  • Page 10 Water Piping Limitations Design the water pipe length within the QH characteristics of the pump (flow-rate and pump head). The maximum height difference for the water pipes is 7 metres. Piping to hot water tank (option Water supplied to the hot water cylinder is branched by a motorized 3-way valve (procured locally). Connect the hot water cylinder to port A (open when energized) of the valve.
  • Page 11 Checking water volume and initial pressure of expansion vessel The expansion vessel of the Hydro Unit has a capacity of 12 litres. The initial pressure of the expansion vessel is 0.1 MPa (1 bar). The pressure of the safety valve is 0.3 MPa (3 bar). Verify whether the capacity of the expansion vessel is sufficient using the following expression.
