One of the most important things on your property is your boiler. It not only ensures you have hot running water, but it also heats your property which is essential during the autumn and winter months. It’s so important that you have the best boiler in working condition for the safety of your home and family. The quality of your boiler can affect not only how much energy you are using, but the cost of your heating bills too. You do not want to be running a boiler that is not working effectively and ultimately costing you too much.

A lot of people think about installing a new boiler on their property. While it is an expensive cost, a new boiler can often cut down your energy usage and ultimately your bills. Additionally, it can ensure you feel safe in your property with it working correctly. But if your current boiler is still working, how do you know when the right time is to replace the boiler? Here is our guide to when you should install a new boiler.

Important factors to consider

It’s not just as simple as just replacing your boiler when something goes wrong. After all, there are many reasons why you should consider installing a new boiler. Therefore, here are a few of the factors to consider that means it’s time to bite the bullet and call your local boiler engineer.

The age of the boiler

One reason why you might decide to replace your boiler is that you have had it for a long time. While the average boiler lasts around 10 to 15 years, the time can differ due to several factors. As the boiler ages, it’s worth considering buying a new boiler as it will not be running as effectively. Therefore, it will use a lot more energy to run to full capacity and you will receive higher bills. With the parts also not running properly, you are likely to be running into trouble more often. It might end up breaking down when you least expect it. 

A newer boiler will ensure you have the latest, high-tech boiler crafted to be highly efficient. You will be able to run it just as often but at a lot cheaper rate and with less energy used. You can also feel rest assured you have a safe, new boiler that is working safely in your home. And if you do sell your home in years to come, a new boiler is a good selling point.

The time of year

You need to be considering installing a new boiler in the summer. When you are in the spring and summer, you are unlikely to be using the boiler to heat your home. Therefore, you are less reliant on central heating, so it’s much easier for the family to have a new boiler installed at this time. That way, you are ready for the winter months and do not have to worry about having a boiler replacement when the heating is needed in your home.

Additionally, the boiler company is a lot less busy in the summer, so you can ensure a new boiler is installed at a time and date convenient to you. Also, having a new boiler during the summer will ensure you can have an impact when it comes to winter when the bills are higher. A new boiler will ensure your bills are cheaper during this expensive period.

Another sign you should replace the boiler is if there is significant corrosion. If this is occurring, which is common when you have had a boiler for a long time, it could lead to further problems which may result in the boiler breaking down. For instance, you could be at risk of leaks which could be damaging to your home as well as affect your family. It’s likely corrosion will be picked up during an annual boiler service, so this is important to do every year. If corrosion is occurring, this will only get worse over time and it is worth installing a new boiler in this case.

The efficiency rating 

You need to check what rating your boiler has. All boilers have an efficiency rating which gives you an insight into how much energy your boiler is currently using. This will impact your energy use and your total energy bill. If your boiler has a rating lower than a C or D, you should look at replacing the boiler. A low-efficiency rated boiler will cost you a lot more when you need to use hot water in your home. And while it’s a significant cost to replace your boiler, it will ultimately mean you will have a more efficient boiler if you go for a model that will also use less energy too.

Boiler leaks

Another reason you might want to look at installing a new boiler is if you are having leaks. These leaks are not safe for your home or your family. Leaks can occur due to many problems from your boiler. From a problem with the temperature valve to corrosion, these can all cause leaks. If these are occurring often, it might be time to replace the boiler. You don’t want to keep paying for recurring issues with your boiler. In the long run, it can be cheaper to just have the boiler replaced instead of dealing with problems.
