What is a boiler condensate pipe?

The condensate pipe is the vessel that transports wastewater away from the home and down into the drains. The water in the boiler is boiled using flue gases and this process turns the water slightly acidic as it cools. This procedure improves a boiler’s efficiency, which is why all new boiler installations must use condensing technology because it reduces some of the wasted heat produced by the flue gasses.   

 

Where is the boiler condensate pipe?

The boiler condensate pipe is likely to be found outside, right above the drain. The condensate pipe is plastic, whereas the rest of the pipe is likely to be metal.

 

Why do boiler condensate pipes freeze?

It’s quite normal for condensate pipes to freeze because they’re external to the home, which means their exposed to the natural elements. During the winter months, this acidic wastewater is susceptible to freezing and when it does, the boiler becomes blocked and water gets backed up in the pipes.

When a boiler’s condensate pipe does freeze, a new boiler with a smart system will automatically turn off until the frozen condensate pipe has been adequately thawed. This prevents flooding and stops the boiler from becoming irreparably damaged.

 

How to thaw a frozen condensate pipe

Step-by-step method of how to thaw a frozen boiler condensate pipe:

  • Find the blockage – this is likely to be found in a curved piece of plastic piping, external to the home
  • Apply a hot water bottle or heating pack to the affected area – to warm up the frozen wastewater
  • OR pour hot water over the frozen section of the condensate pipe (but don’t use boiling water, this might crack or damage the pipe)
