I decided to measure the temperature of the heater in the car and truck. It has been in the teens to 30s F around Louisville so I am definitely using the heater more. The Ford Ranger truck always seemed to have a hot heater. I used a meat thermometer to measure vent temperature. The vent temperature came out to be 160 degrees F when the air flow was selected for front vents, lowest air flow rate and full heat.
The Nissan NX-1600 puts out 110 degree F air when the vent is selected for lowest air flow rate, front vents, and full heat. If the flow selector is set to front and floor vents the temperature on the front vent is 80 degrees F. If the defrost vent is selected, the front vent goes to 60 degrees F. The vent is also set to allow fresh air in so that makes the air cooler. The outside air was in the 30s when the measurements were made.
