IoT solution for monitoring district heating systems

District heating systems efficiently supply urban areas as well as residential and industrial complexes with heat, while IoT monitoring systems help to keep pressure and temperature in the optimum range. Double-walled pipes monitored with IoT sensors ensure the safe transport of high-temperature fluids and control vacuum loss to reduce energy costs and effectively maintain insulation.

Increasing efficiency in district heating systems through IoT and vacuum monitoring

A vacuum loss in the outer pipe leads to considerable heat losses. Pressure monitoring ensures that energy efficiency is maintained.

Monitoring the vacuum in double-walled pipes is an essential part of ensuring the efficiency of district heating systems. By quickly detecting pressure drops and leaks, the system can react immediately before significant energy losses occur. However, if leaks are not detected in time, this not only leads to high heat losses, but also to a steady increase in energy consumption as the system attempts to compensate for the pressure loss. This puts a strain on the infrastructure and can lead to long-term damage to the pipework, resulting in expensive repairs and unplanned downtime. In extreme cases, an undetected vacuum loss can even severely affect the overall efficiency of the district heating system, drastically increasing operating costs and worsening the environmental footprint. Regular monitoring prevents these negative effects and ensures the smooth operation of the system.

Focus on energy efficiency: How monitoring reduces the primary energy factor of district heating

Monitoring district heating systems offers numerous advantages by improving energy efficiency and recognising operational faults at an early stage. With the help of IoT sensors, pressure drops, leaks and material fatigue can be monitored in real time. This prevents heat loss and ensures that the district heating system operates efficiently and cost-effectively. Particularly in district heating networks based on waste heat utilisation or geothermal energy, monitoring ensures that the renewable energy is used optimally and the primary energy factor of the district heating is reduced.


Without regular monitoring, unnecessary, rigid inspections lead to high costs, such as personnel, difficult-to-access shafts and road closures. At the same time, inadequate monitoring harbours the risk of leaks not being detected, leading to significant energy losses and a reduction in energy efficiency. Real-time data transmission enables faster fault detection, improves maintenance processes and extends the service life of the infrastructure.


District heating monitoring therefore not only offers cost savings, but also more efficient utilisation of renewable energies and the opportunity to reduce CO2 emissions.

IoT for district heating: Efficient pressure monitoring can also be used for local heating networks

Local heating networks are smaller in scale and less complex than district heating systems, as they are usually confined to limited areas such as housing estates or industrial estates. The shorter distances mean that heat losses are lower compared to district heating networks, allowing the system to operate more efficiently by nature. However, even with local heating networks, pressure monitoring remains crucial to detect leaks and pressure losses at an early stage to ensure operational efficiency.


While district heating systems require a more extensive infrastructure and more complex monitoring, the monitoring of local heating networks requires fewer sensors and is easier to handle. Nevertheless, the implementation of IoT pressure sensors also enables precise and automated monitoring in local heating systems, which reduces maintenance effort and costs. Real-time monitoring means that pressure losses can be rectified immediately before major problems arise, increasing the efficiency and service life of the system.


In summary, local heating networks are cheaper to monitor as they have fewer infrastructure points and shorter pipework. Nevertheless, pressure monitoring remains essential to keep the system running smoothly and efficiently, similar to district heating systems, but with lower requirements for the complexity and scope of monitoring.

IoT solutions for efficient monitoring of district heating systems: who benefits? 

Municipal utilities and municipal companies

The monitoring of district heating systems is essential for municipal utilities and municipal companies in order to manage the heat supply in cities efficiently and cost-effectively. By digitally monitoring the networks, they can detect leaks at an early stage, optimise energy consumption and ensure even heat distribution. This is not only of great importance for security of supply, but also for achieving municipal sustainability goals.

Energy consultants and engineers

For energy consultants and engineers who want to offer their customers optimised solutions, the monitoring of district heating systems is an ideal complement to ensure the efficiency and reliability of heat supply infrastructures. They support their customers in making the operation of district heating systems more efficient. Through monitoring, they can make targeted recommendations on how to monitor the systems and recognise potential problems at an early stage, thereby reducing maintenance costs and ensuring a stable heat supply.

Industrial companies

Industrial companies benefit enormously from monitoring district heating systems, as they often generate large amounts of waste heat themselves, which can be utilised for district heating. Real-time monitoring allows them to ensure that this waste heat is optimally utilised and that energy efficiency is increased. Monitoring also helps to prevent breakdowns by detecting potential faults at an early stage, which reduces operating costs and improves the sustainability of the company.

Property management company

For housing associations, monitoring district heating systems is particularly advantageous for reducing operating costs. One of the main factors is the cost of manually reading meters and heat consumption values in large building complexes. By implementing IoT monitoring systems, this data can be automatically collected and transmitted in real time, eliminating the need for expensive meter readings. This not only leads to savings, but also to more efficient billing and improved transparency for tenants.​
