Darn humidity

[JOEPRO]

The humidity & mizzle is back again today after a few cold and dry days.

I gave in and placed some dehumidifiers in my garages. This type:



Those ones work well IMO. Overnight there are already a few drips inside the tray.

Then for my main back garage I went and picked up a new dehumidifier. A 20L capable one. It was on offer also at £150 which for a 20L capable machine is a pretty decent price.



I set it on auto mode and will let it run for a few days and see what the tank collects.

There is also a drain tube that comes with it so it can be piped through a wall to outside.

I am curious how power hungry it is too but not much can be done about that and it will only really be used a few months of the year.

There is a 24hr timer on it. Not sure how well it works but I may be able to set it so it only comes on at night when my house switches to cheaper economy 7 electric.

I added a cost checking power plug adapter. I programed it to the exact pro rata rate of my leccie.



I also see that after running a while the dehumidifier has detected my garage is high humidity and its up to top speed. Still only consuming 41watt at that.

I also hear water dripping into the tank already so will be interesting to see after a few days how much water it collects, if it can get the humidity level down and control it and how much is costs per week to run on average.

Where did you get that from? - Not sure I want to know, but could be useful

make sure you have no half drunk cups of tea or glasses of water in there,it will suck them 1st

I am on an economy 7 tariff. Primarily for my hor water etc.

So I simply took my econ 7 rate x 7 hours. And the regular rate x 17 hours.

Added these together.

Then divided by 24 hours.

Which gave me 30.25p per unit average. I think - I've had 6 whiskeys so will re check tomorrow!

Few hours and we are down to 60% from 79% in the worst bedroom.

This unit replaces an old Dimplex unit which works great but we thought might be costing us a fair bit.
I'm cleaning the old unit now and it's 410 watts versus the 190w of the new ebac unit. The new unit is also very quiet.

Old unit will be kept for drying laundry in another room.

41W seems low, power consumption wise. Presumably that's just the fan running. The compressor should add something like another 100W to that.

 

[Brad93]

Not looking good on the Ebac unit front.

Making a trickling water noise every five to ten minutes whilst running.

This continues for about 5 minutes after you switch it off with greater frequency. Unlikely this is water unless there is a controlled release of the collected condensation?

I reckon it might be the refrigerant because the poxy thing is useless, and has collected barely any water. Been on for another 12 hours with a target of 55% and it can't seem to get a small room under 64% with the door shut.

@JOEPRO i might return this unit and see if homebase have any more if your one is working well

Set it to 50 & see how it goes.

i'll give it a go

We have an ancient Matsui, remember them? We were given it about 20 years ago, still runs ok, no idea how much juice it uses as there is no makers plate on it. I bet it’s not very efficient though, but it dries the washing, got to be cheaper than a tumble drier.

Seems like normal behaviour. The condensing coils, on compressor type dehumidifiers, get down to well below freezing temperature, so the normal cycle includes several minutes of thaw time (compressor off, fan running) for the condensate to run off into the reservoir or drain. Dehumidifiers need a decent airflow for maximum efficiency, so check the air filter is not clogged, or even remove it, and see what happens.

it's brand new mate, literally set it up yesterday.

Don't know which model you have. Is there any way of being able to see the condensing coils? A build up of frost should start to be visible, at least on one end of the coils, after a few minutes of the compressor running.

Bear in mind that the dew point drops quite dramatically as relative humidity decreases, making it quite a bit harder to remove water from the atmosphere once relative humidity drops below 70%.

As an example, at 21degC, and 90%RH, the dew point is 19.3degC, and at 21degC, 60%RH, the dew point is now 12.9degC.

Seems decent yes. By this morning over 1L collected. £1.20 cost. Want to see what it's like when I get in from work which will be over 24 hrs of run time

Is there some shipping protective plastic somewhere blocking something ?
Maybe some packing peanuts or an errant broken corner of styrofoam packing is plugging the drain line ?

But he hasn't collected any water? And the thing is new, why would the folter be clogged?

It would be running over the floor after much less than 12 hours, like half an hour..

There's nothing in the thread to say it was a new dehumidifier, just that it was a replacement, heritage unclear, at the time of posting, until Brad mentioned it was new after my post.
