* Dimensions including insulation.
** At 80 °C supply temperature and 60 °C potable water temperature.
An indirectly heated and upright water heater including a permanently welded-in heating coil, suitable for all modern heating systems.
Minimum lime deposits due to smooth surfaces. High-quality glass lining according to DIN 4753/part 3 for potable hot water production and optimum corrosion protection by means of a standard Mg-anode. Equipped with a built-in thermometer and immersion pipe. A set of adjustable feet is optionally available (Art.No. 18989). From 400 litres, equipped with a DN 110 inspection flange at the side, suitable for connecting additional heating elements; Ex Works - closed with a removeable blind flange. The heating coil is designed to ensure full depth heating to prevent the accretion of Legionella bacteria.
