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.
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..
You need a furnace expert to come and inspect it and tell you the answer.
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.
i set my thermostat to cool, my heat pump start it go to heat but not cool, i think the thermostat. can u help.
There is always a wall thermostat for regulating furnace heat.
A furnace by definition provides heat. There must be something that controls that heat; that is that tells the furnace when to fire up the burners and when to shut down the burners. This function is provided by the furnace control system. Usually the control system itself is controlled by a thermostat which maintains the temperature at a preset level on the thermostat.

when running the heat-pump the air blowing from the heat ducts is not hot ( it's to cold for the heat-pump). you have a main furnace and it won't turn on ( is thermostat selected for this source), ( is the power switch for main furnace on ), ( is fuse for this furnace good). If these are good (check thermostat wiring at thermostat, and transformer).
Thermostat
A device for regulating furnace heat is the thermostat. A programmable thermostat can be set to control the temperature inside the home on a regular schedule. The thermostat is set to a desired temperature and then the furnace turns on and off to accomplish the desired heat level.
thermostat is commonly used to regulate the heat of a furnace. It can programmed to maintain a desired temperature by turning the furnace on or off as needed. Some thermostats have additional features such WiFi connectivity, smart home integration, and scheduling options.
In the instruction manual for the furnace, it will either give you the heat anticipator setting or instruct you how to do it. If its digital, well then follow the thermostat instructions
The power to the thermostat comes from the transformer in the furnace or air handler whichever you have. 1) the power to the furnace/AH is off, 2) the control fuse that protects the transformer is blown, 3) the transformer is defective, 4) the wire between the furnace and the thermostat got cut.
A programmable thermostat works fine with a heat pump. Just remember that a heat pump does not heat as fast as a furnace because of the lower BTU ratings so do not set the thermostat as far back as you normally would. Also make sure to buy a thermostat that has heat pump terminals.
If the furnace is a single stage heat model. Use R,W and G at the stat and the furnace. This info is in the Installation Manual. R is 24 volt hot,W is heat and G is fan.
