The heat pump runs the compressor motor at a lower RPM, which reduces the power needed for a given amount of heat pumped. Most heat pumps also reduce the blower fan speed proportionally, but the power savings come almost entirely from reducing the compressor speed.

OK, but is that while achieving the same flow teperature or a lower one?
