Worcester Bosch Greenstar i System 30i System Gas boiler frequently asked questions

Worcester Bosch Greenstar I System 30i - a system boiler, regular boiler or combi boiler?

Looking for a gas system boiler for your flat or house? Then the Worcester Bosch Greenstar I System 30i may be an option you should consider.

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.

Is a Worcester Bosch Greenstar I System 30i system boiler suitable for my house or apartment?

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 30i system has an output of 30 kW, so which types of property would this Worcester Bosch Greenstar i System 30i System boiler be appropriate for?

A heating engineer would recommend that this Worcester Bosch Greenstar i System 30i System boiler would provide adequate heating and hot water for larger properties including detached homes with up to 15 or more radiators and two or more bathrooms.


What size is the Worcester Bosch Greenstar I System 30i boiler?

The Worcester Bosch Greenstar I System 30i is 690 mm high by 390 mm wide by 280 mm deep.

Is the Worcester Bosch Greenstar I System 30i a non-condensing or condensing boiler?

Condensing gas boilers like the Worcester Bosch Greenstar I System 30i are more energy-efficient and choosing one for your home will cut the amount you pay every year for your gas.

They do this by capturing the heat in water vapour condensation and in exhaust gases which would normally be expelled via the flue. They then recycle that heat, returning it to the system to, among other tasks, reheat colder water that is returning to your boiler from your radiators.

Is the Worcester Bosch Greenstar I System 30i system boiler environmentally friendly?

Environmentally-friendly heating has become an important issue for homeowners concerned about the accelerating pace of climate change.

14% of the total amount of greenhouse gases produced by the UK comes from the central heating systems we use. In some of Britain's biggest cities, gas boilers create dangerous levels of nitrogen dioxide in the atmosphere.

Will choosing a Worcester Bosch Greenstar I System 30i system boiler for your home be positive for the environment? Let's examine the figures.

Boilers manufactured and installed in the UK are assigned energy efficiency ratings following testing to an agreed set of standards. These scores indicate how much energy the boiler uses and how much goes to waste when it's in operation.

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 I System 30i was awarded an efficiency rating of 92% with a SEDBUK band rating of "A".

The Energy Related Products Directive, also known as ERP, is European legislation that intends to reduce energy consumption related to products right from their initial manufacturing process through to eventual final disposal.

The purpose of the directive is to encourage manufacturers to create new products that are kinder to the environment and which result in lower overall harmful gas emissions through a product's entire life cycle.

The Worcester Bosch Greenstar I System 30i has a rating of "A".

Am I covered if my Worcester Bosch Greenstar I System 30i system boiler breaks down?

The Worcester Bosch Greenstar I System 30i boiler is provided with a parts and labour warranty lasting 7 years.

Worcester Bosch Greenstar i System 30i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 30i a combi, system or regular boiler?

Worcester Bosch’s Greenstar I System 30i is one you might consider if you’re looking for a system boiler for your house or flat.

Ever since system boilers arrived on the market, they have been a popular choice in new homes. In the same way as regular boilers, they work along with a hot water cylinder, which is usually located in an airing cupboard. Since system boilers do not require a separate cold water tank, they appeal to some homeowners, especially if they intend to convert their loft in the future.

Their design includes (often built-in) circulating pumps to send hot water to your taps and radiators. They're also quicker and easier to install because you don't need to find room for and fit a water storage tank.

In addition, system boilers require programming for the flow of heat and hot water, which is not available right away. In any case, the cylinder keeps the water hot for use later, so you shouldn't have to wait for your bath as long as you set your timer and leave it on for long enough to heat sufficient water to use throughout the day.

Is a Worcester Bosch Greenstar I System 30i system boiler suitable for my house or flat?

It's best to choose a boiler whose size or "output" is right for your home.

The more hot water and heat you want, the higher the output level of your boiler should be. Output is measured in kilowatts and it describes the maximum level of power your boiler has to heat water.

If your output level is too low, your boiler will not have the power it needs to get your water as hot as you want it, particularly when there's a lot of demand for it. Choose a boiler whose output level is too high and you'll have all the hot water you need but will be paying too much for it through higher gas bills.

Which types of property would this Worcester Bosch Greenstar i System 30i System boiler be appropriate for given its output of 30 kW?

A PlumbProud Gas Safe boiler installer would recommend that the most suitable type of property for this Worcester Bosch Greenstar i System 30i System boiler would be larger properties including detached homes containing 15 or more radiators and two or more bathrooms.


Making space for the Worcester Bosch Greenstar I System 30i

The size of the Worcester Bosch Greenstar I System 30i boiler is 690 mm tall, 390 mm wide, and 280 mm deep.

Is the Worcester Bosch Greenstar I System 30i condensing or non-condensing?

Condensing gas boilers like the Worcester Bosch Greenstar I System 30i 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 choosing the Worcester Bosch Greenstar I System 30i system boiler environmentally friendly?

The effects of climate change on the environment are leading many homeowners to question the damage they might be doing by the way they heat their homes.

We generate 14% of UK greenhouse gas emissions through centrally heating our domestic properties. Gas boilers are mainly responsible for harmful nitrogen dioxide emissions in larger British cities.

Will choosing to install a Worcester Bosch Greenstar I System 30i system in your home help the environment? Let's review the figures.

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 I System 30i was awarded an efficiency rating of 92% 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 Energy Related Products Directive intends to encourage all manufacturers to reduce harmful gas emissions connected to the products they make, from the manufacturing stage to final disposal, including when they are in active use.

The Worcester Bosch Greenstar I System 30i has an ERP rating of "A".

What is the warranty period for the Worcester Bosch Greenstar I System 30i?

The Worcester Bosch Greenstar I System 30i boiler is covered by a parts and labour warranty of 7 years.
