Carbon Dioxide Emissions from a Ground Heat Pump for a Detached House

Sara Sewastianik , Andrzej Gajewski


Inasmuch as the European Union promotes only energetically viable heat pumps in a given location, the aim of the work is an assessment of whether a ground-to-water heat pump (ground source heat pump: GSHP) can be considered as an ecological heat generator in Polish climatic conditions and those of the energy market. Here, as an estimator, the net seasonal coefficient of performance (SCOPnet) was selected. Estimation was done using 10-year temperature measurements. It was found that in heating mode SCOPnet value equaled 4.83, satisfying European Commission guidelines. According to the guidelines, the minimal SCOPnet value in Polish energy market conditions should exceed 3.5. CO2 emissions from the GSHP represented two-thirds of CO2 emissions of an air-to-water heat pump (air source heat pump: ASHP) in the same building. The ground heat pump thus meets the ecological heat generator conditions set by the European Commission.
