The Worcester Bosch Greenstar 21Ri is a condensing regular gas boiler with an output rating of 21 kW.
How efficient is the Greenstar 21Ri?
If you’re looking for a heating system that could help to lower your energy bills then the Greenstar 21Ri is a great option thanks to a 92% efficiency rating and ErP A-rating for heat.
Is the output rating suitable for my home?
The 21kW output rating makes the Greenstar 21Ri ideal for installation in homes with 10-15 radiators and 1-2 bathrooms.
Does the Greenstar Ri range include any other outputs?
This range of regular boilers are available in a number of different outputs, including 12 kW, 15 kW, 18 kW and 24 kW in addition to this 21 kW model.
Is a regular boiler suitable for my home?
A regular boiler should be installed into properties as part of an open vent heating system. This means that in addition to the boiler there will also be a cold water tank in the loft and a hot water cylinder.
How long is the warranty period?
A 5 year warranty is available as standard which can be extended to 7 or 10 years when certain terms and conditions are met.
What are the key features of the Greenstar Ri?
Greenstar Ri boilers feature simple-to-use controls and can be paired with Greenskies solar panels. Plus, if you choose to have the boiler fitted into a garage or loft area, then the frost protection feature will prevent it from freezing during the winter months.
How big is this boiler?
Thanks to compact dimensions of 600 x 390 x 270mm (HxWxD) the Greenstar Ri can be installed into a standard kitchen cupboard.
