Worcester Bosch brand overview

Worcester Bosch is a boiler brand that has become synonymous with reliability and performance, a brand regularly recognised by Which? Awards.

In the 2020 Boiler Brands report carried out by Which? Worcester Bosch scored brilliantly once again, being awarded Which? Best Buys across its entire Greenstar gas and oil boiler ranges. Worcester Bosch performed exceptionally for reliability and customer satisfaction.

Worcester has built an enviable reputation for customer aftercare, which is reflected in their 4.6/5 average score on Trustpilot. Customers are obviously happy with the product and the customer care they receive.

I have always acted according to the principle that I would rather lose money than trust. The integrity of my promises, the belief in the value of my products and in my given word have always had higher priority to me than a transitory profit.”

How many companies in modern society can say they hold themselves to the same principles Mr. Bosch did?

It wasn’t until 1992 that the Bosch Group joined forces with Worcester to become Worcester Bosch. Not many companies have such a rich history as that of the Bosch Group & Worcester.

In the 2020 Which? Best Buy annual Best Boiler Brand survey, Worcester Bosch received an overall score of 79%. Over 7,500 boiler owners and 153 boiler engineers from Which? Trusted Traders were asked to score Worcester Bosch boilers on:

• Reliability
• Customer Score
• Engineer recommendation
• Build quality
• Availability of parts and spares
• Ease of fixing a common fault
• Ease of servicing

Now that we know a bit about the background of Worcester Bosch, let’s see exactly what the Worcester Bosch 2000 Series of boilers delivers.

Worcester Bosch 2000 Key Specs

The Worcester Bosch 2000 series is ONLY available as a combi boiler, there are no system or regular versions of this boiler. It is designed to offer customers a more affordable version of the Worcester Bosch Life 8000 series by scaling down some of the features that not everyone will care about.

The 2000 series is also only available in a 25 & 30kW model, which is suitable for small and medium homes with one bathroom. If you have a large home with over 15 radiators or two bathrooms that will be used simultaneously, then the 2000 series probably won’t have the power you need for your system.

The Worcester Bosch 2000 series is the quietest boiler manufactured by Worcester Bosch with an ERP rating of 43dB, which is quiet for an appliance. So if the boiler is located in a living area such as the kitchen, then this is an excellent option.

The prices above are intended as guidelines only. Boiler prices are affected by location (if you go with a local tradesman) and what is included in the package. Be aware that if you buy a boiler without installation from a wholesaler, you will have more difficulty getting a heating engineer to fit it.

You generally get a better price by buying the boiler with installation packaged in. A WarmZilla boiler package includes the boiler, Gas Safe installation, wireless controls (remote control over your heating system), system filter (to stop nasties getting into your boiler), system cleanse (to flush your system before your new boiler goes in), any flues and extension kits you may require, and inhibitor, to coat the inside of your system to reduce rust.

What’s the difference between the 2000 and 8000 series?

There are a few differences between the Worcester Bosch 2000 Series and the 8000 Series, as you might expect, the cost is the main one, but there are a few others that we will cover in this section so you know exactly what kind of Bosch boiler you’re buying for your money.

Cost

Cost is probably the likeliest deciding factor between the 8000 series and the 2000 series. If money is no object, then get the Worcester Bosch 8000 Style, it offers better performance and some nifty little add-ons (which we’re about to cover).

However, for most of us, the cost is a major factor. So how much more does the 8000 cost than the 2000 Series?

Well, for a Worcester Bosch Greenstar 2000 25kW with a horizontal flue, the package price is £1,689 inc. VAT if you purchase through WarmZilla. The 8000 Series doesn’t offer a 25kW for a direct comparison but the price is bargainous, we think you’ll agree.

The Worcester 2000 Series 30kW with the same package costs £1,799 inc. VAT. The Worcester Bosch 8000 Life Series 30kW costs £2,499 inc. VAT. £700 more than the 2000 series, a decent wedge. Even if purchased on boiler finance that’s still a substantial increase.

It’s worth mentioning here that the 2000 Series comes with a 5-year guarantee and the 8000 Series comes with a 10-year guarantee with WarmZilla, so you also get an added five years peace of mind on the 8000 series.

WarmZilla offers a Best Price Guarantee on our boiler prices because we’re sure our prices can’t be beaten. If you find a cheaper price on a new boiler elsewhere, we’ll beat the price by £50.

Gadgets

If you’re anything like us, you love a gadget (the shinier the better). Even when it comes to your boiler, you want all the bells and whistles. It will come as no surprise that the 8000 series trumps the 2000 Series when it comes to gadgetry. But is it worth the extra £700?

Firstly, the 8000 series comes with an intelligent filling system, which keeps your boiler pressure topped up and maintained at all times. A pretty nice feature, nobody wants the hassle of having to repressurise their boiler.

The Life/Style boilers in the 8000 range also have fancy LCD screens, with the Style offering a full-colour touchscreen display. Very schmancy indeed.

The 8000 series is also compatible with a wider range of smart controls than the 2000 Series, so if you like your gadgets then you may want to opt for the 8000 Series.

The 2000 series is actually quieter in operation than the 8000 series so it does win that round but as you would expect, the 8000 Series does offer a fair bit more in terms of gadgets.

Performance

The Worcester Bosch 8000 will outperform the 2000 series in terms of efficiency rating, central heating output, and flow rate, but by how much?

As we can see from the table above, the Life 30kW performs significantly better than the 2000 Series in terms of performance. It offers higher central heating output, meaning it is faster and more efficient at heating your home. It will heat your radiators faster, so your home will be warmer without having to wait as long.

The 8000 Series also offers a higher flow rate, which means that it can heat hot water faster than the 2000 series can. One thing to note here is that if you only have 10 litres of water flowing into your property per minute then it won’t matter that the 8000 Life has a flow rate of 12.3 litres per minute.

You can also see that the 2000 Life is significantly quieter than the 8000 series, it’s actually one of the quietest boilers on the market.

2000 v 8000 Conclusion

Whilst the 8000 Series (Life model) is £700 more expensive based on a direct 30kW comparison, you do actually get a fair bit more performance for your money.

So what it comes down to is how much spare money, if any, you have that you want to spend on having the highest spec boiler? The 2000 series is a great entry-level boiler, priced to compete with mid-range boilers while giving you the reliability and aftercare that Worcester is famous for – the Worcester Bosch Greenstar 2000 offers exceptional value for money.

If you can afford the 8000 series, we recommend it, if you can’t, then the 2000 series offers a great boiler at a really low price for a Worcester.

What’s the difference between the 2000 and 4000 series?

Worcester Bosch is releasing the newest member to the Greenstar range on May 17th, 2021. It’s a little too soon to talk about performance yet, however, this blog will be updated as more information is released. In the meantime, let’s compare the Worcester Bosch 2000 and the information we have on the brand new Greenstar 4000.

Available as both a combi boiler and a system boiler, this brand new boiler is the big brother to the Greenstar i range.

Based on the design of the famous, best-selling boiler on the market, the Worcester Bosch Greenstar i, Worcester Bosch have created a new and improved version, raising the bar with ease and speed of installation, commissioning and servicing. The exterior of the 4000 series is very similar to that of the Worcester Bosch 8000 LifeStyle boiler, but we anticipate it will be significantly cheaper.

This means you are getting all the great features and benefits of the Worcester Bosch Greenstar i, but with a little added spice.

The Worcester Bosch 4000 will be available as a combi boiler with outputs of 25kW and 30kW available with a flow rate of up to 12.3 l/min, and a system boiler in 12kW, 15kW, 18kW, 21kW and 24kW.

Worcester Bosch has designed the 4000 series as a ‘SimpleSwitch’ for customers who have an existing Greenstar i, i Junior or Si boiler, as the brand new Greenstar 4000 physically fits within the i footprint of these boiler ranges.

Worcester Bosch claims that the brand new Greenstar 4000 will have a quieter operation and increased hot water efficiency compared to their Greenstar i range. The Greenstar 4000 has frontal access to all key components for easy installation and any future servicing or maintenance.

The Worcester Bosch Greenstar 4000 has been designed to be compact and lightweight, meaning that it can be fitted neatly inside your standard kitchen cupboard, out of sight, out of mind.

Information Table

Now that we have some key information about the newest member of the Greenstar family, let’s compare the Worcester Bosch 2000 and 4000 based on the information we have available to see which is the better option for your home.

As you can see from the comparison table, there are a few differences between the Worcester Bosch 2000 and the new Worcester Bosch Greenstar 4000. The first being flow rate. The Greenstar 4000 offers a higher flow rate of 12.3 litres a minute, meaning that the quality of your showers will be better.

The next is the guarantee. The Greenstar 4000 has an extra 2 years standard guarantee for added peace of mind. However, Worcester Bosch Exceletate members can get up to 10 years guarantee if fitted with a Worcester Bosch Installer.

The final difference is size. Now, I know we all say size doesn’t matter, but, when it comes to boilers, it does. The Worcester Bosch 4000 is slightly smaller in height compared to the Worcester Bosch 2000, however, both have been designed to fit neatly inside a standard kitchen cupboard.

It looks like the Worcester Bosch Greenstar 4000 is going to be a winner, however, as mentioned, more information will follow about the 4000’s performance and energy efficiency.

Similar boilers from other brands to the 2000 series?

There are quite a few entry-level boilers that would look to compete with the Worcester Bosch Greenstar 2000 Series.

We’ll be comparing the Baxi Duo-tec Combi 24 Gas Boiler, the Ideal Vogue Max C26 Combi Gas Boiler, and the Vaillant ecoFIT pure 825 Combi Gas Boiler. They all offer roughly the same output (around the 30kW range) and are roughly the same price bracket.

We can see that in all the key areas the Worcester Bosch Series 2000 boiler outperforms the competition. It goes toe-to-toe with the competition on Central Heating Output, just losing out to the Baxi Duo-tec by a humble kW.

It offers a solid 30kW for hot water output, comfortably easing ahead of the competition. The 2000 also edges the competition out on flow rate too.

A solid performance all-round, the only area the Worcester Bosch 2000 loses out is on the warranty section. It only offers 5 years compared to the 10 years on Ideal, the Ideal is a warranty and not a guarantee, so while the Worcester maybe half the term it’s double the protection. The others only offer a 2-year warranty so the Worcester Bosch has them beaten there.

The Worcester Bosch is the cheapest of the selection and it offers better performance on the whole. The 2000 series from Worcester Bosch really is a solid option at the lower to mid-range boiler price.

WarmZilla sells Worcester Bosch, Ideal, and Vaillant boilers at the time of writing. We aren’t biased toward any particular boiler brand other than which one can offer our customers the best value for money on their new boiler.

Worcester Bosch ticks all the boxes for product quality, performance, and aftercare. Normally, their boilers are a little more expensive than the other models but in the case of the 2000 Series, they’ve combined value-for-money with the Worcester brand reputation and the result is a win for the consumer.
