Here is our review of the Worcester Bosch Greenstar 8000 Style Combi Boiler

Worcester Bosch Greenstar 8000 Style Performance review

This large capacity condensing combi boiler is designed to handle higher demands for hot water and heating.

It’s a great choice for larger homes with two bathrooms or lots of radiators or underfloor heating.

The Style range of boilers is similar to the brand’s Life range, but it has an even greater focus on design.

The boiler has all of the same features of the Life boiler, including offering options 30kW, 35kW, 40kW, 45kW and 50kW, so you can choose the one that meets the needs of your home.

4 bed home

The Worcester Bosch Greenstar 8000 Style has the highest water flow rate of any wall-hung combi boiler on the market.

The Bosch Worcester Greenstar 50kW model has a hot water tap flow rate of 20.3 litres per minute at 35 degrees or 17.9 litres per minute at 40 degrees.

It can comfortably heat large homes and those with two or more bathrooms.

Like the Worcester 8000 Life boiler, it has an intelligent filling system, which helps to keep the boiler at the correct pressure without having to fill the boiler using the filling loop manually.

It’s also one of the quietest boilers that Worcester Bosch has available.

Combined with its style, this means you could install it into any room in your home without worry.

Energy Efficiency of the Worcester Bosch Greenstar 8000 Style

Energy efficiency is a top priority for all boilers.

New boilers, when installed, need to have an energy efficiency of at least 92% according to regulations. Most new boilers are now hydrogen-ready boilers to 20% blend too. All Worcester Bosch boilers are hydrogen blend ready. 

The Worcester Bosch Greenstar 8000 Style has an energy-efficiency of 94%, matching the Life boiler and beating out many others on the market that just meet the minimum.

The boiler has an A-rating for both heating and hot water, and the increased modulation ratio of 1:10 helps to improve fuel efficiency too.

Another benefit for this Worcester Bosch comfort boiler is that it offers smart features.

In addition to the Worcester intelligent filling system, which will automatically detect when the heating system needs to be repressurised.

It can also be connected to smart thermostats such as Hive and Nest and your preferred smart devices such as your smartphone or tablet. see our Hive Vs Nest review here if you think these could be for you.

Using Bosch EasyControl, you can control your heating and hot water from anywhere, which means you have more control over how much energy you use.

The hot water flowing through your central heating will be at its peak with the 8000 Style.

Boiler Size and Installation review 

The Worcester Bosch Greenstar 8000 Style measures 400mm x 780mm x 365mm.

It’s on the larger side, but its sleek style means that it will look good wherever you choose to install it.

It’s available in black and white, so you can select the colour that will look best in your home.

The design-led boiler almost looks more like a high-tech speaker than a boiler, and any style enthusiast would be happy to have it in their home.

Not having to hide it away in a cupboard makes it easier to install, and it’s also lightweight, which also helps with the installation.

If your looking for a more compact Worcester Bosch boiler check out the Worcester 4000 combi or even the Worcester 2000 for a much cheaper option.
