Worcester Bosch Greenstar 8000 Style System 30kW System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Style System 30kW boiler a combi, regular or a system boiler?

The Worcester Bosch Greenstar 8000 Style System 30kW is a system boiler you may wish to consider if you want this particular type of boiler for your house or flat.

System boilers need a hot water cylinder to work but, unlike heat only boilers, they don't require a cold water tank. This can be advantageous if you live in an apartment, lack attic space, or are planning a loft conversion.

System boilers allow you to set the times when you want hot water to be available. Heated water is stored in the cylinder and can be used throughout the day. With a system boiler, if you forget to set the timer, you will have to wait a while for hot water.

The constant supply of hot water from the cylinder ensures that you can have multiple taps and showers in use without a loss of pressure to each point (something combi boilers struggle with). This makes a system boiler suitable for large families and homes with more than one bathroom.

Should I choose a Worcester Bosch Greenstar 8000 Style System 30kW system boiler for my house or flat?

You should make sure that the boiler you choose for your property is the right "size". And size doesn't mean its physical dimensions. Size means how much power it has - the "output".

A boiler's output level measures how much power it can use to provide you with the hot water you need for your radiators and taps. If a boiler has a high output rate, it can heat greater volumes of water.

If you choose a boiler with too low an output, you'll find that the water coming out of your taps and in your radiators won't be as hot as you want it to be. Choosing one whose output is too high means you'll pay more than you need to for the gas your boiler needs to work.

The Worcester Bosch Greenstar 8000 Style System 30kW system outputs at a maximum of 30 kW, so which types of property would this Worcester Bosch Greenstar 8000 Style System 30kW System boiler be appropriate for?

A Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 8000 Style System 30kW System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Where will the Worcester Bosch Greenstar 8000 Style System 30kW fit in my house?

The Worcester Bosch Greenstar 8000 Style System 30kW is 825 mm tall, 440 mm wide, and TBC mm deep in size.

Is the Worcester Bosch Greenstar 8000 Style System 30kW a condensing or non-condensing boiler?

We recommend that you select a condensing boiler like the Worcester Bosch Greenstar 8000 Style System gas Worcester Bosch Greenstar 8000 Style System 30kW for your home if possible because of the environmental benefits and the money you'll save on your gas bills.

Condensing boilers are much more energy-efficient than older, non-condensing models as they capture and recycle the heat still present in the water vapour condensation and flue exhaust gases that your boiler creates when burning gas for reuse.

How energy efficient is the Worcester Bosch Greenstar 8000 Style System 30kW system boiler?

As more of us become concerned by the effects of climate change, the damage we do to the environment by heating our homes has emerged as an important issue for many homeowners.

The power we need for our central heating systems accounts for around 14% of the UK’s greenhouse gas production. There are often dangerous levels of ambient nitrogen dioxide gases in the atmospheres of British cities because of our use of gas boilers.

Would installing the Worcester Bosch Greenstar 8000 Style System 30kW system in your home be an environmentally friendly decision? Let's look closely at the figures.

All boilers manufactured after April 2018 in the UK must be rated as an “A” on the SEDBUK grading system, subject to a minimum energy efficiency rating of 92% or above. Before that, the minimum rate was 88% - boilers with an energy efficiency of 88% or 89% were given a “B” rating. Boilers scoring 90% or more were given an "A" rating.

The energy efficiency rating for a boiler describes the amount of energy it uses and how much goes to waste in operation.

The Worcester Bosch Greenstar 8000 Style System 30kW has an efficiency rating of 94% with a SEDBUK grade of "A".

The ERP (or Energy Related Products Directive) is European legislation which applies to all products that consume energy throughout their lifetime.

Worcester Bosch Greenstar 8000 Style System 30kW System Gas boiler frequently asked questions

What type of boiler is the Worcester Bosch Greenstar 8000 Style System 30kW?

If you are considering installing a system boiler in your house or flat, then the Worcester Bosch Greenstar 8000 Style System 30kW boiler is certainly worth investigating.

System boilers need a hot water cylinder to work, with the most popular installation location for cylinders being in an airing or landing cupboard. Unlike heat only boilers though, they don't require a separate cold water tank to go in the attic, making them suitable if roof space is at a premium or if you're planning a loft conversion in the future.

System boilers use (often built-in) circulating pumps to distribute hot water to your taps and radiators. Fitting is cheaper and quicker too because you don't need to find room for a water tank. Unlike with a combi boiler, which heats water it draws from the mains instantly, you have to program a system boiler with the times you want hot water and heating.

Is the Worcester Bosch Greenstar 8000 Style System 30kW system boiler the right choice for my house or apartment?

You should make sure that the boiler you install in your property is the right "size". And, by size, we don't mean how big it is, we mean how powerful it is - the "output".

Your boiler has to be powerful enough to heat all the hot water you need for your radiators and taps. Power is measured in kilowatts and the more kilowatts a boiler has available to it, the more water it can heat.

If the output (measured in kilowatts) is too high, you'll have all the power you need and more but your gas bills will be much higher. If it's too low, you'll often find that the water coming out of your taps and fed into your radiators is only lukewarm.

With the Worcester Bosch Greenstar 8000 Style System 30kW system's output at 30 kW, which types of property would this Worcester Bosch Greenstar 8000 Style System 30kW System boiler be most appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar 8000 Style System 30kW System boiler is appropriate for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Worcester Bosch Greenstar 8000 Style System 30kW size

The size of the Worcester Bosch Greenstar 8000 Style System 30kW boiler is 825 mm tall, 440 mm wide, and TBC mm deep.

Is the Worcester Bosch Greenstar 8000 Style System 30kW non-condensing or condensing?

The Worcester Bosch Greenstar 8000 Style System 30kW is a condensing gas boiler - we strongly suggest that you choose either this model or a recently released model if at all possible.

A condensing boiler captures and recycles the warmth present in flue exhaust gases and water vapour condensation created by the burning of gas to warm up the water coming back into your boiler - for example, from your radiators.

Condensing boilers cost less to run (lower gas bills) and are better for the environment.

Is the Worcester Bosch Greenstar 8000 Style System 30kW system environmentally friendly?

How we heat our homes is an issue which many homeowners worry about as the world combats climate change and environmental damage.

Dangerous levels of nitrogen dioxide emissions in larger UK cities are caused by gas boilers in domestic properties, and 14% of the UK’s greenhouse gas production is as a result of central heating.

Do the figures suggest that installing the Worcester Bosch Greenstar 8000 Style System 30kW system at your property would help in the fight against climate change?

All new British boilers must perform to a legal minimum energy efficiency of 92% (a low to good SEDBUK "A" rating). Prior to April 2018, the target was 88% (86-90% = SEDBUK "B" and 90%+ = SEDBUK "A").

Efficiency ratings are intended to let consumers know how much energy a boiler uses in its day-to-day activities and how much energy goes to waste.

The Worcester Bosch Greenstar 8000 Style System 30kW was awarded an efficiency rating of 94%, equivalent to a SEDBUK grade of "A".

The Energy Related Products Directive (ERP) was introduced in 2015 and applies to all products that consume energy throughout their lifetime, including during the manufacturing process and at the point of final disposal.

The purpose of the ERP is to ensure that companies create products that are kinder to the environment by reducing both the energy they use and the harmful emissions they produce.

The Worcester Bosch Greenstar 8000 Style System 30kW has an ERP rating of "A".

Is this Worcester Bosch Greenstar 8000 Style System 30kW system covered by a warranty?

A parts and labour warranty of 8 years is included when you purchase the Worcester Bosch Greenstar 8000 Style System 30kW boiler through PlumbProud.
