Worcester Bosch manufactures:

• Combi Boilers – For instant hot water and heating, no tank required.

• System Boilers – Require a cylinder for hot water storage.

• Regular (Conventional) Boilers – Work with tanks and are ideal for older systems or larger properties.

Most modern Worcester boilers have an A-rated ErP efficiency (over 90%). This helps reduce energy bills and carbon footprint compared to older G-rated boilers.

You should service your boiler once a year. Annual servicing ensures it runs safely, maintains efficiency, and keeps your manufacturer warranty valid.

With regular servicing and maintenance, a Worcester boiler typically lasts 12–15 years. Some can last even longer if well maintained.
