System integration of geothermal heat plant in high-temperature district heating system - technical and economic issues
The prefeasibility work covers two complementary sub-projects. Rooftop‑based solar district heating integration in existing district heating systems in Bucharest, Romania and a centralized solar thermal plant combined with thermal storage and auxiliary systems in Zaprešić, Croatia.
The SET-HEAT project webinar titled: ‘Current Actions for Decarbonisation of Croatian District Heating’ was held on 5 December 2025 on the MS Teams platform. It can be still watched on YouTube platform: https://youtu.be/xN0BfWLy53c
The SET_HEAT_CHP project concerns the deployment of an integrated hybrid heat‑recovery and heat‑pump system. The intervention targets low‑temperature (LT) and medium‑temperature (MT) waste‑heat streams originating from gas‑engine cogeneration units and couples them with high‑efficiency industrial heat pumps to increase the usable share of renewable and waste‑heat sources in district heat supply.
The document presents the technical pre-feasibility study for integrating air source heat pumps (ASHPs) and a 3,000 m³ thermal storage tank into the Naujoji Vilnia district heating (DH) system in Vilnius, Lithuania. The project supports the LIFE22-CET-SET_HEAT initiative aimed at accelerating energy transition and decarbonisation of district heating systems.
