Key features of the range
Suitable for small and large scale district heating
The Greenstar HIU is perfect for small scale district heating
applications such as flats and other multi-residential
accommodation, as well as buildings that use uneconomical
electric heating or have individual gas appliances in each
property. A centralised heating concept allows specifiers
to take full advantage of a low carbon heat source or a
modular/hybrid configuration with high efficiency boilers.
The Greenstar HIU is compatible with Bosch Commercial
and Industrial products for both new and existing multipurpose and multi-residential buildings, as well as large
estates that include commercial units.
DHW and space heating temperature control
The Greenstar HIU comprises of two heat exchangers,
one for providing instant hot water at a regulated
temperature and the second for space heating. The
maximum temperatures for both can be set at the time of
commissioning by the installation engineer or by using a
compatible Worcester or third party control.
Efficient operation
The HIU is an indirect appliance so the primary heating
circuit is hydraulically separated from the property’s space
heating by a plate heat exchanger. The unit operates only
when DHW or space heating is required, ensuring energy
efficient operation. Accurate measurement of the heat
energy used in individual properties is provided by the heat
meter which is fitted as standard on some models and
is available as an accessory on others.

Summer by-pass function
When fitted, the summer by-pass accessory, or ‘keep

necessary to heat up the supply side pipe work after a long
period of inactivity, this will minimise the time taken to
produce hot water at the tap or radiator.

Inside story
The Greenstar HIU has been designed to provide engineers with ease of installation and access to all components. The unit
is supplied with a separate pre-mounting rail, transported in its own compartment within the unit packaging, which allows
for pre-plumbing on site while leaving the unit unpacked and ready for installation when required.

Siting of appliance
HIU wall mounting diagram
The appliance is only suitable for installing internally within
a property at a suitable location. The unit is designed to be
sited on any fixed, rigid surface of at least the same size
1
as the appliance and capable of supporting its weight. The
unit dimensions and secured cover allows for mounting
between wall units in the kitchen area offering multiple
siting options. No wall surface protection is required

against heat transfer.
The appliance must not be installed in locations where the
ambient temperature is expected to drop below 0 degrees.
3
Installation
The Greenstar HIU is supplied with a wall template to
accurately mark the drilling holes for mounting the first fix
rail and main unit.
The first fix rail is supplied with isolating valves which allow
for pre-plumbing and commissioning of the system prior
to connection of the main unit, via integrated compression
fittings, for fast and easy installation.
4
System filling and make-up
To comply with the Water Authority requirements, the
system should be filled via a temporary hose connection
to the mains cold water supply, with a double check valve
assembly and test point fitted to the mains water side of a
temporary circuit. Alternatively, the optional keyless filling
loop allows the system to be filled directly from pre-treated
district water.
