The MULTIFUNC All-in-One multifunctional water tank is innovative, uses a patented design, is a new type of practical technology and makes FLIXX products more competitive in the market. Suitable for heat pumps of different capacities.
With the built-in three-way valve, the water tank can be easily matched with different heat pumps and avoid the heat pump unit from shutting down due to insufficient water flow when the load is low. This design not only extends the service life of the heat pump, but also ensures very stable operation and excellent performance.
The multifunctional water tank is connected to the bypass waterway, and its system includes the following key components:
- electric 3-way control valve
- buffer tank
- expansion tank.
Since it is a heat storage type water tank, it can be used for both home heating and hot water supply at the same time, meeting the different needs of users in every season.
