What is a Gas System Boiler?

A system boiler, just like a regular (conventional) boiler works on the principle of stored hot water. However, a system boiler differs from a regular boiler in some important respects.

Firstly, many of the major individual components of the heating and hot water system are built into a system boiler, which means that installation is quicker, neater, easier and more efficient

Secondly, the hot water is pumped from the system boiler through the heating system to the radiators and hot water cylinder, resulting in a fast response and more economical running costs. The system boiler removes the need for a feed and expansion cistern.

The Benefits of Gas System Boilers

  •   Can provide plentiful and consistent hot water for properties with high hot water demand e.g. more than one bathroom
  •   Economical to run and kinder to the environment because a system boiler uses less fuel
  •   Neater, easier and quicker installation because most major components of the heating and hot water system are already built in
  •   No feed or expansion cistern in the loft saves space and eliminates the risk of any leaks or frost damage to pipes and tanks
  •   Constant supply of hot water to taps, baths or showers without water running cold elsewhere in the house
  •   High flow rate thanks to the in-built pump which delivers powerful showers and quick filling baths
