heating crawlspace with water to air exchanger
« on: January 29, 2012, 05:25:45 AM »
Hello Everyone

Has anyone ever tried to heat  their crawlspace with a hanging unit rather than pex under the floor joist??

As long as you were insulated at the end of joist bays and vents real good it may take awhile to warm up but I would think once you had it warmed up to say 90 or 100 degrees it would start to warm floors too?        Just curious if anyone has tried it            Thanks

may work but you would have to insulate heavily on both the walls and the ground. it would actually be a "hot room" a few grow lights and you would be in business :o

It would likely cause moisture problems too...

If you insulate the walls and ground good I would not be afraid to try it, oh welcome to the site.

Warm air above the ground will pull up moisture, not sure if it will cause you problems tho

I just fired up my boiler the first of the year and one thing I did with it is put a unit heater I salvaged off a job in the return line to heat my basement, which is about 2/3 crawlspace. If you have cold floors now, which I did, you'll like it. You don't need it that hot either or you'll be roasting yourself upstairs. Now that I have some heat down there I am seeing all the cold air infiltration I had before and am now taking care of that, with Great Stuff, insulation and Reflectix. I have always had moisture problems in warm weather so I've always run a dehumidifier. My house was built on bedrock and the full basement part blasted out so you may have different conditions on a dirt floor. I have spread tarps and plastic out over my crawlspace areas, mainly to make it more pleasant for crawling around.

I would be concerned with moisture too.  How is it protected?  Sealing it up will liekly generate a ton of moisture.  I would not be surprised if the floor started dripping, literally.  I know I had a situation with my attic where I had the vents block for a short time during construction and the ceiling litterally rained in there.
