Boiler’s condensate pipe drips constantly even when boiler is off

Safety first: Condensate is mildly acidic; avoid prolonged skin contact.

• Confirm boiler is off: Ensure there is no heat demand and the boiler is not in frost protection mode.
• Observe discharge: A small amount of residual dripping after shutdown can be normal, but continuous flow is not.
• Check for mixing with system water: If the discharge is warm or discoloured, it may indicate a leak from the primary circuit into the condensate path.
• Professional inspection: A Nibe technician should inspect the Nibe condensate trap and primary heat exchanger for leaks or cracks.
