Worcester Bosch Greenstar i System 27i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 27i boiler a standard, combi or system model?

Looking for a gas system boiler for your flat or house? Then the Worcester Bosch Greenstar I System 27i may be an option you should consider.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

System boilers distribute the hot water to your taps and radiators using (often built-in) circulation pumps and are easier to install from scratch since they have one less component (the water tank) to consider.

System boilers also require programming to produce heat and hot water, so they cannot produce this instantly. Nonetheless, the cylinder keeps water hot for use later, so you don't have to wait as long as you set your timer and keep it on long enough to heat enough water.

Is a Worcester Bosch Greenstar I System 27i system a suitable choice for my house or flat?

Whether this Worcester Bosch Greenstar i System 27i System boiler is right for where you live depends on its size or "output" level. Size does not mean its physical dimensions, however - it means how powerful it is.

Measured in kilowatts, a boiler's output level is an indication of the amount of power it has available to it to heat the water coming from your taps and for warming your radiators. The greater the output level, the more water it can heat.

If you choose a boiler whose output level is too low, you'll often find that the water is not as hot as you want it to be. If you choose a boiler whose level is too high, you'll be paying higher gas bills than you need to for years to come.

The output of the Worcester Bosch Greenstar I System 27i system is 27 kW, so which types of property is this Worcester Bosch Greenstar i System 27i System boiler appropriate for?

A Gas Safe boiler installer would recommend that this Worcester Bosch Greenstar i System 27i System boiler would be a suitable choice for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


Making space for the Worcester Bosch Greenstar I System 27i

The Worcester Bosch Greenstar I System 27i is 690 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar I System 27i a non-condensing or condensing boiler?

The Worcester Bosch Greenstar I System 27i is a condensing gas boiler - in fact, we recommend that you select this model or one of the latest condensing boilers on the market as the technology continues to improve over time.

Condensing boilers capture the heat still present in the flue exhaust gases and water vapour condensation created when the gas is burned and they recycle this back into the heating system to warm up the cold water re-entering the boiler from your radiators.

They're much more environmentally friendly and installing one results in much lower annual gas bills.

Is the Worcester Bosch Greenstar I System 27i system environmentally friendly?

As the British public has become more conscious of climate change, many homeowners consider the environment when choosing how to heat their homes.

Nitrogen dioxide emissions in Britain's largest cities are at dangerous levels and this has been caused by gas boilers. In fact, 14% of the UK’s greenhouse gases are produced by central heating.

Do the available figures suggest that installing the Worcester Bosch Greenstar I System 27i system in your property would be an environmentally friendly choice?

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 I System 27i was awarded an efficiency rating of 92%, equivalent to a SEDBUK grade of "A".

In 2015, new legislation was introduced by the EU to encourage manufacturers to develop more energy-efficient products that emit fewer harmful gases throughout their lifetime.

The Energy Related Products Directive (ERP) applies to all products that consume energy, including during the manufacturing process, at the point of final disposal, and all points in between.

The ERP rating of the Worcester Bosch Greenstar I System 27i is "A".

What warranty do I get if I purchase the Worcester Bosch Greenstar I System 27i boiler?

A parts and labour warranty of 7 years is included when you purchase the Worcester Bosch Greenstar I System 27i boiler through PlumbProud.

Worcester Bosch Greenstar i System 27i System Gas boiler frequently asked questions

Which category of boiler does the Worcester Bosch Greenstar I System 27i fit into?

Looking for a gas system boiler for your house or flat? If you are, the Worcester Bosch Greenstar I System 27i boiler may be worth considering.

If you choose a system boiler, you'll have to find somewhere to install a hot water cylinder too - they're normally located in an airing or landing cupboard. However, unlike regular boilers, they do not require a cold water tank to be fitted in the attic, making them suitable for homes with limited or no roof space or if you're planning a loft conversion in the future.

Is a Worcester Bosch Greenstar I System 27i system a suitable choice for my house or flat?

Selecting the right boiler for your home means choosing a boiler that 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’s output is a measurement of the power it has available to it to heat the water you need for your radiators or for when you turn on a tap, bath or shower. A higher output rate means it has more power and can heat more water.

It's important to choose an output that matches the demand for water in your home because if your boiler has too low an output, you'll often find only lukewarm water comes out of your taps or heats your radiators. If it’s too high, you’ll be paying more for your gas than you need to.

The Worcester Bosch Greenstar I System 27i system has an output of 27 kW, so which types of property would this Worcester Bosch Greenstar i System 27i System boiler be appropriate for?

An experienced PlumbProud Gas Safe boiler installer would almost certainly recommend that this Worcester Bosch Greenstar i System 27i System boiler would be most suitable for larger properties including detached homes with 15 or more radiators and two or more bathrooms.


How large is a Worcester Bosch Greenstar I System 27i boiler?

The Worcester Bosch Greenstar I System 27i measures 690 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar I System 27i a condensing or non-condensing boiler?

Condensing gas boilers like the Worcester Bosch Greenstar I System 27i are environmentally friendlier and cheaper to run so, if possible, we strongly recommend that you choose this or one of the very latest models.

Condensing boilers are much more efficient and economical to run because they contain a secondary heat exchanger that captures and recycles the warmth still present in the flue exhaust gases and the water vapour condensation for re-use, meaning that they use less gas to run.

Is the Worcester Bosch Greenstar I System 27i system a good choice for the environment?

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

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 choosing a Worcester Bosch Greenstar I System 27i system help the environment? Let’s see what the performance figures suggest.

In the UK, by law, all boilers manufactured since April 2018 must have a SEDBUK “A” rating and operate to a minimum level of 92% energy efficiency. Prior to this, the minimum was 88% – 88/89% would score a "B" and 90% or more an "A" on the SEDBUK scale.

The energy efficiency rating measures the amount of energy a boiler consumes when it's in use and how much it loses on non-core operations.

Following testing, the Worcester Bosch Greenstar I System 27i was given an efficiency rating of 92% and a SEDBUK grading of "A".

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 I System 27i is "A".

If the Worcester Bosch Greenstar I System 27i system boiler breaks down, am I covered?

Parts and labour charges incurred for repairs made to your new Worcester Bosch Greenstar I System 27i are covered by a 7 year warranty.
