Abstract
A hydro excavation heating system includes an internal combustion engine having an exhaust gas stream, a heat exchanger coupled to the exhaust gas stream and configured to heat hydro excavation water by transferring heat from the exhaust gas stream to the hydro excavation water circulating therethrough, and a tank for storing the hydro excavation water. The system also includes a water pump having an inlet coupled to an outlet of the tank storing the hydro excavation water, a hydro excavation hose coupled to an outlet of the water pump, and a coupling coupled to the hydro excavation hose and to an inlet of the heat exchanger to define a closed circulation path through the system when heating the hydro excavation water, where the coupling is configured to disconnect from the heat exchanger in order to use the hydro excavation water during a hydro excavation operation.
