I watched this. It was of interest to me because I must run two dehumidifiers in my house and they use a ton of energy. Unfortunately, this desiccant dehumidifier would use even more energy. Hoping someday someone figures out how to build a more efficient one.
In the meantime, I think manufacturers need to build all dehumidifiers with a repeat cycle timer built in. I find it far more energy efficient to run for some period like 30 minutes till the humidity drops low — like 45%, then shut off for 60-120 minutes while the humidity slowly creeps back up until the cycle repeats. Most dehumidifiers work based on a humidity threshold and will constantly click on and off as the threshold gets crossed. In my experience, this uses a lot more energy. Being in a high cost state it is completely unaffordable.
I had the same torment when buying mine, for an office-shed that's just a swamp of English dampness.
I opted for the desiccant one as while it used more energy it does heat the space, and actually works better at cooler temperatures. Very specific to my needs as I'd imagine that's counter to most other use cases
Yeah - the video does clarify that the UK is one of the few places the desiccant one makes sense.
