The water can indeed be exhausted vertically upwards. Ideally, there should be a decline in the exhaust hose to stop condensation building in the exhaust and running back into the dehumidifier. However, there will be instances when this is not possible nor desired.
If the exhaust length is short, condensation may be unlikely to build in the exhaust hose at all. Longer lengths or units used in colder climates may need the exhaust hose lagged with insulation or a condensation trap used on the exhaust hose put into the hose.
Ducts can be longer than prescribed but performance will decrease with additional length due to air resistance. An solution to this issue, if air flow or extraction performance is a concern, is to use wider diameter ducts to increase the air flow using larger diameter ducts than that are prescribed and suitable couplings.
The wet air exhaust is waste water pipe size 41mm in diameter. This is readily available in DIY shops but sometimes referred to as 40mm Push-Fit pipe and connections. The larger duct diameter is 125mm a standard duct size that is used with some venting kit manufacturers and often used for tumble dryers in flexible and hard duct options also widely available from DIY stores.
