If you’re a house owner (and not only), you most likely wondered what is checked during a boiler service. And in case you didn’t know already, no matter the age of your device, it is necessary to do an annual boiler service to make sure it functions correctly and efficiently.

If you’re interested in this topic, you should keep on reading this article. You will find up next to our experts’ insights on the process of a regular boiler service. Let’s see what technicians check during maintenance!

A boiler service involves a lot of steps. Technicians have a thorough checklist so that they can observe and analyze how your device is functioning. There are seven categories of inspections that can tell an expert if there is something wrong with your boiler or not.

What Is Checked During A Boiler Service?

1. Visual Inspection

The first thing a technician will do during a boiler service is a visual inspection. This first step includes checking for water leaks, external damage to your unit, electrics status, quality of installation, or indicators of overheating.

2. Efficiency Testing

The second stage of a boiler service check-up is assessing its efficiency. A technician will run such tests based on the manufacturer’s standards. Mainly, the boiler will be ignited and run to assess if it works correctly. Also, the gas rate is established so that the technician can verify the optimal efficiency level of your boiler. Flue gas analysis and boiler tightness are the last steps of efficiency testing. These are meant to check for safety issues that might compromise your home.

3. Safety Inspection

Besides those two types of testing involving safety, a technician will assess several other aspects. As such, the boiler’s stability is verified to make sure it is fitted correctly, while the combustion and case seal is checked for optimum conditions.

4. Ventilation Inspection

A boiler service involves a lot of ventilation gas safety verifications. This means a technician will assess the state of the air vents, flues, or chimneys. Also, a spillage test is performed to verify the combustion process and ensure there is no safety hazard for your home.

5. Pressure Inspection

System pressure verifications are conducted at three points: the boiler, the inlet burner, and the gas meter. This is meant to identify issues with the gas supply, pipes, or any blockages in your boiler. Besides, the expansion vessel is inspected for pressure and current status.

6. Additional System Inspection

A professional boiler service will include several other system check-ups. One of these is a gas meter check. This is meant to verify how the emergency control valve functions so that you can easily use it in case of an emergency.

So, an annual boiler service is a necessary measure for any responsible homeowners. It can identify issues with your system in their early stages, which can save you a lot of money. Besides, frequent maintenance of this device can assure you everything is working safely. And, of course, regular boiler service can increase its lifespan, allowing you to use the machine for an extended period.
