SIGNS THAT YOUR 
CENTRAL 
HEATING NEEDS 
SERVICING
OVERVIEW 
• Whilst we’re not heavily reliant on our central heating systems 
in the summer, they become increasingly important to both 
individuals and businesses as temperatures begin to plummet. 
There’s nothing better than coming back to a warm and toasty 
home after a chilly commute and when it comes to work, there 
are regulations in place regarding optimum temperatures.
• So, to ensure you have a system that functions optimally all 
year round, we’ve made a list of signs that it may be time to 
enlist the help of central heating experts.
• Boiler on the blink : Whilst it may seem obvious that a faulty 
boiler requires professional attention, it can sometimes be 
difficult to know when your boiler is on the blink. If it breaks 
down altogether it will undoubtedly need repairing or replacing. 
• Popping or banging sounds: If you hear popping or banging 
sounds coming from your boiler, this is likely a sign of kettling. 
When your boiler experiences a build-up of limescale and 
debris, this restricts the flow of water through the heat 
exchanger, causing the water in the heat exchanger to boil and 
evaporate into steam.
• Spike in energy bills: A spike in energy bills is often a telltale sign that 
your boiler is operating inefficiently, and with this in mind, it may be time 
for a replacement. Whilst it could simply be that a dip in temperature is 
causing you to become more reliant on your boiler, it may be worth 
monitoring your usage for a few months and if something doesn’t quite add 
up, it’s time to call in the professionals. A central heating engineer will be 
able to analyse your boiler’s efficiency and if it’s not functioning optimally, 
they may advise that a replacement is the most cost-effective option.
• Water leak: If you notice that your boiler is leaking water, no matter 
how big or small the leak is, you should always contact a professional. 
This is likely a sign that an internal component has broken and if left to 
exacerbate, this could lead to an electrical short-circuit and a significant 
leak could also cause structural damage to your property.
• Outdated system? Opt for boiler replacement services: As a 
general rule, if your boiler is more than a decade old, it may be time to 
start shopping for its replacement. After all, while these systems are 
designed with longevity in mind, they can’t last forever, and a boiler 
that’s 10+ years old is unlikely to be functioning at optimum efficiency. 
UPDATING YOUR CENTRAL HEATING SYSTEM 
WITH NEW FEATURES 
• Whilst a boiler replacement is sometimes the best option, there 
are ways to modernise a central heating system. With the 
prices of energy rising on a fairly regular basis, many home and 
business owners are looking for ways to reduce their energy 
usage, and the implementation of heating controls is the 
perfect way to do this. Installations such as thermostats and 
timers give you the power to control the temperature of your 
home, as well as schedule when you want your heating and hot 
water to turn on and off. You may even be able to control your 
boiler via your smartphone or tablet by utilising smart heating 
controls.
