System Boilers

How are system boilers different from regular and combi boilers, and how can you tell if a system boiler is right for your home? Get the answers to all of this and more on this page, and browse our system boiler prices, too.

What is a system boiler?

A system boiler is very similar to a regular boiler, but with one key difference: instead of getting its water from a tank stored in the attic, a system boiler pumps water directly from the mains supply. System boilers are the least common out of the three key boiler types, as they are neither traditional nor modern. That being said, they do have a number of benefits!

Benefits of system boilers

System boilers are a great all-rounder in terms of their benefits – firstly, since the water comes from the mains, there is no need for a cold water storage tank to be kept in your attic, saving significant space. Having water pumped directly from the mains also means that your water pressure will be optimal, and your boiler will be more efficient. You will be able to access hot water at a quicker rate than with other boilers. Plus, most system boilers are solar compatible

Why choose a system boiler?

Perhaps you are looking to save a little space, benefit from higher water pressure or accommodate more heating and hot water demand as your family grows. Whatever the reason, our gas-safe engineers can help install a system boiler for you in no time, even if you currently have a combi or a regular boiler in place.
