Greenstar CDi Classic
Features and benefits
The top-of-the-range, award-winning Greenstar CDi Classic is a high
performance boiler that is suitable for small, medium and large-sized
properties with one or two bathrooms. It has set the benchmark within
the industry for efficiency, reliability and ease of installation, while
achieving a market-leading output of up to 42kW.
The Greenstar CDi Classic offers the opportunity to range-rate the central
heating output to perfectly match the properties’ requirements which
reduces cycling and improves efficiency further.
As well as being the flagship boiler in our Greenstar combi range, the
upgraded CDi Classic now benefits from a number of new improvements
including higher DHW flow rates of 12.3, 14.3 and 16.4 to complement
the already class-leading 17.2 l/min performance.
The improvements to the control box now includes lead-free components
Greenstar CDi Classic is
available with DHW flow rates
of 12.3, 14.3, 16.4 and
17.2 l/min
for environmental benefits, a clearer display for temperatures and
commissioning settings, and a new short-circuit-proof PCB design that
removes the need for fuses on the low voltage circuits. The control box
casing is more water-resistant due to the removal of the transformer, while
the lift weight of the appliance has also been reduced to 47.5kg.
The Greenstar CDi Classic achieves 3 credit points within the Code for
Sustainable Homes and has an A rated annual efficiency of up to 90.2%
(SEDBUK 2005 value).

NEW
Features and benefits
The Greenstar Si Compact is the successor to the Greenstar Si combi boiler.
The all new Greenstar Si Compact has a host of performance-enhancing
features, including the revolutionary WB7 heat exchanger which enables the
appliances to deliver DHW flow rates of 10.2 and 12.3 l/min despite their
compact size.
Similarly to the CDi Compact, particular care has been taken with the design
of the hydraulic unit. Key components are positioned to provide easy access,
whilst the Heatronic 4i control box makes commissioning simpler. This menudriven unit features an LCD display which shows boiler status symbols and
system and commissioning parameters as well as giving access to service and
maintenance codes and diagnostics.
Building on installer feedback, the new Greenstar Si Compact has been
designed to make installation and commissioning easier and quicker and
comes supplied with a unique wall-mounting jig which enables the installer
to quickly pre-plumb all seven pipe connections without the boiler being

medium-sized properties with one bathroom.
Greenstar i Junior appliances have DHW flow 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 fixing points and options that
make hanging the appliance quick and easy. The wall-mounting jig allows
installers to quickly pre-plumb the condensate, CH flow, DHW outlet, gas,
DCW inlet, PRV installer connection & CH return without the boiler being
on the wall. Both models offer an A rated annual efficiency of up to 90.1%
(SEDBUK 2005 value).

The following diagrams show the wall-mounting jigs which
enable a simple and straightforward method of attaching
the boiler to the wall surface.
All Greenstar wall-mounting jigs have pre-drilled fixing
points and options that make hanging a Worcester
Greenstar quick and easy.
After fixing the jig to the wall, the appliance can be lifted
onto the jig and the union connections tightened. The
pipework can be routed behind the boiler without the
need for an additional wall spacing frame.

System Filter
At the centre of this innovative design is a highly powerful
magnet that removes the magnetic debris (magnetite) that
is present in the heating system water. The central location
of the magnet ensures that magnetite is collected quickly
and retained, maximising the overall protection. Any
non-magnetic debris is caught by the twin-action cyclonic
trap, a proven technology that offers a capacity to collect
up to 200g of magnetite a year.
NEW
The Greenstar System Filter has been extensively
tested in simulated systems, proving its effectiveness
in removing iron oxide, magnetite, limescale particles,
casting sand, welding debris, non-magnetic metal flakes,
Modern condensing boilers are precision-engineered and
designed to run with a clean water heating system. Over
time, dirty system water will damage a boiler and its
paint particles and other system pollutants.

The Worcester CondenseSure
auxiliary siphon
NEW
With climate change and extreme weather variations
becoming increasingly common, and very cold winters with
temperatures as low as -20°C being experienced, practices
such as externally-run condensate discharge pipework are
now being questioned.
The CondenseSure auxiliary siphon has been designed to
allow a more flexible approach to boiler siting.
Tested to extreme temperatures
The CondenseSure has been extensively tested under
simulated extreme weather conditions and proved its
effectiveness in preventing frozen condensate at -15ºC
for a sustained period of 48 hours.
CondenseSure principle of operation
Within most condensing boilers, there is an internal siphon
which holds around 100ml of condensate before being
released down the condensate discharge pipe. A typical
high-efficiency condensing boiler will generate up to 2

• Significantly decreased or even eliminated

Ease of installation
Fitting to a combi boiler
The CondenseSure has been designed with ease of
installation in mind and is suitable for most boiler
applications. For maximum effectiveness, it should
be installed immediately beneath the boiler where
it is clipped on to the boiler’s heating flow pipe and

the installation:
1 x flue turret elbow
• The concentric flue system must be inclined at
600mm (125mm dia.) of flue duct including terminal
3º (52mm per metre) from the appliance, to allow
(as measured from centre of flue outlet)
condensate to drain back into the boiler
1 x weather sealing plate
• A white plume of condensation will be emitted from
1 x internal plate
the terminal because the appliance operates at high
Part No. 7 719 003 702
efficiency. Care must be taken when selecting the flue
terminal position
• To achieve a maximum flue length, one of the extension
flue kits will need to be cut so that the permitted
maximum flue length is not exceeded
• Horizontal flue options 1-6 illustrate common flue
installations. Other configurations of the flue system are
possible up to, and not exceeding, the stated maximum
flue lengths.

A Greenstar combi with Greenfloor
heating – a great combination
Whether you are upgrading an existing system or installing a
new system, Worcester Greenfloor heating can provide an
ideal alternative to traditional radiators. Worcester’s
Greenfloor heating system uses a water-filled pipe system
that turns the floor into a large surface area radiator. The
pipe system gently warms the space above it through a
combination of radiant energy and heat conduction.
In a modern, well-insulated space, where heat loss factors

can act as the primary heating source and, in most cases,
no other space heating methods will be required.
Underfloor heating operates with lower water temperatures
than traditional radiator systems. This makes it suitable
for use with Worcester condensing boilers, ensuring they
remain at their optimum efficiency, with significant
energy savings.
As there are no radiators to take up space, Worcester
