Other Issues that Can Effect Your Boiler

You may encounter your boiler not operating and not displaying a fault code. In this case, it’s worth checking your water, gas, and electricity supplies to ensure there is no issue with supply. If you have a prepay meter, make sure you have credit available. Also, check your property has running water from the cold taps, that your gas is working by lighting the hob or gas fire and that your electricity is working by turning on a light within your home.
Your boiler may be on a separate electrical circuit if the rest of your home has electricity, but the boiler LCD isn’t displaying anything. So then, it can be that your boiler may not receive power, and you may need to call an electrician or Gas Safe engineer.

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


A sure sign that your boiler is due to be replaced is the kettling, gurgling and banging sounds that you might be hearing from your boiler when you run the hot water tap or turn on the central heating

Strange smells

While carbon monoxide does tend to be odourless, some gas companies do add a scent to help it become easier for you to detect if a leak has occurred. An eggy, sulphur-like smell around your boiler is a sure sign that there is a carbon monoxide leak and you should open all the windows and get out of the house as quickly as possible. Contact the Gas Emergency Services as soon as you can.

Yellow flame

A healthy boiler that’s working well should burn with a blue flame. However, if you’ve noticed a yellow flame on your boiler, this could be a sign of a serious issue such as a carbon monoxide problem. This gas is colourless and odourless and often, a yellow flame is the first sign that there’s a problem so it’s important to keep your eye out for it. If exposure levels are high enough, carbon monoxide can lead to serious illness or even be fatal.

Increase in energy bills

A boiler that is getting old and is increasingly less and less efficient can cost more money than most people can afford to spare. And, upgrading to a boiler that includes modern smart controls will not only improve efficiency but also give you a greater control over your energy usage and spending.

Frequent breakdown

Are you noticing that your boiler is breaking down regularly or you are topping up your water pressure every week?

Reduced efficiency

When it comes to energy efficiency, some boilers are just missing the mark due to age. A boiler that’s rated ‘A’ in terms of efficiency will have an energy efficiency level of at least 90%. On the other hand, a boiler that’s rated ‘G’ will have an efficiency level of around 70%, meaning that for every £1 you spend on your energy bill, you’re losing 30p in wasted energy.

Expensive & difficult to find parts

If you’re having increasing problems with your boiler and you have been told by your boiler engineer that new parts are hard to find, it’s a clear sign that your boiler will probably need to be replaced soon. The older a boiler gets, the less likely it is that parts will be readily available. And if you’re struggling to find an engineer who is experienced with the type of boiler that you have, that’s even more reason to consider replacing it.
