Sounds like your heater has dust bunnies and needs a good cleaning, when dust or fluff heats up it starts to singe or burn causing the burning smell.
The distinct burning hair smell is caused by the burning of keratin proteins in hair when exposed to high heat. To prevent this smell, avoid using excessive heat on hair, use heat protectant products, and ensure proper ventilation when using heat styling tools.
Because fire is just heat of what’s burning. Like fire on its own is noting. It’s not possible. Fire is just heat, but if you put that heat on wood it’ll smell like burning wood. same with meat and other stuff. Heat doesn’t have a smell.
Friction from excessive braking causes heat, thus the lubricant on brakes release this burnt smell.
A car may smell like something burning after sitting at a light with the heat on due to several reasons. One possibility is that the heater core, which circulates hot coolant, could be leaking, causing coolant to burn on the engine or exhaust components. Another reason might be debris, such as leaves or trash, that has accumulated around the engine and is overheating. Additionally, worn brake components can generate a burning smell if they are engaged for an extended period while idling.
i would get some one to check that out it sounds pretty scarry! i would stay out of that room for a while.
Your heater may smell due to dust or debris burning off when it is first turned on after a period of inactivity. This is normal and should dissipate after a short while. If the smell persists or is accompanied by other issues, it may indicate a more serious problem that requires professional attention.
It could be your heater fan bearing. But more than likely its something in your engine compartment that is making the smell. Such as oil burning on the exhaust or a worn accessory belt.

If your going through coolant then you have an internal head gasket leak you smell coolant because its getting into cylinder and burning
Sometimes when parts are new, they have coatings and etc. that will smell when parts are warm. For example, alternator windings are coated with a electrical varnish. When the alternator is charging, it creates heat. This causes the paint to smell and odors such as a burning smell can be common for a couple of days.
during a brand new cars "break in" its normal to smell like somethings burning, coming from the brakes and exhaust...the metal on the disc brakes and the pads heat up for the first time making it smell like somethings burning, same goes for the catalytic converter in the exhaust system.
Burning a disc can produce a faint smell due to the heat generated during the process. However, if you notice a strong or unusual odor, it may indicate a problem with the disc or the burner and you should stop the process and investigate further.
