Technical Specifications
Note: The above performances are based on a primary flow temperature of 85°C and a domestic cold water inlet of
10°C, without the use of a thermostatic mixing valve on the domestic hot water outlet. If the boiler is heated using
the immersion heater, domestic hot water output depends on the heating element fitted.
