When Should I Buy a New Boiler?

Knowing when to replace your boiler should be your top priority because it accounts for more than half of your energy costs. Read out how frequently your boiler needs to be replaced by reading on.


Consider buying a new boiler because boiler breakdown can necessitate expensive repairs. Since boilers typically last between 10 and 15 years, replacing your old one with a new one can be more cost-effective if yours appears to be slowing down.

Heating and Hot Water

If their boiler is having trouble providing them with the warmth and hot water they require, many homeowners choose to replace it. A boiler with a high kW output can be best for you if you use hot water or heat a lot. You can rely on our Home Experts to assist you in making the best choice for your family.


Using More Energy Your energy expenses are more significant than installing a brand-new, A-rated heating system in your house if your boiler has a low energy efficiency rating. Boilers that use less energy can save heating costs and preserve the environment.

Move the System

Installing a new boiler might be more beneficial if you want to know where your old boiler is. Additionally, it can be less complicated because you'll have the choice to modify your system and obtain a central heating source that is more energy-efficient.

Which Kind of Boiler Should I Buy?


The combi boiler is the most advanced and widely used type of boiler in the UK. A combi is a single, efficient heating system that may be built without requiring extra tanks or cylinders.


Without using any tanks or cylinders, they provide rapid heating and hot water on demand as and when required. They are therefore ideal for households with 1-2 bathrooms.


Combi boilers have a variety of advantages, but there are also certain things to keep in mind. You will require intense water pressure at your property because combi boilers draw their water directly from the mains. If not, you will need to wait until it refills before using the hot water from you. This could occasionally result in a little delay in taking a bath. However, combi boilers won't have this issue.


There are numerous variables for the regular boiler. Open-vent, heat-only, and conventional are a few examples. They are the oldest type of boiler now in use and are frequently found in older homes constructed in the 1960s and 1970s.


Regular boilers heat water for cylinder storage, much like a system boiler. But a feed and expansion tank and a hot water cylinder are also required. Since they don't draw water directly from the source, this tank is installed in the loft and feeds cold water to the boiler.


They are only advised for homes where this type of boiler is already present because they are substantial heating systems requiring a large pipe network.


In the past, conventional boiler systems were the most popular boiler. Although the combi boiler has recently surpassed traditional boilers in popularity, there are still some situations when a conventional boiler is preferable.


A conventional boiler system needs a cold water tank and a hot water storage cylinder so that it can supply much hot water to many outlets throughout the house. A conventional boiler can be the solution you've been looking for if your home currently has low water pressure.

What Is the Best Boiler Size for My Home?

The size of a boiler is different from its actual size. Instead, we're talking about the output in kW, which is the unit used to measure how much energy the boiler emits as heat. Choosing the right size boiler for your home is essential because it will mean you are not wasting energy and money you don't need.



1-2 bedroom, 10 radiators, 1 bathroom


3-4 bedroom, 15 radiators, 1-2 bathroom


4+ bedroom, 20 radiators, 2+ bathroom

Can I Move My Boiler?

It's possible to move a boiler. However, as this typically facilitates a quick and straightforward installation, it can save you time and money to install your new boiler in the same area as your old one.


A combi boiler can be installed anywhere or moved a short distance. Moving a system or typical boiler, however, can be more constrained, and this is so because they also contain outer sections in addition to the boiler.


A hot water storage cylinder is required for both, which stores hot water for your faucets. An airing cupboard is frequently where this big cylinder is kept. In the loft, above the boiler, a feed and expansion tank is also necessary for a typical boiler.


Our professionals will assist you in determining whether moving your boiler is the best for you.

When to Replace Your Boiler

It may seem unusual to be concerned about a new boiler during the summer when it is warm outside, and you are not thinking about central heating. However, you don't want to switch on the heating in the winter, when you most need it, only to discover that it needs to be fixed, leaving you out in the cold.


A replacement can take 1-3 days, depending on the sort of boiler you're installing, but most like-for-like combi boiler swaps are typically finished in a single day.


On the other hand, even if your boiler is operating normally after 10 to 15 years of operation, it's time to think about replacing it. This is because newer, more environmentally friendly appliances are more efficient than older models.
