The average life expectancy of a boiler is about 10-15 years, so if your boiler is around this age range it may need replacing, especially if your heating system has needed to be repaired frequently.
At High Wycombe Plumbing we’re experts at replacing boilers and can provide you with a bespoke boiler replacement service for any of the major boiler brands.
Replace Your Boiler
Oftentimes, bigger problems come from the small problems that went unnoticed and ignored. So, here are the early warning signs to give you a cue on when to consider replacing your boiler:
Water leaks show you that the flow of water is not working properly. These can be caused by corrosion. Metal piping usually experiences this problem over time and most old boilers are prone to it.
Less pressure often signals that it goes somewhere that it shouldn’t have. There are two reasons this occurs in boilers, which is either water leaks or gas coming out of the joints or valves.
The pilot light is where the heating starts and you might keep asking why it often goes out for no apparent reason. Usually, it’s due to the blockage in the gas valve or some stuff were stocked on the orifice or holes where the gas comes out. In order to fix this, you will need to open the access panel and it will be annoying to fix if it happens frequently and also poses a bigger problem that might cost your safety.
You might have thinking about strange noises at night which keeps you awake only to find out that it’s coming from your boiler.
The banging or clunking sound in your boiler is called ‘kettling’ and this means that your heat exchanger is blocked by minerals from hard water called lime-scale that has built up over the years. The blockage in the heat exchanger causes the pressure to go up thus making these noises and can break your boiler. For old boilers, too much pressure accumulated can cause an explosion. A boiler might not look dangerous but it can certainly be one if left unsupervised.
The whistling sound in your boiler is caused by trapped air which is also caused by some blockage in the airways. A simple way to fix this is to let the trapped air out.
The gurgling sound is often heard from your pipes and is caused by air bubbles. These air bubbles disrupt the flow of water which affects the pressure and consequently, the amount of heat produced. This also creates a domino effect of frozen pipes. You can unfreeze these pipes if you know how to do it but it’s recommended to contact a professional to safely fix it.
Condensation is the process by which gases in your boiler are transformed to heat. It is suggested to install these pipes inside the house to keep it from freezing during winter. However, this might not be the case for everyone so, if the condensate pipes are outside and not insulated, they may freeze in extreme weather conditions. This is the perfect time for insulators to become handy. It is suggested to cover these pipes with insulation like heating pads to prevent freezing if installed outside the house. If this goes unmanaged the problem will spread out to the entire heating system.
This is probably a sign of an aged boiler and it is likely time to start thinking about replacing it. This behaviour is probably due to the final gulp of air of your boiler that’s caused by accumulated problems within its system. Some of the main causes are due to having multiple blockages in the orifice, blocked pipes or heat exchanger which are all byproduct of old equipment.

A reduced amount of pipework repairs or risk of pipe-freezing.
Cheaper heating as it’s also compatible with solar heating systems.
The temperature can be adjusted through the latest smartphone. heating apps such as Tado Smart Thermostat, Nest and Honeywell Evohome etc.
Not advisable for:
Big households with multiple baths.
Homes that were installed with conventional boilers.
Homes with low water pressure.
If you need to run the baths and taps simultaneously.
This type of boiler is more of a space-saver version of the conventional boiler as some of the components are built-in.
Best for: Larger households with multiple baths.
Installation is easier as it has fewer components detached from it.
Faster transfer of heat from the boiler to radiators.
Access to hot water for multiple running baths at the same time.

As for households with existing pipework from old regular boilers, there’ll be quicker installation as the structure has already been set and in most cases, only a few minimal adjustments need to be made.
The water pressure doesn’t affect boiler performance.
Not advisable for:
Small households due to big components such as tanks that will require some space.

This type of boiler uses oil which comes in the form of liquid and converts it to heat that’s supplied to your radiators, taps, and baths.
Best for: Best suitable for areas that have no access to mains gas grid and electricity supplies.
Modern oil condensing boilers are more efficient as they recycle some heat energy that would normally be wasted.
It can come in a combi form.
Hard to find an authorized person to maintain the unit as gas engineers are easier to find than oil engineers.
Maintenance is mandatory for oil boilers.
