Dehumidifier

Mary108

Hi all. I hope you're doing well

I'm intending to buy a dehumidifier and I wonder if anyone has any personal experience of these contraptions.

Which machine to buy and how expensive are they to run?

Thanks , as always

I have a few of both compressor and desiccant types. My big compressor one from Lidl (Silvercrest) draws around 230W when active and my Meaco DDL8L Junior desiccant one pulls 300W or 600W on the low and high settings respectively. I run my big compressor one overnight on cheap rate E7 and use the desiccant one for drying clothes and in any unheated rooms as it works better at low temperatures.

We have a Meaco 20L low energy dehumidifier. I've no idea how much it costs to run, but it is very effective.

Which brands/types do you use, please?

I've been running one in the workshop for many years. Something to think of but rarely mentioned is that the dehumidifier's job is to dry the air that's inside the building.  Any ventilation works directly against this aim, your freshly dried (at your expense) air goes off to the outside world, and  ew, wet, replacement air is drawn in.

So in my view they're best used without ventilation, which means special situations like unoccupied spaces. Or temporary use where doors and windows can be shut tight for the duration, maybe to dry laundry.

As for models and suppliers there are two main types. Dessicant machines can operate down to low temperatures, but use more power. Compressor types are more energy efficient, but you start to lose that advantage below 10°C or so.

These guys do both sorts and provide decent information, like performance at different temperatures and humidity (some just quote figures at 30°C/80% or something)

If I were you I would go with a compressor type, the Meaco ones are great. I have the older version of this one, it draws about 140w in laundry mode which is maximum extraction power.

Thanks! Do you find that 12Litres is sufficeint?

The air outside my house often has high humidity so I use a compressor-type dehumidifier to bring the air inside down to "normal" levels.  I run it just overnight when I get cheap-rate electricity.  Running for 7 hours at a stretch it can sometimes almost fill its 20 litre tank so I recommend you get one with a large water tank.  My model is an ElectriQ from Appliances Direct.  I have had it for two years now at it has run well, although the carry-handle broke when I was moving it.  It's supposed to consume 280 W and that must be about right.
