Why you should choose Worcester Bosch Boilers

What is a system boiler?


What type of condensing boiler is for me?

There are 3 different types of high-efficiency condensing boiler:

  • Combi
  • Regular
  • System

A regular boiler is often also referred to as a "traditional" or "conventional" boiler.

Each type delivers all the benefits of high-efficiency technology, but which one you choose will depend on several factors, including your property, your lifestyle and the professional advice of your CORGI (gas) or OFTEC (oil) registered installer.
What is a system boiler?

Unlike a combi, both a system boiler and a regular (conventional) boiler work on the principle of stored hot water -- but a system boiler differs from a regular boiler in some important respects.

Many of the major individual components of the heating and hot water system are built in, which means that installation is quicker, neater, easier and more efficient.

The boiler includes an expansion vessel so there is no requirement for a feed and expansion tank in the loft, which allows the installation to save space.
