Product Description
The Worcester Bosch GB162 low energy modulating pump group provides a reliable,

fast, and easy connection between a boiler and main flow, return, and gas headers.

This product is designed to reduce running costs and component wear and tear and improve the efficiency of your system.

Product Features
Includes insulation cover, isolating valves, gas valve, and connections
Sized to ensure that the flow rate through the GB162 heat cell won’t exceed the limit of 5000L/h at T 20K
Minimises wear and tear on components
Improves system efficiency
Reduced installation and running costs
Simplifies hydraulic design of a heating circuit
Reduced noise and energy use
Pump groups directly mounted under the boiler to feed a low-loss header or plate heat exchanger or,

in the case of single 50kW and 65kW boilers, to supply a system directly
As heating circuits reach the required temperature and flow is reduced by the thermostatic radiator valves,

the WILO modulating pump responds to the reduced demand
