The system delivered 147,133 megajoules of heat while using 38,917 megajoules of electricity, which works out to a seasonal performance factor of 3.78, and the team says most of that electricity use can be covered by the rooftop solar unit.<\/p>\n\n\n\n
Why barn heating is suddenly a bigger deal<\/h2>\n\n\n\n
In pig farming, the stakes are simple. Temperature and humidity have to stay in a tight band for animal health and growth, especially in nursery buildings, and the HVAC equipment that makes that happen can be energy hungry and emissions heavy when it runs on fossil fuels.<\/p>\n\n\n\n

Fuel price swings, grid constraints<\/a>, and cold snaps can turn heating from a routine cost into a painful surprise. That is why projects like the EU-backed RES4LIVE program have been testing \u201cfarm fit\u201d renewable systems that aim to cut fossil use without sacrificing animal comfort.<\/p>\n\n\n\nThe three technologies doing the heavy lifting<\/h2>\n\n\n\n
The Italian prototype stacks three tools that are each useful on their own, but more interesting together. Photovoltaic thermal (PVT) collectors make electricity and harvest heat at the same time, a borehole thermal energy storage field (BTES) banks some of that heat underground<\/a>, and a 35-kW dual-source heat pump can pull heat from the ground or the air depending on conditions.<\/p>\n\n\n\nIn the test setup, that meant 24 roof-mounted PVT collectors, eight boreholes about 30 meters deep (roughly 98 feet), and a control station that manages the energy flows.<\/p>\n\n\n\n
The control layer is not a footnote, it is the system. The heat pump was centrally managed via PLC automation, supply water was kept around 50\u00b0 to 55\u00b0 C (about 122\u00b0 to 131\u00b0 F), and the whole setup was monitored through a cloud-based platform so temperatures, pressures, and performance could be tracked in real time.<\/p>\n\n\n\n
The performance numbers that make this more than a demo<\/h2>\n\n\n\n
On the farm, the old baseline was familiar across agriculture. A 34-kW LPG boiler handled the nursery building, with thermal lamps in each room doing backup duty.<\/p>\n\n\n\n
During the first monitoring year, the hybrid system delivered 147,133 MJ of heat (about 40.9 MWh) while consuming 38,917 MJ of electricity (about 10.8 MWh), and the reported average coefficient of performance was about 4.07, with the heat pump running mostly from November through April and a defrosting rate of 3.6%. <\/p>\n\n\n\n
