Energy extracted from the earth's interior serves a dual purpose: it ensures both comfortable building heating and constant access to domestic hot water.
Geothermal heat thus becomes an invisible but essential element of daily life in Stargard, servicing residential buildings and public utility facilities. The entire distribution system relies on precise transmission logistics – water must reach the furthest points of the city while maintaining appropriate parameters.
What happens next? Water that has given up its energy in radiators or hot water exchangers cools down and returns to the PEC plant and Geotermia Stargard mining facility, where it is reheated and put back into circulation.
It is worth emphasizing that throughout the year, the potential of our reservoirs is utilized at full achievable capacity – and in the non-heating period, it is Geotermia Stargard alone that covers the city's full demand for domestic hot water. Thanks to this, for several months of the year, residents benefit exclusively from ecological energy flowing from the earth's interior.
The lifecycle of district heat in Stargard can be described in three steps:
- Supply: Hot water reaches heating substations in buildings via pipelines.
- Consumption: Energy is transferred to internal installations (radiators and taps), and the network water loses temperature.
- Return: Cooled water returns via return pipes to the PEC and Geotermia infrastructure.
There, a renewed meeting with hot brine in heat exchangers awaits it, and the whole process begins anew. It is an ecological and economical cycle that makes Stargard effectively use natural resources.
