Frozen Condensate Pipe for Kingston upon Thames homes
Condensing boilers push acidic condensate out through a small plastic pipe. When that pipe runs outside, a hard frost freezes the water in it, the boiler detects the blockage and locks out — often showing an EA, E1 or F28-type code depending on brand.
Thawing it gets the heat back on, but if the pipe is undersized, badly routed or unlagged it will freeze again next cold night. The permanent fix is re-routing internally where possible, or upsizing and properly insulating the external run.
When your boiler dies on a Sunday morning or a pipe bursts under the kitchen sink, the last thing you want is a national callout line dispatching whoever's "nearest" — sometimes an hour away. Maxfix Plumbing and Heating is based in Kingston upon Thames.

Frequently asked
Your questions, answered
Can I thaw a frozen condensate pipe myself?
Warm — never boiling — water poured along the exposed external pipe often clears it, then reset the boiler once. If it will not restart, or you cannot reach the pipe safely, call us.
How do I stop it freezing again?
Re-route it internally to a soil stack or waste where the layout allows, or upsize the external section and lag it with proper waterproof insulation.
Which fault code means frozen condensate?
It varies by brand — Worcester often shows EA, Vaillant F28, Ideal F1-type lockouts. The code is a starting point, not a diagnosis.
