How big a house will a 75000 btu furnace heat?
Heat load calculations need to be conducted for home to determine the proper size furnace. There is no simple answer to this question. There are a number of factors that can effect what size your furnace should be. Example: square footage, duct work size, insulation factors, windows etc. I recommend having a heating professional look at your home and conduct a heat load calculation. Over sized and under sized furnaces can cause you number out problems in the long run.

You need to insure it at replacement cost not value or appraised value. Call your agent.
There are different types of heating coils. Most are electric heat strips, refrigerant coils or hot water(hydronic). Your furnace\heater fan blows across the coils to heat your home or office.
The most comon way to detect a crack in a heat exchanger is with a visual inspection, removal of the burner assembly and the use of a mirror and flash light.. Or a smoke bomb test. A special little smoke bomb is placed in the burner area with the burners OFF. The blower is runnig and you light the …smoke bomb, the smoke will draft up the flue vent or if a crack or rust hole is present then the smoke will get sucked into the air stream and come out of the duct work.. Other than that using a carbon monoxide detector to see what the CO levels of the furnace are and comparing them to the supply air of the furnace to verify that there is no CO present in the air stream.. The best and most accurate way is to contact a local Heating and Air Conditioning specialist or your local gas company should come out and perform a CO test on the furnace..

\nWhat ever it take to keep you warm - and add moisture to keep it toasty.
Yes, a 14,000 BTU furnace will heat your 500 square foot room justfine. Make sure you test it out to make sure you don't turn it uptoo high at first.
On average it takes about 1,600 BTUs to heat 50 square feet.Multiplying 50 by 1600 equals about 80,000. Therefore, the heatingplan of 1,600 square foot are would take about 80,000 BTUs.
Mainly convection I should think, if it transfers heat to a water or air heating system. There will be some radiation and conduction to the area immediately surrounding it.
A general rule of thumb in estimating the size of furnace needed toheat a home is to find the square footage of the home, and multiplythat by 45 BTU (British Thermal Unit). For a 3200 square foot homea furnace somewhere in the range of 144,000 BTU would be areasonable estimation of the furnace size …needed to heat the home.To find the most efficient furnace for any given home, however, itwould be best to contact an HVAC professional who can perform aload-calculation.

Mechanical penetrations (Supply or Return Air Vents) are not allowed in garages in residential construction under the International Residential Code.. . Some countries' Building Codes and/or Regulations may allow a garage to be heated by a normal water-heated radiator supplied by the house's furna…ce or hot water calorifier. (Calorifier = "boiler" in everyday language.) . To find out if it is allowed where your home is situated you must check the Building Codes and/or Regulations for your locality i.e. Town/State/Country or - better still, as you needed to ask this question here - ask a locally-licensed plumber or HVAC (Heating Ventilation and Air Conditioning) technician for advice. . . Yes you can, as long as you use a 1 way trap tha restricts the airflow only to the garage and not backwards. "International building codes" do not apply everywhere (MORE)
This is how a furnace heats your home.. When the thermostat calls for heat, a signal is sent to the gas valve. If you have an older unit, the gas valve checks to see that the thermocouple sees the pilot and if it does, the gas valve opens to send gas to the burners.. If you have a newer furnace, t…he thermostat sends a signal to start the pilit ignition sequence (either spark or hot plate) and then the flame rod sees the pilot (of the hot plate is up to temp.) the gas valve opens to send gas to the burner.. The fan control will then send a signal to the blower to start up. As the temp rises in the room, the thermostat sends a signal back to the gas valve to close as it reaches the set point on the thermostat and the blower continues to run until the set point on the fan control is reached and it shuts off ending the cycle..

Goodman hot air gas furnace and you get more heat out of your vent then you do your registers in your house what could cause this problem?
Closed dampers or registers, not sure what you mean by vent. Chimney? Return air grille?
The BTU input and output ratings are on the same tag as the model #.
You take the size of your home in square feet and times it by how many rooms you have. A 70,000 BTU furnace will heat a house 1600 square feet.
If you mean an electric furnace then normally it is nichrome. a heating element in a heat strip is made of what type of wire
The heat exchanger is the metal wall or tubing that is heated up when the burners are ignited. The inside of the heat exchanger allows the toxic flue gases produced from the burners to exhaust out through the furnace flue. The outside of the heat exchanger is where the cold air passes over, beco…mes warmed, and is blown throughout the ductwork of the home. The heat exchanger is the only wall separating the toxic flue gases from the supply air. If a crack develops in the heat exchanger, there is a potential for carbon monoxide gas to leak over to the supply side and be blown throughout your rooms. Carbon monoxide gas is odorless. The human senses will not detect its presence. . Ron Ferrara- DHR Mechanical Services, Inc. (MORE)
If your home requires 2 million Btu of heat energy from the furnace what is the cost in dollars to heat the house with natural gas assuming 60 percent furnace efficiency?
If your home actually requires the 2MM btu then that is the output you need, if your furnace is 60% efficient then you would need 3,333,333 btu input to produce 2,000,000 btu output, There are 1000 btu per cubic foot of natural gas therfore you would burn 3333 cubic feet of gas to produce 2MM btu.

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 pr…ocess of heat transfer call convection. (MORE)

this question is very vague. furnaces over 100,000 btu's are rarely used in residential applications due to code restrictions. Anything larger requires fire dampers witch close the ducts off in the case of air over a certain temperature. more details are required.... a 5 ton air conditioner is hug…e by residential standards. obviously this is not compatible with the furnace you specified, and the numbers would only make sense somewhere like Florida. so equipment only at wholesale furnace $1000, A/C $5000 plus mark up, Plus installation. but here is the real deal you need a professional to size and install the equipment. There is a lot to this kind of work. In order to size a system you need to know what is the use of the structure( a home, business, computer data room, industrial etc) this effects code requirements as well the latent heat load of the space) size of the structure number of doors number of windows (are they single, double or triple pane) what kind of insulation and how much what is the fuel type I.E. nat gas, propane, fuel oil, electric what efficiency 80% 90% 92+% These are just a few of the reasons to have a professional do this, also there are licensing and permits and very specialized tools.

110,000 btu Since British Thermal Unit deals with volume rather than area, we need to know the height of the ceilings. The original answer probably (and sensibly) assumes standard 8' ceilings. Hate to sound like a nitpicker, but many of today's homes have at least one room with a "cathedral" or va…ulted ceiling. My previous home had "Saltbox" architecture; at one place in the great room (which comprised 1/2 the house's total square footage) reached a height of 42' sloping to 8' in front and 35' in the rear. The total square footage of the house was ~1700, where the cubic footage must have been almost 3 times that of a standard 1700 sf house. (MORE)

48,000 input or output? If 48K is the input to an 80% efficient furnace, than the output would only be 38,400.

The BTU output requirements of your furnace must be determined by heat load and heat loss calculations on the area that is heated. You should consult several HVAC contractors for estimates and recommendations. There are many factors that influence the BTU requirements of a furnace in any location.… (MORE)
I cannot really answer that depends on your insulation of walls heat leaks windows and so forth. NOT TO MENTION EFFICIENCY OF HEATING.
Impossible to answer. You need to have a Hvac pro, furnace man, do a heat calculation of you home and see if the BTU rating of your house matches the furnace supplied in it. Now even with a computer generated heat calc, there are way to many things in the home to come up with a perfect answer…. You should not turn up and down the thermostat in your home from day to night, the walls and furniture cool and then it takes longer to get them back to temp, its better to leave it on one temp.

Read the tag on your furnace for the input/output rating. American Standard and all other manufacturers make more than one size furnace.
The answer depends some on whether the 2000 square feet is all on one level, or divided into multiple levels. Typically 75,000 btu would be sufficient to heat 2000 square feet comfortably. Call a pro that will do a heat calc for the home. The worst thing you could do is follow a chart …that goes by sq footage. Big mistake. You have a heat calc done, this takes everything into account in the home. Size of walls, 2x4 or 2x6, what insulation is in the home, windows, everything that is important. Call several Hvac contractors and ask them what software they use, and how much for the calc, this is the right way to get the right unit for your home. (MORE)
It depends on the efficiency you are looking for and the metal workthat needs to be done. Contact heating and cooling companies to getestimates.
Cost of a furnace depends on the efficiency, the brand unit,transitions needed to be made, and the cost of a qualityinstallation. I recommend getting estimates from qualified andreputable HVAC companies.
yes it certainly can. Gas furnaces usually have a Fan/Limit combo switch. It has a helix coil that heats up and triggers the fan to start when it reaches operating temperature. When it gets too hot, it breaks the low voltage to the gas valve and shuts off the burners. As it cools off, the helix rela…xes and will fire back up. (MORE)
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..
In 2 of the 4 estimates for a new furnace for here in Southwest PA, the answer is yes. This house is a Cape Cod style and was built in 1950. But then 2 said I'd need over 100,000. So I'm wondering too! I am assuming you mean 80,000 output, not input. An 80,000 input rated at 80% efficiency only has… an output of 64,000. A 95% efficient 80,000 input will give you 76,000 output. Go with the people who did a proper heat loss calculation on your home since any two 1800 square foot houses could have different heating/cooling requirements. You also don`t want to oversize either. When I replaced mine 3 years ago I went from 100,000 to 52,000 and those are the input ratings at 80% & I`m doing just fine. (MORE)
You have to multiply the heat value of the fuel by the efficiency of the combustion unit. For instance, oil is 139,000BTU/gal, and many furnaces have an efficiency of 84%, so for each gallon of oil, you get 116,760 BTU of actual heat. Round that to 117,000 BTU to get the proper number of significant… digits. Different fuels have different heat values. Some have a range, such as wood pellets or firewood, depending on their species or source material. Furnaces range from 50% efficiency or so for a loose woodstove up to 95% or better for a sealed combustion direct vent propane wall heater. (MORE)
Your really are better off replacing the whole unit, there was a reason for the heat exchanger to have cracked or malfunction, ether for age or or a mechanical anomaly , you may have not addressed, as of yet.
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 regester…s. 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. (MORE)
It depends on the furnace, they come in different sizes. There should be a data plate on or in the furnace which lists the input and output rating.
Could be a few things, the house being cold, a broken temp sensor, disconnect between the sensor and the furnace/pump.

Why would a room finished after the house was built that is heated by a forced hot air natural gas furnace get air conditioning but not heat?
One possibility being that the air conditioner and furnace are separate so there may be duct/vents for one and not the other, if there is no duct/vent leading from the furnace to the room then the room wont be able to receive heat. Another possible cause is that there is a loss of heat on route f…rom the furnace to the room in question, this could be due to poor insulation or leaks in the junction of your ducts so cold air comes out as cold air and hot air also comes out as cold air. Also worth mentioning is that some older ducts have key toggles/dampers that you have to turn to direct the flow of air in different rooms, it is possible that the one that goes to the room in question is simply shut and thus blocking the air.

Heat exchangers are not indentical to furnaces. However, they do serve a similar purpose. Both heat exchangers and furnaces serve important individual purposes. They also aee ulilitzed for different devices.

It sets on top of the fire box and the plenum set on top of that
Many factors figure in other than square footage. Such as the height of the ceiling and number of windows. But, for most houses, 20 to 22 btu per square foot will do. 40,000 to 45,000 btu should do.
