ELECTRICAL INSTANTANEOUS WATER HEATER

摘要

The invention relates to an electrical instantaneous heater for heating water, comprising a housing and a heating block, through which water can flow and which is arranged in the housing and and has a water inlet and a water outlet which are in fluid connection with a cold water supply and a hot water discharge of the housing, characterized in that the housing has an upper and a lower bore pair in a vertical installation position, wherein the bores of each bore pair can be assigned to the cold water supply and the hot water supply, wherein an internal piping system is present for the fluidic interconnection of the cold water supply positioned in the respective bore to the water inlet and of the water outlet to the hot water discharge positioned in the respective bore. The present invention is particularly suitable for the flexible use of an instantaneous heater as an under-surface design or as an over-surface design.
