Single family home in coastal California climate zones 3C (95062). The home is 1263 square feet with a small crawlspace at 18″ in height.
I’ve just completed my encapsulation project. The vents have been sealed shut with wood blocks and spray foam. A vapor barrier has been placed on the floor and fully taped to the all the posts and stem wall. I have a remote data logger in the crawlspace so I’ve been able to monitor the temperature and relative humidity.
After encapsulation, my relatively humidity is far more stable. However, it seems to enjoy staying at 60-65%. I’ve settled on putting in a dehumidifier as I do not like mixing the crawlspace air with my house air for a variety of reasons.
My problem is finding a reasonable dehumidifier. With 1,900 cubic feet, I have a relatively small crawlspace with, I believe, relatively small dehumidification needs. All the purpose-built crawlspace dehumidifiers I see seem way overkill (and wallet killing as well!) Other dehumidifiers, however, won’t physically fit as their designs are usually about 24″ tall.
Am I missing something here or am I going to have to purchase a $1,000 dehumidifier for my relatively small problem? Alternatively, am I fretting unnecessarily about my humidity levels?
