The present invention relates to a heater (1) with electrical resistor-type conductors (23) for water beds (3,4,5), which is arranged between a bed frame (3) and a safety liner (4), and which can be regulated as a function of the desired temperature of a water-filled bladder (5) that lies upon the safety liner. It is the task of the present invention to create a heater of the type described for water beds, which is distinguished by greatly improved thermal transfer and greater safety, and which, at the same time, prevents hot spots, heat buildup, and changes to the softener. According to the present invention, this problem has been solved in that it is provided with ceramic plates (13-18) that incorporate integrated electrical conductors (23) that are baked in place; these ceramic plates are attached by an adhesive (19) that is thermally conductive to the underside (11a) of a rigid metal plate (11) that is locked onto a base plate (12) that is of low thermal conductivity, whilst leaving an air gap (33) for the ceramic plates (13-18), and which is installed on the bed frame (3).
