Efficient basement dehumidification? (self.homeimprovement)

submitted 2 years ago by bbbbb to c/homeimprovement

I have 2 standard freestanding units in my basement and crawlspace running 24/7. I want to get something more energy efficient, will last a while, and that's easy to maintain. I am considering an Aprileaire dehumidifier. Based on this https://www.energystar.gov/productfinder/product/certified-dehumidifiers/results it would appear they have a high efficiency rating. Does anyone have experience with these or recommendations on solutions?

So, good question, the previous owner did install a vapor barrier covering the basement and crawlspace, so there is some other mitigation in place. The current unit came with the house - HOMELABS HME020031. It keeps humidity down fine, but the pump is broken, so I'd like to replace it with something that should last for a while and hopefully run a little lighter on electric cost.
It seems it has a rating of 1.9L/kwh, whereas the aprilaire is 2.3L/kwH, so I suppose about ~20% more efficient. My other thought was they seem to have a better warranty so if something fails then I don't need to replace the whole unit.

Sizing up is one way to get efficiency. Another is switching to 240volt from 120volt if your unit supports it.
