Boiler Maintenance Tips

Although it is often overlooked by homeowners, boiler maintenance is important to ensure safety and to keep running costs down. But where do you start?

Keep reading and give our Easy Boiler Maintenance Tips a try!

1.Get Your Boiler Serviced Annually 

A professional service every year will keep your boiler working at its best and subsequently prevent breakdowns, keep heating bills low and even maximise the boiler’s lifespan. Services need to be carried out by a Gas Safe engineer who can check each element is in safe working order as well as identify any minor issues before they turn into inconvenient and more costly breakdowns. If you think your boiler is due for a service, get in touch with a member of our team.

2.Check The Boiler System Pressure

Your boiler must be set at the right pressure to be able to circulate hot water around the radiators and pipes. You can check your boiler pressure by checking the pressure gauge to ensure it is working at the level suggested by the manufacturer’s user instructions (this is typically between 1 and 2 bar). If the pressure is incorrect, you can adjust this yourself.

3.Bleed The Radiators Every Year

Over time, air can become trapped in your radiators; these pockets of air will prevent the radiator from heating up fully, which often creates cold patches at the top of the radiator. Bleeding your radiators should release this air, however, you will need to top the pressure up on the boiler once you have done this. The radiator can be bled via the air bleeder at the top. Be warned: if somebody has painted over the air bleeder, they may be harder to adjust – but it’s nothing some force and a bit of WD40 shouldn’t solve. If it still won’t budge, give a heating engineer a call.

4.Ensure Your Radiators Are Balanced

Are the radiators furthest from the boiler not as hot as the others? Balancing your radiators should help your system to heat your home more evenly. This isn’t as straightforward as bleeding your radiators so you may wish to call a professional heating engineer to ensure a safe and accurate result.

5.Be Aware of Potential Radiator Problems

You might find that your radiators feel hot at the top but much cooler at the bottom. This is quite a common heating problem and is caused by magnetic sludge accumulated at the bottom of the radiators. Having a sludge build-up will often result in higher energy bills, and damage your boiler and controls over time, so it’s definitely something to keep an eye on. The best way to remove sludge is with a flush. If you think you may need a flush, have a look at our Adey MagnaCleanse Flushes here which are both more cost-effective and less disruptive than traditional power flushing methods. We also include a Magnetic Filter with every MagnaCleanse Flush which will save you money on your fuel bills and reduce expensive maintenance costs for the lifespan of your boiler.

6.Make Sure Your Boiler Flame Is Blue

If your boiler is a condensing type the following would not be applicable, this only applies to very old boilers as with new modern boilers and burners, older boiler parts are not available. Your boiler should always burn with a strong blue flame. If the flame in your boiler is yellow or orange, there could be a risk of carbon monoxide – in this case, call a Gas Safe registered engineer immediately. You should have a carbon monoxide alarm, but if you spot that your boiler flame is no longer blue and the alarm hasn’t rung call an engineer straight away to be sure.

7.Allow Your Boiler to Be Well Ventilated

Boilers need space to be well ventilated so try to avoid covering or surrounding your boiler with clutter. If your boiler is in a cupboard, don’t worry a gap of 700 mm between the wall and boiler will suffice.  Ensure you never allow clothing or linen to be in direct contact with boiler or the boiler flue.

8.Keep An Eye Out For Any Dripping From The External Pipe

If you notice your system pressure dropping, one of the first places to check is the PRV  (Pressure Release) pipe may be dripping. Anything from a slow drip to a fast drip will need attention from a Gas Safe engineer. Common causes are PRV passing, expansion vessel holding incorrect system change. This can easily be rectified during an annual boiler service via a registered Gas safe installer/engineer.

9.Put Lagging On Your External Pipes

Experienced issues with freezing pipes before? Minimise the likelihood of a boiler breakdown this winter with some lagging. Before temperatures drop, you can pick up some exterior lagging called Type O lagging. This lagging is waterproof and has some resistance to the sun’s UV rays, this lagging will lessen the chance of them freezing in the colder months. You must ensure the joints are taped together and there are no gaps on external pipework. You also need to ensure that the external pipework terminates into an external drain. All external condensate pipework has a natural fall. Check out these tips to help you get started.

10.Never Attempt To Repair Your Boiler Yourself

The only people legally allowed to repair your boiler are Gas Safe registered heating engineers. It’s incredibly dangerous to work on boilers if you aren’t properly qualified and can even lead to carbon monoxide poisoning, explosions, fires, and more. Minimise the risk and call an expert.
