If the current flowing through an electric heater increases from 6 to 12 amp while the voltage remains the same the heat produced by the heater will be what?

Since power is current times voltage, doubling current while keeping voltage the same will double the power. Ignoring slight non-linearity, if the power doubles, the heat will double.


Does the heater work when the coolant level goes below minimum level?

The heater is dependent on the coolant flowing through the heater core. If the coolant is low then there will not be any heat.

Divide 25,000 by the supply voltage to get the current.


Will the thermostat in 1996 grand am keep the heater from warming the inside of the vehicle if it is defective?

YES...IF IT HAS STOPPED WORKING IN THE CLOSED POSITION THEN THE HEATED WATER ISN'T FLOWING THROUGH THE HEATER CORE.


Why is there no heating in your Jeep Cherokee Sport?

1. Is coolant flowing through the heater hoses and heater core? Once the care is fully warmed up, running, and the heater on, the hoses going to and from the heater core should be hot to the touch. If not, coolant may not be flowing. 2. Is the heater door, under where people's feet are, broken? This URL may help explain http://www.heatertreater.net/jeep Cherokee 97-04.html

Could have a clogged line feeding the heater core. Disconnect return hoses from the heater core and verify coolant is flowing through the core.


How do you install a heater core on a 1968 Chevy impala?

Bolt the heater core into place, with the four retaining bolts. Connect the water supply hoses. You might need to bleed one of the hoses to get the water flowing through the heater core.


How does the heater control valve for f150 operate?

There really isn't a heater control valve. The coolant flows through the heater core at max pressure and temperature is controlled by controlling the amount of air flowing through the heater core. This is the function of the blend door and this is a fairly common failure on Ford trucks. Check heatertreater.net for diagnostic information and suggestions on how to repair the system.


Does the resistance of heater coil remains same when current flows through it?

Typically resistance rises with temperature.

Why does the cord of an electric heater not glow while the heating element does?

The heating element of an electric heater is a "resistor", the cord which conducts the electricity is not. The resistance of the element of an electric heater is very high. As current flows through the heating element, it becomes red hot and glows. On the other hand, the resistance of the cord is low. It does not become red hot when current flows through it.
