Central Heating Leak Repair: How to Seal Pipes & Joints

The central heating system is a vital part of any home and building. So, what happens when there’s a leak? A leaking central heating system can be a frustrating problem to tackle, especially if you don’t know anything about C-Tec’s revolutionary sealant – Miracle Seal. Miracle Seal forms water-tight seals in no time and acts as the perfect solution to central heating leaks in the pipes and joints. Before we get into how to seal pipes and joints in your central heating system, it’s worth knowing how these leaks happen in the first place.


Causes of central heating leaks

Chemical corrosion is a common cause of central heating leaks, whereby an acidic solution formed by the crystallisation process (whereby the constantly heated and cooled water in the system strips the zinc from the copper pipes), attacks the weaker parts of the system – which is usually the pipe joints.

Some other causes of leaks in your central heating system include general wear and tear over time, a worn seal, and poor jointing. If there was a recent freeze, this can contribute to a leak during the thawing process. Whatever the case, sealing a leaking central heating pipe, fitting, or joint is easy when you’ve got Miracle Seal to do all of the hard work for you.

Its developers realised that the world needed a new leak sealant that could form water-tight seals without clogging the system and thus, Miracle Seal was born. Miracle Seal effectively seals water leaks throughout the heating system without causing any blockage. Its non-adhesive based, which means it will never clog the system, something that other polymer-based sealants find impossible to achieve.
