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. Including a clamping strip with which a temperature sensor can be affixed at any chosen height to enable optimum heat efficiency of the water heater. Feet adjustable in height for accurate levelling. Inspection flange at the side: DN 205, suitable for connecting additional heating elements; Ex Works - closed with a removeable blind flange. Suitable for connecting additional heating elements and fitted with a coupling sleeve for accessories. The heating coil is designed to ensure full depth heating to prevent the accretion of Legionella bacteria.
