In a normal house furnace a fan forces air through an exchanger. This usually consists of some pipes or tubes. A fire on the outside of the tubes heats the air inside the tubes as it passes. The force of the fan also pushes the air along duct work and the warmed air comes out floor vents or regesters. The suction of the fan draws air from through out the house through the larger wall mounted cold air vents. The air passes through a filter and then into the fan where it is then sent to the exchanger. The thermostat that you set for the desired temperature measures the room temperature. When the temperature falls below the set point the thermostat sends a signal to the furnace to start the fan and then turn on the flame. When the temperature at the thermostat rises above set point the signal to the furnace is shut down, the fire goes out and the fan stops.

What is the Heat loss in blast furnace?
In a furnace large amount of the heat supplied is wasted in the form of exhaust or flue gases.. that s called as heat loss in a furnace..
Why does furnace heat only part of the house?
You need a furnace expert to come and inspect it and tell you the answer.
Does a furnace use radiation conduction or convection how do you know?
All three.A furnace burns something, this creates heat which can dissipate in those 3 ways.All 3 occur:Radiation: the fire radiates heat which can be seen with infrared goggles.Convection: The fire heats up air which rizes and leaves the system.Conduction: The fire heats up the materials of the furnace, causing the heat energy to heat up the air on the outside of the furnace, which in turn convect.
Where does the heat from a furnace keeping your house warm go?
The heat pretty much stays in your house. The heat from the furnace rises (because the molecules have moved apart) and goes to the top of the house. There it cools down, and because it is not more dense, it sinks back down to the furnace where it can be made warm again. All this happens through a process of heat transfer call convection.
How can you generate heat energy?
take a dump! :)
How is oil used to form electricity?
Oil is burned in a furnace as fuel to produce heat. Running through the furnace is a series of pipes containing water. The water turns to steam with the heat - which is then used to turn turbines. The turbines generate the electricity.
Divice for regulating furnace heat?
There is always a wall thermostat for regulating furnace heat.

Why does Furnace shut off when very cold outside?
A heat pump will do this, a furnace should not. Are you sure you have a furnace?

Will replacing the heat exchanger prolong the life of your furnace?
The heat exchanger in a furnace is the primary component in a furnace. That said, their are circuit boards, motors and other components that can also fail regardless of the age of the heat exchanger. In my opinion, if you can afford to replace the furnace, you would be much better off. The cost of the heat exchanger with labor is probably not too much less than replacing the entire furnace.
What is the difference between a gas Furnace and a heating furnace?
While both furnaces and boilers fall into the category of heaters, they do have a number of noticeable differences in the way they operate. The main distinction has to with the way they distribute heat throughout your house. A furnace relies on natural gas combustion or electric resistance to generate heat. This heat is then transferred to the air via a heat exchanger and distributed via ductwork throughout your home. Furnaces are forced-air heating systems that are highly efficient and can produce a lot of heat relatively quickly. However, a system that uses ductwork to distribute heat may develop leaks, letting some heat escape and losing some of its efficiency.
