The average home has a certain amount of fresh air coming in. Outside is often 50-80% here in the UK. Am I just spending 150 watts to constantly dehumidify fresh air?
Is it really dehumidifying the walls, furniture etc or just the new fresh air?
- malfist 4mo agoIn the US a lot of new buildings are build with ERVs or HRVs that allow deliberate outside air exchange through the central ducting without losing heat/cooling or without gaining/losing humidity
- bob1029 4mo ago> Am I just spending 150 watts to constantly dehumidify fresh air? Yes. And it's probably closer to 800-1000 watts if you have a reasonably large living space. Someone living in the UK is likely to find this extremely offensive, but it's quite common in Texas and Florida.
- gib444 4mo agoI had a feeling. The dehumidifier manufacturers (and their paid partner bloggers etc) insisting it takes weeks and weeks to start taking effect always struck me as odd - probably because even at full whack you're probably drying out the furniture etc at a very very very slow rate, because you're mostly in a losing battle drying out the fresh air. I wouldn't be surprised if energy companies were behind their popularity.
