An internal combustion engine powers a prime mover for a bitumen slurry well head pump used at a CHOPS site to pump bitumen slurry from a well borehole. A storage tank stores the bitumen slurry at a location adjacent to a CHOPS site. Hot exhaust from the engine flows along an exhaust conduit and into an exhaust-to-glycol heat exchanger. The glycol is pumped in a recirculating circuit from the exhaust-to-glycol heat exchanger into and through a glycol-to-bitumen slurry heat exchanger to thereby heat the bitumen slurry in the storage tank. Cooled glycol is recirculated back through the exhaust-to-glycol heat exchanger. Engine coolant is inter-mingled with the glycol flowing into the glycol-to- bitumen slurry heat exchanger. Glycol returning from the glycol-to-bitumen slurry heat exchanger also returns to the engine coolant circuit. A controller regulates exhaust-to-glycol heat exchanger and engine temperature.
