Noise Level - A noise level of 48 dB(A) was measured at 1 m from the water heater during a Noise Test
conducted to Standard GB/T 23137-2008 in a hemi-anechoic chamber of a test laboratory. The noise level
when installed may be higher due to sound reflections from adjacent walls and structures.
COP – The Coefficient of Performance (COP) for a heat pump is the ratio of how much useful heat it
produces for water heating to the power input into the water heater. The higher the COP number, the more
efficient the heat pump is. The actual COP of the product at any given time will be impacted by a number of
factors, including the ambient air and cold-water inlet temperatures at the place of installation and time of
day / season of operation.
The COP of 4.5 is the average value measured under test conditions with an ambient air temperature of
19˚C/15˚C (Dry Bulb/Wet Bulb) over the entire heat-up process, heating of the water from 11.5˚C to 60˚C
during water heater operation and a power supply of 240 V~ 50 Hz. The Heat Pump average heating
capacity in Watts and its water heating capacity in Litres / hour were calculated from the results of this test.
The heat pump water heater performance tests were conducted to AS/NZS 5125.1:2014.
Ambient Air Temperature & Humidity – The performance of a Heat Pump changes with ambient air
temperature, humidity and incoming water temperature. The warmer the air temperature and the higher the
Relative Humidity and the cooler the water temperature, then the higher is the heating rate of the heat pump.
Performance specifications stated in relation to the heat pump are measured at predefined conditions during
its testing.
Average Heating Capacity kW or Watts – This is how much heating power is put into the water during the
heating cycle. It is expressed as an average due to the changes in heating power from the refrigeration cycle
as the water is being heated and its temperature increases during the heating cycle.
