Our new soaking bathtub heater is designed to maintain the bathtubs water temperature between 102 F and 104 F and eliminates the bather having to constantly add hot water. The heat system is comprised of a patented suction inlet and outlet fitting, on/off control, super quiet pump, 1500 KW heater, 20 minute safety timer and rigid PVC pipe that insures the heat system drains 100% when the tub is emptied. Building codes require that an access area be constructed to service the heater. The heater comes with a standard chord and plugs into a 20amp GFIC protected circuit, U.L. recognized. Devices that claim to produce heat keeping the bathwater hot by friction have no scientific testing to verify that false claim. Click here for more Info.
