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?

Worcester Bosch’s Greenstar I System 15i is one you might consider if you’re looking for a system boiler for your house or flat.

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.

Should I install a Worcester Bosch Greenstar I System 15i system boiler in my house or apartment?

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

Your boiler should be able to cope with peak hot water demand in your property and not just your average hot water usage. The output rate of a boiler is measured in kilowatts and tells you how much power a boiler can use to provide hot water to your taps, showers and radiators.

If the output of your boiler is too low, there will often be times when your water isn't as hot as you want. But if your boiler output is too high, it will be more costly to run (often unnecessarily).

The output of the Worcester Bosch Greenstar I System 15i system boiler is 15 kW kilowatts. Which types of property would this be appropriate for?

An experienced PlumbProud boiler engineer would likely recommend this Worcester Bosch Greenstar i System 15i System boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


Dimensions of the Worcester Bosch Greenstar I System 15i boiler

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

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

We always recommend to clients that they select the very latest condensing boiler for their home.

Condensing boilers like the Worcester Bosch Greenstar I System 15i are more efficient with the gas they use in operation, meaning that you'll benefit from lower fuel bills. Condensing boilers are also better for the environment.

They achieve their efficiency by capturing and recycling the heat still present in the water vapour condensation and flue exhaust gases created when a boiler burns gas to get the energy it needs. It then reuses that recycled heat to perform a number of tasks, including heating the colder water that comes back to your boiler via the radiator.

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

Concern for the environment is causing more and more homeowners to think about how they heat their homes and its impact on climate change.

Central heating creates 14% of the UK’s greenhouse gases. And in Britain's larger cities, gas boilers are responsible for dangerous levels 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.

The energy efficiency rating of the Worcester Bosch Greenstar I System 15i is 94% with a SEDBUK band rating of "A".

Energy efficiency tests record how much energy is wasted on non-core functions during an operation.

By law, all boilers manufactured and supplied in the UK must have a minimum energy efficiency performance level of 92% (equivalent to a SEDBUK "A" grade). Up to April 2018, the minimum performance level was 88% (88% and 89% are equivalent to a SEDBUK "B" grade and 90%+ an "A" grade).

The Energy Related Products Directive (ERP) intends to reduce the amount of energy consumed by individual products over their entire lifetime, from the initial manufacturing process to final disposal and at all points in between.

The legislation is designed to encourage manufacturers to create products that are more environmentally friendly and which result in a reduction in harmful gas emissions.

The ERP rating for the Worcester Bosch Greenstar I System 15i is "A".

Does the Worcester Bosch Greenstar I System 15i system boiler come with a warranty?

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

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

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

You may wish to consider installing the Worcester Bosch Greenstar I System 15i if you are looking for a system boiler for your house or flat.

System boilers are suitable for larger homes where there is a higher-than-average demand for hot water and heating.

Through their use of a hot water cylinder, they provide hot water on demand during the day - as long as there's enough water left in the cylinder. Just let the boiler know when you want hot water for your radiators and taps via the programming panel and, subject to tank size and household usage, it'll be there for you.

Unlike heat only boilers, there is no requirement to find room in the attic for a cold water storage tank. System boilers are therefore quicker, easier and cheaper to install.

Is the Worcester Bosch Greenstar I System 15i system boiler the right choice 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.

The output of a boiler is measured in kilowatts and tells you how much power it has available to heat the water it sends to your hot taps, showers and radiators. The greater the demand for hot water in your home, the larger the output you will need.

It is important to select a boiler with the optimal output rate. Choose one with too high an output and your gas bills will be too expensive. Choose one with too low an output and sometimes the water in your radiators and coming out of your taps will be barely lukewarm.

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

An experienced PlumbProud boiler engineer would likely recommend this Worcester Bosch Greenstar i System 15i System boiler as suitable for smaller homes and apartments with up to 10 radiators and one bathroom.


The size of the Worcester Bosch Greenstar I System 15i in millimetres

The Worcester Bosch Greenstar I System 15i measures 710 mm high and 400 mm wide by a depth of 330 mm.

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

The Worcester Bosch Greenstar I System 15i is a condensing gas boiler - this is the type of boiler we recommend to most clients because they're better for the environment and they will save money on annual fuel bills.

A condensing boiler captures and recycles the warmth still present in both the flue exhaust gases and water vapour condensation created when gas is burned to provide your boiler with power.

This means it needs less gas to operate and it uses this extra energy to perform a number of tasks, including heating the colder water that comes back to the boiler from the radiators in your home.

How energy efficient is the Worcester Bosch Greenstar I System 15i system boiler?

With more and more people concerned about climate change, how we heat our homes and the damage it does to the environment is increasingly being questioned by British homeowners.

Central heating accounts for 14% of greenhouse gas emissions in the UK. In larger British cities, gas boilers emit dangerous levels of nitrogen dioxide into the atmosphere.

Will choosing to install a Worcester Bosch Greenstar I System 15i system in your home help the environment? Let's review 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 (ERP) came into force in 2015. This legislation was introduced to encourage manufacturers to create more energy-efficient products and it covers all products that consume energy during their lifetimes, including energy used during production and at the point of disposal.

The ERP assessors assigned a rating of "A" when testing the Worcester Bosch Greenstar I System 15i.

What length of warranty does the Worcester Bosch Greenstar I System 15i come with?

The parts and labour warranty on the Worcester Bosch Greenstar I System 15i lasts for 7 years.
