Question Typical water volume
How many showers are needed per
day? 1 shower = 10 min×10 l/min = 100 l
How many baths are needed per day? 1 bath = 150 l
How much water is needed at the
kitchen sink per day? 1 sink = 2 min×5 l/min = 10 l
Are there any other domestic hot water
needs? —
Example: If the DHW consumption of a family (4 persons) per day is as follows:
▪ 3 showers
▪ 1 bath
▪ 3 sink volumes
Then the DHW consumption = (3×100 l)+(1×150 l)+(3×10 l)=480 l

Possible DHW tank volumes
Type Possible volumes
Standalone DHW tank ▪ 150 l
▪ 180 l
▪ 200 l
▪ 250 l
▪ 300 l (polypropylene tank is
compatible with solar kit)
▪ 500 l (compatible with solar kit)
Energy saving tips
▪ If the DHW consumption differs from day to day, you can program a weekly
schedule with different desired DHW tank temperatures for each day.
