Product Description

The GB162 gas boiler, manufactured by Worcester Bosch, is powerful wall mounted system boiler with an output rating of 84.5 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 84.5 kW is higher than most domestic properties will need and is best suited to very large domestic properties and commercial buildings. This range of boilers can even be installed as part of a multi-boiler cascade system to increase the output further.

What options are available?

In addition to this 85 kW boiler, the GB162 range is also available in output ratings of 50 kW, 65 kW and a massive 100 kW.

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).
