I bought a small desiccant-type dehumidifier from the middle aisle of Lidl last week as I was planning to use it in an unheated conservatory where I have laundry drying. I already have a larger compressor-type dehumidifier that I use in the house but chose the desiccant one as it should work at all temperatures. But it barely works - I’m getting 7-8 ml of water in the collection tub per hour of running at 60-70% RH. Have tried it in a small room indoors and it’s no better. Packaging says it should extract 600ml per day so I’m getting less than a third of that. Also, it’s not giving off any noticeable heat into the room even after 4 hours of running, unlike my compressor model. Have I got a broken one or are they generally just crap?
