ABSTRACT:
Tubs are supplied with hot water through a water circulation system including a pump, an elongate electric flow-through heater, a water filter and piping connecting that pump, elongate flow-through heater and water filter in series in that water circulation system. The pump, elongate flow-through heater and piping are arranged in a horizontal plane so that water flow passages in that piping, in the elongate flow-through heater and in the pump are intersected by that horizontal plane extending along directions of water flow in the mentioned water flow passages. The pump may be provided with a water inlet and a water outlet both lying in the same horizontal plane as the elongate flow-through heater and piping. The pump also may be provided with an axis of rotation, and even with an electric drive motor, extending in that horizontal plane. The elongate flow-through heater may be provided with an elongate structure molded of an electrically insulating synthetic resin for housing an electric heating element. A metal plate is sealed to that elongate housing structure at a lateral opening thereof in parallel to the above mentioned horizontal plane, as both a base for the electric heating element and as an electrically conductive complement of the electrically insulating housing structure.
