Multi-Energy OptionsA Primary thermal storeB Stainless steel DHW tankC Heat source from solidfuel boilers or heat pumpsD Coil heat exchangerE Immersion heaterF Heat source from solarpanels or heat recoveryfrom refrigeratorG Heat source from boiler1412Technical SpecificationsNote: The above performances are based on a primary flow temperature of 85°C and a domestic cold water inlet of10°C, without the use of a thermostatic mixing valve on the domestic hot water outlet. If the boiler is heated usingthe immersion heater, domestic hot water output depends on the heating element fitted.Maximum Operating PressurePrimary: 3 barSecondary: 10 barCoil: 13 barFactory Test PressurePrimary: 4.5 barSecondary: 13 barCoil: 20 barMaximum Operating Temperature90°CHR FB HR FB ACCU B ACCU B300 450 600 800Code 06254201 06603202 06240201 06240401TankTotal capacity L 360 450 618 809Primary capacity L 189 261 434 625Heating surface area m2 1.99 2.58 2.16 2.16Primary pressure drop mbar 90 75 60 60Primary flow rate L/h 5400 5700 n/a n/aMaximum usable input from boiler kW 63 63 38 38Primary connections (female BSP) Ø 1” 2” 11/4” 11/4”DHW connections (male BSP) Ø 1” 11/2” 1” 1”Immersion heater connection Ø 11/2” 11/2” 11/2” 11/2”Dimensions height mm 1900 1860 1730 2030width mm 680 750 1020 1020depth mm 680 750 1020 1020Weight empty Kg 190 212 251 280Weight full Kg 550 662 869 1089CoilSurface area m2 2.6 2.6 2.6 2.6Primary connection (male BSP) Ø 3/4” 3/4” 3/4” 3/4”Flange diameter mm 190 190 190 190Length mm 610 610 610 610Pressure drop mbar 160 160 160 160Primary flow rate L/h 700 700 700 700Rated output kW 13.12 13.12 13.12 13.12HR FB HR FB ACCU B ACCU B300 450 600 800Peak flow 40°C L/10’ 427 455 280 303Peak flow 45°C L/10’ 366 390 240 260Peak flow 60°C L/10’ 220 270 144 182Peak flow 1st hour 40°C L/60’ 1930 2474 1094 1211Peak flow 1st hour 45°C L/60’ 1654 2120 938 1034Peak flow 1st hour 60°C L/60’ 562 726Continuous flow 40°C L/h 1804 1940 1089 1089Continuous flow 45°C L/h 1546 1662 933 933Continuous flow 60°C L/h 653 653Domestic Hot Water PerformancesHR FB/ACCU
