System Boilers in Wokingham – Install, Repair & Servicing

What Is a System Boiler?

A system boiler is a gas boiler that heats both your central heating and hot water. Unlike a combi boiler, it stores hot water in a separate unvented cylinder and does not require a cold water tank in the loft.

This setup provides:

• Powerful showers and strong water pressure

• Simultaneous hot water use in multiple bathrooms

• Quicker and tidier installation than traditional heat-only boilers

How System Boilers Work

System boilers work with a sealed heating system, usually around 1.5 bar, and heat a separate hot water cylinder. The boiler provides hot water for central heating and replenishes the cylinder, ensuring consistent performance.

Key features include:

• Built-in pump and expansion vessel

• Compatibility with solar thermal systems

• Constant hot water availability
