In air source heat pump system, how to make water temperature reach 80℃? Only choose different refrigerant and compressor ? How to evaluate COP, does it relative to rated hot water output volume? For example:
heating capacity: 34.5KW(120000btu)
COP:2.7
Rate hot water output volume: 560Liter/hour
rated power input: 12.8kw
rated current input: 25.2A
max power input: 17.3kw
max current input:34.1a

scroll compresor, R134a,

How about the COP:2.7, how about the rated hot water output volume:560l/h.low or high?

Thanks for your kindly suggestion.Have a good day.
