deal with air flow and air distribution problems in new homes. New building codes almost always deal with flue venting issues because they are a matter of life and death. Now that homes are built to be as air-tight as possible, makeup air is a bigger problem.
If given the product and an opportunity to test them, the answer is yes. Perhaps the more important question is one for you. :->>>> I went to your channel and you've been on YouTube for over three years. But you've never made one video, there is no information as to who you are, what you do, your qualifications, etc. It seems that you might know something about this topic, so why don't *you* make a series of videos about IAQ, systems, etc.????
No offense taken at all. When I see expert comments like yours, I always click to see the channel. I try to encourage those that seem to know stuff to make videos. We'd love to see a quick video of your system or the system if you install it later.
The always-open feature was designed by the inventor to provide the needed intake air when other things in the house eject air. Bath fans, kitchen fans, central vac units, fireplaces, furnaces, water heaters, etc. Without this protection, you can have backdrafting of fumes. Sounds like the automated damper you mention would have to be pretty smart to know when these random events are happening.
it is so nice to see somebody that knows wtf is going on. If this were a foam salesman, he would have told you any house without foam is too leaky. I actually test homes, and you are RIGHT! Alot of homes within the last decade are about right or too tight. thnks for the vid!
Through the band board or rim joist just above the top of the foundation. You will need a reciprocating saw and possibly a hammer drill if the exterior of the house is masonry.
What is the brand of that vent?

Will this system help with humidity?
