Worcester Bosch Boiler Models

Worcester Bosch has also received Which? recognition for 16 years, solidifying the brand’s reliability. They design energy-efficient and durable boilers. Explore our range below.

Greenstar 8000 Style Combi Boilers

The Greenstar 8000 Style is a premium combi boiler designed to provide strong heating and hot water performance. It has a cleaner, more modern look than many standard models. The larger output options also make it perfect for larger or busier households with greater hot water requirements, while its 94% efficiency rating can help reduce energy consumption and household emissions.

Greenstar 4000 Combi and System Boilers

The Greenstar 4000 is a practical middle-ground if you want something modern, efficient and flexible. The combi version provides heating and instant hot water from a single appliance without a separate cylinder. The system version works alongside a hot water cylinder, making it great for homes with higher hot water demand.

Greenstar 2000 Combi Boiler

The Greenstar 2000 is a compact combi boiler aimed at homeowners looking for an affordable and straightforward Worcester Bosch option. Combi boilers provide heating and hot water from one unit, making it a practical, no-fuss choice for everyday heating needs.

Greenstar i Gas Boiler

The Greenstar i Gas Boiler is designed to provide dependable heating for a range of domestic properties. Available in 25kW and 30kW versions, it can suit a wide range of smaller and medium-sized homes and provide reliable performance over long periods of time.

Greenstar Si Compact Gas Boiler

The Greenstar Si Compact is a useful choice when boiler installation space is limited. Its smaller design makes it easier to work into tighter kitchens, cupboards and utility areas, which can be especially helpful in homes where every bit of storage matters.

Greenstar Heatslave II Oil Boiler

The Greenstar Heatslave II is designed for homes that rely on oil heating rather than mains gas, making it useful for rural and off-grid properties. It combines heating and hot water in one floor-standing unit and comes in several output sizes, giving homeowners more flexibility when choosing a model for their property.

Greenstar Highflow CDi Boiler

The Greenstar Highflow CDi is designed for busy households. Its floor-standing design gives it more presence than a standard wall-mounted boiler, but that extra size helps it cater for larger properties and heavier use. It can be a particularly useful choice for families that regularly use multiple bathrooms.

GB162 System Boilers

The GB162 system boiler is built for much higher outputs and can be suitable for larger properties and commercial heating applications with greater heating demands.

Our Gas Safe registered installers will help narrow down the right model for you, considering factors such as property size, radiator count and household demand.

FAQs about Worcester Bosch

Got questions about our Worcester Bosch boilers? Here are the answers homeowners ask us most.

Yes, a new Worcester Bosch boiler can last around 10-15 years and suits homeowners looking for a reliable, budget-conscious option.

It’s worth noting, however, that Worcester Bosch boilers use an aluminium heat exchanger, which is shown to lose as much as 10% of its efficiency over 10-years. However, the choice of an aluminium heat exchanger allows their boilers to be more budget-friendly.

The total cost of a Worcester Bosch boiler will depend on more than the model itself, as your existing system and any extra installation work can affect the final price. Selected boilers are also available with guarantees of up to 12 years, depending on the model, installer and installation conditions.

Yes, every model in the current range is 20% hydrogen-ready. This means that if a hydrogen and natural gas blend becomes available in the UK, current models will be able to switch over.

Yes, but you will need a Worcester Bosch EasyControl adapter for your boiler and a 230V room thermostat.

Yes, some compact models can be fitted in a cupboard space. However, different models come in different sizes, and large storage combi boilers will not fit into a standard-sized cupboard. Models with a cold water tank will need enough space for the boiler and the tank, which is why it’s vital you choose the right boiler suitable for your home.

Nest thermostats are designed to work with a wide range of heating systems, including Worcester Bosch boilers. It may work with your boiler, but Boilerhut doesn’t install Nest systems.

Nest systems generally don’t cover a boiler’s warranty, and if, for any reason, the Nest stops working, you could be left without heating.

At Boilerhut, we no longer fit or recommend Nest for this reason. We recommend the Vitotrol 100-E for Viessmann boilers or the Tado thermostat if you want to use smart TRVs.

If your Worcester Bosch boiler has a faulty heat exchanger, the best option will depend on the boiler’s age, condition and repair cost. A qualified heating engineer can assess the fault and explain whether repair or replacement is more appropriate. For an older boiler, replacing it may provide a more efficient and reliable long-term solution.
