Boiler Maintenance Tips & Tricks

Boiler Maintenance Tips & Tricks

APH Services know that regular maintenance of your boiler will save their clients money. We Service Hertfordshire, Essex, Cambridgeshire, London and Home Counties with boilers repairs, maintenance, checks and installations. We will leave any boiler job with a label and reminder for when you should next have your boiler serviced or checked. It is important that if you notice anything unusual about your boiler performance, sounds or smell then you should immediately contact for assistance. A well maintained boiler will save you money in the long run from costly repairs BUT could also save your life. Remember, a faulty boiler can be fatal. Healthy boiler’s are more efficient, so cutting your energy bills.

Annual Service:

Your boiler should be serviced once a year by an engineer listed on the Gas Safe Register, even if it seems to be in working order. Your APH Services engineer will check all the parts and clean the components and leave you with a label reminder of your next annual service date. September is a good time to arrange the service, so you can be sure your boiler can take the strain of the winter months. 

Turn the heating on:

Boilers can seize up if they are not used regularly. Experts therefore recommend that you turn on the heating for ten or 15 minutes every so often during the summer months, just to keep the boiler ticking over. 


Boilers lose pressure over time, which can cause them to run inefficiently. Check the pressure gauge on your boiler. Contact an APH Services engineer if in doubt.
Bleeding the Radiators:
If your radiators are colder at the bottom than the top, air is trapped in the system. You therefore need to release the air by ‘bleeding’ the radiators. If you don’t, the system is not working efficiently, putting an extra strain on your boiler and effectively wasting you money. Contact an APH Services engineer if in doubt.

Warning signs:

Leaks, cracks, clunking noises or black, sooty marks all suggest you have a problem. So check your boiler regularly and look out for warning signs. The sooner you detect and repair a fault, the better. It’s also wise to make sure that any external vents, flues and airbricks are free from blockages and debris. 

Blue flame:

The flame in your boiler should be a strong, clear blue. If it appears yellow or smoky, there could be something wrong and you should call a APH Services immediately.

Clear clutter:

If your boiler is in a cupboard, is it surrounded by coats, shoes, bags and other clutter? Boilers need ventilation so the space around the appliance should be kept free from clutter. Your boiler should also be relatively easy to access, so make sure you keep the cupboard reasonably tidy. Ask your APH Services engineer to advise on whether your boiler has adequate ventilation.

Lag the Pipes:

When the temperature drops below zero, the boiler’s external condensate pipe can freeze. The boiler will then cut out as a safety precaution. You can melt the ice by pouring warm water over the pipe, but you can prevent the boiler from freezing by insulating the pipes or by keeping the heating on a constant low setting when it is very cold. Ask your APH Services Plumber for more information.

Gas safety:

A faulty boiler can produce carbon monoxide – a gas that you can’t see, smell or taste. Carbon monoxide can kill, which is why every home should have a carbon monoxide detector, preferably with an alarm. Put it near the boiler and check it every month to make sure it’s working. Ask your APH Engineer to check yours!
