Worcester Bosch Greenstar 4000 24kW System Gas boiler frequently asked questions

What type of boiler is Worcester Bosch’s Greenstar 4000 24kW - system, regular or combi?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar 4000 24kW.

Like heat only boilers, system boilers need a hot water cylinder to work - they're normally installed inside an airing or landing cupboard. However, since system boilers do not require a separate cold water tank, they are popular with homeowners who are planning to convert their loft or where attic space is already at a premium.

They're able to distribute the hot water you need to taps and radiators through (often built-in) circulating pumps and, because there's no water tank to install, they're easier, quicker and cheaper to install than heat only boilers. To get the heat and hot water you need when you need it, just use the control panel to program the times and days you want.

Should I install a Worcester Bosch Greenstar 4000 24kW system boiler in my house or flat?

Whether this Worcester Bosch Greenstar 4000 24kW System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions - it means how powerful it is.

A boiler’s output is a measurement of the amount of power it can use to provide hot water to your taps and radiators. The higher its output rate, the more water it can heat.

If your new boiler’s output is too low, your hot water might not be as hot as you want it to be. If it's too high, you’ll be paying more for gas than you need to.

The output of the Worcester Bosch Greenstar 4000 24kW system boiler is 24 kW, so which types of property would this be appropriate for?

To most boiler engineers, the Worcester Bosch Greenstar 4000 24kW system Greenstar 4000 would be most suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.


How big is the Worcester Bosch Greenstar 4000 24kW?

The dimensions of the Worcester Bosch Greenstar 4000 24kW are 724 mm tall, 400 mm wide, and 310 mm deep.

Is this Worcester Bosch boiler condensing or non-condensing?

Is the Worcester Bosch Greenstar 4000 24kW system considered environmentally friendly?

With more and more of us concerned about environmental issues and climate change, how we heat our homes has become an important issue to many homeowners.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Let's take a closer look at whether installing a Worcester Bosch Greenstar 4000 24kW system would be a good choice for the environment.

All boilers manufactured and installed in the UK are required to have an energy efficiency rating of 92% or above (or a good “A” SEDBUK rating). Before April 2018, when the law changed, the minimum energy efficiency level permissible was 88% (86-90% is a SEDBUK "B" rating and 90%+ is an "A" rating).

A boiler's energy efficiency rating indicates the amount of energy used and wasted during normal operational performance.

Following its assessment, the Worcester Bosch Greenstar 4000 24kW was given an efficiency rating of 94% and a SEDBUK grading of "A".

Energy-efficient boilers help the environment as they require less fuel and emit fewer harmful gases. In 2015, the EU introduced the Energy Related Products Directive (ERP) with the aim of ensuring that all manufacturers, including boiler manufacturers, developed more efficient products and processes.

This legislation aims to conserve energy at all life cycle stages, from initial production through to actual use by a customer and up to the point of disposal.

The Worcester Bosch Greenstar 4000 24kW has been given an ERP rating of "A".

How many years' warranty does the Worcester Bosch Greenstar 4000 24kW system come with?

A parts and labour warranty of 7 years is included with the Worcester Bosch Worcester Bosch Greenstar 4000 24kW boiler.

Worcester Bosch Greenstar 4000 24kW System Gas boiler frequently asked questions

Worcester Bosch Greenstar 4000 24kW - a regular boiler, combi boiler or system boiler?

You might want to consider the Worcester Bosch Greenstar 4000 24kW for your house or flat if you are looking for a system boiler.

System boilers are suitable for homes with a higher-than-average demand for central heating and water - for example, larger homes and larger families.

Tell the boiler when you want hot water using the control panel - it draws water from the mains, heats it and keeps it warm throughout the day in the hot water cylinder. As long as you remember to tell the boiler when you want hot water, you have a big enough cylinder, and there's not an unusually high demand for water on a particular day, you should have hot water whenever you need it.

System boilers do not require a cold water storage tank either, unlike heat only boilers, meaning they're cheaper, quicker and easier to install.

Is a Worcester Bosch Greenstar 4000 24kW system the right boiler for my house or flat?

Whether this Worcester Bosch Greenstar 4000 24kW System boiler is right for your property depends on its size or what its "output" level is. Size does not mean its physical dimensions, however - it means how powerful it is.

The output rating indicates how much energy a boiler can use in providing you with hot water and heat when you need it from your radiators and taps. The greater the output, the more water it can heat.

It's better to take advice on this from a registered installer because, if your boiler output is too low, your water and radiators might not get as hot as you would like them to be. However, if the output level is too high, you'll end up paying more on your gas bills than you need to.

Which types of property would this Worcester Bosch Greenstar 4000 24kW System boiler be appropriate for given its output of 24 kW?

An experienced PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 4000 24kW System boiler is suitable for medium-sized homes and larger apartments with 10-15 radiators and two bathrooms.

How does the Worcester Bosch Greenstar 4000 24kW system boiler rate environmentally?

How we heat our homes and the effect that has on climate change has become important to many homeowners worried about the environment.

By law, boilers must achieve a SEDBUK rating of "A" subject to achieving a minimum of 92% energy efficiency. Prior to April 2018, the minimum was 88% (88% and 89% on the SEDBUK are graded "B" and 90% and above is graded "A").

The Worcester Bosch Greenstar 4000 24kW was awarded an efficiency rating of 94% with a SEDBUK band rating of "A".

In 2015, the Energy Related Products Directive (ERP) came into force. The legislation applies to all products that consume energy - in production, during their active life, and at the point of final disposal.

The ERP was introduced to incentivise manufacturers to create products that emit fewer harmful gases with the larger aim of protecting the wider environment.

The Worcester Bosch Greenstar 4000 24kW has been awarded an ERP rating of "A".
