4reboy is right, detach the 4 nuts around the heater motor, detach the heater motor wires, detach the hoses from the engine, remove the screw above the fresh air door, the heater falls down, detach the 3 Bowden cables and defogger hoses, and remove the heater from the car. In your case, since you are only after the hoses, leave the Bowden cables and defroster attached, remove the water hoses, install the new hose from the engine side, reinstall the heater, trim and attach the hoses to the engine, as shown below. The whole job should take under an hour.
