Why should I have my boiler services?

Safety and to check for carbon monoxide. Regular servicing will also increase efficiency, reduce emissions and ensure safe operation of your boiler.

My boiler has gone to lockout, do I need an Engineer?

Have you checked the level of oil in your tank? Have you tried pressing your lockout reset button (you can do this a couple of times)? If you have plenty of oil left in your oil tank and the reset button has failed to fire the boiler, then you do need to call an Engineer.

The radiator is cold at the top and warm at the bottom, why?

This is usually due to air trapped at the top of the radiator. This can be released through the bleed point at the top of the radiator, using a suitable radiator airing key.

Boiler is hot but the radiators are cold, why?

This would indicate the circulation pump or a motorised valve could have failed. Heating remains on when clock/programmer is off? Should the boiler remain on when there is no demand through the programme a faulty actuator on a motorised valve is the most common cause.

How long does a service take to complete?

Normally, without any complications it will take:-

1 hour for a non-condensing boiler and

1 1/2 for a condensing boiler 

these times are for a full service

Where is the oil shut off valve located?

The main oil shut off valve will normally be located on the burner unit of the boiler. In most cases the front door cover will need to be removed to gain access. The burner unit will have a control box with a reset button (normally illuminated if the unit has tripped). Push the reset button to initiate a start up, always refer to the manufacturers instructions on how many times the button can be reset (normally a maximum of three attempts).

No pressure on gauge on boiler, why?

The majority of today's boilers are installed as sealed systems, where there is no header tank to automatically top up the system with water. A pressure gauge will be found on the front of the boiler or on a nearby pressure vessel. A filling loop will be incorporated with two valves to regenerate the system pressure with water. The system

pressure will normally indicate 1 Bar when the system is cold. A gauge showing no pressure would indicate the system requires to be topped up.Why not ask the service engineer to demonstrate the procedure at his next visit.

Which parts are normally replaced at a service visit and are they included?

It is recommended that nozzles, filters and flexible oil lines are replaced at service visits. All parts fitted are charged in addition to the service labour charges.
