Common Boiler Problems

No Heating or Hot Water

One of the most common boiler problems that homeowners face is the lack of heating or hot water. This can be a major inconvenience, especially during the colder months. The issue could be due to a faulty thermostat, a malfunctioning motorized valve, or a problem with the electrical connections.
