What is X-Flow?

X-flow is a state-of-the-art fresh water ultra-tank produced by Calpak, which is able to achieve 99% heat exchange efficiency using patented  heat transfer technology. This extremely high efficiency can allow the user to save 25% of their energy usage when compared to conventional tanks.

All water supply sources are applicable for the X-flow tank whether using boilers, heat pumps or solar water heaters or anything other hot water source. Using an advanced counter-flow mechanism, X-flow is able to achieve an impressive temperature difference of only 1°C at the outlet of the tank. This minimizes the energy waste and allows you to save on energy costs.

X-flow is available in multiple tank capacities of 500L up to 2000L, and is capable of handling outflows of 1500 L/h, 3000 L/h and 4500 L/h.
