“…Heat transition is crucial for achieving EU climate targets. The European Commission has a recognized Energy Roadmap 2050 that electric heating can reach a share of 36-39% contribution to heat decarbonisation in 2050 [10] and heat pump technology seems to be the most appealing technology due to its high efficiency and profitability [11]. Moreover, heating demand is expected to decrease, while cooling demand is forecasted to increase [12] and one of the main strengths of heat pumps is their capability of generating both heating and cooling with the same device.…”

In the European Union, 40% of the overall final energy consumption is attributable to the buildings sector. A reason for such data may be found considering that the great majority of the building stock is more than 40 years old. According to the European Commission, an interesting potential lies in the refurbishment of the building sector, and heat pump technology has been recognized as one of the most cost-effective solutions to tackle the environmental issue of this sector. Regarding heat pump technology, ground-source heat pumps (GSHPs) have been proven to be the most efficient solution on equal boundary conditions. Despite this, in most EU states’ markets, GSHPs hold only a small market share with respect to air-source heat pumps. In this paper, the state of art and possible future developments of GSHP technology have been reviewed together with a focus on the potential of such technology, most of all on the refurbishment of existing buildings, and on the obstacles to its spread. The state of art of borehole heat exchangers has been studied, focusing on the parameters characterizing the outside pipe and the pipe itself, i.e., pipe and grout materials. Moreover, an overview on the last developments involving refrigerants and secondary fluids is given. Finally, the design and control strategies of GSHPs have been reviewed.

“…Just transition pays attention to the fact that transition policies should not reinforce existing inequalities and vulnerabilities within society, whilst supporting economic and industrial transitions (Kortetmäki and Järvelä, 2021). The notion of just transition is more challenging in the domestic sector where transition policies could directly influence the health, comfort and behaviour of end-users (Abbasi et al, 2021;Sovacool et al, 2019). Alleviating societal risks such as reducing fuel poverty, improving thermal comfort and promoting pleasant residential districts, is crucial for driving just and sustainable transitions in the residential sector.…”

“…In this transition process, introduction of heat pumps is recognized as a very efficient solution for utilization of different low-temperature heat sources [3][4][5][6]. In addition, due to significant increase of RES utilization for electricity generation, implementation of electrically driven heat pumps in district heating systems should be one of the main mechanisms for decarbonization of heating energy sector [7][8][9]. However, finding a proper low-temperature heat source that can be utilized by heat pumps in densely populated urban areas is not easy.…”

Evaluation of the effects of wastewater heat pump integration into district heating systems by simulation

The integration of wastewater heat pumps (using purified water) in district heating systems is analyzed in this paper. The simulation procedure is proposed to analyze the impacts of stochasticity of purified water temperature and flow to heat pump integration and operation. The analysis includes calculation of the daily and seasonal coefficient of performance, as well as fossil fuel savings and CO2 emission reduction due to wastewater heat pump use. The proposed procedure is implemented for the case study in the city of Sabac (Serbia) and obtained results are discussed and evaluated. The historical data for two heating seasons was used for simulation. It was shown that the wastewater heat pump could provide 27-28% savings in fuel consumption, and 3.6-4.1% GHG emissions reduction, while the seasonal COP could be 4.2 - 4.3. Simulation based approach shows approximately 40% less savings of fuel consumption, compared to the approach based on the average values of heat pump input parameters.
