Boiler Servicing: What is a boiler service?

If you’ve ever heard anything about a Boiler Service, it’s likely to be from someone that’s had a broken boiler and had to call out an engineer unexpectedly to fix things.

The hassle of a broken boiler, finding a trusted engineer and the cost alone is enough to get anyone to recommend having an annual boiler service to make sure your boiler remains in tip top working condition.

But what does a boiler service actually do?  

A boiler service typically means a Gas Safe engineer will visit your home and run a series of checks on your boiler, making sure it’s functioning safely and effectively. A boiler service will usually include the following key areas & checks:

1. Boiler Control Checking (Thermostats etc)

A thermostat is basically the control you use to help regulate temperature in a heating system. It allows you to set your desired temperature for your home and works to keep your rooms at your desired heating level. If your home gets colder, your thermostat can switch the heating on to warm it up. If this breaks it’s like losing your TV remote control.  You might still be able to do something with the boiler, but it’ll be a lot harder and you won’t be able to do everything you’re used to through your thermostat.

2. Gas and pressure flow tests

When heating is turned on, your boiler pressure is recommended to be between 1.5 and 2 bar. Most boilers highlight this on a pressure gauge which helps you see if the needle is pointing to the correct numbered amount of pressure.  If it’s not, it can have a negative effect on the efficiency and effectiveness of your heating system, making it hard to keep your house warm and even costing you more on your energy bills.

3. Inspection of the inside of the boiler

As well as a visual inspection of your boiler, engineers will also take the casing off your boiler to check the components and ensure everything is in working order.  They’ll also clean the inside of the boiler if there’s been any build-up of dirt. Checks like these typically include things like the heat exchanger, burner, main injector and spark probe.

4. Flue checks

The flue acts as the boiler’s chimney, but it’s not smoke and soot being channelled away from the inside of the home, it’s carbon dioxide and water vapour that’s emitted.

For the Flue check, the engineer will ensure there are no obstructions, that it’s working properly and safely fitted.

5. Inspection of water and gas pipework

A full boiler service can include checking the entire system, including your pipework.

Leaking, blocked or damaged pipes have negative effects on the performance of your heating and hot water system. This inspection includes both a visual inspection of all accessible gas pipework as well as testing to ensure there are no leaks.

6. Checks on all electrical connections

This allows the engineer to check for any working faults.
