Preliminary results show that the total thermal energy recovered was 259,425.63 kWh. The energy efficiency could be improved; In the first six months of measurements, per kWh of consumed electrical energy 33.11 times more thermal energy could be recovered (COP = coefficient of performance).
The recovered thermal energy can reduce the consumption of liquid gas for heating the animal houses, which is associated with the generation of CO2 emissions. Thus, heat recovery cannot only lead to savings in heating costs for the farmer, but also have positive impact on the released CO2 emissions which affect global warming. For the mentioned period, heating costs could be reduced by 1.54 € per animal place and, in addition, 5.32 kg CO2 per animal place were saved.
