Greenstar Highflow CDi
Features and benefits
Energy efficient
Benefits to the installer
Greenstar Highflow CDi condensing combi boilers are
• Familiar design so no surprises during installation
• Tried and tested heat exchanger, as used in the popular
SEDBUK A rated (2005). This means they have an average
annual efficiency of 90.8%, compared to the 78%
wall-mounted Greenstar CDi Classic series, provides long
efficiency achieved by non-condensing boilers. Therefore,
and reliable service
customers who upgrade to a Greenstar Highflow CDi
boiler not only reduce their gas bills, they also reduce
their carbon footprint.
• Ideal solution for properties with high hot water demand
and multiple hot water outlets
• Uses standard Worcester multi-directional fluing options
for ease of installation in a wide range of situations
• Supplied as standard with 12 litre expansion vessel,
3bar pressure relief valve, pressure gauge and automatic
air vent
• Built-in condensate pump increases siting possibilities
and helps to reduce the risk of frozen condensate
• Pump seizure protection reduces the risk of call-backs
• Easy to site with dimensions comparable to standard
‘white goods’ appliances.
Benefits to the end user
Keep hot facility
All Greenstar combi models have an in-built ‘keep hot’
facility which will keep the primary water within the heat
exchanger hot – approximately 2.5 litres volume. This will
ensure that hot water is delivered almost instantly to the
opened outlet.
• Significant reductions in energy costs thanks to latest
condensing technology and high efficiency heat exchanger
•
• Quick re-heat times
• Hot water at mains pressure without the need for a pump
• Frees up space by not requiring a hot water cylinder
• Modulating central heating and hot water outputs,
Exceptional flow rates even with multiple hot water outlets

Typical hot water recovery times
Example – Greenstar Highflow 440CDi
Example – Greenstar Highflow 550CDi
With an outlet temperature of 47.5°C, a 100 litre draw off can be
recovered by the boiler in approximately 5 minutes.
With an outlet temperature of 50°C, a 70 litre draw off can be
recovered by the boiler in approximately 3 minutes.

Optional plug-in controls
Increased SAP ratings
As well as all Greenstar combi models achieving very high SAP ratings for dwellings, the addition of an intelligent flow

Water Authority requirement
A direct mains cold water connection is permitted by Water
Authorities, however, it is recommended that reference
be made to local requirements. In the event of difficulty
contact the Worcester Technical Support Department.
Pipe sizing
Unless the mains pressure is low, a standard 22mm
diameter service pipe is normally suitable. A 22mm hot
water distribution pipe to the first branch is recommended

The Worcester Greenstar System Filter
Modern condensing boilers are precision-engineered and
A highly effective solution from the brand you can trust
designed to run with a clean water heating system. Over

or heat pump for a fraction of its cost. The filter is suitable
for 22mm piped heating systems.
Damaged boiler and system components
• Blockages in primary heat exchanger
• Increased wear on pumps
• Blocked valves.
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.
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,
paint particles and other system pollutants.
How the Greenstar System Filter removes
debris from the system water.
Heat exchanger damaged by system debris and pollutants
Reduced efficiency
• Energy efficiency loss equivalent to a boiler being
reduced from A rated efficiency to D rated, resulting
in fuel wastage
• Blocked radiators can reduce efficiency and
heating comfort.
A thermal graphic of a
blocked radiator
Debris in the system blocks the
efficient flow of water around
the system, thus affecting the
radiator’s heat distribution.
Installation
The filter can be installed almost anywhere in a heating
system, however to maximise the effectiveness, it should
be placed before the boiler and after the last radiator on
the return pipework.

The following criteria should be noted when planning
the installation:
• The concentric flue system must be inclined at
3º (52mm per metre) from the appliance, to allow
condensate to drain back into the boiler
• A white plume of condensation will be emitted from
the terminal because the appliance operates at high
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 1-8 illustrate common flue
installations. Other configurations of the flue system are
possible up to, and not exceeding, the stated maximum
flue lengths.
