Why does my boiler need to be replaced?

There are many different reasons for upgrading to a new boiler. Whilst our engineers at Gas Service Ltd, will always try to repair your existing boiler, there comes a time where any boiler becomes beyond economical repair.
When and if this happens, our home surveyor will explain all the benefits of a new boiler installation. We never hard sell or use any technical jargon, just straight and honest advice so you can make the right decision.
If your current boiler was installed before April 2005, it is probably a non condensing boiler. It is now mandatory, when replacing a gas boiler in the UK to install a high efficiency condensing boiler. As well as being better for the environment, upgrading to a condensing boiler could save you money on your gas bill. Condensing boilers are highly efficient boilers, typically greater than 90%. They do this by condensing water vapour in the exhaust gases and so recovering its latent heat which would otherwise have been wasted.

Here are some of the signs that you boiler needs replacing:

Depending on the condition of your boiler and whether it’s been serviced annually, boilers can last up to 15 years.
Although, there can be signs that your boiler may need replacing, some of these have been highlighted below:

Radiators take longer than usual to heat up

This could mean your boiler is wearing out. Normally, a boiler can reach the maximum temperature very quickly.

Yellow flame

When a boiler is burning, the blue flame is a healthy sign. However, if the flame is yellow, this could be a problem. Yellow flame might be a sign that the boiler is leaking carbon monoxide.

Unusual smell

A healthy boiler never gives off any odour. If your boiler has started emitting a bad smell lately, it needs to be investigated. Usually, a faint smell means its leaking carbon monoxide.

Rising energy bills

Rising energy bills could be a sign of an inefficient boiler. When the heating system is old, it loses its efficiency. It tends to stop more in the middle of the operation.

Boiler keeps shutting off

When a boiler is in the habit of switching off, it is trying to tell you something. This could be happening because of low pressure, a faulty thermostat or pump issue.

Frequent breakdowns

When a boiler is losing its pressure, this might be because of a leakage in the system. The pressure also drops when air is escaping through a valve.

Reduced efficiency

If there is always something wrong with the boiler and you have to be without hot water and heating every other day, the boiler needs to go.

Replacements parts have discontinued

The parts of old boilers are usually hard to find. In some cases, they have discontinued. This means if any part breaks down, the boiler will become useless.

The boiler is making noises

When a boiler is turned on, it makes a noise. It’s normally a constant hum that you might not even notice. However, if your boiler is clunking, banging or whirring, these sounds should alarm you.

Kettling

Kettling is also a form of noise. When the water flow is restricted because of scale deposits built-up in the heat exchanger, it becomes hot and starts steaming. This causes a kittling noise. It happens when sludge is gathered around the heat exchanger.

Boiler Types Explained

Combi boiler

A combination or ‘combi’ boiler is both a high efficiency water heater and a central heating boiler in a single compact unit. Combi boilers heat water directly from the mains when you turn on a tap, so you won’t need a hot water storage cylinder or a cold water storage tank in the roof space.

They are also very cost-effective and energy-efficient as water is heated instantly rather than being heated and then stored in a cylinder. An added benefit is that hot water is delivered at mains pressure, which means that you could get a powerful shower without the need for a separate pump.

System boiler

System boilers require a cylinder for storing hot water, however the major heating and hot water system components are built into the boiler itself, making it quicker and easier to install. In addition, there is no need for a tank in the loft, so it can be an option in a home with little or no loft space or where the space is earmarked for a conversion.

These boilers are also compatible with solar water heating systems, which deliver environmental benefits as well as lower energy bills.

Regular boiler

Regular boilers (sometimes known as traditional, conventional or heat only boilers) are ideally suited to homes that already have a traditional heating and hot water system which is linked to a separate hot water cylinder. These boilers also need a cold water storage tank in the loft to feed the hot water cylinder as well as a tank that maintains the water level of the central heating system.

A regular boiler may be the best option for replacing an existing boiler if the property has an older radiator system, as it might not be able to cope with the higher water pressure that is delivered by system or combi boilers
