By connecting the set of coil with heat pump directly, the safety of sanitary hot water inside the tank, is also
ensured.
However, the capacity of the coil should be bigger than the maximum output of the unit (heat pump output
at A7/W45). Usually this solution is used for working together with a heat pump whose capacity is less than
14kW.
The advantage of this application is that it can supply bigger volume of hot sanitary hot water.
The disadvantage of this application is that this coil may create big water flow resistance to heat pump water
circuit. Thus it may need to add a secondary water pump to ensure the flow rate of heat pump unit.
Otherwise it may affect unit efficiency or make the unit work improperly
