Settings to reduce consumption of electricity for heating of hot water during summer ? Vitocal 222G

[Ned1]

I belong heating system Vitocal 222G and Vitocel 100. Now is summer and system is working only for heating a hot water. Can you help me to find best settings. I see that first step is settings for day/ night working shedule. There are settings for water temperure in boiler - Top/Standart/Temperature 2. Also option -heating with electricity, Start optimisation, 1xDHW. Can you advice for optimal settings to reduce day consumption and increase night comsuption. 

Thank you in advance

Hello Ned,

the most important point to optimize the consumption is that the desired hot water temperature is not set as high. This should only be as high as you and your family can consume during normal showering. The lower the setpoint temperature, the lower the consumption.

If you need a higher temperature, for example, to fill your bathtub, you can use the 1x hot water function. You activate this approx. 20 - 30 minutes before. At a cheaper night rate, it is recommended to set the switching times for hot water in the night. Then you will notice at what times you need hot water during the day. Then you set the times accordingly.

Thank you very much indeed for advice. Just please, for your opinion about these settings:
1. DHW with electrical heating. When this option is recommended?
2. When make 24 hours working schedule - what option to choose - TOP / Standard or Temp 2
3. About Start and Stop Optimization - how is working ?
Regards

The electric heating for hot water preparation is needed if your heat pump can not reach the set value alone. In the 1x hot water function is heated to the value Temp 2. With TOP is switched off when the set temperature value is reached at the top of the boiler. "Standard" switches off when the temperature reaches the complete hot water tank. The return temperature sensor of the heat pump is used for this.

Which attitude is best for you depends on your personal comfort wishes. The activation of the hot water preparation takes place with each setting after the storage temperature sensor in the top of the hot water tank. For this, the current temperature must have fallen below the setpoint by the set hysteresis. On delivery this is set to 7K.
