1. Hot water demand To understand their needs, how much hot water is needed. High temperature heat pumps can produce up to 85 ℃ of hot water, but in general can also maintain 65 ℃ hot water.
2. Energy Efficiency ratio Look at the energy efficiency ratio of the high temperature heat pump of your choice. It is understood that the current high temperature heat pump to do the best energy efficiency than about 3.6.
3. Ambient temperature The ambient temperature of the area where the unit is located needs to be considered. If the unit needs years to make high-temperature heat pump hot water, need and supply manufacturers special instructions.
