Worcester Bosch Greenstar i System 15i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 15i a regular, combi or system boiler?

If you’re looking for a system boiler for your house or flat, then the Worcester Bosch Greenstar I System 15i is one you may wish to consider.

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 I System 15i system boiler suitable for my house or apartment?

It's best to choose a boiler whose size or "output" is right for your property. With boilers, however, size does not mean how big a boiler is, it means how much power it has.

A boiler’s output indicates the amount of power it can use when heating the water which it then sends to your taps and radiators. The higher the output rate, the more water it can heat.

If a boiler’s output is too low, there will be times when your hot water might not be as hot as you want it to be. If it is too high, you’ll likely be paying more than you need to for your gas.

Measured in kilowatts, the Worcester Bosch Greenstar I System 15i system's output level is 15 kW, so which types of property would this Worcester Bosch Greenstar i System 15i System boiler be an appropriate choice for?

An experienced boiler engineer would recommend that this Worcester Bosch Greenstar i System 15i System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


Worcester Bosch Greenstar I System 15i dimensions

The Worcester Bosch Greenstar I System 15i has the following dimensions - 710 mm high, 400 mm wide, and 330 mm deep.

Is the Worcester Bosch Greenstar I System 15i non-condensing or condensing?

The Worcester Bosch Greenstar I System 15i 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 I System 15i system an environmentally friendly boiler?

With so many of us worried about the environmental impact of our personal choices, the relationship between how we heat our homes and climate change has become an important issue for many homeowners.

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.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar I System 15i system in your home? Let’s look at the figures.

The energy efficiency rating for a boiler describes the amount of energy it uses and wastes during operation and there are two different ways to measure it.

All boilers manufactured and supplied in the UK must have a SEDBUK rating of “A” subject to a minimum energy efficiency score of 92% or above. Before April 2018, the minimum energy efficiency score was 88% (88/89% = "B" SEDBUK rating, 90%+ = "A" SEDBUK rating).

The Worcester Bosch Greenstar I System 15i scored an efficiency rating of 94% and a SEDBUK band rating of A.

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

The aim is to encourage companies to create environmentally friendlier products that reduce harmful gas emissions during manufacturing and when in use by the end client, right through to their eventual disposal.

In the case of the Worcester Bosch Greenstar I System 15i, the ERP rating is "A".

How long is the warranty period on a Worcester Bosch Greenstar I System 15i system boiler?

Worcester Bosch’s Greenstar I System 15i boiler includes a parts and labour warranty of 7 years.

Worcester Bosch Greenstar i System 15i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 15i a system, regular or combi boiler?

If you’re looking for a system boiler for your house or flat, you may wish to the consider the Worcester Bosch Greenstar I System 15i.

System boilers share many similarities with more traditional heat only boilers, like the need to program the times you want them to provide you with heat and hot water - just use the control panel to do this.

Where they differ from regular boilers is that they do not require a separate cold-water tank - everything is done within the hot water cylinder, which contains built-in circulating pumps. This makes them easier to install as there is one less component to fit and makes them more suitable for properties with no loft space, smaller lofts or for homeowners who are considering converting their loft.

As long as you have programmed your system boiler in advance, you will have the hot water you need ready for whenever you want to use it. Once the water is heated, it will remain available, warm, inside the tank until it’s all used up. It will then draw more water from the mains to start heating so that it can provide heat and hot water for the times you've told the system boiler you need it.

Is the Worcester Bosch Greenstar I System 15i system boiler suitable for my house or apartment?

Selecting the right boiler for your property means selecting 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".

The output of a boiler is measured in kilowatts. The output level determines the maximum power a boiler can use in heating the water needed for the baths, showers, taps and radiators in your home.

It's important to choose a boiler with an appropriate level of output for your property. Your boiler should be able to cope with periods of peak demand in your property and not just your average usage.

An output rate that is too low will result in an inadequate supply of hot water, while an output that is too high will mean the boiler will cost more to run than is necessary.

The output of the Worcester Bosch Greenstar I System 15i system is 15 kW kilowatts, so which types of property would this be appropriate for?

Most Gas Safe boiler installers would recommend that this Worcester Bosch Greenstar i System 15i System boiler would be suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


The size of the Worcester Bosch Greenstar I System 15i

The dimensions of the Worcester Bosch Greenstar I System 15i are 710 mm tall, 400 mm wide, and 330 mm deep.

Is the Worcester Bosch Greenstar I System 15i a condensing or non-condensing boiler?

We recommend the Worcester Bosch Greenstar I System 15i as it is a modern condensing gas boiler from a trusted manufacturer with a reputation for supplying highly energy-efficient boilers.

Condensing boilers capture the heat still present in water vapour condensation and flue exhaust gases and recycle it back into the heating system. With this extra energy, your boiler can, among other tasks, reheat colder water coming back from your radiators without having to burn more gas.

Condensing boilers significantly reduce your quarterly gas costs and they're better for the environment.

Does the Worcester Bosch Greenstar I System 15i system protect the environment?

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

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.

Will you be helping the environment if you decide to install a Worcester Bosch Greenstar I System 15i system in your home? Let’s look at the figures.

By law, boilers manufactured and supplied in the UK must achieve a SEDBUK rating of "A" and work at a 92% minimum efficiency. Before April 2018, a minimum of 88% energy efficiency needed to be achieved (88/89% = SEDBUK "B" and 90% = SEDBUK "A").

Following official testing, the Worcester Bosch Greenstar I System 15i was given an efficiency rating of 94% with a SEDBUK rating of "A".

Energy efficiency is a measure of how much energy is used and how much is wasted when a boiler is operating.

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 15i has a rating of "A".

Am I covered if the Worcester Bosch Greenstar I System 15i system boiler breaks down?

The Worcester Bosch Greenstar I System 15i boiler comes with a parts and labour warranty lasting 7 years.
