Revision 3
Read this information in conjunction with Bosch Continuous Flow
Gas Heaters Installation & User Handbook, and pump manufacturers
operating instructions handbook.
•
The Accumulator design has exceptional thermal insulation to
meet Australian Standard AS 1056, and the gas units have no heat
loss when burners are off. As a result, this system is highly efficient
with almost no "standing or waste" heat losses and of course
absolute minimum heat wastage in storage to meet peak use.
The Bosch-Everlast™COMBO Commercial Gas Hot Water System
is a combined Gas Continuous Flow water heating system and
accumulator. The system has been manufactured to Australian
Standards AG 102 and AS 1056.
•
Modular design. The Everlast C2 Accumulator, the Bosch
Continuous Flow units and the Circulating Pump such as Davey
SB30-25 & Grundfos 32-80B; are ALL separate components and are
independently serviced for replacement or repair. No unitary system
high replacement costs.
Bosch - Everlast™COMBO Gas Hot Water System
The system incorporates a full copper heat exchanger for maximum
life and a premium marine grade 316 stainless steel cylinder. The
system is covered by a 10 year warranty in domestic installations,
and 5 year warranty in commercial installations; as per the enclosed
warranty conditions.
The combination of the high efficiency and powerful Bosch
Continuous Flow hot water heaters with the durable, highly
insulated Everlast C2 Accumulator, yields a high delivery, very long
life hot water system.
The system can be sized to meet applications where far more
expensive options would be the only other design alternatives.
Features of your Bosch - Everlast™ COMBO Water Heating
System
• This system provides both flow and temperature buffering from a
250 or 315 litre Accumulator so that high peak hot water draw-offs
and high average peak flows do not result in flow or temperature
fluctuations. (Actual capacities of Accumulators exceed the rated
sizes by about 20 litres).
• Systems with an Accumulator deliver stability under peak
demand extremes without the need to over design a non
accumulator system.
• Multiple Bosch Continuous Flow units may be manifolded to the
Everlast Accumulator with No need for Staging of the Cold Water
Supply Inflow, as the Total flow of the manifolded units has to be
circulated through the Accumulator to ensure best buffering and
recovery performance.
•
50 mm primary flow fittings oriented for commercial manifolding
with a minimum of coupling tees or size change socket fittings.
•
Technical Support. Available from Everlast, to assist you in
design, component selection and specification. Bosch Continuous
Flow manufacturers technical service will provide system information
on units, performance and flueing options for internal units and hot
water accessories.
The Bosch-Everlast™COMBO Water Heating System uses Bosch
Continuous Flow water heaters typically from 132 – 200 MJ/hour.
Multiple Bosch units can be manifolded together with one Everlast C2
Accumulator. When a Single Bosch unit is required an Accumulator is
available with integrated mounting points and with the addition of the
Pipe cover, a space saving, secure and aesthetic package is
presented. As a design example :
A COMPLEX OF TWENTY-FIVE 3 BEDROOM APARTMENTS
INCLUDING ENSUITES IS FULLY SERVICED BY THREE 200
MJ/HR MODEL 25 E HEATERS & TWO 315 L C2
ACCUMULATORS.
" COMBO " Water Heating System
There are three main water "circuits" in the Bosch-Everlast COMBO
Water Heating System :
a) The "Mains Pressure" Circuit - causes water to flow from the
'mains supply' to the Accumulator cylinder and from the Accumulator
cylinder to the system outlets. Diagram 1 shows the "Mains Pressure"
circuit.
C:\Documents and Settings\Matt\My Documents\Business\everlast\content\commerical_315C250_MANUALandWarranty.doc Page 2 of 12
January, 2006
Revision 3
The "Primary Circulation" Circuit - causes water to flow through the gas
heating process. The Primary Circulation Pump sources its water from
the Accumulator cylinder or the mains supply or both.
(This will depend on the flow rate through the mains pressure circuit).
Because heated water is always discharged to the Accumulator the
delivered temperature is very stable. Diagram 2 shows the Mains
Pressure + Primary circuits.
b) The "Secondary Circulation" Circuit (this is only required where
there is a need for secondary pipework reticulation i.e. hot water flow
is maintained in a loop through all outlets). In these installations the
secondary return is connected to the hot water primary flow pipe to
ensure the hot water that is circulating does not short circuit the mix
into heated water. Diagram 3 shows the Mains Pressure + Primary +
Secondary circuits.
Notes for the following Water flow circuit diagrams :
Applications
In applications where hot water supply is direct and non-recirculated,
such as some motels, laundrettes, hospitals and sports club
showers; the mains pressure and primary circuits provide a simple
system capable of very high delivery and heat transfer.
In applications where hot water is to be circulated past the outlets,
such as some motels, apartments and very large homes; the
secondary circulating pump and circuit provides immediate hot water
delivery at each outlet with this minor addition to the system. Usually
made in-situ, this circuit is additional to the Integrated Package and is
not provided in the Bosch-Everlast Integrated Package.
Tempering or Thermostatic mixing valves
In accordance with Australian Standard AS 3500.4, it is
recommended that where required a temperature control device or
mixing valve be fitted between the water heater and bathrooms and
ensuites to reduce the risk of scalding. This is achieved by
controlling water temperature to below 50 degrees C. The locations
as shown on the Water flow circuit diagrams are where required at
point of use in the mains pressure circuit.
To ensure there is no conflict with thermostat set temperature of
the COMBO system, they are not associated with the primary or
secondary circulation circuits.
Expansion Relief Valve.
A 750 – 850 kPa expansion relief valve is recommended in the
Primary Circulation Circuit which is transferring heated water into
the Accumulator. The valve allows for expansion of water in the
primary piping loop during the heating cycle. Discharge may
occur during heating and is normal.
Pressure and temperature relief valve (PTR)
A Pressure Relief Valve is located on the Hot Water Outlet
connection of each Bosch Heater Unit in accordance with AG
102, to prevent pressure damage to the heat exchanger.
The COMBO Accumulator cylinder features dual 20 mm PTR
ports. Two 850 kPa PTR valves are provided to meet
requirements in accordance with AG 102 Sec 2.7.10. State
Regulations may require the installation of two PTR valves and/or
PTR valves in the piping manifold configuration. If only one PTR
valve is required, the second provides safe redundancy or a
blanking plug may be substituted. The PTR valve pressure
setting should always be 850 kPa.
Pressure limiting valve
A 500 - 600 kPa Pressure Limiting valve must be fitted, to
ensure correct function of the system in conjunction with
the PTR valve / Expansion Relief valve.
As shown in the Water Flow Circuit Diagrams, isolating valves for
ease of service, line strainers and non return valves are
recommended as good installation practice and to ensure
protection of pumps from contamination or damage in the event
of water system pick up of contaminants.
Installation must comply with Australian Standard AS 3500.4 National Plumbing Code, and any local authority regulations.

** Notes for tables: Motel rooms will be a mixture of 1 bedrooms
with 1 or 2 people showering (business accom. is typically 1 person);
and 2 bedrooms with 2 or 3 persons showering. Therefore to average
at 2 persons per room is conservative, safe design.
These are scenarios ranging from small motel/hotel/unit
developments up to significant multi room accommodation; serviced
with very efficient hot water plant .
3 Star Accommodation equals 30 Litres per person per Peak Hour
5 Star Accommodation equals 45 Litres per person per Peak Hour
The 50 mm sizing of Primary Circulation piping in the COMBO
design, ensures that the system will meet the range of major
commercial applications of single or multiple Gas units; manifolded to
the COMBO. Connection may be made using 50 mm direct coupling
as required. The factors to be considered by the Installer are the
mains supply piping/flow rates, and Secondary Circuit piping, if
required.
The following design principles should be considered in the
determination of the mains and secondary piping sizes :
If pipework is undersized for the required flow (litres/sec) or
(litres/min), then the velocity will increase (metres/sec) resulting in an
increased pressure loss. If pipework is oversized for the required
flow, then the heat loss will be increased.

The Bosch Continuous Flow Water Heater Manuals available from
Robert Bosch Australia; and the publication "Selection and Sizing of
Copper tubes for water piping Systems" by B. Smith, available from
Copper & Brass Information Centre, or Institute of Plumbing Australia;
are helpful publications.
Whilst major systems do require the input of competent hot water
system designers, the application of the Guidelines in the above
publications and particularly the Guidelines for Installation in the
Bosch Continuous Flow Water Heater Manuals will facilitate good
design in respect to Pipework.

These Davey & Grundfos pumps are multi speed pumps where pump speed
may be matched to system design (see above). They have a bronze body
and brass connections. Refer to the Davey & Grundfos Pump Manuals for
single speed and Secondary Piping Circulator pump alternatives.
Internal Installation Water Safety
For internal (indoor) installations of Accumulator, a safe tray is
recommended in accordance with Australian Standard AS 3500.4
This is necessary to prevent damage associated with a leaking pump
or fittings, or when flushing the Accumulator.
Secondary Circulating Pump and Pipework
The secondary circulating pump and pipework (where required) will
always be sized to produce the flow rate that has been determined
from system heat losses and draw off's that provides acceptable
temperature drop before return.
The Davey SB30-25 multi speed pump may be utilised for secondary
circulation, or when secondary pipework is 25 mm or 18 mm, the
SB25-20 or Grundfos equivalent may be preferable such as the UPS
25-40B, UPS 25-60B & UP 25-80B. Flow characteristics to suit the
system may be selected from the manufacturers Circulator Pumps
Handbooks. These handbooks incorporate flow curves for each pump
which may be relied upon to suit the hot water circulation
requirements of the system.
Electrical Connection & Wiring
The Bosch-Everlast™COMBO Commercial Gas Hot Water System is
designed for single phase 240 V. A.C. supply only. Australian
Standard AS 3000 – (Wiring Code), and local supply authority
regulations apply.
Notes for the following Schematic Wiring Plans :
240 V AC Supply is required at the point of connection of the
Accumulator Thermostat for the operation of the Primary Circulating
Pump. Where a Secondary Circulating Pump is required, the AC
supply to this pump must be located in close proximity to the pump.
Connection is made at the terminal location points under the IP rated
weatherproof thermostat cover. Wiring entry to the connection point is
made through the blanked-off standard conduit port adjacent to the
thermostat cover, by removal of the blanking plug. Always install a
standard 20 mm conduit elbow to the port to ensure conduit support.
240 V AC Supply may be required at the point of connection of the
Gas Continuous Flow Water Heater(s) to energise the electronic
burner ignition system.
High Temperature Hot Water Applications are referred to the further
schematic for the high temperature thermostat, and the notes therein.
