Dehumidifier drying technique

Hello!

I was thinking about ways to dry out wood quicker, and I realized that I have a dehumidifier in my basement that is constantly spitting out low humidity, slightly warm air.

I put it under a storage shelf (followed instructions with enough room above the unit), rigged up some plywood to direct the airflow over my small basement wood pile, and waited.

After a few months, I found the wood has dried much faster than wood in the piles outside! (The wood in the picture is low right now, its usually piled up under the shelf, but I burned most of it)

Anyone else ever try this? Might be a good way to help dry out the wood you have stored for easy access during the dead of winter.

Worth slapping on a Kill-A-Watt meter and quantifying the power usage of doing that. Might be a good deal, might not, hard to say without data.

Idea has merit cost is a factor. Most common dehumidifiers have very poor performance below apx 60 degs F.

I already run the dehumidifier, my basement has mold issues and a lot of moisture, so it is killing 2 birds with 1 stone, to use it to also blow over the wood and dry that out as well
True... still adding that wood will raise the workload a bit (& moisture problems)

All that moisture removed from the wood is now in your basement air, requiring the humidifier to run longer to dry the air out. This might be a useful trick in an emergency to deal with unseasoned wood, but unless you've got very inexpensive electricity, it's probably not cost-efficient. Put the wood outside and protect it from the rain.

Not super-academic, but here's a decent explainer for dehumidifier operation. ...It isn't too terribly expensive, it would seem.

In my experience they cost about $1.00 per day to run.
