There is something satisfying about returning to a boiler you installed 20 years ago and finding it still doing the job it was designed to do.
This Radiant boiler was installed by The GHS Group around two decades ago, and we have continued to look after and service it ever since. Radiant boilers are now rarely seen in the UK, and support and parts availability for older models can be increasingly limited.
That does not automatically mean the boiler needs to be ripped out and replaced.
An unsupported boiler isn’t necessarily a failed boiler
As boilers get older and manufacturers withdraw models from the market, maintaining them can become more challenging. Some engineers and heating companies understandably choose not to work on older or unfamiliar appliances, particularly when manufacturer technical support or replacement parts are difficult to obtain.
In those circumstances, a homeowner may quickly find themselves being offered a quotation for a new boiler.
Sometimes, replacement is absolutely the sensible option. But age alone shouldn’t necessarily condemn a boiler.
If an older appliance is safe, operating correctly, and can still be maintained responsibly, there may be no immediate reason to replace it simply because the badge on the front is no longer familiar.
Twenty years of knowing the same boiler
One of the advantages in this particular case is continuity.
We installed this Radiant boiler around 20 years ago and have maintained it throughout its working life. That means we haven’t simply walked into a property and been presented with an unfamiliar old appliance with no history.
Regular servicing gives an engineer an opportunity to monitor how a boiler is ageing and identify changes before they become major problems.
Over the years, this can build up a valuable picture of the appliance’s condition.
Regular boiler servicing is about more than preventing breakdowns
A proper boiler service isn’t simply about making sure the boiler fires up.
Depending on the appliance and manufacturer’s requirements, an engineer may inspect and test various aspects of its operation, including combustion, flue performance, safety devices and the general condition of components.
On an older boiler, this becomes particularly important.
Regular servicing can help identify:
- deterioration before it causes a breakdown;
- signs of combustion or flue problems;
- water leaks and corrosion;
- components beginning to wear;
- changes in boiler performance;
- situations where continuing to repair the appliance is no longer economical or sensible.
Gas appliances should always be inspected and worked on by a suitably qualified Gas Safe registered engineer.
Repair or replace? It shouldn’t automatically be one answer
We are certainly not suggesting every 20-year-old boiler should be kept running indefinitely.
There comes a point where replacement can be the better option. Parts may become unobtainable, several expensive components may begin to fail, efficiency may be poor compared with modern equipment, or the appliance’s condition may make further investment difficult to justify.
The important point is that the decision should ideally be based on the boiler’s actual condition, rather than simply on its age or the fact that the manufacturer no longer actively supports that model.
For this Radiant boiler, regular maintenance has helped give it a remarkably long working life.
There is value in having someone who knows your heating system
This is also one of the advantages of developing a long-term relationship with a local heating company.
At The GHS Group, we look after heating systems across Hampshire and the surrounding area, including systems we installed many years ago.
Where it is safe, practical, and economically sensible to maintain an existing appliance, we will assess the options. Where replacement genuinely makes more sense, we can explain why and discuss suitable alternatives.
Our aim isn’t simply to replace something because it is old. It is to give homeowners practical information so they can make an informed decision about their heating system.
Does an old boiler need replacing just because parts are becoming difficult to find?
Not necessarily. It depends on the boiler’s condition, the availability of the required parts, safety, reliability, and the cost of ongoing repairs. An engineer needs to assess the individual appliance.
Is a 20-year-old boiler less efficient than a modern boiler?
Older boilers can be less efficient than modern condensing appliances, particularly compared with a correctly designed and controlled modern heating system. However, efficiency is only one factor when deciding whether immediate replacement makes financial sense.
Should I have an older boiler serviced every year?
Annual servicing is generally sensible for a gas boiler and becomes especially valuable as the appliance ages. It allows its condition and operation to be checked regularly rather than waiting until it stops working.
Looking after your boiler for the long term
This Radiant boiler is a good example of something we see regularly in heating: good installation and continued maintenance matter.
Twenty years after we originally installed it, we’re still looking after it.
If you have an ageing boiler and would like sensible advice on whether it can continue to be maintained or whether it’s time to consider replacement, speak to The GHS Group.
