Product Description

Designed and manufactured by Worcester Bosch, the GB162 gas boiler is a powerful wall mounted system boiler with an output rating of 99.5 kW.

How efficient is the GB162?

This boiler has a seasonal efficiency of 95.3% which can increase to 98.3% when the boiler is operating at 30 % of rated heat output and low temperature regime.

Is the output rating suitable for my home?

The output rating of 99.5 kW is higher than is needed for domestic properties and is best suited to commercial settings. For even higher output, up to 8 GB162 boilers can be installed as part of a multi-boiler cascade system.

What options are available?

This is the most powerful boiler in the GB162 range with smaller outputs of 50 kW, 65 kW and 85 kW also available.

Is a system boiler suitable for my home?

System boilers must be installed as part of a heating system that also includes a hot water cylinder to store the hot water heated by the boiler for use at a later time. This means that they’re able to meet higher demands for hot water – ideal for homes with multiple bathrooms.

How long is the warranty?

Worcester Bosch have attached a 2 year warranty as standard to their range of GB162 system boilers.

What are the key features of GB162 boilers?

The ability to add more than one GB162 boiler via the multi-boiler cascade system (from 1 to 8 boilers) allows you to create an incredibly powerful heating system. You can take control of your heating from wherever you are with the Bosch EasyControl and it can be integrated with solar thermal to help lower your energy bills.

How big is this boiler?

Despite being powerful, this boiler has compact dimensions of 1,329 x 520 x 465mm (HxWxD).
