Why does the furnace water cool when it's not calling for heat?
When the furnace is not calling for heat, the burner is not running and heat is not being generated. As a result, the water in the furnace cools down naturally over time as it loses heat to the surrounding environment. This is a normal process and ensures that the water temperature is maintained at a safe level when the furnace is not in operation.
How is your endocrine system like the thermostat in your house?
The negative feedback system. It works much the way a thermostat works. When the temperature in a room drops below a set level, the thermostat signals the furnace to turn on. Once the furnace has raised the temp in the room to the set level, the thermostat signals the furnace to shut off. It will continue to stay off until the thermostat signals that the temp has dropped again.
Why does a home ac blow heat until it gets about 2 degress below what it's set for and it start's blowing cool air?
That is the function of the fan/limit control on your furnace. When the thermostat nears the point where the room temp setpoint is satified it shuts off the flame. The fan/limit control keeps the fan on for a minute or so to cool the furnace down before shutting off. Conversly, if your watch your furnace at start up you will see the flame lights first but the fan does not come on for a minute or so to allow the furnace to get hot and avoid blowing cold air into the home.

How many watts does an electrical furnace draw?
An electric home furnace is in the neighbourhood of 10 kW to 50 kW depending on the square foot area of the home. A 10 kW furnace would require a 50 amp sub feed from the main distribution panel, a 50 kW unit would require a complete 200 amp service.In colder climates the cost of operating this type of furnace would be higher. The furnace's heating elements come on in stages depending on how cold the home is on start up. As the home reaches the thermostat set point the home will be maintained by just a couple of the elements.Electric heating of the home is a very expensive way to heat, by blowing air over an element that looks like your oven element.
What is the most efficient way to set a home thermostat?
For basic settings, and best results, set your temp. for cooling at about 75 degrees F. or at the highest possible temp. that you can and still be comfortable. The same is true for the temp. setting for heating mode except in reverse. For heating, about 68 to 70 degrees is normal or the lowest temp. possible. This will allow your A/C to run less and operate more efficiently.

It is best to have a professional HVAC technician inspect and diagnose the problem to ensure safe and efficient operation.
