Question about ecofort ecoQ DryAir 35L Energy Saver

Yes, that is possible. It has a drainage opening at the back and with a 14mm inner diameter hose or pipe you can drain the water directly, the hose must run downhill and must not be kinked. A great device!!!

Here is the description on the ecofort homepage:

The ecoQ DryAir 35L can also be used for direct drainage, so the water tank no longer needs to be emptied and the dehumidifier does its job completely autonomously. All you need is the appropriate hose.

Yes, you can connect a hose (see manufacturer's page https://ecofort.ch/de..., Accessories tab).
The hose connection is at the back (just below the filter, very practical solution), see instructions https://ecofort.ch/de... , on page 4, point 8).
Incidentally, I am very satisfied with the appliance and would also like to drain condensation water directly.

I've never had to connect the appliance to a water outlet. I don't think it's necessary, except when used in a particularly hot and humid environment (tropical type).
