4. What is a Dual Purpose Water Heater
A Dual Purpose Water Heater is a unit that will provide both heating water for space heating and also potable domestic hot water for washing from a single unit without any additional controls required
Domestic hot water is given priority over the space heating, and is activated by flow through the domestic hot water system
DHW is “on demand” and continuous, it will be provided as long as the faucet is open
Once DHW call is completed the unit will revert to heating the house as required

5. What is a Dual Purpose Water Heater
It is not called a Boiler in North America unlike the rest of the world, this is because
It does not provide closed loop heating water at a temperature above 176 DegF
It does not have an ASME H stamp, therefore cannot be used in areas where this is a requirement
Internal Water Volume is less than 1 gallon
Therefore these units are certified by ANSI Z /CSA as a gas water heater

6. Who makes this unit?
DAESUNG CELTIC is a Korean Gas boiler manufacturer established in 1982 Joint investment agreement with Chaffoteaux et Maury
Annually they produce and supply over 150,000 gas boiler products to Korea and world wide market.
Currently selling product to North America,
China, Russia, and several CIS countries

Range 47,800 – 99,000 Btu/h
DPW-120
Range 47,800 – 120,000 Btu/h
Closed loop heating water temperature range DegF
DHW temperature setting DegF, 120, 130 and 140 DegF

10. DPW Model Features
Wet recuperative HX manufactured from Aluminum Alloy
Removes latent heat from the flue gas to increase efficiency
By product is condensate, which is drained away from the unit via the condensate siphon
Condensate is slightly acidic – PH level 5

11. DPW Model Features
Exhaust and Inlet vent connections for 3” diameter Schedule 40 PVC
Flue gas temperature, max 136 DegF
Max flue length 45ft equivalent, max 3 elbows
Vent termination included

12. DPW Model Features Components included include
Primary loop circulator provides flow for either the Primary loop or close coupled AHU
Closed loop expansion tank – similar in size to a 20 gallon normal expansion tank

13. DPW Model Features
Flow switch on DHW cold inlet connection detects flow in the DHW system > 0.7 GPM
3 Way valve energizes to direct heating loop flow through DHW HX
Unit fires to provide DHW at temperature selected until call is completed
Temperature sensor on DHW outlet measures water temperature – unit will modulate to maintain temperature

14. DPW Model Features
Microprocessor control provides accurate control of heating water temperature and all other operational and safety features of the unit
Dip switches can be used to set up unit for various option
3Amp fuses protect unit

15. DPW Model Features Unit controller included
Sets heating loop water temperature from 122 – 176DegF
Sets DHW temperature 98 – 114 DegF, 120, 130 or 140 DegF
Displays room temperature but is not a thermostat
Shows error codes and unit operation status

16. DPW Model Features Simple Zone wiring
Two wires are used to connect to an X – X or dry contact (zero voltage) on zone controller or switching relay
Once contact is closed unit will fire and provide heating loop water at temperature selected on controller
Zone wires

17. DPW Model Features Self Diagnostic
13 Specific error codes are displayed in the event of a fault occurring
Range from condensate overflow to overheat to low water level

18. DPW Model Features
Built in closed loop strainer, located on return connection to the unit
Built in Air eliminator for the closed loop system – HOWEVER always install an additional high quality air vent – Spirotherm at highest point in the system

19. DPW Model Features
Modulating gas Valve This allows turn down of capacity over 50% dependant on load in the systems
Spark ignition and rectification flame detection saves energy and provides safety should the unit not ignite

20. DPW Accessories
DHW Tank – Storage tank to provide additional DHW performance for high DHW water demand applications
Buffer tank – Prevents short cycling of the heating system
LP Conversion kits to allow the unit to be field converted to LP gas supply

21. DPW + DHW Storage Tank Specifically designed for use with DPW
Available in a 20 Gallon Size
Combines the continuous use of an On Demand DHW supply with the flow rate and instant hot water of a tank, allows for use of Jacuzzi tubs etc
Design allows tank to be completely depleted for a tub, but still provides hot water if a shower is taken immediately after

22. DHW Storage Tank Supplied with for field installation
Taco 008 Pump Assembly with internal flow check
Mixing Valve
Pressure Relief Valve
Tank Drain
Aquastat to control tank temperature

23. DPW & TC-001 Conversion kit for gas/electric tank water heaters
All component parts needed to turn them into a QSDHS system including
Mixing Valve
Bronze pump with integral flow check

24. DPW & Buffer Tank 20 Gallon Buffer Tank
Used to prevent short cycling of the unit during mild temperature operation or if smaller zones than 20,000 Btu/h heat loss are used
Complete with all ports required and an aqua stat to provide a control input for the DPW, and maintain the set tank temp

25. DPW & LP LP Kit for field conversion
Unit specific, changes Nozzle assembly
Will require use of a manometer to adjust gas pressures to correct settings
