Capacity tables - 1 Heating capacity tables Domestic hot water tank DOMESTIC HOT WATER TANK EKHWS The ALTHERMA by Daikin heat-pump in combination with the optional domestic hot water tank provide hot water for household usage. The below mentioned date allow a proper selection of the domestic hot water tank size for maximum comfort and efficiency. (1) Sanitary hot water volume: The volume of hot water available for domestic sanitary usage depends on the physical volume of the sanitary tank, on the sanitary water setpoint temperature and on the temperature spreading in the tank. Therefor we define the equivalent hot water volume (EHWV). Definition: EHWV = the volume of hot water available for domestic sanitary usage at a temperature of 40 C. 40 C is considered a comfortable sanitary hot water temperature. Tank Setpoint temp. Usage pattern EHWV (l) ( C) Modest Medium High 55 110 - - - 150L 65 150 + - - 75 175 ++ + - 55 160 + - - 200L 65 200 ++ + - 75 240 ++ ++ - 55 295 ++ ++ - 00L 65 85 ++ ++ + 75 45 ++ ++ ++ Grade ++ Excessive availability of sanitary hot water. + Sufficient availability of sanitary hot water. - Temporary shortage of sanitary hot water can occur. Usage pattern Modest Daily demand up tp 220 l -> typcial 2-persons usage pattern. Medium Daily demand up to 25 l -> typical to 4 persons usage pattern. High Daily demand up to 550 l -> 4 to 6 persons usage pattern. (2) Heat-up time: Definition: Heat-up time The time required to reheat the domestic hot water tank to 55 C after tapping a certain volume of hot water at 40 C. note: changing the field settings (see installation manual) can influence the heat-up time. Tank Setpoint temp. Heat-up time for 150 L (bath) Heat-up time for 50 L (shower) ( C) <min> <min> 150L 55 60 45 200L 55 60 40 00L 55 50 0 Conditions for testing: Ta = 7 CDB / 6 CWB, Troom = 20 C, Tstart = 10 C, outdoor unit type: ERYQ007 () Efficiency of sanitary hot water production: In the ALTHERMA by Daikin system both the heat-pump and the electric booster heater supply the energy to produce sanitary hot water. The higher the portion of energy supplied by the heat-pump, the more energy efficient the system is. Lowering the setpoint temperature increases the portion of energy supplied by the heat-pump and thus the efficiency of the system. Definition: Heat-pump portion Percentage of energy supplied by the heat-pump in the total energy need for sanitary hot water. Heat-pump portion Setpoint temp. ( C) Conditions: Real life condition Simulation of a daily usage based upon medium usage pattern. Outdoor temperature 7 CDB / 6 CWB Room temperature 20 CDB Outdoor unit type ERYQ007 Tank type 200l Field settings Default field settings (see installation manual). 4TW5789-1 70 Altherma Domestic hot water tank
