Product Description

The Greenstar 27I is a highly efficient condensing system gas boiler designed and manufactured by Worcester Bosch.

How efficient is the Greenstar 27i?

A 92% efficiency rating makes this an ErP A-rated boiler that could lower your heating bills when replacing an older boiler.

Is the output rating suitable for my home?

Thanks to a 27 kW output rating this is a powerful boiler which can meet the heating demands of homes with as many as 20 radiators.

Are any other outputs available in the range?

Should you need a more powerful system boiler then a 30 kW model is also available. There are lower outputs from 9 kW up to 24 kW too for smaller properties.

Is a system boiler suitable for my home?

A system boiler is a great option for your home if you have 2 or more bathrooms and a high demand of hot water. This is because they’re installed alongside a cylinder which stores water and can provide a strong pressure to multiple taps or showers at a time.

What are the key features of the Greenstar 27i?

With the Greenstar being compatible with Greenstore cylinders it can become an ever higher efficiency system as well as making perfect for a complete Worcester system for your home. This boiler is easy to use and comes with simple boiler controls that are clear and easy to use and that help you to make sure your home is as comfortable as possible (as well as being great economically).

This boiler has a wide range of accessories that it is compatible with, such as the Greenskies solar panels – another great way to help you save money and energy with. It also comes with a low energy pump, helping to reduce electrical usage and large condensesure style siphon that is built into the unit, helping to protect your boiler from frost.

How big is the Greenstar 27i?

This is a compact wall-mounted boiler with dimensions of 690 x 390 x 280mm (HxWxD).
