Greenstar i Junior
Features and benefi ts
With more than 1 million boilers already installed in the UK, the well-
established award-winning Greenstar i Junior condensing boiler series,
with outputs of 24kW and 28kW are ideal for apartments and small to
medium-sized properties with one bathroom.
Greenstar i Junior appliances have DHW fl ow rates of 9.8 and 11.4 l/min,
making them suitable for a variety of locations, including kitchens, utility
rooms, bathrooms, airing cupboards, lofts or garages. They now feature a
number of enhancements including the addition of a DHW control to the
boiler fascia and the ability to be used with Worcester intelligent controls
for load and weather compensation. Switch mode power supply reduces
energy consumption in standby by 61% and lift weight by almost 1kg.
The Greenstar i Junior appliances come supplied with a pre-assembled
light weight wall frame, that has pre-drilled fi xing points and options that
make hanging the appliance quick and easy. The wall-mounting jig allows
installers to quickly pre-plumb the condensate, CH fl ow, DHW outlet, gas,
DCW inlet, PRV installer connection & CH return without the boiler being
on the wall. Both models offer an A rated annual effi ciency of up to 90.1%
(SEDBUK 2005 value).
