The Greenstar Range

The multi award winning Greenstar range belongs to the highly successful Bosch group.

Worcester Greenstar has an extensive range of gas, LPG and oil-fired boilers, which are all A-rated, high-efficiency, condensing models. The products are designed to deliver heating and hot water comfort to households, as well as helping to reduce your fuel bills and carbon footprint.

Worcester Greenstar boasts multi award winning boilers having won CORGI’s Domestic Heating Product of the Year, which is voted for by installers, for three years running. The range includes floor-standing models, gas-fired boilers and a wall-mounted series, making installation easier. Every boiler is rigorously tested before it leaves the factory, to ensure it is fit for everyday use.

The combi boilers provide heating and hot water directly from the boiler, while regular and system boilers heat your central heating system and produce hot water for your cylinder.

All gas, oil and LPG boilers by Greenstar run at 90 per cent efficiency. Greenstar boilers are within class five – the lowest of the five categories – for NOx (Nitrogen Oxide) emissions. A Worcester condensing boiler also delivers dramatically reduced emissions of both CO2 and NOx, helping in the battle against climate change.

Worcester Bosch also utilises renewable technologies producing ground source heat pumps and air source heat pumps.

Worcester Bosch Combi Boilers & Prices

They were the pioneer of the combi boiler in the UK, with the Greenstar range developed to suit virtually all homes.

Worcester Bosch combi boilers are both a high efficiency water (A-rated) heater and a central heating boiler in a single compact unit.

They are cost effective and energy efficient as water is heated instantly rather than being heated and then stored in a cylinder.

All Greenstar combis are designed and manufactured to provide high levels of performance and operating efficiency with their ’keep hot’ facility which ensures that hot water is almost instantly available whenever it’s required.

The boilers also incorporate a special ‘ECO’ mode button which can be used to override the ‘keep hot’ facility – thereby using less gas, as energy is only used when hot water is required.

For added efficiency, models such as the Greenstar CDI Classic, Greenstar CDi Compact and Greenstar Si Compact condense in both hot water and heating modes.

Benefits of a Worcester Bosch Combi boiler

• Compact sizes make combi boilers perfect for smaller properties
• Ideal where there is little or no loft space
• No need for a hot water cylinder allows increased living space
