When you buy a new house or car, chances are you’ll do plenty of research. As the source of power for your heating and hot water, a boiler is pretty important, but would you do the same amount of research if you needed a new one?

A boiler replacement is an investment in your home and can take several days to fit, so it’s important you pick the right one. Here’s five things to consider when choosing your next boiler:

  1. Efficiency

Boiler efficiency is more important than ever before. An efficient boiler will not only reduce your emissions, it can lower your heating bills too. When it comes to shopping around for a new boiler, there are two types of efficiency ratings to look out for: ErP and SEDBUK.

ErP is rated from G (lowest) to A+++ (highest), while SEDBUK is rated from G (lowest) to A (highest). Both tell you how efficient a product is for heating your home. We recommend choosing a boiler with high efficiency ratings, like our HE range, to help you and the environment.

  1. Size matters

Boilers come in lots of different sizes. Some larger ones are designed to heat bigger homes, whilst others are built to fit into compact spaces.

How big your boiler needs to be is determined by a calculation, which looks at your house size, how it is built, insulation and how much hot water you’ll use. A qualified heating engineer will be able to calculate this for you and make recommendations.

  1. Easy to use

You’re the one who’s going to have to use your boiler, so make sure it’s one you understand! Ensure it has a simple, clearly labelled display and if possible, a backlit screen so you can see when it’s dark. Additionally, opting for a digital screen will make it easier for you to explain to your heating engineer if something goes wrong.

  1. Smart-Tech compatible

If you’re not already using Smart-Tech in your home, there’s a good chance you will be soon. Making sure your new boiler is compatible will future proof your home and guarantee it stands the test of time.

When searching for a new boiler, check it’s OpenTherm compatible. This technology lets your boiler communicate with a room thermostat, which means you can connect a compatible smart thermostat and possibly control your heating and hot water from your mobile device.

  1. Warranty

Any appliance you buy comes with a warranty. No one ever wants to use it, but it’s nice to know it’s there. It’s not the most important thing when it comes to buying a boiler, but if having a decent length guarantee puts your mind at ease, it’s worth it.

Our WH range comes with a five-year warranty as standard, which can be upgraded to seven years for a fee.
