How does a system boiler work?

Unlike an ‘on demand’ combi boiler, these boilers heat water and store it in a hot water cylinder which can be installed in a convenient location, like your airing cupboard.

A warm home doesn’t have to be costly. We’ve got a range of flexible payment options available – you can spread the cost of a boiler for up to three years with 0% APR Representative.1 We are a credit broker and not a lender.
