Introduction
Thanks for choosing OptiTech air source heat pump for your hot water. Please read this
manual carefully before installation and operation.
Working Principle
The heat pump water heater system heats water by transferring the heat from the
surrounding air to the water using a refrigerant. The refrigerant is heated by a heat
exchanger that absorbs heat from the surrounding air (Figure 1).
Note:
The unit must have a minimum of 5 hours continuous power available at all times to allow
the unit to operate without affecting reliability.
