Boiler Service & Repairs Purfleet

Clearwater Boiler Service

Servicing is undertaken as per the manufacturer’s instructions and covers the following.

Competent, Certified Engineers

All Boiler servicing is undertaken by one of our experienced Gas Safe Registered engineers who’ll show up at your property at the agreed time and present the necessary Gas Safe ID.

Leak Checks

First of all, the Boiler casing is removed and inspected inside and out for corrosion, which tells us there’s a leak. We’ll establish the source and stop the leak by tightening a loose seal or replacing a faulty valve upon discovering a leak.

Pipework

Next, the engineer will check that the pipework serving the Boiler is tight, leak-free and corrosion-free.

Internal Cleaning

All internal Boiler components are cleaned. Cleaning helps the Boiler run more efficiently and allows for accurate testing.

Waterflow & Pressure

The pressure and water flow are checked and adjusted if required. Low pressure may be an indication of a blockage, which will cause issues such as constant switching off.

Safety Devices

Boilers incorporate safety devices to prevent damage if the Boiler experiences a failure and comes to an abrupt stop. Safety devices are checked and tested.

Gas Rate Check

A gas rate check is run to ensure the correct amount of gas’s consumed. The pressure of the gas burners is adjusted if necessary.

Flue Check

A flue gas analyser is placed inside the flue to measure the rate of carbon monoxide, dioxide and oxygen.

This test ensures the flues expel all excess gases properly, so we know your Boiler’s safe, there’s no carbon monoxide risk and no unnecessary waste in burnt fuel.

Ventilation

Boilers require 10 cubic meters of air per meter of cubic gas. We check the ventilation and ensure your Boiler’s getting the air required.

Boiler Test

Once the Boilers clean and the test are completed, the case is refitted, and the Boilers switched on to ensure it’s working ok.
The engineer will check that your radiators are getting hot and bleed them if necessary, as excess air will prevent them from heating entirely.

Service Record

Once the engineers completed the procedure, a service record is written. The record proves your Boilers been serviced by a gas safe registered engineer.

Keep the service record as you’ll likely have to present it in the event of a home insurance or boiler warranty claim.

Boiler Issues?

The older Boilers get, the more likely they are to develop faults. Boilers deal with heat and hot water daily, year after year, as such internal parts wear out and cause the Boiler to stop working correctly or altogether.

Faulty parts inside Boilers are adjustable or replaceable. It’s usually a case of locating the fault and adjusting or changing the part.

Competent Gas Safe Registered engineers must undertake all Boiler repairs.

Clearwater Engineers have been repairing Boilers in Purfleet for many years and will fix your Boiler quickly. Here are some typical Boiler faults we deal with on a regular basis.

Continuous Switching Off

If your Boiler keeps switching off, don’t just keep switching it back on, there’s a pressure or thermocouple issue that needs looking at.

The most likely cause is low pressure. Low pressure occurs when there’s a leak, blockage or failing pump.

Leaks

Leaks are easy to identify and usually simple enough to rectify. Loose connections are tightened, and worn seals are replaced.

If your Boiler keeps switching off, you may have noticed dripping or corrosion around the Boiler casing. Left alone leaks can short circuit the electrics of your Boiler and cause damage elsewhere.

Blockages

Limescale occurs in central heating systems. Sometimes large pieces of limescale get blocked in the pipes or, worse, the heat exchanger.

Blockages will cause a pressure drop, and if the heat exchangers blocked, you’ll get likely year a weird noise similar to a kettle boiling.

This phenomenon, known as kettling, can cause expensive damage in the form of a new heat exchanger. Best to get the blockage removed before damage occurs.

Faulty Pumps

Pumps that are running at reduced pressure due to a worn motor or leaking seal need replacing. Pump repair or replacement is a straightforward procedure that’ll get your Boiler back running to the correct pressure.

Broken Thermocouple

The Thermocouples regulate the gas, an important safety feature that cuts the gas in the event of a fault. If the Thermocouples are nearing the end of their life, then they’ll keep switching off, stopping your Boiler in the process.

Old Thermostats

When we attend Boiler repairs, we sometimes find that the Boilers fine, and it’s the thermostat that has failed or isn’t working correctly.

Frozen Pipes

Modern Condensing Boilers use condensate pipes to take away wastewater.

These pipes must be adequately lagged. Otherwise, in winter, they can freeze, shutting down the Boiler. Defrosting and insulating of the pipe’s undertaken to get the Boiler back on and prevent the same issue from occurring in the future.

Whatever issues you’re experiencing with your Boiler, one of our experienced engineers will solve them for you.
