Boiler Service & Repairs Stanford Le Hope

Boiler Servicing

Boilers should be serviced annually to ensure optimal efficiency, lower fuel bills, protection from boiler breakdown and carbon monoxide poisoning, and to validate your home insurance and Boiler warranty.

Boiler Servicing involves a stringent procedure undertaken according to the manufacturer’s instructions. Here’s what a Boiler service typically involves.

1. The outer casing is inspected for leaks and corrosion. Water droplets or damage to the case is an indication that the seals are broken or a pressure valve has failed. The outer casing is removed and inspected on the inside, also. If the casing is damaged we may offer a repair or replacement.
2. All pipework is inspected to ensure connections are tight and there’s no leaking.
3. Next, we check the seals for corrosion and tightness. Loose connections are tightened where necessary.
4. The Boilers switched on, and the pressure is checked. If the pressure’s incorrect, we’ll adjust it to the optimal level. Pressure checking also allows us to establish if there are any potential blockages in the system. Blockages cause fluctuating pressure, which will cause continuous switching off.
5. Working components are cleaned. Clean components enable the Boiler to run smoothly, and accurate testing and correct adjustment of components, such as the gas burner, are crucial.
6. A gas rate check is undertaken to ensure the Boiler is burning the correct amount of gas per hour.
7. The levels of oxygen, carbon monoxide and carbon dioxide are checked with a flue gas analyser. This test shows the efficiency and safety of your Boiler.
8. The Flue is also visually inspected, ensuring it is fitted properly, functioning correctly, and poses no risks.
9. Ventilations checked to ensure the Boiler is getting the required ten cubic meters of air for every cubic meter of gas burned.
10. All the Boiler safety devices (which prevent damage in a Boiler failure event) are visually inspected and tested.
11. The Boiler and pipes are tested for leaking gas.
12. Once the service’s finished, the case is refitted, and the Boilers switched on. The engineer will check that your radiators are getting hot and bleed them if necessary.
13. A service record is written, keep this in a safe place. You may need to produce the record if you need to use a home emergency cover or claim on the manufacturer’s warranty.

The engineer undertaking the service may offer recommendations, so you get the most out of your Boiler.

Boiler Repairs

Over the years, our engineers have repaired all kinds of Boiler faults and problems.

Here are some common Boiler faults. If you’re experiencing any of these issues, get your Boiler looked at, even if it’s still working.

Never ignore any defects or issues; they will eventually turn into bigger and more expensive problems to solve.

Boiler Keeps Switching Off

The first thing to check is your Boiler pressure. Sometimes the repressurising of the Boiler is all that’s needed.

If boiler pressure continues to drop, then there may be a blockage in the Boiler or system, which is restricting pressure and causing the Boiler to switch off continuously.

If this is the case, one of our engineers will locate and remove the blockage.

Faulty thermocouples or a pump can also be causing your Boiler to switch off. The Thermocouple controls the gas supply entering the Boiler, an essential safety device which will cut off the supply in the event of a fault.

If your pilot light keeps blowing out, causing the Boiler to stop, then the Thermocouple may need adjusting or replacing.

Faulty pumps can be reset to the correct settings, unblocked or replaced if necessary.

Strange Noises

Strange noises are caused by many issues, such as broken valves, excessive air, overworked/failing pumps or limescale blockages in the Boiler.

Central heating systems should be Powerflushed periodically to break down and remove the buildup of limescale and other debris.

Sometimes large pieces of limescale get lodged in the internal components, and the Boiler will make a loud noise that sounds like a boiling kettle. This issue is known as kettling.

Kettling can cause the Boiler to overheat, and the Boiler’s built-in safety devices will shut the Boiler down, preventing it from functioning.

Always get strange noises coming from your central heating or Boiler looked at by a Gas Safe registered engineer.

Leaks

Leaks are a common Boiler fault and can be caused by several internal issues, such as worn seals, broken pressure valves or corrosion in parts such as the heat exchanger.

Leaks need attention if water reaches any of the electrical wiring, the Boiler will short-circuit and fail. Leaks can also damage parts of your home, such as flooring and cupboards.

Leaking Boilers are usually solved by replacing a faulty part making your Boiler watertight and safe to use, usually for years to come.

These are just a few faults other faults include frozen condensate pipes, radiators not heating, and Boilers not switching on at all.
