A boiler service is important, especially for maintaining the overall performance and efficiency. The tests and checks being performed by the engineers during inspection ensure that the boiler is working safely and efficiently. Repair specialists of Boilers in Worthing advice to inspect the overall condition after 12 months from installation, and annually thereafter.

In this particular article, we will discuss in detail how boiler inspections are carried out.

Why Inspections Are To Be Carried Out At Frequent Intervals –

• Dirt and debris can clog up condense lines which can result in water flooding the boiler and sometimes damaging parts. We have often replaced boiler fans for this exact reason.
• Dirty heat exchangers lose their ability to transfer heat from the burner into the system water, so a full clean of the boiler maintains efficiency.
• Emissions of boilers can reach unsafe levels without checking and adjustment of the gas valve. This keeps the carbon monoxide produced by boilers within safe limits.
• Carbon monoxide alarms are recommended to everybody. The alarm will sound in the event of detecting a carbon monoxide leak. Without this, you would never know this odourless and lethal gas had escaped.
• Water leaks from inside the boiler can cause rusting, and if this penetrates the casing, the boiler is a write off. These can be addressed in good time, with regular servicing.
• Over time, flue seals and condense hoses inside boilers can fail, causing dangerous leakage of combustion gases.
• Gas valves can lose their ability to fully shut off the gas supply when the boiler is not in use, causing dangerous gas leaks to inside and outside the property.
• Cleaning of filters are carried out which gives the perfect opportunity to inspect the water quality and clear any debris collected by the filter. This may indicate that the inhibitor requires re-dosing.
• Casing seals can fail on room sealed boilers, meaning they are open to air in the room. This must be prevented at all costs, for safety reasons. Room sealed means completely sealed from the room.

Hopefully, these details are more than enough to let you know why boilers need inspection at regular intervals. If you are in need of more specification you can read on and know more.

Inspecting The Boiler –

A boiler service engineer will inspect the entire system,from the boiler to the adjoining pipes and radiators. Radiators are vented, system filters are cleaned, inhibitor levels assessed, and controls checked for correct operation. They will also check if any visual problem persists or not. Leaks and corrosion are common and should be addressed immediately. They will also test the overall performance.

The boiler casing will be removed, and they would ensure that there are no cracks or damage. Make sure not to takethe casing off yourself. Only a professionally qualified engineer should do this.

The Pressure is Checked –

If the system is a sealed system, as part of the service your system water pressure is checked and charged to the correct pressure (1.0-1.5 bar when cold). We will also ask how often the boiler is topped up. Regular topping up indicates a leak on the boiler or wider system, which will need addressing immediately. Topping up too often adds scale to the system, which inevitably gets deposited on the heat exchanger leading to a loss of efficiency, and if it remains unaddressed, a catastrophic blockage of the water ways, leading to excessive noise, over-heating, and eventually boiler failure.

The Essential Parts Need Proper Cleaning –

If required by the manufacturer’s service instructions, professionals inspecting boilers Worthing will also check the heat exchanger along with the combustion chamber. Checking these parts is essential so that the boiler remains safe and does not suffer a loss of efficiency.

Checking The Expansion Vessel Pressure –

If the boiler system is sealed it requires an expansion vessel to accommodate the expansion of the water as it heats up. If the pre-charge in the vessel drops, the system water pressure will rise excessively and this leads to issues with pressure relief valves, automatic air vents, and the issues associated with excessive topping up listed above.
