New Zealand has a power supply of 230volts, 50hz, single phase. “Can Geothermal Systems run on that power supply”?
Geothermal Systems are designed to run on either 230, 60hz, single phase or 230 ,50hz, single phase. The systems will run on either frequency, however when purchased for 230, 50hz the outputs are re-rated to reflect the slower speed. The re-rating means that we would down grade the output by 17 to 18%, but the efficiency is increased because we are running larger compressors at a slower speed, thereby un-loading the system.
