It uses external air as a heat source to provide heating and hot water. Since the indoor unit contains the water tank, hot water and heating can be provided without additional water tank installation.

THERMA V R410A IWT(Integrated Water Tank) type operates according to the three operation modes you set. To reduce the heating cost, user can set operation at Economical mode. To make the room temperature warmer, Comfort mode can be the ideal option. User can set the desired operation mode at desired time zone by scheduling function.

The target temperature of leaving water is automatically determined based on the outdoor air temperature in Weather Dependent Operation. If outdoor temperature decreases, heating capacity for the house will automatically increase in order to maintain the same room temperature.

LG’s unique Smart Sensor with pressure and temperature controlling technology senses pressure directly for faster and more exact response to load variation.

Even in case of sudden product error, THERMA V continues ongoing heat production until proper service takes place. In case of minor error which is mainly caused by sensor malfunctioning, heat pump cycle is forced to operate. For major errors caused by defects in cycle parts, electric heater runs to maintain heating operation.
