The answer to the initial question is enthusiastically revealed by the family from small village in Slovenia to anyone troubled by this question. The family, consisting of 7 members, is indeed a substantial consumer of hot sanitary water corresponding to the number of its members. They annually consume approximately 104,400 liters of water, which amounts to around 280 liters per day. It’s not surprising that they often ran out of hot water.
Before deciding to install a sanitary heat pump in their residential house in northern Slovenia, they used a regular electric boiler to heat sanitary water. The electricity costs were high, and they spent around 1000 EUR annually just for heating sanitary water. This was an additional reason for the family to replace the inefficient boiler with a more modern, efficient, and environmentally friendly hot water heating system. They chose the ECO sanitary heat pump with a 300-liter tank.
