This rapid fall in temperature causes condensation, which needs to be drained - as much as 2 litres per hour for an efficient boiler.

If the condensate pipe has become frozen, the boiler’s sensors will detect that it has become blocked and prevent the boiler from operating. It will be angled steeply to avoid waste water from washing back up the condensate pipe, and if it is outside, it may be clad to add further protection from freezing. There’s just one more thing we need to cover before we step into the spooky world of leaking condensate pipes – their purpose.

e., the water produced from the condensation process, is collected in a sump before entering the condensate trap. Chances are BG cut corners and fitted overflow externally, then all you have to do is wait for it to freeze.

Condensate Pipe: What is a boiler condensate pipe? Boiler Condensate Pipe: What is a boiler condensate pipe?

Gurgling or bubbling noises: The trapped water inside the frozen pipe may create gurgling or bubbling sounds. Many of the solutions we have covered here can be carried out by a regular person with no plumbing or gas safe qualifications. We know that this can cost you a lot, so having a professional inspect your heat exchanger regularly will extend its life significantly. When water pipes are exposed to cold temperatures either outdoors, underground or in small spaces, you can protect them from freezing by wrapping them with heat tape.

Exterior: slide larger neoprene tubing over OEM line with only tip of line exposed, run ~2" over OEM tubing into wall, tape with plastic electrical tape at both ends to create insulating dead air space. Electric heat tracing, heat tape or surface heating, is a system used to maintain or raise the temperature of pipes and vessels. As BMitch suggests, routing the drain through trap would comply with plumbing codes and is the best solution.

Condensate Waste Pipes When Relocating 6 Vital Facts About Condensate Waste Pipes When Relocating

As pipe temperature falls the electrical conductivity of the semi-conductive core increases causing the tape to increase heat output. As much as it makes no difference to the untrained eye, it is still important to understand the mechanisms of a condensate pipe to prevent problems in the future. Of course, leaking water of any kind is not ideal in or around your home, leaking acidic water can cause more damage if it lands on something susceptible to corrosion. Any or all of your ideas will help, it largely depends on your climate and how long of a below freezing stretch you can expect. This condensing process sees the gasses from the flue undergo a substantial temperature decrease of somewhere in the region of 80 , which causes condensation to form, and that condensation needs to go somewhere.However, I had to go through an extra step, as my boiler had also lost a bit of pressure and wouldn’t start. Leaking at the joints of your condensate pipe can happen for a number of reasons, including the one we mentioned above.
