Boiler Service & Repairs Colchester

Boiler Servicing

Boilers work extremely hard every day to provide hot water and heating. Boilers burn fuel; as a consequence, internal components become dirty and need cleaning.

Working parts, such as valves and seals, can also wear over time.

A service allows all internal elements to be cleaned, tested and inspected, so your Boiler runs more efficiently, wasting less fuel.

Servicing ensures your Boilers is safe to use and the flues expel all unwanted gases as they should, so there’s no risk of carbon monoxide poisoning.

Servicing validates home emergency cover policies, ensuring you’re covered in the event of Boiler failure. Serviced Boilers are far less likely to break down than unserviced boilers.

What Does A Boiler Service Involve?

Every part of the Boiler is cleaned, inspected, and tested during the service as per the Boiler manufacturer’s instructions. Here’s an example of a typical Boiler service…

1. The Boiler case is taken off and inspected for water and corrosion, in case there’s a leak in the Boiler somewhere. The case has been cleaned appropriately inside and out.
2. Cleaning of all internal components commences before testing
3. The seals and pipework is inspected for leaks. New seals are fitted if necessary. Loose connections are tightened
4. The water flow rate and pressure are tested. Pressure’s corrected if necessary. If we find a problem with pressure or flow, we’ll investigate further
5. Safety and relief valves are tested. These valves prevent Boiler damage if a fault ever occurs
6. Gas burner pressures checked and adjusted if required. Next, we use a gas meter to check the gas rate. Testing and adjusting ensure the correct amount of gas is burned
7. The flues were visually checked for damage and blockages. Flue gas analysers are used to measure carbon dioxide, carbon monoxide and oxygen. This ensures there’s no risk of carbon monoxide poisoning
8. The ventilation is checked and tested to make sure enough air is present for every cubic meter of gas burned
9. The Boiler and pipework are tested to ensure there’s no leaking gas
10. After servicing the Boilers, put them back together and switch them on. Our engineer will make sure it’s running correctly and your radiators are heating up properly
11. Our engineer may make some recommendations, so you get the most out of your heating system. Common recommendations include carbon monoxide alarm installation, condensate pipe insulation (to prevent breakdown) and Powerflushing (if your system has sludge)
12. The engineer tidies up and writes a service record for you to keep. This record proves a Gas Safe Registered engineer has serviced your Boiler

Boiler Repairs

Modern-day Boilers are incredibly reliable. They work hard day after day, year after year, but sometimes a fault develops.

Faults are quickly rectified by our experienced engineers who’ll locate the fault and replace the necessary parts, getting your Boiler back up and running again.

Give us a call if you’re experiencing any of the following faults.

Boiler Switches Off Regularly

Once on, the Boiler should stay on. If your Boiler keeps switching itself off, then there’s a fault present. Don’t keep switching your Boiler on, get it inspected. Damage may occur if the fault is ignored.

Low pressure causes the switch to turn off. Sometimes the repressurising of the Boiler is all that’s required.

If it’s impossible to sustain pressure, then there’s either a leak, a faulty seal or a broken safety valve.

Leaks can occur in several places, and the engineer will locate and replace the leaking part.

Other causes could be a blockage (usually caused by limescale) or a faulty pump.

Leaking

Boilers should be watertight, and leaks always indicate an issue. Switch off a leaking Boiler and don’t use it again until an engineer has inspected your Boiler.

Many leaks can be rectified quickly and once repaired. Your Boiler will run properly again.

Never ignore a leak left long enough as it will damage the internal parts of your Boiler, including electric wiring.

Pilot Light Keeps Going Out

The pilot light must be on for the Boiler to operate. A safety device called a thermocouple regulates the flow of gas to the Boiler.

If the pilot lights blow out, the thermocouple automatically cuts the gas supply (so there’s no gas leak).

Faulty thermocouples will continuously cut off the gas supply, causing the pilot light to extinguish. Replacing the thermocouple is a straightforward solution that will resolve the issue.

If the thermocouple is in order, then there may be an issue with your gas supply.

Loud Noises

Limescale and debris are inevitable by-products of central heating systems that, in some circumstances, can cause problems within the Boiler.

If a large enough piece of limescale gets trapped in the heat exchanger (the device that converts heat from gas to water), then it’ll make a noise similar to a boiling kettle. This is known as ‘kettling’.

Get your Boiler looked at ASAP before damage occurs. Any strange noises coming from a Boiler should be reported to a gas engineer as they are an indication of a fault.

Boiler Won’t Switch On

If your Boiler doesn’t switch on at all, there may be a defunct fuse in the switch. In this instance, a replacement fuse will get your Boiler running again.

In harsh winter conditions, you may have a frozen condensate pipe, which removes excess water produced by your Boiler.

Uninsulated pipes can freeze, preventing the Boiler from functioning. We’ll defrost your pipe and insulate it adequately so it won’t freeze again.

Faulty thermostats will prevent a Boiler from switching on. Thermostats are straightforward to replace.
