Eli5: If I get in a cold car and want the temperature inside to be 71, so I set it for 71 or set it higher until I am uncomfortable?

Question

What is the fastest way to heat the inside of a car or room. Set the heater to desired temperature or initially set it higher than wanted?

Answer 1

Just set it to where you want it.

99% of temperature systems don’t slow down as they get close to cut off.

They heat FULL POWER HEAT UP RIGHT NOW! Until the thermostat says “yeah we’re warm enough now”

If you set it higher than you want it, you waste energy overshooting where you need to be. Plus you end up too hot then.
