Why does a heatpump have a drain?
Depending on whether or not a unit is on heating cycle or cooling cycle,
the indoor unit (on cooling) or outdoor unit (on heating) will absorb
moisture from the air. This water has to drain away. The indoor unit
is fitted with a condensate drain hose and the outdoor unit has a drain
pan with punched drain holes. In some cases, if it is not possible to
install a drain pipe with adequate fall, a drain pump has to be fitted
to the indoor unit. This allows for the condensate to be pumped to waste.
