Home Energy/Environment Should You Replace Your Radiators Along with Your Boiler?

Should You Replace Your Radiators Along with Your Boiler?


If your home’s boiler and central heating system are getting old, you might have considered replacing it. Replacing your boiler is usually essential after around ten years since boilers do not tend to last very long after this amount of time, and will typically start to experience more problems, not to mention become less and less energy-efficient. You know that the new boiler cost is likely to be less than the cost of dealing with boiler problems and mounting energy bills over time. But while you’re upgrading your boiler, should you also consider overhauling the entire central heating system and replacing your radiators? In some cases, a boiler replacement alone may suffice, but if your home has a very old heating system, replacing it all might be a wise idea.

If you’re looking into boiler replacement cost and have decided to buy a new boiler to upgrade your heating system, it makes sense to think about replacing your radiators at the same time. This would mean less disruption in your home and often costs less to do it all at once compared to having the two replaced separately. There are many benefits of replacing your radiators at the same time as your boiler, which include:

Increased Efficiency

Most people may think that all radiators are pretty much the same, but that’s far from the truth these days. Modern radiators have improved quite a lot in recent years thanks to an improvement in quality and stricter performance regulations. In fact, new radiators can be up to 50% more energy-efficient than those from one to two decades ago, and along with a new boiler, upgrading your radiators can be a sure way to significantly improve the energy-efficiency of your home, reduce the amount of energy that you waste and make massive cuts to your energy bills, meaning that your new boiler and radiators will eventually pay for themselves.

You can find out more about the cost of a new boiler and central heating system at Boiler Central, a central heating unit comparison site. Consider your budget for both a boiler and radiators and then use this site to find a boiler option that is an ideal choice for you. The combi boiler cost can vary, so it’s worth shopping around to make sure that you’re getting the best deal on the entire upgrade. Don’t forget to factor in the radiator and boiler installation cost when planning.


Over time, the radiators and metal pipes in your heating system can get rusty as the rust is collected by the water running through your system and returned to the boiler where it can build up. This collection of debris is known as sludge, and it’s a very good reason to consider having your old radiators replaced. In old radiators, the build-up of sludge can quickly prevent them from heating at their full capacity. You may be able to have an engineer power flush your radiators to remove the sludge build-up, but this can be a very costly job without a guaranteed result. And since old radiators are more likely to be corroded, the sludge formation will only begin to build up straight away after the power flush treatment.

Modernise Your Home

The days of radiators being purely functional are well over. Today, modern radiators are not only an essential part of your heating system but they can also be a key decor point in your home. Modern radiators are no longer designed to be practical but come in a wide range of styles, sizes and colours so that you can incorporate them into your home’s decor and make sure that they look good as well as doing their job. If you’re planning to upgrade your boiler, updating your radiators at the same time means that not only will you be able to increase the efficiency in your home, but improve its aesthetic with a designer radiator.

Modern Controls

Upgrading your radiators along with your boiler gives you the chance to add more modern controls to your home and improve the overall energy efficiency. If you want to make your radiators as energy efficient as possible, it’s worth upgrading to models that have thermostatic radiator valves that allow you to control the temperature of each individual radiator in your home. Super modern smart options can be hooked up to smart controls like Hive, allowing you to adjust the temperature or switch single radiators on and off in your home from a smartphone app even if you’re not physically present in the property. They can also monitor your activity in each room and automatically adjust the temperature to ensure that you are not using less energy than you need to.

Reduce Leaks

If you have older radiators in your home, it’s worth considering that installing a newer, more modern and more powerful boiler can often lead to an increase in the risk of leaks in older radiators. This is because of the pressure increase that occurs when the water is pumped around your central heating system at a more powerful rate. While those with some DIY knowledge can usually fix radiator leaks quite easily, it can be a hassle that you don’t need when you replace your boiler, especially if your radiators are very old and are at more risk of it happening regularly.

Save Money

The fact is that if you have old radiators, you are probably going to have to replace them at some point. Having your radiators replaced at the same time as your boiler might seem like adding on more expenses to an already costly job; however, over time it will save you money. Not only do many engineers offer discounts to those having new boiler and radiator installations at the same time, but it’s also much easier for an engineer to fit both when your system is already drained down.

If you’re considering getting a new boiler, it’s definitely worth thinking about the benefits of having your old radiators replaced at the same time.
