ENERGY EFFICIENT SOLUTIONS SUITABLE
FOR CENTRALISED BOILER PLANTS
The Meibes brand and German heritage is renowned for its precision engineering quality and
innovative designs that deliver unparalleled performance, efficiency and ease of installation.
Meibes Heat Interface Units (HIUs) facilitate the use of
centralised systems for space heating and domestic
hot water in multi-residential buildings. They are high
performing units, engineered with fully tested and
approved components, designed to provide optimum
performance for end users, while ensuring that they are
easy to install and maintain.
Pegler Yorkshire also holds a comprehensive range
of spares for fast delivery throughout the UK.
Meibes HIUs are pre-fabricated units linked to the
central heat source(s) via a network of three pipes –
heating flow and return and a separate potable water
feed. A zone valve in each unit, linked to a standard
timer and room thermostats, controls the space heating
for each apartment.
A patented Proportional Modulating (PM) valve
intelligently prioritises the requirement for domestic
hot water (DHW) over heating, in a similar way to a
combi boiler.
A COMPREHENSIVE RANGE
FOR ALL APPLICATIONS
The Meibes HIUs offered by Pegler Yorkshire have
been designed to meet the specific needs of the
UK market. For example, Meibes HIUs for the UK
are configured for top-entry pipework for ease of
installation in ceiling voids
The breadth of the Meibes HIU range delivers solutions
for all types of centralised heating networks serving
multi-residential accommodation, ensuring effective
control of heating and DHW in apartments and other
spaces. The design of HIUs facilitates a balanced system
that delivers consistent performance, irrespective of
variation in hot water demands or how far the units are
from the plant room.
TYPICAL APPLICATIONS
Private apartments
Local Authority accommodation
Housing Associations
Student accommodation
Nurse accommodation
Sheltered housing.

“Whatever the application, Meibes HIU have
the authoritative solution”
DESIGN
BUILD
Performance
Installation innovation
Pegler Yorkshire has various high performance Meibes
HIU products that are suitable when designing
apartments with multiple bathrooms. These ensure
reliable performance for individual use and against the
overall building requirements. Guidance on network
and temperature flow rates can also be provided by the
Pegler Yorkshire team.
The Meibes HIU range is part of Pegler Yorkshire
Connect & Control, which fully recognises the
importance of minimising installation costs whilst
ensuring the building performs efficiently and optimally.
Meibes HIUs were one of the first to be designed with
a first fix rail which is available to aid staged installation,
supporting the primary network set-up.
Allocating design space
No special commissioning required
Meibes HIU headline A2 RX Indirect Heating and
Domestic Hot Water units are compact in size at only
500mm wide, enabling them to be fitted into minimal
cupboard space. This also provides the option to fit
them into an appliance space. Further options are also
available for direct heating units at 650mm wide.
Meibes HIUs are designed to remove complications
and provide clarity on installation. There is no need to
have a specialist for commissioning as the standard
installation process requires a competent installer to
simply follow the specifier’s set-up parameters.
UK solution
Pegler Yorkshire is one the leading manufacturers
of commercial plumbing and heating systems. Our
expertise and experience enables contractors to
benefit significantly when it comes to project costs, and
technical and service support, by using a connect and
control system they can trust.
Pegler Yorkshire ensures that UK experience, system
design and installation and practices drive the solution
to the product, which is why the Meibes range of
HIUs is designed to meet UK needs. As a result there
is no need to compromise and adapt to HIU’s with a
European configuration.

ENERGY EFFICIENCY WITH
IMPROVED SAP RATINGS
Centralised heating systems are becoming increasingly
popular for multi-residential properties as they offer a
number of key advantages over decentralised systems
with individual boilers in each apartment. These include:
Improved energy efficiency
11% improvement in SAP ratings
(compared to decentralised systems)
No gas installation throughout the building
Energy-saving features of Meibes HIUs
Meibes HIUs operate on a ‘no demand-no flow’ basis,
so that when there is no demand for heating or DHW
the unit effectively goes into standby. The arrangement
minimises the demand on the main network, reduces
energy consumption and ensures the apartment is
not over-heated.
The performance of the units is based on primary flow
temperatures of 65°C, enabling use with low carbon
heat sources such as heat pumps. The resulting low
return water temperatures also help to maximise
condensing when condensing boilers are used.
No flues in apartments
Ease of access to heating plant for maintenance
Simple integration of low carbon and renewable
heat sources.
To help ensure minimum heat losses from the system,
all pipework is pre-insulated to save energy and reduce
onsite insulation work. For further energy savings an
A-rated pump aligns water flows with heating demand
to minimise pump energy consumption.

CHOOSING THE BEST SYSTEM
FOR YOUR APPLICATION
The comprehensive Meibes HIU range ensures that these units can be used with a range of
different system configurations.
INDIRECT SYSTEM – A2 RX/A2 UX
SYSTEM BENEFITS
The indirect system provides both indirect space
heating and indirect DHW. The system uses twin
heat exchange units to supply instantaneous DHW
and space heating.
The Proportional Modulating Valve operates in the
same way as a combi diverter valves. Whenever
there is a call for DHW, the PM valve diverts the
primary flow through the heat exchanger to generate
DHW, using all available energy to support the DHW
demand. Typically, this results in the heating circuit
being closed for just a few minutes, having minimal
impact on occupant comfort.

When using a cylinder system the primary circuit is
separate to the secondary circuit, so that hot water
is supplied from the cylinder, ensuring hot water is
always available. The system incorporates a zone
valve which is controlled by standard controls such
as a time clock and a room thermostat to switch off
the unit when there is no demand, thereby reducing
network load.

FIX RAILS
First fix rails allow a faster installation that can be
staged to align with progress on other parts of the
project. For example, the first fix may be carried out
in the early stages, with the HIUs themselves being
installed later in the project schedule. This reduces
the risk of onsite damage to the HIUs.
The first fix rail is secured to the wall in the
appropriate position allowing all plumbing
connections to be made, pressure tested, flushed
and filled. Depending on the nature of the contract,
this may also support staged billing for work carried
out and products installed.

of heat energy use in individual apartments. Use of
factory-fitted heat meters reduces onsite work and
enables optimum use of skilled labour for more
complex tasks. Factory-fitted units are pressure
tested before delivery to site.

DATA EXTRACTION
The most popular form of data extraction from
heat meters is an Mbus network connection,
which can be pre-fitted to the heat meter. The
data extraction unit sends a master signal to slave
meters, which then report on energy consumption
data. The readings can be sent via email or pulled
directly from the data logger.
Where required, heat meters can be fitted with
radio-based data extraction systems.

MEIBES HEAT INTERFACE UNIT
TECHNICAL GLOSSARY
Meibes heat interface unit
Features
Designed specifically for UK
30
Benefits
Designed to meet UK requirements to avoid installation and performance issues. Comprehensive spare stocks
available in UK.
Top entry connections
Top entry pipework facilitates pipework runs in ceiling voids for quicker, simpler and more cost effective connection.
First fix rail
Enables faster installation and facilitates staged installation to suit the project timetable and contractor’s schedule.
Also allows earlier primary testing of the main heat network. The first fix rail allows all plumbing connections to be
made, pressure tested, flushed and filled before installation of the main unit, thereby reducing risk of damage and
supporting staged applications for payment where appropriate.
All pipework is pre-insulated
Minimises heat loss for higher energy efficiency, while also improving end user comfort by preventing heat transfer to
property during summer.
Integrated Differential Pressure
Control Valve (DPCV)
Integrated DPCV make the system ‘self balancing’ and ensures each unit only draws as much energy/flow as it requires
in conjunction with a Proportional Modulating Valve. Results in a simpler design with improved control and less noise.
Vertically mounted, un-insulated
Domestic Hot Water heat
exchanger (DHW)
Uninsulated vertical heat exchanger accelerates cooling of DHW heat exchanger through convection and thermal
radiation, minimising limescale formation, maintaining high performance and extending life of units.
Proportional Modulating Valve
(PMV)
Gives priority to DHW generation over space heating to ensure full DHW performance. Primary flow rates are matched
to cold water input.
Carbon coated operating rod in
PM valve, with ceramic disk
Carbon coating provides self lubricating operation, with ceramic disc removing limescale each time the valve operates
to deliver a longer, trouble free, service life.
Indirect energy supply
Separates main primary circuit from secondary circuits, ensuring issues in either do not impact on the other. Also
provides clear demarcation where different contractors are used for primary and secondary circuit installation.
No demand – no flow
With no demand for hot water or heating the unit is effectively on standby with no flow (see trickle bypass). Minimises
demand on main network, reduces energy costs and avoids ‘overheating’ of space where unit is fitted.
‘A-rated’ pump
The electronic pump is an ‘A-rated’ Wilo pump which delivers energy-savings due to only using the minimum amount
of electricity.
Blending valve
Controls maximum temperature of DHW from the heat exchanger at 60ºC. The blend valve allows the temperature to
adjust from 60ºC down to 35ºC depending on the application requirement.
Trickle bypass (included)
Ensures that the prime flow is hot when the unit is switched off, ensuring quicker response times for DHW demand
and eliminating ‘cold legs’ in network where HIUs are some distance from the main network. Avoids need for bypasses
on risers, thereby simplifying network design.
Performance based on lower
primary flow temperatures – 65ºC
Ensures maximum performance with condensing boilers and supports use of low carbon heat sources (e.g. heat
pumps) with lower primary flow temperatures.
Return temperature limited
(RTL) valve
An optional RTL is available if required to allow the return temperature to be limited. This protects the boiler from
excessive temperatures.
Optional factory fitted,
heat meter
Allows accurate measurement of individual energy use. Pressure tested and fitted at factory, reducing on site labour and
risk. Range of options to suit project requirements – ultrasonic or mechanical. M-Bus, radio, manual reading, prepayment.
Potable water circuit
WRAS approved to meet UK requirements and compliant with European Drinking Water directive, in line with Pegler
Yorkshire’s commitment to highest quality and safety.
Warranties
2 year warranty on the unit and moving parts such as pump (on selected units).
Designed for ease of servicing
Ease of access to all components ensures annual servicing can be completed quickly and efficiently.
Reduced lifecycle costs
Product quality and ease of servicing ensure minimal cost of ownership with sustained high efficiency and performance.
Flexible stainless steel pipework
Reduces thermal expansion stresses for quieter operation during warm up and cool down. Easier future servicing
due to flat face connections. In the unlikely event of a need for component replacement, flexible pipework makes
re-connection easier.
Test points
Allows confirmation of flow pressure and temperature.
Strainers on primary and
secondary circuits
Help to capture debris from either circuit, thereby protecting heat exchangers and/or other components, as well as
extending service life. Strainer cleaning is included in annual servicing.
Vertically mounted insulated heat
exchanger for heating circuit
Ensures heating circuit heat exchanger remains at temperature without introducing ‘heat’ to the unit. Lack of cycling
and appropriate water treatments ensure that limescaling is not an issue.
Simple, straightforward
control wiring
External control wiring is similar to a conventional combi boiler and therefore familiar to installers.
