Does anybody know what a reasonable temperature for a crawlspace would
be? I recently put two dehumidifer units in my crawlspace (along with
a couple box fans to circulate air), as I've had major problems with
moisture down there. I have all the crawl space vents sealed.
However, the temperature in the crawlspace is now running about 8-10
degrees hotter than it had been. It was running around 68 degrees.
Now it is consistently up around 76-78 degrees. I guess this is
because the dehumidifers heat things up. The humidity level in the
crawlspace is now under control, the RH has been staying around 45-47%
(it had been running around 80-90%). But I'm concerned about the
temperature running higher. Is this anything I should worry about?
What would be the ideal temperature and RH for a crawlspace?

Hi,
RH is function of temperature. So looks like nothing really changed in
your crawl space. My cabin has crawl space where furnace, water heater,
well water tank are located. It's cool in summer, warm in winter down
there and no moisture problem just with natural vent. Furnace draws
fresh air from outside thru insulated duct. The floor of crawl space is
dirt and it's dry, it;s almost dusty.
