5kW R410a Ecodan PUHZ-W50VHA2(-BS) maximum output testing

Test 3

  • Outside temperature back of the unit 0.84C
  • Metoffice: 0.7C
  • Metoffice dew point: -1.3C
  • Metoffice relative humidity: 87%
  • Average heat output 4.57 kW

The datasheet suggests that capacity should be 5 kW at 2C ambient and 4.5 kW at -7, so about 4.94 kW at 0.84C. So ~7.5% less than the data sheet output in this test.

  • 1st cycle: 4.4 kW, outside temp 0.86C
  • 2nd cycle: 4.5 kW, outside temp 0.27C
  • 3rd cycle: 4.8 kW, outside temp 1.34C
