Product Description
The multi award winning Greenstar 12i system boiler is manufactured by Worcester Bosch.
How efficient is the Greenstar 12i?
The Worcester Bosch Greenstar 12i system boiler packs a punch with it's high energy efficiency rating of 94%. This makes it an ErP A-rated boiler which could help to lower your heating bills.
Is the output rating suitable for my home?
A 12 kW output rating makes this model well suited to homes with up to 10 radiators. As a system boiler, it stores domestic hot water in a cylinder so can meet the demands of properties with multiple bathrooms.
Are any other options available in the rang?
The Greenstar i range of system boilers has no shortage of options as it includes models with outputs from 9.2 kW right up to 30 kW. So, there's a heating system to match the needs of almost any home.
Is a system boiler the right choice for my home?
System boilers directly heat the heating system while warming domestic hot water in a cylinder. While this does mean that additional space is needed for a cylinder, they can meet higher demands for hot water. This makes the a perfect options for homes with 2 or more bathrooms.
How long is the warranty period?
A warranty period of up to 7 years is available so you'll be well covered after the installation.
What are the key features of the Greenstar 12i?
The high efficiency of this boiler is achieved thanks to a robust aluminium-silicon heat exchanger - exclusive to Worcester-Bosch boilers.
In addition, a heat exchanger with an extra large surface to allow exhaust gases to cool to around 55'C such that the latent heat contained in them can be used effectively rather than disappearing out of the boiler flue. This ability to extract as much useful heat as possible from each unit of gas consumed is what allows the Worcester-Bosch Greenstar 12i System to operate so efficiently. In doing so the Worcester-Bosch Greenstar 12i System also helps to reduce the amount of carbon dioxide (CO2), the main contributor to climate change, released into the atmosphere.
This award winning System boiler does require a hot water storage cylinder, but all the other major components including the expansion vessel, circulating pump etc. are built in to the boiler unit itself and are wired, plumbed, and tested as a complete system.
This boiler is also recommended by the Energy Saving Trust, which is a testament to the efficiency this boiler has achieved.
How big is the Greenstar 12i?
The Greenstar i System boilers are wall-mounted and designed to be compact, which makes them a good option for small to medium sized properties. This particular model measures 710 x 400 x 330mm (HxWxD).
