About me
The interest to monitor the temperature of our heating system started when our block power station could not reliably supply hot water for the handover station in the house for 130 households. This had the disadvantage that our hot water reservoir was not heated but rather cooled. I wanted to detect when the block power station no longer delivers warm water. I’m a professional software developer, so that shouldn’t be a problem. The block power station now operates without any failures. Now i have a system that measures and logs 11 temperature sensors. I can analyse the temperature with the android IoT Sensor Data. Through the analysis, I had set heating times differently for the used water and realized that our hot water tank loses too much heat, which is not due to any unwanted circulation, but because it can be better insulated. That’s what I’m going to do next.
11 sensors are connected:
- Block power station forward flow
- Block power station back flow
- Heating forward flow
- Heating back flow
- Hot water forward flow
- Hot water back flow
- Hot water charging forward flow
- Hot water charging back flow
- Hot water tank cold water suply
- Hot water tank temperature
- Room temperature
Isolation
Meanwhile, the storage is insulated and edged with MDF panels.
After isolating and lowering the hot water temperature to 53 degrees, the storage only loses 4.4 degrees in 24 hours. That should bring according to my calculations about 31 euros saving a year.
