When running a dehumidifier with a drain hose....

[zed4]

...can the hose run uphill?

Apologies if this is a daft question, there's nothing about it in the instruction manual.

The boot in my tvr is wet, due to a faulty boot catch (now fixed) and I'd like to dry it out. I've just bought a decent dehumidifier and it's done a good job of drying the car and the garage out overnight.

Now I'd like to put the dehumidifier in the boot (with the boot lid open) and run the hose out the boot and out the garage door, as the water tank on the dehumidifier fills up too quickly. So, will it matter if the drain hose runs out from the bottom of the dehumidifier, up to the boot opening and then back down, outside the car and out under the garage door?

Obviously water can't flow uphill, but will it condense at the top of the hose and run out down the downhill section of the hose, or is that wishful thinking?!

Also, is there a maximum length of hose dehumidifier work with? I'd like to rig it up in my garage permenantly with a drain hose, this may involve dipping the hose down under the door and bringing it back up again slightly too.

Thanks,

Dan

I tried it for a while and it seemed to back feed and fill up the tank, as suggested above. I've decided to use the integral tank whilst it's in the boot.

Ps. I can't shut the boot as the vent would be restricted by the boot lid.

The car is going to be sat in a heated and dehumidifier garage Monday to Friday anyway. I leave the boot and doors open to air it out.

I ran it overnight on the internal tank. It was just about full when I checked on it this morning, and the boot was very nearly dry. There was a wet patch just behind the dehumidifier.

Now I just need to sort out a longer drain hose so I can rig it up permanently in the corner of the garage.
