To expect my dehumidifier to actually work?

[Angelika321]

I bought a Meaco after looking at the Which? website. There's always condensation on the bedroom windows and my new curtains are showing signs of black mould spores.

It arrived last night and I set it up to use. Set the RH to 50. The indicator didn't go above 43 and it shut off after 30 minutes. I thought perhaps it was due to it being the evening and the heating had been on.

So I tried again this morning, after a night with 6 people in a 3 bed house. I thought the humidity would be much higher. It didn't go above 48. The water tank is bone dry.

What am I doing wrong?

It's probably just a dud. I have 2 different types of dehumidifier and both can pull some moisture out of the air, even when it's a dry summer day.

If you're trying to prove a point, just set it to full blast. If it's still not taking moisture out of the air, then exercise your consumer rights and get it replaced under warranty.

Quick update, the unit does work and it seems the humidity in the house is fine on a day to day basis.

However I used it while two loads of washing were being dried indoors and I was amazed at the amount of water I had to drain.

I think you're right with this theory, the windows in my bedroom are north facing and are always wet in the mornings.
