The internal heat exchanger unit utilizes the energy from a solar thermal system or the heat from a boiler, thus ensuring a consistently high level of hot water comfort.\u003c\/p\u003e  \u003cp\u003eBy combining it with your photovoltaic system and an optional heating element, the energy yield can be further increased. This allows you to benefit from independent, environmentally friendly hot water preparation even on days with little sunshine.\u003c\/p\u003e  \u003ch3\u003eCorrosion protection and durability\u003c\/h3\u003e  \u003cp\u003eFor long-term, trouble-free operation, the interior of the storage tank is lined with high-quality enamel. Additionally, a generously sized magnesium sacrificial anode protects the metal from corrosion and significantly extends its service life.\u003c\/p\u003e  \u003cp\u003eThe rigid polyurethane foam (PUR) insulation minimizes heat loss and keeps your energy costs low. Even at maximum storage loads up to 95 °C, the material performs reliably and remains dimensionally stable.\u003c\/p\u003e  \u003ch3\u003eFlexibility and connectivity options\u003c\/h3\u003e  \u003cp\u003eThe hot water storage tank has all standard connections: heating and return, domestic hot water supply and return, and circulation in ¾\u0026quot; male thread. An additional connection for a 1 ½\u0026quot; electric heating element can be retrofitted to integrate other heat sources.\u003c\/p\u003e  \u003cp\u003eThis system is compatible with solid, wood, pellet and combination boilers, as well as solar thermal systems. This makes it versatile and allows it to be flexibly adapted to existing heating concepts.\u003c\/p\u003e  \u003ch3\u003eTechnical data and model variants\u003c\/h3\u003e  \u003cp\u003eStorage capacities range from 100 to 180 liters and reliably cover the hot water needs of small to medium-sized households. The heat exchanger surface area varies between 1.2 and 1.67 m² depending on the model, and the exchanger volume between 5.3 and 7.8 liters.\u003c\/p\u003e  \u003cp\u003eMaximum operating pressures are 6 bar for the storage tank and heat exchanger, with a maximum temperature of 95 °C in the storage tank and 100 °C in the heat exchanger. Heat losses range from 28 to 42 watts, depending on the volume.\u003c\/p\u003e  \u003cp\u003eDimensions and weights:\u003c\/p\u003e  \u003cp\u003e– 100 liters: Ø 625 × 770 mm, empty 64 kg\u003cbr\u003e– 120 liters: Ø 565 × 1045 mm, empty 71 kg\u003cbr\u003e– 150 liters: Ø 625 × 980 mm, empty 76 kg\u003cbr\u003e– 180 liters: Ø 715 × 1030 mm, empty 88 kg\u003cbr\u003e\u003c\/p\u003e  \u003ch3\u003eRetrofit electric heating element\u003c\/h3\u003e  \u003cp\u003eFor additional heating requirements, a 1.5 kW, 2.0 kW, or 3.0 kW heating element can be installed. All versions feature a temperature controller (23–75 °C), a safety limiter (85 °C), and operate with IP44 protection.\u003c\/p\u003e  \u003cp\u003eThe electrically insulated design with a plastic housing and temperature-stabilized alloy (Alloy 825) guarantees high corrosion protection. The heating elements operate on a single phase (230 V\/16 A) and provide flexible support as needed.\u003c\/p\u003e  \u003ch3\u003eTechnical specifications 100 liter storage\u003c\/h3\u003e
