The abstract for a study comparing three heating systems in a grow-finish room for electricity and natural gas use, pig performance, and air quality. The systems tested were a heat recovery ventilator (HVA), a ground source heat pump (GSHP), and a conventional forced-air convection heater. The HVA and GSHP provided an overall energy saving of 52% and 39% respectively, and had no impact on animal performance, even though feed intake was lower. The study was conducted for three winter months, and additional trials will need to be performed.
