17.12.2015

The following data presented here is taken from a household air-to-water heat pump which is connected to the optimization service. The period covers from 17.Oct – 17.Dec 2015.

Environment details
Type Private household
Floor size 105 m2
 Heating Air-to-water heatpump – 3 kW
Inside and outside temperature
min max
Temperature outside 2,3 oC 5,2 oC
Temperature inside 19,8 oC 23,1 oC
Power Consumption
24 hours 15 kWh
Month 606,1 kWh
Electricity Cost
Optimized Cost Average Cost
Day 0,396 € 0,545 €
Month 11,88 € 16,35 €

Compared to weighted average of the normal electricity cost or against the fixed tariff, the cost saving is  27.4 %

Transmission Cost
