Our entire gas boiler range is able to run on a 20% hydrogen blend so your
customer can be confident it will run on gas for it’s lifetime.
Precise energy management
Each boiler can automatically modulate its output to precisely match the heat
demand, reducing fuel consumption and improving overall seasonal efficiency.
With cascades, modulation is from the lowest output of the smallest boiler up to the total load of all the boilers. The 50-100kW products can modulate at a ratio of 1:5 and both the 125kW and 145kW boilers modulate at 1:6.
Time and cost saving
The boiler’s small footprint increases installation flexibility, speeds up
installation time and improves access for servicing and maintenance, reducing
the need to have larger boiler rooms to achieve higher system outputs.
Patented ALU-Plus heat exchanger
The maintenance-reducing heat exchanger is lightweight, robust and allows for
a rapid transfer of heat. Combined with its fully insulated case, the boiler
is especially quiet in the industry, with our 50kW model being Quiet Mark
certified.
*Quiet Mark certification applicable to the Condens 7000 WP 50kW single boiler. **Applicable to GC7000 WP 50kW model variant only. Please refer to technical data table on page 6.

The inside story 9
Heat exchanger
Patented ALU-Plus heat exchanger
The precision engineered heat exchanger is constructed from a cast aluminium
silicate compound which is lightweight, robust and allows for a rapid transfer
of heat.
The heat exchanger uses the latest ALU-Plus technology that has been developed
by us, to increase durability and optimise efficiency. Fins on the outside of
the aluminium tubes increase the exterior surface area so that more hot flue
gas c omes into contact with the heat exchanger.
A spiral channel on the inside of the tube increases the internal surface
area, bringing more water in contact with the heating surface and ensuring an
optimum heat transfer. The wide channels on the heat exchanger ensure that the
flow resistance is minimised and this, combined with its fully insulated case,
makes the Condens 7000 WP incredibly quiet in operation.
Plasm-polymerised heat exchanger
The surfaces of the heat exchanger’s tubes are treated using a patented
plasma-polymerisation process which leaves the surfaces so smooth that the
heat exchanger effectively stays clean as no deposits can adhere to them.
Its extremely high efficiency is maintained and there is no need for
mechanical cleaning; the heat exchanger can be simply flushed through during
servicing.

Water system connections
When to use a low loss header or plate heat exchanger The Condens 7000 WP must
be installed on a sealed system in accordance with BS EN 12828.
For open vented systems or systems that are particularly contaminated, a plate
heat exchanger should be used to separate the boiler circuit from the main
system. Matched plate heat exchanger packs for the boiler or cascade output
capacity are available to make selection simpler (see control section for
guidance on positioning of flow temperature sensor).
For clean sealed systems where multiple heating circuits or DHW circuits
controlled by separate pumps are used, it is necessary to incorporate a low
loss header. Cascade kits with the appropriately sized low loss header
included are available as a pack (please refer to page 35 for part numbers).
The low loss header acts to hydraulically separate the boiler pump groups from
the heating circuit pumps and avoids hydraulic issues that could affect the
correct control of the heating system. Always use a low loss header (or plate
heat exchanger) where there is more than one pump in the system.
Residual pump head For single boiler applications, the matched boiler pump
group has been selected to cope with typical radiator heating systems that are
constructed in accordance with UK building regulations requirement of
separating zones above 150m2. Under these circumstances the residual head
available from the boiler pump should be sufficient to cope with most typical
radiator heating circuit resistance.
For older heating circuits that do not comply with modern building
regulations, or for applications with high system resistance, a low loss
header should be used.

Maximum temperature difference
Heating systems designed for use with condensing boilers such as our Condens
7000 WP are at their most efficient when the return temperature is below 55
degrees. To help achieve these conditions, industry guidance recommends
rebalancing older heating systems designed to operate at 82/71 to 80/60 (T
20K). When this is combined with weather compensated heating circuit
operation, the return temperature will regularly be below 55 degrees on all
but the coldest days.
However, the maximum temperature difference should be kept below T 25K. Above
this temperature difference the boiler will modulate its output to ensure it
continues to operate safely.
Water quality
We strongly recommend thoroughly flushing the system before filling it and
using only untreated tap water when filling the system. The use of dirty water
will lead to build-ups of sediment and corrosion, which can result in the
boiler malfunctioning and cause damage to the heat exchanger.
Do not treat the water with pH-adjusting substances (chemical additives) or
anti-freeze (other than Fernox Alphi 11) or water softeners. Sentinel X100 or
Fernox MB1 can be used to achieve the desired water quality. The concentration
of Sentinel or Fernox should be in accordance with the manufacturer’s
instructions for the volume of the water in the system.
Water treatment following the requirements of VDI 2035 may be used.
The pH of the heating system must be between 7 and 8.5. If this is not the
case, please contact our technical support team before proceeding, tel. 0330
123 9229.
Artificially softened water must not be used with the Condens 7000 WP.
Quality of the pipe work
When using plastic pipe work in the heating system, e.g. for underfloor
heating, it has to be oxygentight according to the relevant UK standards. If
plastic pipes do not comply with these standards, the system parts must be
separated using a plate heat exchanger.
Filling the system (water regulations)
In the UK, methods for filling heating systems are covered by the water
regulations. The regulations ensure that backflow of contaminated heating
system water does not enter the water supply. It is important to understand
these requirements and how they relate to the type of building (house or non-
house) as well as the boiler output size.
For most non-domestic applications there will be a need to comply with fluid
categories 4 and 5, meaning that a simple filler loop cannot meet the
requirements.
Gas supply requirements
Low gas pressure will lead to reduced boiler outputs, so it is important to
ensure the gas installation can provide the necessary supply capacity and
pressures.
For natural gas, the inlet supply pressure should be within 17mbar to 25mbar
(see installation manual for guidance when measuring gas pressures as the
appliance gas multi-function valve).
Before installation commences, the capacity of the gas meter supply should be
checked to be sufficient for all of the gas appliances connected to the
installation.
For the 50 and 65kW boilers in domestic properties where installers carrying
out the installation hold domestic ACS qualifications only, the installation
of the gas supply must comply with IGE/UP/1b. This means that the gas meter
must be no greater than 16m3/h, the pipework no more than 35mm and the
installation volume does not exceed 0.035m3.
LPG conversion
LPG conversion kits are available for all of the outputs. For LPG
installations, the gas supply pressure should be between 25mbar and 45mbar
with adequate protection for over and under pressure.
Ensure the siting of the appliance is not below ground level and that low
level ventilation meets the requirements of the appropriate standard.

A Single boiler installation internet-connected controls
Bosch EasyControl controller 7-736-701-341 (white) 7-736-701-392 (black)
The Bosch EasyControl is a smart internetconnected room thermostat, offering a
simple, stylish and intuitive solution to optimise home comfort.
When combined with our Smart TRVs, homeowners can easily control the heating
in each individual room, to achieve the perfect heating environment (feature
only available for 50-100kW models).
The device can be connected to the boiler using a 2-core cable.
3 way valve 7-736-701-881
3 way valve allows for priority DHW generation, must be used in conjunction
with a Sense II or EasyControl.
Plugs into the boiler’s harness plug 1 1/4″ connections.
You must ensure that the cylinder coil is rated to at least 50% of the
boiler’s output. If demand is lower than 50%, refer to control option B,
below.
B Single boiler installation standard controls
If an internet connection is not required for your install, the Sense II
controller in combination with expansion modules MM100 can be used. Where the
system also includes solar thermal, either the MS100 or MS200 can be used.
Where there are multiple heating circuits, a Sense I can be used to give
individual zone control.
Sense II 7-738-111-064 The Sense II control platform uses the EMS 2 Energy
Management System which allows advanced functions such as weather compensated
control and optimum start.
Weather compensation is particularly useful for larger buildings where it can
be difficult to locate a good reference room to suit the area being heated. A
north facing outside sensor is used to determine the correct flow temperature
needed to achieve the desired room temperature, based on a heating curve.
Local TRV’s on radiators, for example, can then fine tune the final room
temperature to suit the occupants.
Using weather compensation allows lower flow temperatures for large parts of
the heating season, which in turn leads to lower return temperatures to help
make the condensing boiler more efficient.
MM100 7-738-110-140 Used for additional heating circuit (maximum of 4) or additional DHW circuit (maximum of 1).
MS100 7-738-110-144
Module for integration of solar thermal panels.
20 Controls
The benefits of weather compensation
The Sense II controller can change the required temperature for different
heating circuits according to the outside temperature and is measured using a
small external sensor.
With mixed heating circuits this means that each individual circuit has its
own characteristics and the boiler will supply only the heat needed for
certain parts of the system. This is particularly effective in Spring and
Autumn so temperatures for the heating circuits can be reduced significantly
saving fuel and allowing the highest efficiency from the condensing process.

C Cascade installation BMS Led (Bosch controlling sequencing)
MC400 cascade sequencer 7-738-111-001 The MC400 simplifies the optimum running
of a cascade system when interfacing with an existing BMS.
By rotating the lead boiler it eliminates excessive wear in any one unit and
also interprets the 0-10V input signal from the BMS to modulate the heat
output of the cascade. This is all achieved without the need for programming
or complex set up and is a true “plug and play” control.
An individual MC400 can control up to 4 boilers and up to 16 boilers can be
achieved when five MC400 units are linked together, up to 2.2MW.
Wet sensor (part number 7-735-600-657) must be used in conjunction with the
MC400 cascade sequencer.
D Cascade installation BMS Led (BMS controlling sequencing)
MU100 BMS interface module 7-738-110-145 The MU100 is used for each individual
boiler and modules when interfacing with an existing BMS.
It can create a 230V fault signal, and has a 0-10V contact for signals from
the BMS to control the boiler flow temperature.

E Cascade installation internet-connected controls
BFU room thermostat 5-720-720 The BFU is a remote control which allows the
temperature to be adjusted from the end user’s living or working space. This
includes a room temperature sensor.
Bosch CC8313 intelligent commercial control 7-736-602-245 The CC8313 is an
intelligent commercial control offering internet-connected remote access and
weather compensation as standard.
The control unit has the ability to work alongside or independent of a BMS
system. With the addition of plug-in function modules, the CC8313 can be
expanded to cascade boilers, add multiple heating circuits and provide control
of two separate DHW circuits.
The CC8313 can control a DHW circuit as standard, additional function modules
will be required for mixed or unmixed heating circuits. The CC8313 has the
space available for up to four additional function modules.
Wet sensor (part number 7-735-600-656) must be used in conjunction with this
control (please refer to page 21 for more details).

F Cascade installation standard controls
Gives cascade control for use with existing heating and hot water time and
temperature controllers.
MC400 cascade controller 7-738-111-001 For heating systems where an existing
control system will be reused and is not capable of sequencing and rotating a
cascade, the MC400 is the perfect solution. The MC400 can control up to four
boilers as a single control unit, but can be connected to other MC400
controllers to control up to 16 boilers (requires five MC400s). The controller
will sequence the boilers to match the demand and rotate the lead boiler to
ensure even use across the cascade.
MC400 has several different configuration options that allow 0-10VDC or 230V
enable signals from an existing external controller. A 230V alarm signal is
also available to indicate a fault situation.
A flow sensor (part number 7-735-600-657) is required for the low loss header
or plate heat exchanger.
FM-MW heating and DHW control module 8-718-598-831
This controls one mixed or one unmixed heating circuit and one DHW circuit
(with cylinder load and circulation pump).

Flues and ventilation
The topic of fluing and ventilation for commercial boilers is a detailed one that crosses several industry standards and regulations.
To help guide installers and system designers, we have produced a dedicated
flue and ventilation guide for commercial installations, which is available to
download from our website.
Additionally, a separate flue manual is available for the Condens 7000 WP
boiler range, also downloadable from our website.
Concentric flue options Standard flue options are available for individual
boilers using room sealed (RS) concentric flue systems. The Condens 7000 WP
has an extensive range of concentric flue components available for horizontal,
vertical and plume management terminations.
C13 and C33 concentric flue lengths and reductions The following equivalent

Plume management flue kit For single boilers, sometimes finding a suitable
compliant flue termination position can be difficult. Plume management kits
allow termination positions to be raised up to a level where plume is less
likely to cause a nuisance, allowing more options for a compliant flue
termination position. The plume management kit replaces a standard horizontal
terminal and allows a concentric flue system to be used internally, where the
boiler is positioned some distance from the outside wall.
All external components are made from stainless steel to ensure a durable long
life flue system. Stainless steel bends and additional sections allow further
options depending on the site conditions.
For further information about permissible flue lengths, please refer to the
flue installation manual for the 7000 WP.

B23 open flues For situations when a suitable room sealed flue run cannot be found, open flue systems using existing chimneys or purpose made flue systems can be used. The Condens 7000 WP has a range of flue components for use with B23 open flue systems.
Flue via an existing chimney For individual boilers, DN110 flue system components are available to line existing chimneys and connect the boiler to the lining. Rigid sections, available in 500mm, 1,000mm and 2,000mm, can be used with flue spacers, terminal, and base sections to build a complete flue system. For chimneys that are not straight, DN110 flexible liners are available in 15m and 25m lengths. Installation tools are also available.
C93 room sealed flues Where a room sealed flue arrangement is desired, but it is not possible to use a standard concentric flue to achieve this, the C93 flue option using an existing chimney is possible. The chimney must be inspected and found to be sound, clean and of minimum size before this option can be considered. C93 flue systems use the chimney as a supply duct for combustion air via a special terminal and base section. The inner exhaust duct uses standard flue components similar to those described in the B23 flue for both rigid and flexible options.
Flues and ventilation 29
Cascade combined flue systems One of the advantages of a Condens 7000 WP cascade is the ability to combine individual boiler flues into a common flue header using off-the-shelf recommended flue components. There are two types of cascade flue systems, which should be considered at the design stage.
Natural draught cascade flues Cascade flue systems that rely on natural
draught are durable due to their simplicity. They require a minimum vertical
height and diameter based on the cascade output and can use existing chimneys,
operating as an open flue system.
Where no chimney is available, flues can be run externally using standard twin
wall stainless steel components. Internal flue runs must consider any fire
protected areas they may pass through and local Building Regulations.
Standard cascade flue headers are available to suit all common cascade
arrangements.
Over pressure cascade flues Where the use of a natural draught flue system is
difficult to achieve, due to chimney size and height restrictions, an over
pressure flue system can be used. This provides greater flexibility to achieve
compliant flue options in demanding situations.
Over pressure flue systems use an individual nonreturn valve at each boiler
flue exit to ensure there are no possibilities of flue spillage when a boiler
is not operating. The Condens 7000 WP incorporates a flue safety sensor which
monitors the non-return valve is fully shut. If the non-return valve does not
shut completely, the flue sensor activates the boiler fan and creates an alarm
to maintain safety.
The over pressure non-return valve comes as standard with our Condens 7000 WP
125kW and 145kW range.

Boiler room safety
CO sensors for cascade flue systems Bosch has taken the decision to require
the mandatory use of CO detection for boiler systems using cascade flue
systems, such as the 7000 WP, where there is more than one appliance
connected. This is to reflect state of the art in the industry and will help
to raise safety standards.
The base cascade flue kits now contain a CO detector for use in the
installation. For third party cascade flue system, a CO detector that is
interlocked with the boilers will be required. A suitable CO detector is
available as an accessory.
Part Numbers: CO Detector – 7-736-606-211 CO-Detector & Cut-off module set –
7-736-606-214
Typical use cases
The Condens 7000 WP has been developed to allow specifiers and heating
engineers greater flexibility to design heating systems, providing reliable
and efficient performance for any project.
The following hydraulic schematics show just some of the many options that are
available for individual and cascade installations.
Single boiler application
Single boiler applications are most commonly found in large domestic or light
commercial applications such as restaurants, churches and more.
Single boiler (heating + hot water)
AV P
Example shows: Single boiler is installed without a low loss header. If residual head is less than 200 mbar, on most instances you would not need an additional low loss header and system pumps. An RTH converter can be used to enable use of third party controls.
Single Boiler with plate heat exchanger (heating + hot water)
AV P
LS IV
NRV IV
Example shows: Single boiler is installed in an open vented system. The boiler can only operate in a sealed system. Where header tanks are used, you must install a plate heat exchanger (PHE). Alternatively a PHE is often used when system water is contaminated helping to protect the boiler.
Single boiler application 31
Single Boiler (heating only)
P
Example shows: Single boiler is used for heating only applications. For single circuit applications that require less than 200mbr, you can achieve this without the need for an additional low loss header or system pumps.
Single boiler with diverter valve (heating + hot water)
AV
MON_GE
P
Sense II
Example shows: Single boiler is installed in a sealed system. The boiler pump group has the 3 way valve (7-736-701881) fitted to enable the hot water to be diverted to either the central heating or domestic hot water tank. This example represents a system with 1 heating circuit and 1 DHW circuit. For further information on the controls shown go to page 20.
Single boiler with LLH (heating + hot water)
Sense II
2 x MM100
AV
Example shows: Single boiler is installed with a low loss header. Hydraulic break is required when adding additional system pumps to avoid running pumps in parallel. This example represents a system with 1 heating circuit and 1 DHW circuit. For further information on the controls shown go to page 20.

32 Single boiler application
Cascade application
It is important that a cascade controller is always used when cascading our
7000 WP boilers. The following examples show how this is achieved using either
the MC400 or 8313 controllers.
Cascade with LLH (heating + hot water) using MC400 cascade sequencer (BMS run
signal)
Example shows: Cascade system is installed with a low loss header providing
hydraulic separation from the rest of the heating system. This will ensure
that flow volumes are balanced and hydraulic performance is optimised. Cascade
control sequencing is achieved through the MC400 module rotating the lead
boiler for consistency and switching boilers on to meet varying demand. The
MC400 can be used with a BMS system where the MC400 controls the sequencing
strategy.

Example shows: Cascade system is installed with a low loss header providing
hydraulic separation from the rest of the heating system. This will ensure
that flow volumes are balanced and hydraulic performance is optimised. Cascade
control and remote monitoring is achieved via the CC8313 control with function
modules. The CC8313 enables internet connection, remote monitoring and
diagnostics complying with Part L building regulations.

Boiler configurations Cascade with plate heat exchanger or low loss header
A plate heat exchanger can be used to separate the boiler from the system in both open vented and sealed systems. This provides greater protection for the boiler, especially where the water quality in the existing system is poor.
A low loss header is a device that hydraulically separates the boiler from the heating circuit. This helps to improve the efficiency and performance of the heating system by regulating the pressure and flow rate of the system.
