Two Heat Pumps in Two Model 3 Vehicles
We have another video, this time comparing heat pumps from Out of Spec Reviews with two Model 3 vehicles in the extreme cold being heated up as fast as possible. There is a PTC resistive heater in a 2019 Model 3 and a 2021 Model 3 with a heat pump. He thinks the 2021 will be faster.
In the frigid temperatures, the PTC heat pump might actually have an advantage, in the older Model 3. He had a thermometer in one Model 3 that showed -20 degrees Farenheit and the other Model 3 had the sampe temperature. It was really cold!
He turned on the heat in one of the Model 3's, the 2021 version, and nothing responded right away. After a few seconds, the fans turned on and the heat pump began to start. It was -20 degrees and the Model 3 was on full high. It was over a minute with no change in temperature.
The car was still very frozen with ice all over the outside of it. 3 minutes later, the heat was continuing to go, but the air wasn't warm yet - but it was getting there. 4 minutes later, the heat was continuing to blow. After 9 minutes, the heated seat started to come through and the air started to get warm. The temperature started to get a little warmer.

The Heat Pump Competition
The PTC Model 3, the 2019 version, was also heating up and it was getting close to 0 degrees. He was running heat in both Model 3 vehicles at the same time. It was 12 minutes now and the 2021 Model 3 wasn't blowing any real hot air yet. Both thermometers crossed the 0 degrees Fahrenheit mark now.
16 minutes in and the 2021 Model 3 was over 20 degrees Fahrenheit. The 2019 Model 3 hadn't made it to 20 degrees yet, but was close. The 2021 Model 3 was starting to feel warm and that there was actual heat. This was at almost 20 minutes of preheating the vehicle.
At the 21 minute mark the 2021 Model 3 was close to 40 degrees Fahrenheit, but the 2019 Model 3 was still at about 20 degrees. The newer Model 3 was pulling away. There was some meaningful heat coming in the newer Model 3 and the ice on the car was melting away. The steering wheel was also getting warm too.
At 28 minutes, the newer Model 3 is almost 60 degrees Fahrenheit and the older Model 3 was at about 35 degrees Fahrenheit. At the 29 minute mark, the 2021 Model 3 was now at a comfortable temperature. At 32 minutes, the 2021 Model 3 was over 60 degrees Fahrenheit and good to go.
His wife was in the 2019 Model 3 and it was definitely slower to heat up. Even at 33 minutes, the car wasn't heated up yet. The car just hit 40 degrees at the 33 minute mark.
My conclusion is that newer Tesla Model 3 vehicles heat up faster in the extreme cold. This is good to know. What do you think of this experiment between and older and newer Tesla Model 3? Would you get one?
