The new heater is available in four different performance classes, which are indicated by the number in the product name: thermopreset50 (50W), thermopreset100 (100W), thermopreset150 (150W) and thermopreset200 (200W).  Common to all variants is the slim design – with a diameter of only 2,8 cm and a length of 17 to 25 cm, the heater is hardly visible also in small basins.
