    Prompt combi boiler repair St. Thomas

    Unlike conventional boilers that store water in a tank until needed, combi boilers are able to supply hot water immediately. In addition, one of the main advantages of this type of device is the ability to simultaneously provide heating and hot water to the entire building.

    Despite its many advantages, this system is still prone to malfunctions requiring extensive experience and high-quality tools to fix. For example, you may encounter a situation where the boiler does not light up. Based on our experience, several reasons, such as a damaged thermocouple, a damaged ignition wire, or an obstacle in the path of the ignition flame, can cause this problem. If you decide to repair your combi boiler yourself, you must solve the problem with the chimney, wiring or pilot light. Common risks during the renovation are carbon monoxide poisoning, burns, and electric shocks. To avoid this, trust our emergency boiler repair experts – we will quickly diagnose and replace damaged components in compliance with current building codes and safety regulations.

    What repair and maintenance services for boilers do we provide in St. Thomas?

    When it comes to boiler maintenance, finding a more experienced and expert team than ours can be a challenge. With many years of experience in the industry, we have learnt a thing or two about high-quality service. Our team has all the necessary equipment to fix your boiler:

    • Regular boilers (also called “conventional” or “heat-only” boilers since they produce hot water for central heating; however, they’re not intended for use in domestic settings, i.e. for showers and faucets;
    • Combination boilers are heating boilers that heat water for central heating.
    • System boilers – a system boiler is a closed system that requires only a boiler and a tank, whereas a conventional boiler may require a collector tank to supply hot water to the tank and maintain the water level in the radiators.

    We know how stressful it can be when your boiler suddenly breaks down or isn’t functioning at full capacity. That’s why our well-equipped team will be on site and perform boiler repairs in St. Thomas. We will aim to complete the repair within the same day because your peace of mind and comfort are important to us.

    What is the cost for boiler repair in St. Thomas?

    Due to the wide variety of repairs that a boiler may require, the average price may vary depending on the type of problem.

    Repairs may involve cleaning or replacing a single part, but the cost will vary depending on the component. For older boilers, it may be harder to find spare parts. This can ultimately increase the cost. The brand of boiler and its complexity can make a difference – large combi boilers can be more expensive to maintain than standard boilers.

    Since plumbing problems are among the most critical of household emergencies, we have developed a policy that offers reasonable prices and fast turnaround times.

    Is it better to repair or replace a boiler?

    Your heating costs will increase if you realise that you need a technician on a regular basis. There will come a time when it is more financially viable to replace the boiler than to repair it. The typical lifespan of a boiler is 10 to 15 years. It is recommended to replace any boiler that is more than 15 years old. However, this does not mean that you should wait 15 years to replace your boiler. On the contrary, you should consider replacing your boiler sooner, especially if it regularly needs repairs. After all, you don’t want to be stuck with a new boiler when it suddenly breaks down due to a major breakdown.

    On the other hand, you can significantly extend the life of your boiler by having it serviced at least once a year. Regular maintenance can reduce operating costs, extend the life of the equipment, and improve safety.
