What is Boiler Commissioning? A Gas Engineer’s Guide

What is Boiler Commissioning?

Boiler Commissioning Regulations

A gas engineer is responsible for conducting the necessary tests and evaluations in the commissioning process. They must be gas-safe registered, which ensures that they are up-to-date with the necessary certifications and familiar with the various boiler systems, common problems, and legislation.   

Steps in the Boiler Commissioning Process

The boiler commissioning process is a comprehensive set of steps that includes pre-commissioning checks, safety checks, function tests, and performance analysis. The time it takes to complete varies and can take anywhere from a couple of hours to a full day, depending on the size of the unit.

Step 1: Cleanse the System 

After installation, the first thing to do is flush the system as per the manufacturer’s specifications. This is key for preventing black magnetite from flowing through the system, which if left, can reduce the system’s efficiency and increase running costs. 

Step 2: Add a Corrosion Inhibitor

Once the system is cleaned, it’s time to add a corrosion inhibitor. This prevents corrosion and hydrogen gas from entering the system and reducing its lifespan, and ensures the owner can get maximum value out of the boiler.

Step 3: Test the Gas Flue

The next step involves testing the gas flue and recording the analyser readings. This test ensures the boiler is burning gas safely and at optimal levels, meeting both the manufacturer’s specifications and the regulatory requirements.

Step 4: Test Performance and Set Output

At this point, you can test the boiler’s performance and set the gas output for the household’s needs. The output is adjusted according to the size of the house and the number of radiators, ensuring that the boiler isn’t using more energy than required. 

Step 5: Gas Tightness and Let By

These two tests are critical safety checks. The gas tightness measures the flow and pressure within the pipes, and the let by test examines if there is any gas leaking when the valve is switched off.  

Step 6: Register Your Guarantee and Complete the Task

Lastly, you must register the boiler’s guarantee for warranty purposes. This is done through the manufacturer’s installer apps and provides homeowners with long-term coverage and financial security should something unforeseen happen.

Before completing the task, it’s good practice to build customer relationships by explaining what has been completed during the boiler commissioning process. It’s also worth informing the customer of how the boiler guarantee works. 

What are the Potential Hazards?

The main risk of not having a boiler commissioned is the potential for gas leaks, which can be extremely dangerous. Having an expert gas engineer expertly commission a boiler and approve it for use gives the customer peace of mind.

However, other consequences unrelated to safety are likely to occur if a boiler isn’t commissioned. For example, without proper commissioning, a boiler will consume more energy than necessary, leading to more frequent and costly repairs and high energy bills. The system will also become much noisier as a result of having to work harder. 

What Happens if a Boiler is Non-Compliant?

A non-compliant boiler may lead to penalties and prosecution for the homeowner and potentially the gas engineer if processes are not correctly followed. Any issues that make the boiler non-compliant need to be repaired as soon as possible.
