I have a leak from the condensation line on my heat pump.

On a hot day you could get 3 – 5 litres of water from the condensation line – just like an air conditioner. The hotter the day the more you should expect, in fact in summer it could be 3 – 4 litres per hour! If yours is consistently running more than this then there may be an issue for a plumber to investigate.

If you can take photos or video of where the leak is coming from it can help to diagnose the issue remotely.
