Worcester Bosch Boilers – Prices & Benefits


Worcester Bosch LogoManufacturing boilers since 1962, Worcester Bosch is a British boiler manufacturer with a reputation for innovation. Originally known simply as Worcester, they were acquired by Bosch in 1992 enabling them to expand their operation on a worldwide scale. The company was the first to market with the revolutionary Combi boiler which is now the most common type of boiler installation in the UK.

In recent years, Worcester Bosch has also expanded into renewable energy solutions such as ground/air source heat pumps and solar thermal technology. The brand has made a significant investment in future technologies such as fuel cell boilers. Today, in addition to leading both the domestic and commercial boiler markets, the company holds the Royal Warrant to supply heating systems to the Royal Family’s properties.

    Popular Combi Boilers

    A Combi boiler is an all-in-one appliance which will produce hot water for heating and domestic use on demand. You won’t need a feed tank in the attic or a hot water cylinder which is a great advantage for homes where space is limited.

    The Greenstar i Combi boiler has been installed in over 1 million homes in the UK and is Worcester Bosch’s most popular gas model. It’s ideal for the small to medium sized one-bathroom home and is compatible with a range of heating controls including the Wave smart control. It’s available in outputs of 25 and 30kW. For larger homes this manufacturer also offers the Greenstar CDi Classic and the Highflow CDi and for off-grid homes there is the option of LPG or oil fired models.
