How to choose a boiler for your home

A new boiler will be one of the more expensive purchases that you will make as a homeowner. So it’s important to choose the right boiler, from the right people, that will last. At Vaillant, we’re here to help you every step of the way.

1. What boiler do you have?

Most homes in the UK use a gas boiler and heating system to keep things toasty. However, if you’re purchasing a new boiler you may not want to choose a like-for-like replacement; upgrading to a more modern solution to save money in the longterm, or swapping to a solution that better suits your needs.

There are three main types of gas boilers available; combi boilers, system boilers, and conventional vented boilers (sometimes called “regular” boilers). We explain how to figure out what kind of boiler you have, and share the benefits and drawbacks of each type so you can make an informed decision.
