The bundle is intended for heating water and can be used in appropriately planned open or closed central heating systems.\u003c\/p\u003e \u003cp\u003eThe MDC module handles the hydraulic integration into the heating circuit, while the TEHP25 immersion heater provides the electric heat output. This makes the bundle suitable for applications where additional electric heat input into the heating circuit is required.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe MDC 230 module is designed as an electric heating module or flow heater for central heating systems. It features a steel tank, 50 mm polyurethane foam insulation, a heating circuit connection with 1 1\/4\u0026quot; female thread, and a heating cartridge connection with 1 1\/2\u0026quot; female thread.\u003c\/p\u003e \u003cp\u003eThe TEHP25 immersion heater is a screw-in heating element with 2.5 kW output at 230 V. It features a 1 1\/2\u0026quot; connection thread, a temperature controller, a safety temperature limiter, an integrated indicator light, IP54 protection rating, and a sheath material of Incoloy 825.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe bundle provides a compact way to integrate supplementary electric heat directly into the heating circuit. This can be particularly interesting for operators when an existing heating system is to be supplemented with an additional electric heat source.\u003c\/p\u003e \u003cp\u003eThe separate combination of module and immersion heater facilitates the professional assignment of components: the module is hydraulically integrated, while the immersion heater handles electric heat generation. This keeps the system layout, technical data, and subsequent maintenance clearly traceable.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eSystem Integration \u0026amp; Compatibility\u003c\/h2\u003e \u003cp\u003eThe MDC 230 module is integrated into the parallel heating circuit on the flow or return line of the main heat source. The medium is water or a suitable glycol mixture up to a maximum concentration of 50%.\u003c\/p\u003e \u003cp\u003eFor operation, proper hydraulic integration, an adequate minimum flow rate, an additional circulation pump, and a safety valve with an opening pressure of 1.0 MPa must be considered.
