Flexible system solutions

GB162 boilers have been developed to allow specifiers and heating engineers greater flexibility to design heating systems, providing reliability and efficient performance whatever the scale of the project.

In addition, Worcester also offers a comprehensive on-site technical service where our system specialists can visit and discuss the best heating system solutions for your particular needs.
