Will the Worcester Bosch Greenstar 24Ri be suitable for my home?

Its central heating output of 24kw means it can efficiently heat a 3 to 4-bedroom property with up to 10 radiators. Despite the cold-water tank and hot water cylinder that always come with a regular heating system, you would need to consider a larger boiler such as the 28Ri or 30Ri if you're planning to extend your existing property, or if have more than one bathroom.

In addition to finding the correct size for your home's central heating system, the engineer should also check your pipework to ensure that it matches up to the specification.

Controls

Worcester Bosch offers the standard boiler controls on the boiler itself for controlling temperature output and timing capabilities. Your system should also include a hot water cylinder thermostat and programmable room thermostat so that you can set temperatures and schedules for your heating. The slight drawback with this boiler is the lack of compatibility with Worcester Bosch’s smart thermostat, the Wave. Alternatively, you can still opt for the Nest thermostat which is compatible with heat only Worcester boilers.

The Nest is a highly intelligent thermostat that allows you to schedule your heating, monitor energy use, and remotely switch your heating on and off while you’re away from home if you have a working internet connection. The smartphone app will also track your GPS location via the app to switch on your heating when you’re on your way home. If you'd prefer a simpler digital thermostat, the Greenstar Comfort may be a better option.

Size

The Worcester Bosch Greenstar 24Ri is ideal if you're looking to fit your boiler into a kitchen cupboard. This boiler, in particular, is compact at only 600x390x270mm. Despite the boiler being suitable for small to medium-sized homes, remember that you will also need to consider the extra space needed for a hot water cylinder and loft space for a large water tank.

Warranty

If you’re worried about your boiler breaking down any time soon or a fault appearing out of thin air, Worcester Bosch offers a standard 5-year warranty with each boiler in the Greenstar range which should give you sufficient peace of mind. You could also opt for an extended warranty of up to 10 years if you decide to have it installed by a Worcester Accredited Installer.

Energy Efficiency

The ErP directive tests each boiler and energy product to ensure that they pass certain performance criteria. If a boiler is tested and comes out with a poor efficiency rating, the directive will step in to recommend design improvements to reduce the amount of energy wasted. In this regard, the 24Ri is highly efficient with an ErP rating of 89.2% (an A grade for efficiency), which is great if you wish to save on your energy bills and get rid of your old energy-wasting boiler.

Verdict

The Worcester-Bosch Greenstar 24Ri is perfect for small to mid-sized homes with one bathroom and more than capable of filling up a bath tub in no time.
