Worcester Bosch Boiler Prices & Costs

Worcester Bosch is well known for the quality and reliability of the boilers. But, while these are incredibly important, most of us also have a budget that we need to stick to as well.

In this article, we’re going to look at some of the most popular models and provide you with Worcester Bosch boiler prices for their full range of heating solutions.

Worcester Bosch Combi Boilers Prices Range From £655 to £2,603 Including The New 2021 Models

Combination, or combi, boilers are the first choice for most homeowners. Their ability to instantaneously heat water on demand means you no longer have to worry about being last in the bathroom in the morning!

And because there’s no storage of the heated water, then there’s no heat to lose. That then means that they can achieve incredibly high levels of efficiency. All of that means that you can keep your energy bills lower while also doing your bit for the environment.

Worcester Bosch Greenstar 2000 From £655

The Greenstar 2000 is the lowest priced combi boiler on offer from Worcester Bosch. This is an excellent choice of boiler for apartments or for a small/medium one bathroom home. One of the key features which makes it such a good fit for smaller properties is its incredibly quiet operation. That means that it can be installed in the kitchen without the noise being intrusive.

We love the quick tap functionality, which reduces water wastage. All you have to do is open the tap and then immediately close it again. The boiler recognises the need to supply hot water, and so as soon as the tap is closed, the boiler comes to life and brings the plate heat exchanger to the hot water set point. Just thirty seconds later, you can reopen the tap, and your hot water is available. No more water down the drain while you wait for the water to heat up.

The warranty is a little lower at five years as standard, but if you have the Greenstar System Filter fitted at the point of installation, then the warranty goes up to 6 years. Worcester Bosch describes the Greenstar 2000 as ‘the best boiler not very much money can buy’, and we think that’s the perfect way to think about this model!

Worcester Bosch Greenstar 4000 From £822

A step-up from the Greenstar 2000, the 4000 model is built upon the features of the Greenstar i. It’s available in two different power outputs, 25 and 30kW and can be an excellent choice for areas where the water pressure is low but where you still want to have a powerful and warm shower.

The 4000 model also features the quick tap functionality, and when combined with the speed and efficiency of the combi boiler, you can always have hot water whenever you need it.

Wireless connectivity is available via the Bosch EasyControl system. This is a smart connected thermostat which then makes it incredibly easy to control your heating and hot water resulting in energy savings and a reduced gas bill. No more wondering whether you turned the heating off when you go out; with the Greenstar 4000, you can turn it on and off from your phone no matter where you are.

The standard warranty on the Greenstar 4000 is seven years, but you can increase that to 8 years if you have a Greenstar filter fitted during installation and take it right up to 10 years with the fitted filer and an additional payment.

Worcester Bosch Greenstar i From £925

The Greenstar i is the most popular boiler in the Worcester Bosch range, and it’s a great choice of boiler for small to medium homes with one bathroom. It’s designed to fit between wall-mounted kitchen cupboards making it easy to find an installation spot. But the small size of the Greenstar i doesn’t mean to say that it’s not a powerful boiler; it can fill a standard kitchen sink with hot water within 45 seconds.

Many of us have a preferred way that we like to set up and monitor household appliances, and Worcester Bosch has taken this into account with the Greenstar i. If you prefer a more traditional method, that’s fine as you can have a mechanical timer fitted. But if you like to be able to control everything via your smartphone, then that’s an option as well.

One common boiler problem comes from the condensate pipe becoming frozen. But Worcester Bosch has cracked that problem by ensuring that on the Greenstar I, that the condensate discharge is resilient to freezing right down to -15’C. That all means no more worries about boiler problems when the temperatures begin to drop.

Worcester Bosch Greenstar 8000 Life Combi From £1,015

Despite being a wall hung range of combi boilers, the Greenstar Life is one of Worcester Bosch’s most powerful heating systems. And it’s not all about functionality because the Greenstar 8000 also features a new modern design which makes all the difference to the ease with which this boiler can be controlled.

it’s seen improvements to the display screen combined with more straightforward to use push buttons. It’s also now compatible with Bosch’s EasyControl, meaning that you can access all the settings no matter where you are in the world.

One new technological feature is the boiler’s ability to monitor the system pressure and to then keep it at an optimal level. That then means that there’s no need for you to have top up the boiler with additional water; it’s all taken care of for you.

The Greenstar Life is available in five different power outputs, from 30kW right up to the powerful 50kW, which is then suitable for larger homes with more than one bathroom.

Worcester Bosch Greenstar CDi Highflow From £1,785

If you want the convenience of a combi but have struggled to find one with the power to cope with the needs of your large home, then the Greenstar CDi Highflow could be the solution.

With the capability of producing 25 litres of hot water per minute with rapid reheat times, this is a boiler that can cope with hot water demands from several outlets all at the same time.

This floor-standing boiler fits perfectly under a kitchen worktop. If however, space is tight in the kitchen, then it can also be fitted into a garage or cellar with the inbuilt frost protection preventing any problems during cold spells. If you’re not able to access a natural gas supply, the Greenstar CDi Highflow is also available for LPG connectivity.

Worcester Bosch Regular Boilers Prices

You may know a regular boiler as a traditional, conventional or heat only system, but all four names refer to the same type of boiler. These require room for a hot water cylinder as well as having a cold-water storage tank positioned up in the loft.

While these tend not to be a boiler of choice for installing within a new home, they are ideal for properties that already have a regular boiler fitted and are looking for a replacement of the same type. As with the combi and system boilers, Worcester Bosch has a wide range of choice to ensure that there’s the right regular boiler to meet your needs. You could always change to a combi to update your home and possibly save money in the long run, but the initial new boiler cost will be more due to the labour costs for changing boiler type.

Worcester Bosch Greenstar FS CDi Regular From £1369

The Greenstar FS CDi Regular is a great replacement model for an older floor standing boiler. It neatly fits under a standard worktop counter and is capable of providing hot water and hearting to larger homes.  It’s compatible with the high-efficiency Greenstore cylinders that then ensure hot water is quickly replenished when used, meaning that there’s always a stored supply for when you need it.

The Greenstar FS CDi regular boiler is also compatible with Greenskies solar panels for even higher energy savings. This model can be controlled through the Bosch EasyControl system but do bear in mind that you’ll also need an EasyControl adaptor for it to work with a regular boiler.

Worcester Bosch Greenstar Ri From £679

This is one of Worcester Bosch’s most compact boilers, measuring in at just 600mm high, 390mm wide, and 270mm deep. This then makes them the perfect choice for fitting into the space of a standard kitchen cupboard. With a weight of under 23kg, they’re also an engineer’s favourite due to the quick and easy installation. The Greenstar Ri comes with the added advantage of not needing any additional ventilation, so there’s no need to add an air grill to the cupboard.

If you need to fit the boiler in the garage or basement, the Greenstar Ri provides the reassurance of built-in frost protection for the colder months.

The Greenstar Ri offers a number of different power outputs, so it can seem tricky to decide which one is the perfect match for your home. Here’s our guide to which one to go for:

Greenstar 12RiSmall house: 2-3 bedrooms6-7 radiators120 litre hot water tank

Greenstar 30RiLarge house:  4-5 bedrooms12-14 radiators200 litre hot water tank

Worcester Bosch GB162

Although the GB162 is popular in commercial settings, it can also be a good choice for larger households. With the anticipated high volume hot water and heating requirements, this boiler is available in four outputs ranging from 50kW, right the way through to 100kW. And if that’s not enough, the GB162 can form part of a cascade system of boilers allowing up to eight to be connected.

Despite the impressive output, the GB162 System has still achieved an ErP ‘A’ rating. That means that you can be confident in its highest levels of efficiency. We really like its automatic ability to reduce the output by 30% or less, depending on your heating requirements. This gives a double whammy through the reduction in your gas bill while also reducing energy use and its consequences for the environment.

Under the cover, the GB162 utilises the award-winning ALU-Plus heat exchanger. This means that it’s incredibly resistant to corrosion while also being very quick to warm up. As a result, you’re not then wasting heat through the need to warm up the heat exchanger for long periods before it can then switch to providing you with hot water. The GB162 also features built-in frost protection to ensure there’s no interruption to heating, no matter the temperatures outside.

Worcester Bosch System Boilers Prices

While needing a cylinder to store hot water may seem a downside, it does mean that there is a constant supply of hot water no matter the number of taps that are in use at the same time.  Unlike the regular boilers, there’s no need for tanks in the loft, so that removes any problems from not having free space in the loft or if you are planning a conversion to living space.

If you’re looking towards alternative fuel supplies, the Worcester Bosch system boilers are also compatible with solar heating systems.

Worcester Bosch Greenstar 8000 Life System Boiler From £1,034

The Greenstar Life system boiler builds upon the success of the award-winning Greenstar CDi Classic. In comes a modern new design which is available in white or in high gloss black.

The whole aim of this model is to make heating your home efficiently as easy as possible.  Upgraded controls and Wi-Fi connectivity form part of this package, and the model also includes the Intelligent Filling System. This ensures that the system pressure is always maintained at an optimum level.

Aimed at the larger household with multiple bathrooms, the Greenstar life is available in five different power outputs ranging from 30 through to 50kW.

Worcester Bosch Greenstar i System From £725

These two models offer the highest output of Worcester Bosch’s latest generation of smaller and more lightweight boilers. This makes them an excellent choice no matter the size of your home. The boilers also feature a low energy pump which reduces electricity usage resulting in lower utility bills.

Ease of use is built-in with straightforward control knobs and a user-friendly display panel to easily see status codes and temperature readings. If you’re interested in utilising natural sources of power, the Greenstar I System boilers are also compatible with Greenskies solar panels.

An additional energy-saving setting for this boiler comes from being able to disable the Preheat Function and instead utilise Eco Mode. Preheat heats the cylinder more frequently, which then tops it up the temperature for a quicker heat-up process. Eco mode uses less energy by maintaining the water at a slightly lower average temperature.

Worcester Bosch Greenstar 4000 System Boiler From £790

The Greenstar 4000 is a great for medium sized homes with one bathroom. It’s got a new modern design easy to read full-colour text display, and it’s the quietest system boiler within the Worcester Bosch range.  With five different power outputs from 12kW through to 24kW, there’s an opportunity to find the perfect match for your home heating needs.

All five of the boiler versions have achieved an ErP Efficiency rating of ‘A’. This means that if you currently have an older, less efficient boiler installed, you could be save up to £312 a year when comparing an ‘A’ rated system to one that’s been assessed as an ‘F’.

As well as lower gas bills, an efficient boiler will also provide more reliable heating, and it’s better for the environment, too, with less carbon being dispersed into the atmosphere.
