Boiler Replacement Services in Lambeth & South London

The price of purchasing and installing a new boiler will always reflect the fact that boilers are long-lasting, high-wearing appliances, and the price will always reflect that fact. The good news is that they may have a lifespan somewhere between 15 and 20 years if they are properly maintained and repaired on a consistent basis.

All good things must eventually come to an end, so clients who experience ongoing boiler issues or whose boiler isn’t operating effectively will realise it’s time to look for a new model.

Although annual servicing may extend the life of a boiler and reduce the strain it experiences, a boiler that is more than 15 years old will require more fuel to provide the same amount of heat. Energy costs and the risk of a non-safe boiler might rise if it isn’t replaced. If you want to know if you need a new boiler, check out these signs.

• Increasing costs

Do your bills keep increasing mysteriously? Your boiler’s age may be the cause. Simply put, you pay more to operate a boiler that is less efficient. While older G-rated boilers work at 70% or less efficiency, modern A-rated boilers function at above 90% efficiency.

• Constant breakdowns

We get it, the cost of a new boiler is significant. However, you know how inconvenient and costly it can be if your boiler fails on a frequent basis. With the family shivering and repair costs piling up, it may be time to consider whether or not investing in a new boiler might be financially beneficial.

Regular maintenance on your boiler is essential to ensuring that it continues to function properly, but if you find yourself calling for a Gas Safe expert more frequently than once a year, it may be time to shop around.

• Strange noises

There are several noises that your boiler and radiators generate, the majority of which are entirely unharmful. However, any changes to the noise’s nature or intensity should be noted.

If you hear tapping on your radiators or pipes, your central heating system may be accumulating sludge. It might sound terrifying, but a Powerflush can easily repair it.

Humming, vibrating, or pounding, on the other hand, might indicate a more serious problem with either the boiler or the central heating system, and you should change your boiler. To identify the source of the noises and resolve the problem, you’ll need the assistance of a heating engineer.

• Leaks or drips

The water shouldn’t ever leak out of your boiler. If it does, this is typically an indication that an internal component, such as a valve or seal, has been damaged and has to be replaced. If it is not addressed, it might result in a short circuit in the electrical system or even harm to the structure of your home.

Numerous spots on your boiler might start to leak. Knowing where your boiler is leaking from and if a leaking boiler is an emergency or not can help you identify the exact issue. A damaged part inside the boiler is the most frequent cause of a leaky boiler. There may be damage to the pressure valve or pump seal. Your boiler pressure can be too high if the pressure valve is to blame. If the problem is with the pump, it can simply be that it has worn out over time through repeated or heavy use.

The pipes in your system are another frequent location for leaks. It’s advisable to contact one of our experts who can accurately diagnose the issue as rust might be the cause of this.

If you discover a leak, turn off the boiler immediately and get it inspected by one of our trained specialists. It is hoped that it can be fixed, but if it can’t, it may indicate that your boiler has to be replaced.

• Low boiler pressure

The need for a new pressure valve, water leaks, or bleeding radiators are some of the potential causes of low pressure in a boiler. Other potential causes include a leaking pressure valve. It won’t take you long to figure out how to check the pressure in your boiler. You only need to check the pressure gauge that is already included into the device. If the needle is below 1, it’s possible that there is an issue that has to be addressed.

Get in touch with one of our engineers to see whether there is an underlying issue if you notice that pressure is dropping fast even after repressurising your system.

• Problems with the thermostat

If your thermostat starts turning on or off by itself without any interaction from you, or if it starts losing its accuracy, you might want to consider getting a new one. There is no reason to believe that this issue is related in any way to the boiler itself. Nevertheless, you might want to get it checked out just to be on the safe side!

• You see a yellow flame

The flame in your boiler should be a brilliant blue colour. If it has turned to a yellow or orange colour, your boiler has to be serviced right away by an Gas Safe registered engineer. They will be able to assess the gravity of the situation and advise you on the most effective method to address it.

• Odd smells

Boilers frequently develop an odour best compared to “rotten eggs,” which is an issue. Although this unpleasant odour is not an indication of danger nor a signal of the boiler or heater breaking down, it is strong and unpleasant, so when a boiler starts emitting it, you should address the problem as soon as possible.

Anaerobic bacteria, which often thrive in the magnesium and aluminium parts of both pieces of equipment, are the source of the sulfur/rotten egg stench that afflicts many boilers. Periodically, these components—known as sacrificial anodes—need to be changed. In addition to being frequently confined in a basement, many boilers create a warm, dark, and moisture-prone environment that is extremely alluring to bacteria, particularly the smelly anaerobic bacteria that causes the sulphur smell.

Having to replace your boiler is typically a very expensive endeavour. It’s possible that you’re curious about whether or not you should also consider changing out your radiators at the same time. If the age of your current radiators is greater than 15 years, it could be a good idea to speak with your installer about the possibility of changing them.

If the water that is being circulated around your central heating system is flowing via a current radiator rather than older radiators that have been corroded, then this will be much better for your new boiler. Your brand-new boiler’s efficiency may suffer as a result of this. A comprehensive cleaning, often known as a powerflush will be performed on your heating system before the installation of your boiler. Despite the cleaning procedure, older radiators will discover that rust may build up again more quickly, which may result in chilly patches within the radiators. Because of this, the output of heat may be reduced.

The increased surface area of new convector radiators often results in a 50% boost in efficiency. The radiator can heat up considerably more quickly and create more heat while using less energy thanks to metal fins on the rear of the radiator panel, which enhance the surface area. As a result, your boiler will shut down more quickly, saving you money on fuel costs. Modern radiators also use less water to circulate heat, which means your boiler won’t have to work as hard.

If the ages of your radiators vary, don’t worry. Instead of replacing all of the radiators, you might simply alter some of them. We can offer guidance if you believe that some of your present radiators don’t provide adequate heat.

Repairing your boiler is often the simplest, least expensive, and fastest option to get your heating system back up and operating. Newer boilers are more likely to be reliable, so it may be some time before you need to replace yours. However, a new boiler should be considered if your current one is outdated, no longer under warranty, or poses safety risks.

Always seek the counsel of a qualified engineer who can help you balance your alternatives and choose the best course of action.
