I have been asked to install a Powrmatic heatpump unit.
The drain will carry condensate all year round as it is a packaged indoor unit so my worry is that the drain may freeze up in winter when running in heating mode.
The pipe run is approx 8m all outside so i am debating to install a drain heater or whether to just lag the plastic pipe.
Any help would be appreciated. Thanks

Can you convert to a pumped condensate system?
Then pump it high indoors and use as near vertical as possible external in 32mm lagged pipe.

The drain outlet can only exit via the back of the unit. There is no option to alter it so the only way i could use a pump would be bring the drain back in and drop it into a tank pump in which case it would be easier to run it outside.
The installation manual tells you to install the drain in between the cavity in countries where the weather is cold!!
