Heating and cooling for the Octavia iV

How is the heating and cooling achieved? I assume it's electric as the car can be pre-conditioned when parked. Is there any heat obtained from the IC engine when it's operating? On a journey with the various temperatures displayed using hybrid power, the oil temperature and water temperatures were quite low - the oil never exceeded 60 degrees Celsius. I haven't checked the temperatures on a longer run when the IC engine does all the work.
