A temperature controlled fluid therapy system includes a reservoir for containing hot or cold fluid, a pump with a submersible motor disposed within the reservoir, a watertight blanket for containing the hot or cold fluid, and output and intake conduits for circulating the fluid between the reservoir and the blanket. The system includes a first temperature sensor disposed within the reservoir for measuring the temperature of the fluid in the reservoir, and a second temperature sensor disposed adjacent the blanket for measuring the temperature of the fluid in the blanket. A power supply provides power to the pump motor.
