  • What is a System Boiler? Pros, Cons & Costs | Boiler Guide

    Installation of a system boiler can be easier, quicker and neater than the installation of a regular boiler. This is due to many of the individual components of the heating and hot water system being built into a system boiler. By building in components, the unit is more compact and only requires a cylinder that can be stored in an airing cupboard.Learn More
