is a black woodstove or a white woodstove more effective in heating a room?

Dark substances convert more light energy to heat energy, but also release that energy more quickly.  The heat energy absorbed would be the same in each if they are same in every other way.  So, it depends what you mean by more effective.  Once the fire is out, the black one would give off more hear, but not for as long.  The white one would stay warm longer, but wouldn't give off as much heat.

120W would be brighter, and here is why:\n120W light bulb would have higher temperature (rough argument: dQ/dt= c*m-sigma*T^4, at equalibrium c*m = sigma*T^4 =P =V*I, where c= heat capacity per mass), and by Planck's law of black-body radiation will emitt more visible light than Infra Red light, so it's more efficient in producing visble light for the same energy than 2x 60W light bulbs. Great question.

not really, cottonwood is a softer wood, as i grew up with a wood stove in the house the best woods to use for this are the hard woods, ie: oak, maple, hickory, but you need to use what you have available, we always burnt the hardwoods, we would always cut wood in the warmer winter days or late fall. then stack it in the shed or under a tarp till the following year, so it had time to "season" (dry) the reason for the hardwoods is that they give off the most heat, and burn the longest due to the higher density.

white is better as it basically reflects the sun so u stay cooler where as black absorbs the sun which is why u get hotter. Light colors jsut keep you cooler thats all there is to it

Generally speaking Natural Gas has been the cheapest for the past years. However now with the electric heat and air at 90% effeciency the centeral heating is the same cost to run as gas, and in some cases less with a well insulated home.  Energy for the stove is still less costly with gas. The Propain Gas costs more than Natural Gas. Heating Oil is a low cost now, but does not have the efficiency of the modern highly efficient electric heat pump centeral heat and air. Even cheeper is to put individual gas heaters in each bedroom and one in Living room and Kitchen. Zoning like this saves the most on home energy.Do not forget that summer will come and Air conditioning is needed aswell.Therefore a combined Airconditioning and heating system of high efficient electric is the best solution for modernization. Seperate gas heaters is the cheapest heat.

Carpeting is less expensive than hardwood flooring.  As for making the home warmer - that must mean aesthetically, not temperature wise.  Neutral is a selling point because any furniture will go w/ it.

I have electic heat and it can be very costly.  But I also have a wood burning stove.  I average about $100.00 a month in electic including tv's, freezer, refrig, lights, and etc.

Probably you would not notice much of a difference. In fact if you used electric heat you wouln't notice any difference at all (at least in the winter). The reason is the amount of electricity an appliance uses is pretty much proportional to the amount of heat it generates. If you really want to save electricity get rid of your oven, refrigerator, toaster, hair dryer, basically any appliance which generates a lot of heat.

I have the same problem with my electric stove.  Overtime, (just like everything) they got worn out and what my neighbor did was replace the entire unit...thus giving her an excuse to remodel the ktichen.  However that is WAY too expensive...Is it that every plate does not heat up as much as it used to?  Now my family's remedy is to use the plates that we hardly used before (the ones in the back for example).  I haven't taken any courses in engineering but I would love to explain why if I had :(  I agree with the previous post, call a professional in electrical appliances.

Well, a blue flame is the most efficient burn and the hottest no matter what your combustible matter is.  At what temp that is, I don't know.

dont know about q1\n\nQ2 They push the heat out at the floor because the coler air is at the bottom of the floor and since hot air rises then then the hot air will circulate more by rising through the cooler air and warming it up as opposed to being near the ceiling where the hot air would just stay near the ceiling.\n\nQ3 The smoke is usually heated and composed alot of carbon monoxide. The heated smoke will rise as it is warmer than the cooler air around it, once it cools down to the temperature around it than it will usually fall back down since carbon monoxide is heavier than air and that it will also combine with other elements in the air.\n\nQ4 A continuous hot water system works better because the the hot water is circulated throughout whatever system it is heating, such as air or other water then return back to the heater (furnace) not cooled completely and still retaining some of the heat it originally had and since it is already warm it takes less energy and time to heat it back up to its original temperature.

Yes, darker colors absorb heat quicker.\n\nFor example, you would not want to wear a black shirt outside when it is hot out.\nIt would be smarter to wear a white shirt, because it would not get hot as fast.

The one that I would be most interested in using is geothermal energy. There are some really exciting new applications of geothermal energy for use in heating and cooling homes that essentially involve putting a heat pump deep enough underground that it reaches the soil zone where the temperature is constant year round. This results in having a source of heat in winter and a heat sink for cooling in summer. Every house should have one!!!\n\nSadly the new energy plan proposed by the administration cut geothermal energy research to ZERO.

Fire\n\nInvention? Or discovery? *shrugs* But I'm thinking most of all we need and use just wouldn't be around without this heating component. Just a thought.

Radiation caused by temperature is often called "Black-Body Radiation." Perfectly Black Bodies are the best type of objects to absrob heat - as most of us know if you wear a black T-Shirt in the sun, as compared to a white one!\n\nI quote to you a fundamental statement of black-body radiation "The best possible absorber of radiation is also the best possible emitter of radiation."\nThis is because the efficiency of a black body does not depend on whether radiation is being emitted or absorbed.\n\nA black radiator is much more efficient than a white radiator because it can absorb (and therefore radiate) better.

try comparing (energy sources/cleanliness/behavior) betwween two things

White is 7 deg. f. cooler than black. White paint can be loaded with titanium oxide which has better heat transfer properties.
