Worcester Bosch Combi Boilers Price Range – Reliable & Energy Efficient

With combi boilers now being the most popular type of boiler in the UK (installed in 70% of British homes), a Worcester Bosch combi boiler is a highly efficient, practical hot water and heating solution for your home. Combi boilers provide central heating and hot water without the need for a separate tank to store water and so can be tucked away in cupboards, under stairs or in kitchen cabinets. Combi boilers are especially useful if space is limited, and the Worcester Bosch combi boiler range ensures high energy efficiency and a 5 year guarantee. Prices range from £767 to £2033 with varying sizes and specifications.

Each series in the Worcester Bosch combi range is designed to suit the needs of different homes and lifestyles, such as:

Worcester Bosch Regular Heat Only Boilers Price Range – High Flow Rate, High Demand

Worcester Bosch regular boilers (also known as ‘conventional’ or ‘heat only’ boilers) provide hot water and heating via a boiler, a storage cylinder which is usually housed in an airing cupboard and, water tanks in the loft. Regular heat only boilers are best suited for larger homes with an existing heat only boiler and are beneficial as more than one tap can be used at a time with no reduction in flow rate. Worcester Bosch regular boiler prices range from £759 – £1847 with varying sizes and outputs.

The Worcester Bosch regular boiler range offers A-rated solutions for homes of all sizes. Regular boiler options include:

Worcester Bosch System Boilers Price Range – The Best of Both Worlds

System boilers (often referred to as a ‘sealed systems’) provide central heating and hot water via a storage cylinder which is usually housed in an airing cupboard. Worcester Bosch system boilers provide instant hot water and more than one tap can be used at any one time without a reduction in flow rate. The main drawback to this type of system is that once the water stored in the tank has run out, you have to wait for it to reheat. Worcester Bosch system boilers are energy efficient (like all Worcester Bosch boilers) and come with a 5 year guarantee. Prices range from £824 to £1062 with varying sizes and specifications.

Worcester Bosch’s System Boiler Range is Designed with All Sizes of Property in Mind, and includes the Following Options:

Worcester Bosch Oil Boilers Price Range – Designed for Homes Not Connected to the Gas Network

One of the most common types of heating alternatives for those living off the mains gas grid is oil-fired boilers. Even though they use oil instead of gas to heat water, oil boilers are still highly efficient. However, all oil-fired boilers need to be connected to a special outdoor tank that stores the oil, and the oil itself has to be delivered to your home by road. Like Worcester Bosch gas boilers, the brand’s oil boilers have secured Which? Best Buy status and come in different types including combi, system and regular boilers to suit most requirements. Prices vary from £1,300 to £2,750, and each oil boiler in the range is backed by a 2-year warranty as standard.

Some Worcester Bosch oil-fired boilers can be installed indoors, whereas others must be located outside and will include the word ‘External’ in their name. Below, we’ve listed the full range of Worcester Bosch oil-fired combi, system and regular boilers and what size of property they best suit:

COMBI OIL BOILER SERIES SIZES SIZE OF HOME PRICE
Greenstar Heatslave II 18 – 32kW Small, medium and large-sized homes £2,200 – £2,500
Greenstar Heatslave II External 18 – 32kW Small, medium and large-sized homes £2,400 – £2750

Worcester Bosch Boiler Problems and Repairs

While Worcester Bosch boilers offer quality and reliability, things can still go wrong now and then. No boiler is immune from problems, which is why it’s so important that you have your Worcester Bosch boiler serviced every year. If you’re experiencing an issue with your Worcester Bosch boiler, you can find out more about Common Worcester Bosch Boiler Problems and Repairs in our expert guide. Our guide should help you to identify common boiler faults, as well as help you to determine what you need to do next to get your Worcester Bosch boiler running smoothly and efficiently again.

Worcester Bosch Boiler Fault Codes

When your Worcester Bosch boiler develops a fault, a fault code or error code will usually appear on the boiler itself. The fault code should help your engineer to identify and diagnose any problems with your boiler so that they can resolve it as quickly as possible. Some fault codes won’t be serious enough to call an engineer, which means you might be able to fix the issue and clear the fault code yourself. Having said that, most Worcester Bosch fault codes will require the attention of a qualified Gas Safe registered engineer. If your boiler is displaying a fault code, our guide to Worcester Bosch Boiler Errors and Fault Codes should help you find out what the code means.

Worcester Bosch Boiler Warranty

No matter which Worcester Bosch boiler you choose, your appliance will come with a manufacturer-backed warranty, ranging from 2 to 5 years in length. The warranty ensures that you won’t pay for any material or manufacturing faults for the duration of the warranty period. However, all Worcester Bosch boiler warranties come with strict terms and conditions which must be respected to keep the warranty valid. Worcester Bosch offers ‘no quibble’ warranties and sometimes exclusive extended warranties, but you must register the warranty to reap the full benefits. Our Worcester Bosch Boiler Warranty guide explains everything you need to know about your boiler warranty.

Worcester Bosch Boiler Controls

Worcester Bosch is known for manufacturing energy-efficient boilers that provide high levels of performance, but the brand also makes a selection of optional boiler controls to enhance comfort levels and improve your boiler’s efficiency. You can choose from a wide range of Worcester Bosch boiler controls, such as mechanical timers, digital programmers and innovative smart thermostats that can be controlled using an app on your smartphone. These optional controls are designed to not only make it easier for you to control your heating and hot water system but also to help you save more energy, which means you’ll also save more money on your bills. If you would like to know more about the different options available, you can read our helpful guide to Worcester Bosch Boiler Controls.
