Combi boilers

Combi boilers are becoming an increasingly popular choice for households in the UK.

Conventional boilers

The conventional boilers manufactured by Worcester Bosch could be an ideal choice for most households that have two or more bathrooms or a high demand for hot water. These boilers require a separate hot-water cylinder and a cold-water tank, so are usually easier to install in homes that already have a traditional style of central heating.

These boilers could be an ideal choice for households with more than one bathroom or a high demand for hot-water, as they have the ability to provide hot water to multiple taps simultaneously.

Worcester Bosch boiler range

Worcester Bosch manufacture a variety of A-rated gas & oil-fuelled boiler ranges. Here at HomeServe, we install a number of these ranges into homes across the UK. These include:

The Greenstar i Series

These boilers are typically ideal for smaller properties with one bathroom and a lower demand for hot water and heating. This boiler range replaced the predecessor range of i Junior series boilers in May 2015 and feature a user-friendly control panel that allows you to adjust your heating and hot water to your needs. Other features include a low-energy pump and a “Condensesure Siphon” to help prevent condensate pipe freezing.

The Greenstar Si Compact

These boilers are a typically popular choice for small to mid-sized households with one bathroom and are designed to be easily fitted into a kitchen cupboard. Their user-friendly display is designed for easy use and hot water levels can be easily adjusted to fine tune settings to your comfort. Frost protection is also a feature, which could reduce the risk of frost should you choose to have the boiler installed in your garage or loft.

The Greenstar CDi Compact

Much like the Si range, the CDi range is a compact set of boilers that have been designed to fit easily within cupboard spacing. Irrespective of their compact size, the CDi Compact range are a typically powerful set of boilers that are typically well suited for medium to large properties with one or two bathrooms. Their key features include boiler controls with clear temperature display and a wide choice of functions that are designed for greater comfort and economy.

The Greenstar CDi Classic

This range boasts a high central heating output and tends to be mostly suited to homes with one or two bathrooms. This boiler is recognised for its ease of installation, advanced features and future-proof technology. Key features include an inbuilt keyless filling link to make it easy for you to refill your system and a low energy pump to reduce electrical usage.

Which Worcester Bosch boiler do I need in my home?

Selecting the right boiler system for your home can be a daunting task. Your boiler can be an essential component to your household, providing you with comfortable heat and instantaneous hot water. With such a wide variety of boilers on offer from the Worcester Bosch range, it can be tough to decide which one could be the best choice for your home.

Here at HomeServe, we’re always here to help you make the right choice and it helps that we are accredited Worcester Bosch boiler installers. We supply and install a range of products from this brand and we are ready and willing to answer any of your questions. Whether you’re unsure about choosing a Worcester Bosch combi or a Worcester Bosch regular boiler, we’re committed to helping you make the best choice for you and your family. Once you’ve filled in one of our online quote forms, we can arrange for one of our trained surveyors to visit your home and help you choose a suitable boiler system.

One important factor that you must bear in mind when selecting a new boiler is the kW output that is required for your household. The kW output refers to the boiler’s capability to provide heat and hot water and the power needed for your particular property will largely depend on the number of bathrooms and radiators you have. Generally, the higher the kW output of the boiler, the more demand it can cope with; so, if you have a large household with multiple bathrooms you’re likely to need a boiler that has a higher kW output.

Here’s an estimated guide of kW outputs to help you determine the type of Worcester Bosch combi boiler that would be suitable for your home:

24-27kW 1-2 bedroom, 10 radiators, 1 bathroom
28-34kW 3-4 bedroom, 15 radiators, 1-2 bathroom
35-42kW 4+ bedroom, 20 radiators, 2+ bathroom

(This information has been supplied By Help-Link UK limited and has been produced for information purposes only and should not be used or relied upon as a substitute for professional advice by a suitably qualified engineer.)

Visit our regular and system boiler pages to find out about the kW outputs that could be suitable should you choose to get a different boiler type installed.

Worcester Bosch warranty

All Worcester Bosch boilers come with a standard 5-year manufacturer-backed warranty‡. As a Worcester Bosch accredited installer, we could extend this warranty to 10 years for an additional price upon purchase‡. A valid warranty could help to cover the cost of repairs in the instance that your boiler breaks downs or incurs an internal fault, providing you with added peace of mind. By selecting us to install your new Worcester Bosch boiler, with an extended manufacturer-backed warranty, you could have peace of mind knowing that your boiler has been installed to an excellent standard and that future problems could be rectified by the manufacturer should they arise.
