GREENSTAR HIU Series BESA Heat Interface Units Installation Guide
Heat networks Top to bottom integration
Heat networks are a key pathway within Government policy to decarbonise heat in our homes and commercial buildings. Their ability to incorporate waste heat and renewable energy at scale, have earnt them a central role, wherever there is dense urban living. Add to this their ability to easily convert to alternative energy sources, such as future Green gas, and it is not hard to see why they are regarded as the go-to option for many new developments.
Of course, heat networks are a complex integration of components, which come
together to make the whole system. How these components match together affects
the performance and reliability of the system as a whole.
Worcester Bosch are at the forefront of incorporating renewable technologies
into heat networks, supported by gas peak load boilers up to 38MW.
About BESA
BESA operate the UK standard for testing of heat interface units, which was
developed specifically for typical UK operating conditions. Its basis was
adapted from the Swedish District Heating Association F:103-7 test
methodology. The BESA test regime continues to evolve, as experience of UK
based heat networks grows and has become recognised as a key foundation for
the quality of a heat network.
The purpose of the BESA test regime is three-fold:
To enable the performance of different HIUs to be evaluated within the context
of typical UK operating conditions, thereby enabling heat network developers
to evaluate the performance of specific HIUs against design requirements.
To generate operating data on the expected performance of specific HIUs given
`normal’ operating parameters, to enable heat network operators to identify
anomalous performance.
To provide a framework for HIU manufacturers to evaluate the performance of
their equipment within the UK context, thereby feeding into their continuous
improvement development programmes.
One of the key benefits of the BESA test is to demonstrate independent
verification of the heat interface unit’s performance. Bosch E and KE HIU have
been tested and are BESA registered products.

Comfort controlled
Reliability assured
Heat interface units (HIU) are at the heart of every home connected to a heat
network. Their performance and reliability are key to lifetime costs and end
user satisfaction. They control the comfort levels in each home and often
represent the only part of the system the end user will come into contact
with.
Reliability and long service life, supported by spare part availability, has
been found by many heat network operators to be a top priority in regard to
HIU. Reliability enables them to maintain their service levels to their
customers. When connected to a heat network, consumers are completely
dependent upon that provision of supply for their DHW and heating needs. The
Worcester Bosch Greenstar HIU has a proven track record of reliability,
Manufactured within the UK and supported by our nationwide network of
engineers and technical team.
Quality counts when the CMA (Competitions and Markets Authority) market study
into heat networks, concluded that any future regulator of the industry must
protect customers from poorly designed, built and operated heat networks,
where developers have used cheaper options to meet planning regulations.
Return temperature limiters
HIU technology continues to evolve to help improve heat network performance. Return temperatures are one parameter of many that must be controlled to ensure the efficient operation of heat networks. The latest generation of electronically controller HIU have the ability to limit return temperatures, sent back into the network from the individual homes. Whilst not a substitute for correct sizing and commissioning of radiators, return temperature limiters can help to support the overall strategy in reducing heat loss.
