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) Domestic hot water volume:
The volume of hot water available for domestic usage depends on the physical volume of the tank, on the domestic water setpoint temperature and on the temperature spreading
in the tank.
Therefore we define the equivalent hot water volume (EHWV).
Definition:
EHWV = the volume of hot water available for domestic usage at a temperature of 40°C.
40°C is considered a comfortable domestic hot water temperature.

Usage pattern
Modest
Daily demand up tp 220 l -> typcial 2-persons usage pattern.
Medium
Daily demand up to 325 l -> typical 3 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.

Conditions for testing: Ta = 7°CDB / 6°CWB, Troom = 20°C, Tstart = 10°C, outdoor unit type: ERHQ008
(3) Efficiency of domestic hot water production:
In the ALTHERMA by Daikin system both the heat pump and the electric booster heater supply the energy to produce domestic 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 domestic hot water.
