Why Replace your Leaking Boiler?

Heating accounts for close to 60% of the yearly energy bills in the U.K. Therefore, an efficient boiler is highly essential. If you have one that is leaking; that is an indication of a serious internal problem that could lead to significant damage to the heating system or your home. It could mean that either the seal or the valve is broken. Such a leak can potentially lead to rust and corrosion, and cause electric components in the system to short circuit. As such, boiler replacement should be done immediately.

Tracing Leak Problems

Most boiler leaks in the U.K. result from corrosion, broken seals, damaged valves, or faulty water pipe connections. Corrosion is the major cause of boiler leakage. Corroded tanks and pipes weaken and allow water to escape. If the corrosion is isolated to a valve, you may need to replace the single component. If the corrosion is widespread, the entire boiler will need to be replaced.

If after the installation, water starts to leak from the pipe fittings, it signifies that the boiler was improperly installed. If the damage is severe, you may have to replace the boiler. The blow off valve is a safety valve that protects the boiler from building up too much pressure. Normal pressure ought to be between 18 and 21 PSI, if it goes beyond that it could blow off. There are times the valve will leak, and people will assume it is defective. In some instances, the assumption could hold true, however, whenever your boiler is leaking, it is necessary to replace it even if there are other reasons associated with the defect.


Trying to inspect and replace your leaking boiler could put you and your family at risk of major complications. When hiring a plumber to replace your damaged boiler, ensure that the technician or gas engineer is a member of the gas safe register to be sure that the process will be done up to the U.K. heating system installation standards.
