Boiler Servicing involves checking the appliance to ensure it works properly. This is done by an engineer who is Gas Safe registered.
They will remove the boiler casing to take a look at the internal components. They will then create a report listing all the tasks they have carried out.
One of the main reasons to have your boiler regularly serviced is to prevent carbon monoxide poisoning, which can be a silent killer. Carbon monoxide is an odorless, colorless gas that can build up in your home and can cause symptoms such as headaches, dizziness, and fatigue. A CO detector can help with this as it will sound a warning and warn you of any increase in levels of CO. It is recommended that you fit a CO detector in every room where there is a fuel-burning appliance and test it weekly to ensure the levels are not increasing, if they do then you need to call your emergency heating engineer as soon as possible to get the problem fixed before the levels become more serious.
When the registered engineer is carrying out the boiler service, they will visually inspect the boiler to see if there are any obvious faults or damage. They will also check the flue passage to make sure there are no obstructions and that it is correctly fitted. It is also important to keep the vent pipes clear of any clogs and to clean them regularly.
After checking the flue, the engineer will look at the boiler controls and ensure they are functioning properly. They will then take off the casing to check inside and ensure there is no damage to the burner, heat exchanger and any other components. They will also check the air intake, combustion chamber and case seal. Modern boilers are designed to be room sealed but this is only effective if the case seals are intact so these will be checked too.
Once the boiler has been shut down and drained of water, the engineer will dismantle it to check all the internal parts. They will check for any signs of corrosion or scale build up. They will then drain the boiler and dry it out, ready for reassembling. Before they do this though they will check the pressure gauge and sensor readings to make sure they are within the correct range. They will also empty and clean the condensate trap as this can build up with sand-like debris from the products of combustion. They will then reassemble the boiler and perform a combustion test to make sure the burner is firing within its specification. Once they have completed all the checks they will issue you with a Gas Safety Certificate which includes the engineer’s name and Gas Safe number as well as all the results of their inspections and tests.
When performing boiler servicing, engineers will check that all controls are functioning properly. They will also inspect and put back any controls they alter. They will also look at combustion air vents and flue gas venting to ensure there are no signs of leaking, blockages or wear. They will also examine the control panel display to make sure the temperature and pressure readings are within range. They will also make note of any errors that might need to be communicated to the client.
Dirt can build up in the boiler control systems. This can cause problems with the sensors and switches that control the boiler, causing them to fail. To avoid this, it is recommended that a filter be used in the heating system to catch any dirt and debris that may enter the system. This can be done easily by simply removing the front panel of the thermostat.
The low-water fuel cut-off device in a boiler should be cleaned regularly to prevent it from failing. This is especially true if the boiler is located in an area that is prone to condensation and water leaks. It is important to blow down the float chamber and water columns on a regular basis in order to keep them clean. Failure to do this can result in sluggish circulation, poor combustion and lower heat transfer efficiency.
It is also a good idea to clean the burner and flame sensor on a regular basis. These can become clogged with deposits and cause the boiler to fail to ignite. It is recommended that these parts be cleaned with a soft brush or cotton buds. If the burner sensor is dirty, it can cause carbon monoxide poisoning.
Often, boilers are tucked away in confined areas of the home, making them hard to get to for inspection. It is a good idea to walk around the boiler room and make sure it does not have any combustible materials stored nearby. This will help to reduce the risk of fire and reduce the chances that the boiler will fail due to lack of maintenance.
A boiler service includes checking the pump to ensure it is working correctly. This is done by gently tapping the pump – it should make a light vibration and be warm to the touch if it has power. If the pump isn’t working, it can usually be replaced by an engineer – however, it is important that a multimeter is used to check across the red and black terminals to see if there are any voltages present (the fuse rating should also be checked to ensure it can handle the load being applied).
The safety valve on a boiler is another vital component that needs to be in good condition to work properly. The safety valve should be able to hold the maximum pressure of the boiler and prevent water leakage. In order to ensure that this is the case, it must be checked regularly for internal corrosion and cleaned as necessary.
During a boiler service, the heating engineer will also test that the gas supply is connected and sealed correctly. They will also test the combustion chamber to ensure that it is safe and secure, as well as ensuring that there are no airflow restrictions around it.
It is also important that the boiler’s circulating pump is working correctly. This is a vital part of the system that pumps water through to the radiators, so it is crucial that it is in good working condition. A faulty circulating pump can lead to poor heat distribution and increase running costs.
A boiler service is an essential part of a landlord’s duties under the Gas Safety (Installation and Use) Regulations 1998. The regulations state that the boiler must be serviced every year to keep it working safely and efficiently. Landlords should also ensure that the boiler’s occupants are aware of the gas safety checks carried out by a registered engineer.
If you are a landlord who owns a property and would like to arrange a gas safety inspection, please contact us today. Our team of friendly experts will be more than happy to help you.
Your boiler needs to be at the correct working pressure in order to operate properly and efficiently. This is why checking the pressure is one of the most important elements of boiler servicing. If your boiler isn’t at the right pressure, it can put strain on your heating system, leading to problems such as the boiler overheating or water hammering in the pipes. As part of a boiler service, the engineer will check the pressure across three different points in your home to ensure it’s at the correct level.
The most common method of checking boiler pressure is by looking at the pressure gauge on the front of the boiler. This will show either an analog or digital display. An analog display will have a needle that moves around a dial, while a digital display will be either LED or LCD and could have additional information displayed alongside the pressure reading. The ideal pressure range for your boiler will be shown on the gauge, with two coloured sections showing the maximum and minimum working pressures.
If the gauge shows your boiler is at a high pressure, this may be because it’s overdue for a top-up, or because it’s been left open after maintenance or accidentally knocked out of place. If this is the case, tightening the pressure relief valve will lower the pressure. Alternatively, you can also try bleeding your radiators to reduce the pressure in the system. If you’re unsure how to do this, consult your user manual for instructions.
Regular boiler service is the best way to keep your boiler in good condition. Not only will it prevent damage to your boiler and its internal parts, but it’ll also help you stay safe by detecting any carbon monoxide leaks – which don’t have an odor and are hard to detect. Plus, it’ll save you money on energy bills and give you peace of mind that your boiler is working correctly. The most important thing to remember is that boiler servicing should only be undertaken by a qualified heating engineer, so make sure you book in your annual appointment.
