Portable apparatus for supplying hot water to a diver's suit and which has a portable water pump that can be located closely adjacent a water source so as to minimize the lift required by the pump, a compressed air source that normally furnishes compressed air to the breathing apparatus of the diver and which is also used to drive the water pump by means of an air motor, a portable water heater having a source of fuel for heating the water is connected to the discharge side of the water pump for receiving cold water and heating it, the hot water is discharged from the heater and is mixed with cold water to the desired temperature and then furnished to the diver's suit. All of the components of the apparatus are portable and the entire system is flexible as to its location and set-up, there being no fixed apparatus or installations required. The water pump is operated by the air compressor which furnishes compressed air to the breathing apparatus of the diver and the pump can be remotely located from the heater and is located adjacent the water source so that the net positive suction head required by the pump is satisfied. The pump is also pressure compensated so that the pressure can be set and the pump will supply the amount of water at a particular pressure on demand, and the air consumption of this positive displacement pump is limited to a reasonable amount and does not unduly burden the diving system. With the present apparatus a minimum number of components are required and the entire arrangement is highly portable and easily assembled and disassembled.
