Worcester Bosch Greenstar i System 9i System Gas boiler frequently asked questions

Is the Worcester Bosch Greenstar I System 9i a combi boiler, system boiler or regular boiler?

Looking for a gas system boiler for your flat or house? Then the Worcester Bosch Greenstar I System 9i may be an option you should consider.

System boilers need a hot water cylinder to work - normally fitted inside an airing or landing cupboard or similar spot. Unlike heat only boilers, they do not require a separate cold water tank, making them a more suitable choice if you have no loft, lack space in the attic, or are planning to do a loft conversion.

These boilers distribute hot water around your home to your taps and radiators using (often built-in) circulating pumps and they're easier to install as there is one less component (the water tank) to find room for. A system boiler needs to be programmed to tell it what times you want heat and hot water - unlike combi boilers, they don't provide hot water on demand.

Is the Worcester Bosch Greenstar I System 9i 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 a boiler, however, size does not mean how big the boiler is, it means how much power it has.

The amount of hot water you get from showers, bathrooms, and sinks and heat from your radiators depends on your boiler's output (measured in kilowatts). The higher the level of output, the better your home will be heated and you can be more certain that the water from your taps will be as hot as you want.

However, you must be careful. You might not get the hot water you want if your boiler output is too low. If it's too high, you'll be paying more than you need to for gas.

With the Worcester Bosch Greenstar I System 9i system's output at 9 kW, which types of property would this Worcester Bosch Greenstar i System 9i System boiler be most appropriate for?

An experienced boiler engineer would recommend that this Worcester Bosch Greenstar i System 9i System boiler would be a suitable installation choice for smaller homes and apartments with up to 10 radiators and one bathroom.


What size is a Worcester Bosch Greenstar I System 9i boiler?

The Worcester Bosch Greenstar I System 9i has the following dimensions - 710 mm high, 400 mm wide, and 330 mm deep.

Worcester Bosch Greenstar I System 9i – condensing or non-condensing?

We recommend that, if possible, you select one of the very latest condensing gas boilers on the market like the Worcester Bosch Greenstar I System 9i.

Condensing boilers are better for the environment because they capture and recycle the heat still present in flue exhaust gases and water vapour condensation for re-use, meaning lower greenhouse gas emissions.

They're also a lot cheaper to run meaning that, if you're replacing a very old and inefficient boiler, the savings on your gas bill over 5-10 years add up to more than you pay for the boiler itself.

Is the Worcester Bosch Greenstar I System 9i system an environmentally friendly boiler?

Many homeowners are becoming increasingly concerned about how they heat their homes and the impact it has on climate change and other important environmental issues.

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.

Do the figures suggest that installing the Worcester Bosch Greenstar I System 9i system at your property would help in the fight against climate change?

Under current UK law, all boilers must achieve a minimum energy efficiency level of 92% (a low to good SEDBUK "A" rating). The minimum level was raised from its previous 88% in April 2018.

Energy efficiency scores are intended to inform consumers of the amount of energy used and wasted when a boiler is in normal operation.

The Worcester Bosch Greenstar I System 9i was awarded an efficiency rating of 93% with a SEDBUK band rating of "A".

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 I System 9i has a rating of "A".

How many years' warranty does the Worcester Bosch Greenstar I System 9i system come with?

The parts and labour warranty offered with this Worcester Bosch Greenstar i System 9i System boiler covers you for 7 years.

Worcester Bosch Greenstar i System 9i System Gas boiler frequently asked questions

What kind of boiler is the Worcester Bosch Greenstar I System 9i - standard, combi or system?

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 9i.

Like heat only boilers, system boilers require a hot water cylinder to work - the cylinder stores and keeps water warm for use throughout the day. Hot water can be distributed to multiple showers and taps simultaneously, making system boilers suitable for larger families and properties with more than one bathroom.

System boilers differ from standard boilers in that they do not require a cold water tank, making them suitable for properties with no loft space or if you are planning a loft conversion. As the boiler's major components, including the circulation pump, are built-in and no water tank is required, system boilers are easier to install than regular boilers.

This type of boiler does not heat water instantly like a combi boiler - instead, you need to use the control panel to set the times when you want heating and hot water to be available for your home.

Is a Worcester Bosch Greenstar I System 9i system boiler suitable for my house or flat?

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

Your boiler’s output is a measurement of the power it has available to heat the volume of water required for your taps and radiators. The higher the output rate, the more water it can heat.

You need to be careful to select a boiler with the optimal level of output for your property though. That's because, if your boiler output is too low, your water and radiators will often not be as hot as you want them to be. If the output is too high, you’ll be paying more for gas than you need to.

The output of the Worcester Bosch Greenstar I System 9i system is 9 kW, so which types of property would this Worcester Bosch Greenstar i System 9i System boiler be appropriate for?

A PlumbProud boiler engineer would recommend that this Worcester Bosch Greenstar i System 9i System boiler is suitable for smaller homes and apartments with up to 10 radiators and one bathroom.
