Software for district heating

State-of-the-art IT solutions for effective management of district heating systems, both in the area of district heating networks and heat production process.

Software for district heating

Our solutions make it possible to optimize the system by monitoring the operation of the district heating network in real time, forecasting heat demand, optimizing network operating parameters and the heat production process, which translates into time and cost savings.

Modern modeling of district heating networks would not be possible without modern computer tools. They allow managing large amounts of data, solving complex non-linear equations and visualizing the results in a clear way. The combination of computer systems and engineering expertise has made it possible to take a step forward in the development of modern district heating networks. This is because it has made it possible to save time, money and, most importantly, ensure safety through more efficient control of district heating networks.

The experience gained during implementations of tools for managing heat network operation and cooperation with external companies has enabled Kelvin to become a valued integrator of advanced tools for engineering analysis, real-time production planning and optimization of heat network operation on the Polish and foreign markets. The offered solutions provide a decision support system for dispatchers, analysts and management. They allow the operation of the district heating network in an optimal way and enable the company to run more efficiently.

Software modules


The Off-line module maps the district heating system in the form of a digital mathematical model.

It performs hydraulic and thermodynamic calculations in static simulation mode.

The program provides information about the thermodynamic parameters at each point of the district heating system.


The On-line module maps the district heating system in the form of a digital mathematical model.

In real mode, it automatically downloads selected measurement data from the SCADA system and periodically performs hydraulic and thermodynamic simulations.

As a result of the above calculations, the program provides full information about the current thermodynamic parameters at each point of the district heating network.
types of use



The Temperature Optimizer minimizes the cost of distributing thermal energy in the network by optimizing the supply temperature derived from generating units.

When optimizing the parameters of the heating medium, both changes in the demand for thermal energy, weather conditions, technical limitations, the schedule of operation of sources, and the cost of purchasing thermal energy and electricity are taken into account


The Pump Optimizer selects the optimal operating parameters of circulating pumps and network pumping stations, in order to minimize the cost of purchasing electricity.

When optimizing the pressure settings on the pumps, technical limitations of the network and pumps are taken into account, as well as the minimum disposable pressure that allows the correct operation of nodes.


The Production Optimizer optimizes the work schedule of generating units located in different areas of the district heating system.

The optimization criteria are:

maximization of profits from the sale of electricity in the energy market,

minimization of generation costs, Taking into account the technical limitations of the generating units,

delivery of the required amount of energy to the system.
