Is a Worcester Bosch Greenstar 15Ri regular gas boiler suitable for my home?

The Greenstar 15Ri is the second smallest in the Greenstar Ri series after the Greenstar 12Ri, so it would be enough for your house if it has around 10 radiators and low demand for heating. Other regular boiler models in the same series (18Ri, 21Ri, 24Ri, 27Ri, and 30Ri) might be a better fit, depending on your house’s size and demand for heating and hot water.

However, bear in mind that regular boilers need expansion tanks in the loft and a hot water cylinder. We recommend installing a new regular boiler only if you are replacing an older regular boiler model.
