How to choose a new boiler?
We'll help you understand what you need to know when choosing a new boiler for your home. Things like boiler types, efficiency ratings and the space you'll need.
What type of new boiler should I choose?
Understand the advantages and disadvantages of the three main types of boilers and find the one that's right for your home.
Combi boilers.
These are great if you live in a smaller home. They don’t need a separate hot water cylinder or cold water storage tank, so they could easily fit into a cupboard and don’t take up any of your valuable space under the stairs or in the loft (for example).
Regular boilers.
If you often use hot water around your home, then a regular - or “condensing” - boiler is probably best for you. They can take up more room than a combi as they often come with a cold water tank as a kind of back up but you’ll have a plentiful supply of water ready to be heated regardless of water pressure or any other issues.
System boilers.
Does your home have more than one bathroom? Then a system boiler is a good choice. They’re like a condensing boiler but with a large tank for storing extra hot water. Again, they take up more room than a combi boiler, but you have a constant supply throughout your home when you need it.
How much would I save with a new boiler?
See how much you could save by replacing your old boiler with a new A-rate condensing boiler.
How well is your boiler running?
We all know when a boiler is running well, mostly due to how warm the house is and we've not just stepped into a shower that could freeze us in seconds.
Are your radiators not getting hot enough? They could have air trapped in them. The best way to deal with it is to bleed the radiators. Find out more on how to bleed the radiators easily in this helpful guide.
Of course, boilers do sometimes need replacing. While boilers generally have a lifespan of around 10-15 years, there comes a time when they need to be replaced. It's important to recognise the signs that say your boiler may have problems, like:
Leaking water.
Making strange noises.
Pressure dropping.
The pressure is too high.
Overheating.
If your boiler is doing any of these things, we've put together a handy guide to show you your options and whether you need to replace your boiler with a new one.
Remember, a well-maintained boiler not only gives you a comfortable living environment but also helps with energy efficiency and cost savings in the long run. By addressing any signs of boiler problems quickly, you can avoid major disruptions and be sure your home will remain warm throughout the colder months.

When should I get my boiler replaced?
If your boiler has been playing up for a while or you’re just not getting the hot water you need when you need it, it’s probably time to get a new boiler in.
But it can be difficult to work out if you just need a repair or a new boiler. That’s why we’ve created a guide to help you make the right choice.
Pick the right size boiler for your home.
We've put together the info you need to know so you can pick a new boiler that’s not too big, not too small, but just the right size for your heating and hot water requirements.
