Our heating monitoring system gives you complete insight into your installation, reduces your energy costs and increases reliability.
Ensuring the safe, efficient and compliant operation of a building's heating system is a major responsibility. These installations are often complex and consist of multiple heat sources that work closely together. Without continuous insight, malfunctions or waste can occur unnoticed, resulting in higher costs, additional energy consumption and possible complaints from residents or users.
That is why it is crucial to continuously monitor all key data, including temperature, pressure, pump status, burner capacity and energy consumption. This makes deviations immediately visible and allows timely measures to be taken, even remotely.
With Energy System Monitoring, ista makes the energy system fully transparent and controllable. Intelligent sensors record all important measurement points in the boiler room. This data is continuously transmitted digitally and is available in real time.
All information is gathered on a single central platform, where it is analysed, visualised and checked against pre-set limits. Any deviations – such as excessive energy consumption or a fault signal – are immediately reported. This allows managers or installers to intervene quickly and prevent unnecessary costs or damage.
You have a complete overview of your installation at all times. This allows you to plan maintenance proactively, carry out targeted optimisations and take advantage of all opportunities for energy savings. In this way, ista increases the reliability of your systems, reduces your costs and contributes to CO₂ reduction.
The online ReduQ portal is your central access point to all boiler room data. Measurements from sensors and meters are clearly presented in dashboards and interactive graphs, providing immediate insight into temperature, pressure, consumption and efficiency.
You monitor trends, generate reports and set limit values. In the event of deviations, you will automatically receive notifications by text message or email, enabling you to take swift action. This makes boiler room management simple, transparent and reliable.
