Two independent smooth-tube heat exchangers allow the hydraulically separate integration of two heat sources, for example a solar thermal system and a boiler, a wood heating system, a heat pump, or another suitable heat generator.\u003c\/p\u003e \u003cp\u003eThis version is suitable for bivalent hot water systems with increased storage volume. The storage volume declared for energy labeling is 392 liters.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eTechnology \u0026amp; Equipment\u003c\/h2\u003e \u003cp\u003eThe drinking water tank is made of steel S235JR and is enameled on the inside. Two magnesium anodes supplement the corrosion protection. The two hydraulically separate smooth-tube heat exchangers are made of steel P235GH in this version.\u003c\/p\u003e \u003cp\u003eThe lower heat exchanger has a transfer surface of 1.6 m² and achieves a continuous output of 50 kW under defined test conditions. The upper heat exchanger has 1.0 m² of transfer surface and a continuous output of 34 kW. The actually achievable heat transfer depends on temperatures, volume flows, and the hydraulic design of the connected system.\u003c\/p\u003e \u003cp\u003eThe equipment includes an inspection opening, a circulation connection, several thermometer pockets for temperature sensors, a thermometer connection, and connections for an optional electric heating element. The permanently integrated 50 mm PUR rigid foam insulation reduces heat loss to the installation room. The tank achieves energy efficiency class B with a standby heat loss of 63 W.\u003c\/p\u003e \u003c\/div\u003e \u003cdiv class=\"gema-section\"\u003e \u003ch2\u003eEveryday Benefits\u003c\/h2\u003e \u003cp\u003eThe two separate heat exchangers create a flexible basis for systems with regenerative and conventional heat generation.
