It could be one of many reasons... water pump, thermostat, cooling system to name a few. I had no heat in my car during a very cold spell and had the mechanics do a reverse system flush. (Whatever the heck that is.) But it seemed to work on my car.
by fire . an electric heater is a metal, and a metal is a good conductor of heat. so it can produce heat
The part that generates heat... depending if it is a gas / electric heater
a heater. the sun. you. burner. fire...
Yes
A light bulb similar to a heater in that they both produce heat when in operation.
I would guess the thermostat I would guess the thermostat
No , if you were to bypass the heater core , you would have no heat
There are two insulated heater elements that heat the water.
I don't think so because when we have a cold, it is best to keep oneself warm and thus the heater produce heat for us to keep warm. Unless we have a lousy heater which produce cold air instead of heat, haha!
enough.
it is a heater. heat. it blows heat. warm air
The heater contains a resistor. When high voltage is passed it produce a large amount of heat the blower situated in the heater blows this heat which diffuses in the room to make the room hot.
