Allows you to reduce water flow to the heat pump as it is not designed for high flow rates and takes time to heat the water.
The bypass branches off part of the pool water, directs it through the heat pump for heating and returns the heated water back to the normal water circuit.
For integrating a heat pump into the filter circuit of a pool.
Direct integration of the heat pump into the main circuit is not possible as it always relies on the support of the filter system to move the water.
By using the bypass set, the heat pump can work efficiently without affecting the main water circulation, thus ensuring even heating of the pool water.
