ACV 10800275 kit elemento calefactor BL 30kW LCA DN110

This is a kit for a heating element, part of the ACV range under catalogue article 10800275. Heating elements of this type are immersion-style electric resistors that sit directly in the water flow of a boiler or thermal store. They convert electrical energy into heat when the burner is not running or to supplement the burner output during high demand. The element is controlled by the boiler’s control board via a contactor or solid-state relay, and its operation is usually governed by a dedicated temperature sensor or the main NTC sensor. When selecting a replacement heating element of this class, the key parameters are the rated power (in kW), the voltage supply (typically single-phase or three-phase), the immersion length, and the flange or thread size that seals into the boiler body. The element may include an integral thermostat or thermal cut-out for overheat protection. For this specific kit – ACV 10800275 – the power is stated as 30 kW and the flange size is DN110. The kit likely contains the heating element assembly, gasket, and possibly a temperature sensor or wiring harness. During a replacement, always verify the electrical supply and the control logic: some boilers use a modulating firing rate for electrical elements, while others simply cycle them on/off. Poor electrical contact at the terminals can cause nuisance tripping or intermittent heating; ensure all connections are clean and torqued to specification. The DN110 flange seal must be replaced with the supplied gasket to avoid water leaks. After fitting, check the insulation resistance before powering up, and confirm that the safety cut-out operates correctly.
