A well-functioning boiler is crucial for keeping your home warm and comfortable, especially during the colder months. However, like any mechanical system, boilers are prone to faults and issues over time. Understanding the common boiler problems and knowing what steps to take can help you address these concerns promptly. In this blog post, Hi-Tech Heating, your reliable provider of boiler repair and replacement services in Alton, Farnham, and Aldershot, will guide you through some typical boiler faults and how to handle them.


No Heating or Hot Water

If your boiler suddenly stops providing heating or hot water, it can be a frustrating experience. Before calling for professional help, check if the thermostat is set correctly and the boiler’s pressure is within the recommended range. Low pressure could be a reason for inadequate heating. If these checks don’t resolve the issue, it’s time to contact a qualified technician for boiler repair.

Strange Noises

Unusual noises coming from your boiler, such as banging, whistling, or gurgling sounds, are a sign that something is amiss. Often, these noises are caused by trapped air, kettling (due to limescale buildup), or faulty internal components. Attempting to fix these problems yourself could be risky, so it’s best to rely on professionals for thorough diagnosis and safe repairs.

Leaking Boiler

A leaking boiler is a serious concern that requires immediate attention. Leaks can result from issues like a faulty pressure valve, pump seal, or corrosion in the system. In such cases, turn off the boiler, isolate the electricity supply, and call a qualified engineer to inspect and fix the leak to avoid further damage.

Pilot Light Issues

If the pilot light on your boiler keeps going out or refuses to ignite, it may indicate a problem with the ignition system or a faulty thermocouple. First, check the gas supply to ensure it’s not interrupted. If the pilot light continues to malfunction, it’s time to seek professional boiler repair services to resolve the issue safely.

Boiler Replacement

Sometimes, older boilers experience frequent breakdowns and become inefficient, leading to higher energy bills. In such cases, it might be more cost-effective to consider a boiler replacement. A modern, energy-efficient boiler can not only improve your heating system’s reliability but also help save on energy costs in the long run.
