Dehumidifier how long to start extracting water?

[SpiderPeter]

We had a dehumidifier delivered this morning never used one before. How long until you see water in the tank when using a dehumidifier in your home? It’s been on two hours and not really collected anything as of yet.

I would say ours would have some water in the tank by then but not much

They start pretty much instantly. It does depend how much moisture is in the air, though. I only use mine to dry washing and it would have a lot of water in it after two hours.

Does it tell you how humid the room is that you have put it in as it depends on this

Thank you, wondering if this one is faulty then or the hire shop have set it up incorrectly. It’s an industrial one, we were flooded after a roof leak and after two hours there is not a drop in the bucket. The house is damp viable damp on the walls/celling/concrete floors etc.

Is it making a noise? What setting is it on? If it's on automatic and the room isn't very damp it might not be working

It is best to let them stand for a while after delivery. Unplug it for 24 hours, then run it for 24 hours. Cold temperatures will affect how much it collects unless it is the desiccant type.

They start instantly, but what you see will very much depend on how much damp there is in the surrounding area anyway. If there isn't much then obviously it will be a long time before you see much evidence.

I think you can also set some of them for how sensitive you want them to be.

Ignore my post. I didn't see your follow up before I started typing. Contact the company.

I have no idea how it works, they left no instructions. There is a red button for on/off and a dial no digital display. It is industrial sized and designed for flooding drying out buildings so big and powerful.
I might have to see if I can find the instructions online.

Are you putting it in one room with the door/windows closed or in a hallway?
Will work better in one confined space at a time.
And I really dont mean to sound patronising but have you opened the 'flap'?... cos I didnt the first time I used mine!!🤦🏼‍♀️

OK, then I would have thought you should have plenty in the tank and be having to empty it regularly.

Contact the supplier and get them to come back.

@Bonbon21 what flap?

The compressor ones (which is almost certainly what you've got) are less efficient at low temperatures (below 10C). Also, you should have the doors and windows closed in order for it to work best.

I agree with others, you probably should see something in the tank after several hours.

ETA: some of them have an option to drain in to a hose/external outlet instead of the internal bucket - have a look for that - may be a small valve that needs closing/opening...

It’s this one, it’s set up to collect in a bucket.

Water can't flow uphill, so you need the hose to be working with gravity in to the external bucket - ie flowing downwards for the machine outlet. You may need to raise the level of the machine if the bucket is tall.

Sorry.. didnt realise it was an industrial one....

@CranfordScones thank will have a look now. You could ring water out of the carpet underlay when it was removed earlier and can feel its damp. The heating is on and set to 20.5 and windows are closed but I will try closing the rooms off.

Not much after 2 hours

Loads after 12 hours

Windows and doors to the room need to be closed for it to work it's best

We use ours to dry washing so it fills up fairly fast, but in an empty room it wouldn't have much after a couple of hours.

Found a manual online, moved the bucket, straightened out the hose and now it’s collecting water. A litre in the last 25 minutes
