What is the Worcester Bosch 2000?

The Worcester Bosch 2000, which is also known now as the Worcester Bosch Greenstar 2000 boiler, is a combi boiler from one of the best brands in the business.

Worcester have a range of boilers available, including condensing gas boilers like the 2000, which can make it tricky for you to determine which boiler to get. The 2000 is a new model from this range, and the type is a gas combi boiler.

The Worcester 2000 is a wall-mounted boiler that can be installed directly to the water mains of your property and is designed to last years. It is available at an affordable price, which makes it a great option for new homeowners.

As it is a combi boiler, it can provide instant control of the central heating and hot water in your home. This is something that is highlighted frequently in reviews for this boiler, as it is of good use to everyone.

What Are The Best Features Of This Boiler?

For such an affordable boiler, the Worcester 2000 has some of the best features available.

These features include:

Two Types To Choose From

There are two options for the Worcester Bosch 2000, the 25kW model or the 30kW, both of which our installers can provide.

Both the 25kW and the 30kW versions of the Worcester Bosch 2000 are natural condensing combi boilers, but there are some things that you can compare. If you are struggling to decide which size of boiler you need, we can help you out!

The 25kW version of the boiler is suitable to use in small or medium homes that have one bathroom, with a good demand of hot water and heating, whereas the 30kW version of this boiler, according to reviews, is better to get if you have a larger home because of the water flow.

Both are available to get at the same affordable price.

Entry-Level Boiler

The Worcester Bosch 2000 is considered to be an 'entry level' boiler, making it ideal for people who have never had a Worcester boiler installed in their homes before. As it is entry level, the boiler is available at an affordable price, yet it still offers high levels of reliability and efficiency that we have come to expect from any Worcester boiler.

It can easily compare with some of the higher-end models from the brand in terms of quality and efficiency.

Quiet Operation

One of the best features of the Worcester Bosch 2000, as outlined by the brand and in customer reviews, is the fact it is a quiet boiler.

This is the case for both the 30Kw and the 25kW, which makes it a brilliant boiler option for the small to medium homes it is designed for.

Sleek, Modern Design

Likewise, the wall-mounted design of this gas boiler is intended to be sleek and won't stick out. This new design of gas boilers is inspired by other models from Worcester Bosch and makes them more versatile.

As it is wall mounted this combi boiler will save space in your kitchen or cupboard, and the modern design looks great in all settings, making it a good boiler to get regardless of the style of your home.

The Worcester Bosch 2000 range is designed to be installed in between kitchen cupboards with a compact size. Customer reviews guarantee that it will work in even the smallest kitchens.

Why Should You Get the Worcester Bosch 2000?

The Worcester Bosch 2000 is a great modern combi boiler that offers good control over the heating and hot water in your home.

It is an affordable option from the brand, making it suitable for new homeowners or those who have never had a Worcester boiler installed before.

As this specific model is a little cheaper than alternatives on the market, there are not as many controls or options on the Worcester Bosch 2000 such as the Worcester Bosch Greenstar 8000.

However, like the Worcester Bosch Greenstar 8000 boiler, the Worcester Bosch 2000 has a compact, modern design and is wall mounted, meaning it can be installed easily into almost any kitchen.

As we are going to explore in more detail throughout this review, this is an extremely energy efficient boiler. This means that if you choose to get the Worcester Bosch 2000, you will be saving money for years to come due to a reduction in energy bills.

Does the Worcester Bosch 2000 Come with a Warranty?

Like any other Worcester Bosch boiler, the Worcester Bosch 2000 comes with a warranty that offers several years of protection.

Specifically, this model is covered by a 7-year warranty on the primary heat exchanger, ensuring peace of mind for homeowners who install this boiler.

Even the most energy-efficient boilers start to wear out after 10 years, so you will want to look into getting your gas boiler replaced after a period of 10 to 12 years. With this in mind, the 7-year warranty offered by Worcester means that you will likely be protected for most of the boiler’s lifespan.

When considering the price of the boiler, it is important to look into how many years of warranty you can get for it to understand the total value of the product. The Worcester Bosch 2000, with its 7-year warranty, provides excellent protection and reliability.

Worcester Bosch 2000 Efficiency

Another key area to consider for a review, as well as the guarantee, is the energy efficiency of a boiler you want to get installed.

The Worcester Bosch Boiler 2000 is an A rate model for energy efficiency. It has a seasonal efficiency rating of 93% for both central heating and hot water that can help you save money over the years.

It has a flow rate of 12.3 litres per minute for the 30kW version of this boiler, which impacts the speed of water heating and is what will make it the best one to get for medium-sized homes. This is the same flow rate as the Worcester Bosch Greenstar i range of boilers, so you can get the same efficiency for a small fraction of the price with the Worcester 2000 gas combi.

In terms of the output rating of this compact size boiler, the 30kW is best to get for a medium home, according to reviews although both versions have the same energy efficiency rating.

As it is a compact size boiler, it can be used in a range of homes and almost anyone can get it, but the 30kW version of the Worcester Bosch 2000 is the best to get for a medium to large home due to the water flow rating and level of heating that it is designed for.

How Much Does the Worcester Bosch 2000 Cost?

Installing a new boiler into your home can be expensive, but the price tag on the Worcester 2000 is the main reason why it is so popular with customers.

This combi boiler offers an affordable way to get a Worcester Bosch boiler into your home. As it is a combi model, you can install it directly to your water mains making installation easy to get completed.

It comes with a guarantee for at least 10 years, and it is certain to continue running well for the entirety of these 10 years, making it an excellent investment.

If you are looking for a new boiler and heating system that will last years, then this entry level combi from Worcester Bosch is the best option out there. You can save money over the years and have instant access to heating and hot water, without worrying about high installation costs or bills which is something to consider when it comes to finding a new boiler for your home.

Worcester Bosch Boiler 2000 vs Worcester 8000

To help you save time and money when it comes to getting a new boiler, we couldn't complete this review without a comparison of two of Worcester Bosch's best boilers - the Worcester Bosch 2000 and its older brother the 8000.

There are some big differences that you will notice as soon as you compare the two, which is something many other reviews have done as well.

Compare Technology

The Worcester Bosch 8000 boiler is considered to be the most technologically advanced from the brand and is one of the most powerful.

In terms of energy and heat output, both of the boilers rely on similar energy, and both have an A-rating for efficiency. However, the 8000 boiler does have some better technical features such as the Intelligent Filling System, which maintains the pressure in the boiler and colour display.

Those using the 2000 boiler will see that they have fewer options in terms of controls, but they still have the intricate colour display that looks great and provides easy access to any adjustments.

iHeat New Boiler Cost

Boilers can be a daunting purchase for many people as they’re an appliance with a lot of responsibility, providing heat for you and your family is something you want to get right. Boilers aren’t exactly a quickly disposable item either, potentially lasting you a decade.

Effectively, new boiler cost can be split into two segments: the first is the actual boiler itself (unit price), and the second is the cost of the boiler being installed (set up) in your property by an expert engineer. 

Here at iHeat, we remove all of this undue stress and make the decision making process of upgrading to a new central heating system, as easy as possible.

New boiler costs can vary depending on a number of factors including their brand, model, fuel, output, warranty, labour and boiler installation type. Typically a new boiler will cost between £1,845 and £3,500, below is a list of average boiler installations offered by iHeat (guide only).
