Our thoughts on the Worcester Bosch Greenstar 8000 Style 

The Worcester Bosch Greenstar 8000 Style has a radiant design and boasts a high energy efficiency rating for such a powerful boiler. If you are looking to prioritise reduced carbon emissions and lower bills with your new boiler, it may be a boiler you are considering. However, it is at this point that we should highlight that whilst the energy efficiency of the Worcester Bosch Greenstar 8000 Style is great on paper, this, unfortunately, won’t last forever. 

Equipped with an aluminium heat exchanger

The reason the efficiency won’t last forever is down to the heat exchanger. Whilst this is great for thermal conductivity and heat transfer, it’s not so great for corrosion resistance. The reason being that aluminium is prone to rust and this corrosion will affect efficiency over time. So whilst the boiler is advertised at 94% efficiency, this won’t be the case forever. Whilst heat exchanger issues will be covered as part of the warranty, once out of warranty the repair costs for this will be costly. 

It’s not called Style for nothing…

It’s right there in the name. The Worcester Bosch Greenstar 8000 Style would be doing something wrong if it wasn’t designed to look good – and it does. Available in high gloss black or white, with a stunning blue digital control panel, it won’t ruin your décor that is for sure.

Control options galore

The Greenstar 8000 Style includes technological innovation designed to enhance heating and hot water performance.  It is compatible with the Worcester Bosch smart energy management system EasyControl, Amazon Alexa and Google Assistant – so you can control your heating from virtually anywhere. But even the standard controls have been designed to be as easy to use as possible.

Assembled in the UK

The Worcester Bosch Greenstar 8000 Style is assembled in the Worcester Bosch factory in Worcester, UK as are the other models in the Greenstar range. However, it is made up of components that are purchased from third-party companies. This is a negative as there are equivalent boilers at a similar price point that utilise components that are all made in-house. The benefit from these competitors is that their components are designed to work efficiently with each other.

As this model is assembled in the UK, parts are widely available though. 

Plastic parts

With that said, a downside to the Greenstar 8000 Style is that many of the parts utilised within it are made from plastic and are more prone to perishing than boilers containing higher quality brass parts.

Reputation and quality

The Greenstar range (which the Greenstar 8000 Style belongs to, alongside its sister model the Greenstar 8000 Life) has won the well-respected Which? Best Buy award for ten years in a row. 

Commitment to energy efficiency 

The Worcester Bosch Greenstar 8000 Style is a combi boiler that doesn’t require a water tank. It uses a heat exchanger to heat water when needed – and because of its power, it can comfortably provide water for homes with 2 or more bathrooms.

The Greenstar 8000 Style is initially 94% energy efficient and has an ErP ‘A’ rating. When used in conjunction with smart technology, energy efficiency can be even higher as you can take steps to reduce wasted energy in your home.
