Yes, as Sensaru orchestrates all components in the boiler room — such as the heat pump, peak load boiler, and heating circuit pump — it ensures smooth and highly efficient operation.
Functions and system advantages
What functions does the Sensaru system offer?
What functions does the Sensaru system offer?
The system covers:
- Recording of flow temperature, heat quantity, gas consumption, water pressure, outside temperature and energy consumption
- Dynamic heating optimisation through AI-supported models
- Energy reporting and automated reporting (e.g. for ESG reporting and the EU Taxonomy)
- Support for heating inspections in accordance with §§ 60b and 71a GEG
How does the Sensaru system help detect heating system failures at an early stage?
How does the Sensaru system help detect heating system failures at an early stage?
Our cloud-based alarm system continuously monitors for typical fault patterns, such as falling water pressure, faulty hot water production, and deviations in flow temperature. As soon as a critical condition is detected, an alarm message is automatically generated. This message can be configured individually and is forwarded directly to the relevant teams.
What role does artificial intelligence (AI) play in heating optimisation with Sensaru?
What role does artificial intelligence (AI) play in heating optimisation with Sensaru?
Our pre-trained AI models analyse sensor data continuously and control the heating system dynamically, adapting it to weather conditions, building usage and actual heat demand. This permanently reduces energy consumption and CO₂ emissions, ensuring economical operation.
What sets the Sensaru Cloud apart from other systems?
What sets the Sensaru Cloud apart from other systems?
Unlike other systems, our cloud offers traditional monitoring as well as combining monitoring, reporting, alerting and AI-supported heating optimisation on a single platform. This enables you to comply with legal requirements, support your ESG goals and streamline operational processes with no extra effort.
What advantages does the system offer for ESG reporting?

Through continuous data collection, Sensaru provides reliable measurements that can be used directly for ESG reporting and EU taxonomy-compliant reports – automatically and in a legally compliant manner.
Does the Sensaru system require existing building management technology?
Does the Sensaru system require existing building management technology?
No, as our system works completely independently of existing control systems. The sensors are quick to install, and connecting to the cloud is straightforward. This makes Sensaru ideal for retrofitting in existing buildings.
Does the Sensaru system meet the requirements for statutory remote monitoring?
Does the Sensaru system meet the requirements for statutory remote monitoring?
Our continuous measurement and monitoring eliminates the need for regular repeat tests, particularly for heat pump systems.
Energy savings and cost-effectiveness
