Worcester Bosch Boilers: Compare Reviews, Prices and Warranty on all Models
In 1996, when Worcester joined forces with the Worldwide Bosch Group, they came together to form a powerhouse in the manufacturing business. With Worcester’s production history spanning back to the 1960s and the global renown of Bosch’s advanced technology, Worcester Bosch was born.
Since then, they have gone on to become the UK market leader in domestic boilers and over the last 50 years have earned high acclaim and recognition with multiple awards. They have even received the Royal Warrant to supply boilers to Her Majesty The Queen’s Sandringham Estate.
Worcester Bosch not only produces boilers, in both gas and oil fuel options, but they now offer a wide range of renewable heating technologies such as heat pumps, solar water heaters and smart controls.
The Worcester Bosch boiler range
The Worcester Bosch boiler range includes a number of different models, with options for different types of fuel. As well as their natural gas boilers, they also offer a large range of oil boilers for homeowners who are not connected to the national gas grid.
Of their gas boiler range, every available model is 20% hydrogen ready, meaning that if a hydrogen blend gas becomes available in the future, these boilers will be ready to benefit from the switch over. This is a great advantage as it future-proofs these units in a way that will benefit the environment and save you money, as you won’t need to upgrade.
Worcester Bosch provides each type of boiler: combi, system and regular (also known as conventional). They have a range of models for each with different power outputs and fuel options to suit many types of home.
The Worcester Bosch range is known as the ‘Greenstar’ range and they consist of gas, oil and LPG (liquified petroleum gas) compatible units. The most recognised models within the range include the Greenstar 4000 and 8000 gas boilers and the Greenstar Heatslave II and Danesmoor in the oil boiler range.

Regular boilers, also known as ‘traditional’ or ‘conventional’ boilers, are usually found in large, older style homes. They require a cold water feed tank in the loft, and an additional hot water storage cylinder in order to provide heating and hot water. These boilers are not recommended for newer homes, with existing combi or system boilers, as they require a lot of pipe work and take up space across your home. Newer regular boilers however, are recommended if you wish to update your existing regular boiler, as they are much more efficient and can save you money on bills.

Each home has its own unique demands for hot water and heating and this can depend on things such as how many radiators there are and how many bathrooms. One of the most important things to consider however, is to get a boiler which is powerful enough to meet your requirements, but not be so over sized that it wastes energy unnecessarily. This is a crucial factor, as having too little power can affect your water supply, but using too much power will mean your boiler is burning more fuel unnecessarily and costing you more money.
Thankfully, Worcester Bosch offers a wide range of boiler output sizes across their models, meaning there are options available for any sized home.
