Product Description

The Worcester Bosch Greenstar 8000 Style 40 kW is a highly reliable, condensing wall-mounted combi gas boiler.

How efficient is the Greenstar 8000 Style?

This is a highly efficient boiler that comes with an efficiency rating of 94%, making this an A-rated boiler for heating and hot water. Such high levels of efficiency can help to lower your heating bills.

Is the output rating suitable for my home?

A 40 kW domestic hot water output rating makes this a powerful combi suitable suitable for homes with 2 bathrooms. It also has a central heating output of 35 kW so can heat up to 20 radiators.

Is a combi boiler suitable for my home?

A combi boiler is the best option for homes with 1-2 bathrooms (depending on the output). Properties with 2+ bathrooms should consider a system boiler. This is because combi boilers deliver instant heating and hot water without storing it in a cylinder. This is great for space-saving but does limit the amount of hot water it can provide.

Are there any other options in the Greenstar 8000 Lifestyle range?

You'll have no problem finding a suitable boiler for your home with Worcester Bosch. They offer one of the most extensive ranges of boilers on the market and the Greenstar 8000 Lifestyle range reflects that. Including combi, regular and system boilers with outputs from 30 kW right up to 50 kW.

How long is the warranty period?

With Greenstar 8000 Style boilers, you’ll be covered by a 5 year warranty as standard, with the option of being extended to 12 years when installed by a Worcester Bosch accredited installer.

What are the key features of the Greenstar 8000 Style combi?

Greenstar 8000 Style boilers are available in 2 stylish high gloss colour options (black and white) to help you find a model that will suit your home and have been designed for comfort and long life. This boiler comes with a variety of features and benefits, including an increased modulation ratio of 1:10 to improve fuel efficiency, it prevents on/off cycling, holds more power than any previous Worcester Bosch boiler and thanks to being robust and lightweight, the Greenstar 8000 will help save you time and money on the installation. Plus, it’s compatible with latest intelligent and smart technology, features the first Greenstar intelligent filling system to ensure the boiler maintains optimum pressure without the need to operate a filling link, an improved push button full-colour LCD display, clear text descriptions, and there’s easy access to all internal components. So, when it comes to the annual service, the heating engineer will be able to easily find what they’re looking for, saving you time and money.

Combi boilers are ideal for properties where space is limited as they don’t require any external tanks or cylinders like system and regular boilers. Everything a combi needs to heat your home and hot water is wrapped into a single cost-effective unit.

How big is the Greenstar 8000 Style?

All of the boilers in this range are compact, so they won't take up much space, as shown by the dimensions of 780 x 440 x 365mm (HxWxD).

* This is a guide price for a straightforward, like-for-like boiler replacement. Installation costs will vary dependent on work required.
