How efficient is the Greenstar 24i?

Greenstar i system boilers are highly efficient heating systems as shown by the 94% efficiency and ErP A-rating. As a result, you could see your heating bills drop rather considerably.

Is the output rating suitable for my home?

A central heating output of 24 kW is ideal for any properties with around 15 radiators. Then the cylinder allows it to meet demands of 2 or more bathrooms.

Are any other options available in the range?

If the 24 kW output of this boiler is suited to the heating demands of your home then there are lower outputs of 9 kW to 21 kW and higher outputs of 27 kW and 30 kW. A Gas Safe registered engineer will be able to recommend the most suitable output for your home.

Is a system boiler suitable for my home?

System boilers are installed alongside a hot water cylinder which allows them to meet higher demands for hot water in properties with 2 or more bathrooms. So for a system boiler to be suitable for your home then you’ll need more space than a combi boiler would need.

How long is the warranty period?

An extensive warranty period of up to 7 years is available when installed by a Worcester accredited installer.
