Altherma HT-TW Domestic hot water tank
The DAIKIN ALTHERMA 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) Capacity:
EKHTS*200 EKHTS*260
Total capacity (L) 210 258
Actual capacity (L) 193,5 250,5
Total capacity = internal volume of tank(= effective water volume+ coil volume)
Actual capacity=effective water volume inside the tank
(2) Maximum volume of usable hot water:
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.
Definition:
Maximum volume of usable hot water = 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. (cold water inlet temp = 10°C)
Tank
Setpoint temp.

Grade +++ more than excessive availability of sanitary hot water (more than 40% of EHWV is still available after tapping pattern)
++ Excessive availability of sanitary hot water. (10%< EHWV still available after tapping pattern<40%)
+
Sufficient availability of sanitary hot water.
(EHWV still available after tapping pattern <10%)
- Temporary shortage of sanitary hot water can occur.
Tapping pattern** Small Daily demand up to 90l -> typical 1-person daily usage pattern
Medium Daily demand up to 190l -> typical 2-persons daily usage pattern
High Daily demand up to 370l -> typical 3 to 4 persons daily usage pattern
very high Daily demand up to 500l -> 5 to 6 persons daily usage pattern
* based upon heat up to tank once / 24 hours
** Heat losses (over 24 hrs) are included in the tapping patterns
(3) Standing Heat loss:
Tank

[kWh/24h]
EKHTS*200 1.2
EKHTS*260 1.5
* heat loss of tank at_T = 45K
(4) Heat-up time:
Definition:
Heat-up time = The time is required to heat up the domestic hot water tank from 15°C to 60°C (minutes)
Tank

EKHTS*260 70 60 50
conditions for testing: Ta = 7°CDB / 6°CWB, TStart = 15°C
(5) Reheat time:
Definition:
Reheat time = The time required to reheat the deomestic hot water tank back to 60°C after tapping 70% of the actual volume.
Tank
Reheat time <min>
