Worcester Bosch Greenstar 8000 Life System 35kW System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Life System 35kW a regular, combi or system boiler?

If you are considering installing a system boiler in your house or flat, then the Worcester Bosch Greenstar 8000 Life System 35kW boiler is certainly worth investigating.

System boilers, like regular boilers, require a hot water cylinder (usually placed in a landing or airing cupboard) to work but they don’t require a separate cold water tank. This makes installation quicker and easier and, for homeowners with little loft space or who are considering a loft conversion, they're a more suitable choice.

System boilers don't need separate water tanks because they contain built-in circulating pumps that perform the same task. Just like heat only boilers, they require you to program in the times when you want heating and hot water to be available - they don't offer instant hot water like combi boilers. The cylinders keep whatever water they contain warm, although, if there is no hot water in the tank, you will have to wait up to an hour before hot water will come through your taps.

Would the Worcester Bosch Greenstar 8000 Life System 35kW system be a suitable choice of boiler for my house or flat?

To determine that, we need to consider the size of the boiler. Size doesn't mean how big it is - it means how big its "output" is.

The output rate of a boiler tells you how much power it has available to it for heating the water that comes out of your taps and warms your radiators. A higher output rate means that your boiler has more power at its disposal.

You need to make sure you select a boiler with the right output rate. That's because, if your output rate is too high, then your boiler will have more power than it needs but it will cost too much to run. If the output rate is too low, your water may often not be hot enough.

The Worcester Bosch Greenstar 8000 Life System 35kW system's output is 35 kW, so which types of property would this Worcester Bosch Greenstar 8000 Life System 35kW System boiler be appropriate for?

Most Gas Safe boiler installers would recommend that a boiler with this output level would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


What is the size of the Worcester Bosch Greenstar 8000 Life System 35kW?

The Worcester Bosch Greenstar 8000 Life System 35kW measures 780 mm in height and has a width of 440 mm and a depth of 365 mm.

Greenstar 8000 Life System 35kW – non-condensing or condensing?

The Worcester Bosch Greenstar 8000 Life System 35kW is a condensing gas boiler - we’d strongly recommend that you choose the very latest condensing model for your home.

Condensing boilers run on either gas or oil and are manufactured specifically to improve energy efficiency. They do this by capturing and recycling the warmth present in flue exhaust gases and water vapour condensation into more usable heat the system can use, meaning they're far more efficient and cost less to run.

Is the Worcester Bosch Greenstar 8000 Life System 35kW system boiler environmentally friendly?

How we heat our homes and the damage we might be doing to the environment as a result has become an important point of concern to many homeowners worried about climate change.

Gas boilers are responsible for dangerous atmospheric levels of nitrogen dioxide emissions in Britain's biggest cities and, overall, 14% of the UK’s greenhouse gases are produced by our domestic central heating systems.

Will choosing a Worcester Bosch Greenstar 8000 Life System 35kW system boiler for your home be positive for the environment? Let's examine the figures.

An energy efficiency rating of 92% or above is a legal requirement for all boilers manufactured and installed in the UK today. 92% is equivalent to a low-to-middle "A" grade on the "Seasonal Efficiency of Domestic Boilers" (SEDBUK) scale.

Energy efficiency measures how much energy a boiler uses and wastes in the course of its normal operation. The lower the waste, the lower your gas bills.

The Worcester Bosch Greenstar 8000 Life System 35kW was awarded an efficiency rating of "94%", equivalent to a "A" rating on the SEDBUK system.

The Energy Related Products (ERP) directive is Europe-wide legislation designed to reduce harmful gas emissions at all points of a product's life cycle - from the production process to its actual end use right through to final disposal.

The Worcester Bosch Greenstar 8000 Life System 35kW has a rating of "A".

What is the length of the warranty on the Worcester Bosch Greenstar 8000 Life System 35kW?

You receive a parts and labour warranty of 8 years with the Worcester Bosch Greenstar 8000 Life System 35kW boiler.

Worcester Bosch Greenstar 8000 Life System 35kW System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar 8000 Life System 35kW boiler a combi, regular or a system boiler?

The Worcester Bosch Greenstar 8000 Life System 35kW boiler is a system boiler you may wish to consider when looking for a new boiler for your house or flat.

System boilers need a hot water cylinder to work, which is normally situated in an airing cupboard or similar. However, unlike heat only boilers, system boilers don’t require a separate cold water tank, meaning they are a preferred option for some homeowners, especially those planning a loft conversion in the future.

They use (often built-in) circulating pumps to distribute hot water to your taps and radiators and installation is often easier from scratch with heat only boilers as there’s one less component (the water tank) to purchase and fit.

System boilers also need programming for heat and hot water and don’t offer this instantly. However, the cylinder can keep water hot for use afterwards so you shouldn’t have to wait around for your bath water so long as you set your timer and have it on long enough to heat the water you’ll need for the day.

Is a Worcester Bosch Greenstar 8000 Life System 35kW system boiler suitable for my house or apartment?

Whether this Worcester Bosch Greenstar 8000 Life System 35kW 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.

The output level of a boiler tells you how much power it has to heat the water coming from your taps and warming up your radiators. The higher the output level, the greater the volume of water it can heat up.

If the output (measured in kilowatts) is too high, you'll pay higher gas bills and your water will be piping hot. Too low and the water coming out of your taps and being fed into your radiators will often be lukewarm.

The Worcester Bosch Greenstar 8000 Life System 35kW system outputs at a maximum of 35 kW, so which types of property would this Worcester Bosch Greenstar 8000 Life System 35kW System boiler be appropriate for?

A PlumbProud Gas Safe boiler installer would recommend that the most suitable type of property for this Worcester Bosch Greenstar 8000 Life System 35kW System boiler would be larger properties including detached homes containing 15 or more radiators and two or more bathrooms.


The size of the Worcester Bosch Greenstar 8000 Life System 35kW in millimetres

The Worcester Bosch Greenstar 8000 Life System 35kW occupies a space of 780 mm high by 440 mm wide and 365 mm deep.

Is the Worcester Bosch Greenstar 8000 Life System 35kW non-condensing or condensing?

We strongly recommend that you choose a condensing boiler like the Worcester Bosch Greenstar 8000 Life System 35kW - the technology is improving every year so the newer the boiler, the better.

A condensing boiler captures and recycles the warmth still present in flue exhaust gases and water vapour condensation into heat, allowing it to perform more efficiently on tasks like heating the colder water returning from your radiators.

They also offer significant annual savings on household gas bills as well as being more environmentally friendly.

How does the Worcester Bosch Greenstar 8000 Life System 35kW system rate environmentally?

How we heat our homes has become a pressing issue of concern for many homeowners worried about climate change and the environmental impact of their personal choices.

About 14% of the greenhouse gases we produce in the UK come from the power needed for central heating. In bigger British cities, gas boilers are a significant source of nitrogen dioxide emissions.

Would installing a Worcester Bosch Greenstar 8000 Life System 35kW system boiler in your home be a green choice? Let's look at the numbers.

Every boiler manufactured and supplied in the UK must have an energy efficiency rating of 92% (SEDBUK “A” rating). These minimums were made law in April 2018 - before that, the minimum energy efficiency rating was 88% (88%/89% = "B" SEDBUK grade, 90%+ = "A" SEDBUK grade).

The Worcester Bosch Greenstar 8000 Life System 35kW was awarded an efficiency rating of 94% and a band rating of "A".

Energy efficiency ratings for boilers describe the amount of energy they use and waste when switched on and working.

The ERP (Energy Related Products Directive) is European legislation that aims to reduce the use of energy at all points during a product's life, from the point of manufacture to when it's in active use right through to final disposal.

The regulation aims to encourage manufacturers to create products that are more environmentally friendly and which reduce gas emissions associated with those products.

The ERP grading for the Worcester Bosch Greenstar 8000 Life System 35kW is "A".

Does the Worcester Bosch Greenstar 8000 Life System 35kW system boiler come with a warranty?
