Gledhill Hot Water Cylinder Problems

Gledhill is a name synonymous with high-quality water heating systems. Many homeowners have chosen Gledhill Envirofoam Stainless Steel Water Cylinders, believing that they have a longer lifespan than traditional copper systems. However, some have reported issues over time, including unexplained water leakage. If you have a Gledhill cylinder or are considering purchasing one, it’s essential to understand the potential problems and solutions.

The Problem

One commonly reported issue is water leakage from the cylinder. The scenario usually goes like this: A homeowner installs a Gledhill water cylinder and, after some time, notices water on the outside of the cylinder and the floor beneath it. While it may seem like an isolated incident at first, the problem recurs after a short period. This leakage is particularly pronounced when the homeowner has turned off the hot water heating while away from home. The cylinder’s design makes it hard to inspect directly, but some have observed water around the foam lagging where the immersion heater fits, even though the immersion heater cap remains dry.

Suspected Causes and Solutions

1. Fracture in the Cylinder: The water leak may be due to a fracture in the cylinder. When the water is heated, the fracture might seal due to the expansion of the cylinder. However, when the heating is turned off, the fracture may start leaking, especially if it is located near the immersion heater.Solution: If the cylinder is still under warranty, you can reach out to the seller or the manufacturer for a replacement. Many Gledhill products have a 10-year warranty, so it’s crucial to check your purchase details.
2. External Issues: Before concluding that the cylinder is the issue, it’s essential to rule out problems from external sources. Water could be running down from a loft or pipework, collecting around the cylinder. Another possible cause could be a malfunctioning ball valve in the cold water storage in the loft.Solution: Regularly inspect the loft and other related pipework. Ensuring these are in good condition can prevent water from collecting around the cylinder.
3. Condensation: Another plausible theory is condensation, especially when the hot water is turned off. While this may seem unlikely, under certain conditions, condensation can produce a surprisingly large amount of water.Solution: To determine if condensation is the issue, homeowners can recreate the conditions that lead to water pooling. For instance, one can turn off the hot water and check for wetness around every fitting. Using a paper tissue can help identify even slight moisture. Another method involves tying paper around potential leaking pipes and inspecting them for moisture or wetness.
4. Inappropriate Immersion: There are concerns about the compatibility of certain immersion heaters with stainless steel cylinders. If an unsuitable immersion is used, it might lead to problems down the line.Solution: Always ensure that the immersion heater is compatible with the type of cylinder in use. If uncertain, consult with the manufacturer or a professional plumber.

In Conclusion

While Gledhill’s hot water cylinders are known for their durability, like all products, they may face occasional issues. By being proactive and identifying the root cause of the problem, homeowners can ensure a long and efficient life for their water heating system. If a replacement or repair is needed, it’s always advisable to hire a trusted plumber to do the job. To find a reliable plumber, consider asking for recommendations or consulting online reviews.
