    Ideal for large homes and commercial properties, the GB162 boiler is supplied with a standard 2-year manufacturer warranty and will set you back anything between £1,975.50 and £3,566.44.

    Boiler Energy Efficiency Credentials

    The GB162 is a market leading energy-saving boiler with an efficiency rating of 93%, making it an A rated appliance. To ensure the boiler matches your demand for heat, it will modulate its output down to less than 20% or 25% – depending on your chosen boiler output. This also helps to considerably reduce fuel consumption and improve efficiency. For maximum efficiency and user comfort, you can use the boiler with a selection of optional intelligent controls, such as a weather and load compensation. The GB162 is also compatible with the Energy Management System (EMS) modular controls platform, which keeps the boiler in condensing mode for as long as possible to optimise performance and minimise energy usage.

    GB162 Technology and Main Advantages

    Boasting advanced high-efficiency technology, this boiler by Worcester Bosch has an ALU-Plus heat exchanger which allows for a rapid transfer of heat and increases both durability and heating efficiency. The heat exchanger is combined with a well-insulated case to ensure the appliance remains quiet when in use, which is great news if you plan to keep the boiler in or near one of your busiest rooms or work areas.

    As we mentioned above, the GB162 can achieve high levels of efficiency when demand for heat is low because it can modulate its output down whilst matching your requirements at all times. This can help to lower electricity consumption by up to 40%. And if you have a very high demand for heat, you can combine up to 8 GB162’s to provide a combined output of up to 800kW.

    The appliance features frost protection, is suitable for either open or room sealed flues and integrates with solar thermal installations. Worcester Bosch has also kept the installer in mind by providing them with easy access to all of the components to improve installation and maintenance speeds.

    Is the GB162 System the Right Boiler Type and Size for Your Home?

    This boiler is designed for large homes and is perfect for commercial applications including offices, hotels and factories, especially since it can be combined as part of a multi-boiler cascade system. It does require a hot water cylinder – or more than one in some case. Obviously, the higher the output, the more water the boiler can heat. Like we always say, you will need to ask a Gas Safe engineer to assess your heating and hot water usage habits to help you determine the right output for your home or business.
