Worcester Greenstar 8000 boiler review overview – A big boiler with a bold reputation

As you can see from this quick Worcester 8000 life review, this boiler is big in every sense. It’s big on power with outputs of up to 50kW and is one of the larger new boilers on the market.

It has a big warranty, a big price tag and is big in the style department.

This is a reliable premium boiler, that lends itself to larger homes, but if you like the sound of owning one of these energy-efficient central heating machines, then let’s take a look at what you get included in the new boiler costs.

Worcester Greenstar 8000 combi boiler – How good is it?

Worcester Bosch Greenstar 8000

The Worcester Greenstar 8000 is good. In fact, as you have guessed, from the previous comment it’s very good.

Hailing from the masters at Worcester Bosch boilers who have dominated the UK boiler market for over a decade, the 8000 is their attempt at creating a supercar style boiler.

With a big engine and fantastic looks, they have just about cracked it.

Some may still say it needs to go in a cupboard, but then not everyone is a show-off.

Given a stamp of approval from Worcester with a huge 12 years warranty it clearly is built to last too.

Yes, the Worcester Bosch 8000 life combi boiler is a Which? recommended boiler.

A Which? the recommended boiler is always a good choice so if you ever needed any more reassurance that this is a suitable boiler then you can check out their review too if you have an account with them.

How much does a Worcester 8000 cost?

The Worcester Bosch 8000 costs around £1,300 to buy on its own, not including installation.

If you need this boiler installed, then expect to pay at least £1,000 more, including parts and labour.

When you consider that you can get a Worcester 2000 combi boiler installed for around £1,600 you can see how much more is expected from this boiler.

Although if you do have your heart set on this boiler, you can spread the cost with boiler finance. See the rest of the Worcester Bosch boiler price range here.

Is the Worcester 8000 life combi boiler a replacement for the Greenstar CDi Classic?

Yes, the Worcester 8000 is a replacement for the Greenstar CDi Classic.

Even most of the important components inside are in the same place as the old Greenstar CDi classic making them an even better choice of replacement boiler if this is what you currently have. 

Worcester Bosch Greenstar 30i v 8000 life

As much as the Worcester 8000 is a replacement for the old Greenstar CDi range due to the outputs, it is also a suitable replacement for the 30i.

The Greenstar 30i is one of the most installed boilers in the UK, but this boiler is bigger and more powerful.

If you want a replacement for the 30i you need the Worcester 4000 range, which has the exact fittings and fixtures.

Worcester Bosch Greenstar 8000 Life v Style

The main differences between the Worcester Greenstar 8000 life v style are cosmetic and price. The 8000 style is exactly that, more about the style, which is the high gloss finish front.

This makes the Worcester 8000 style more expensive than the 8000 life.

Worcester 8000 Life 30kw combi boiler review

The Worcester 8000 30kw combi boiler is one of the most popular outputs in the range. This is because it is perfect for medium to large homes in the UK with one to 2 bathrooms.

This combi boiler is the perfect output for this and will run efficiently and effectively, keeping running costs down. It is also the cheapest Worcester 8000, which always helps but it doesn’t make it any less of a boiler.

Worcester Greenstar 8000 Life 35kW boiler

The Worcester Greenstar 8000 life in 35kW is one of the most popular 35kW boilers from Worcester Bosch.

It can heat many homes, typically those with 3-5 bedrooms and an average to high hot water demand.

The 35kW Life and Style are both available in white or black colours and can have long warranties up to 12 years long, which is pretty substantial for a boiler.

If you need a bit more power, consider some of the best 40kw combi boilers

Worcester 8000 Style 50kw combi boiler review

Worcester Bosch Logo

Worcester 8000 50kw combi boiler is the largest combi boiler in the range. It is the most expensive, but it is an absolute monster in terms of boilers.

It can easily power large homes and cope with higher hot water demands.

It may be a better option in some situations than a system boiler and more energy efficient as it will not constantly regulate a hot water cylinder.

If you’re looking for a very powerful combi boiler without a hot water tank, this is perfect for your home.

Main features of the new Worcester 8000

The Worcester 8000 is packed full of new features inside and out. Let’s take a look at what makes this boiler’s price tag justified.

As we have said, this isn’t a small boiler and will struggle to fit inside most kitchen cupboards, but there are both the Style and Life options if you want to show this boiler off or if you want to hide it away and now pay for the gloss finish. 

LCD touchscreen colour display

The 8000 might look a bit daunting or sound it with its all singing all dancing reputation, but using it isn’t.

This boiler has been given an easy-to-use LCD touch screen display which leaves nothing to guesswork.

The icons are obvious, and information is displayed in clear English and numbers. 

Intelligent Auto Filling

The intelligent out filling is exactly what it sounds like. If you have ever had any boiler pressure issues before and had to look for a small fiddly tap to turn underneath your boiler then the Worcester 8000 negates ever having to do this again.

Instead, it monitors its own water pressure, and if the pressure drops, it automatically tops itself up to the required amount and continues to heat your home with no issues. 

Quiet In Operation

As much as the Greenstar 8000 is powerful, it’s also quiet in operation. This is excellent news if you consider having it on show in your kitchen or another living area.

At around 53 decibels, it isn’t the quietest boiler available from Worcester but taking the size of this boiler and everything into consideration.

They’ve done an excellent job keeping the operating noise level down. 

Easy remove front and access to main components

Worcester has ensured that everything about this boiler is hassle-free.

The front panel is easily removed, and all the installer or heating engineer components have been placed to be easily accessible. This ensures smooth servicing and easy fixing of any issues should they arise. 

High gloss finish or standard finish options

There are two different options for each type of boiler. There is the Life version and the Style version. The life version is the standard white boiler with a matt finish.

The style, on the other hand, offers you the option to have an impressive-looking unit that glistens and highly noticeable talking piece.

These gloss finishes are available in both black and white to suit your kitchen. 

Worcester Bosch 8000 System Boilers Review

The Worcester 8000 system boilers come with all the modern technology, the same as the combi boiler but are designed for larger homes or homes that already have a system boiler.

Worcester 8000 system boilers require a hot water tank to work and can deliver a lot of hot water to multiple taps at the same time.

Worcester 8000 Regular Boilers

Worcester has made a regular boiler in the 8000 range but only in the Life version.

There are no options to have the Style high gloss finish with the heat-only version. These boilers require both a hot water tank and a cold water tank to work.

The Worcester 8000 regular boiler is available in 5 different outputs, so if you require one of these fantastic replacement regular boilers then there are plenty of options to ensure that they have a boiler for your home. 

Worcester Bosch Greenstar 8000 Boilers Verdict

Worcester Bosch Greenstar 8000 boilers are clearly premium boilers with a hefty price tag, but let’s take a look at our verdict and see how they perform in each area, including the all-important value for money. 

Worcester 8000 performance review – 9/10

The Worcester 8000 is all about performance, and 9/10 does it justice.

You get a lot of boiler for your money, but we only really think this boiler is worth the extra price tag if you intend to have your boiler on show.

If you are hiding it away you can get more for your money with a cheaper boiler and not know any different. 

Worcester 8000 reliability review – 9/10

If you ever need to know how reliable a manufacturer thinks their boiler is, you can look at their stamp of approval, otherwise known as the warranty on offer.

Worcester has given this boiler a huge 12-year guarantee, so they are confident it is reliable and will continue for years to come. 

Worcester Greenstar 8000 Price review – 7.5/10

Unfortunately, given everything we have said in this review about how good this boiler is, we think the price tag is just a bit too on the big side for it to be value for money.

Taking into consideration you have to pay around £100 more for the high gloss finish then, unless you don’t care or want this boiler on the show then you can get a lot more boiler for your money.

The mid-range boiler in the Greenstar range, the Worcester 4000, is the perfect example. 

Worcester 8000 boiler warranty review – 9/10

Very few boiler companies offer more than 12 years of hassle-free heating.

The 12-year warranty that comes with this boiler should be expected as you will be paying a lot of money for this boiler, so you should get some peace of mind along the way.

12 years is good enough, and it is also a reliable boiler, so you should enjoy not having to do anything other than organise your Worcester boiler service every year.

Worcester Bosch Greenstar 8000 boilers review overall score 8/10

The Worcester Greenstar 8000 boiler range has loads going for it, but it also has a few things against it at the same time.

The price is a big issue.

It will be outside of many people’s price range, and the actual boiler is quite large, so if you don’t have space then you may struggle to fit this boiler in your home.

We strongly suggest you measure up first if you consider this boiler! 

Worcester Bosch 8000 Boiler Thermostats & Controls

Heating

Typically the Worcester 8000 is compatible with some of the best controls available such as Nest and Hive, but if you want to get the full Worcester experience, you may want to keep it in-house and get their own smart controls

Bosch EasyControl

The Bosch EasyControl smart thermostat is perfect for use with the Worcester 8000.

It even looks very similar to the boiler and comes in black and white to match your choice of boiler unit too. If you get the 8000, then this goes hand in hand and will look brilliant on your wall to match. 

Hive & Nest

If you like your current Nest or Hive smart thermostat then the 8000 is compatible with these too. You can simply connect these upon installation and continue to have your heating controls at your fingertips. 

Worcester 8000 boiler reviews summary – Compare Boilers & Save

The Worcester 8000 has been around for about two years now and has proved popular even though it costs considerably more than the average boiler.
