because human cant breathe in the cold place. human need a heat place. but not too heat, (EDIT): Based on a Google search and a text book I've heard 100 W. The google search said that this is based on a 2000 calorie daily consumption averaged across the day, so the actual amount may vary. Heavy laborers consume about 4000 calories per day, so I could see using 200 W if the occupants will be continuously engaged in difficult physical activity. Perhaps more for both values since the above may average in sleep. The textbook I had told us to use 100 W for the sake of calculating the heat output of audience members in a concert hall, so that might be good enough depending on how much precision you need.
What else can I help you with?
A 100 watt light bulb produces 8 watt of light what happens to the other 92 watts?
The remaining 92 watts of energy is dissipated as heat, which is why incandescent light bulbs are not energy efficient. This heat is emitted from the bulb and contributes to the overall room temperature.
How hot is 1250 watts?
The heat output of 1250 watts depends on the application. In terms of a space heater, it can generate around 4,200 BTUs of heat per hour, which can effectively heat a small to medium-sized room. However, in terms of cooking appliances like ovens or stovetops, the temperature may vary widely depending on the efficiency and design of the appliance.
How many watts does it take to heat 200 square feet?
If you tell us the starting temperature and the finishing temperature and the specific heat of the material this 200 sq ft is made of then we'd have a chance of answering this one. But let's say that you're talking about a room (you didn't say you were but let's assume this), then a rule of thumb calculation, where the assumption is made that it takes 10 watts to heat a square foot of room, would show that you'd need 2,000 watts.
How much heat does an individual PC or PC server add to the room temperature for an average size room?
From the specific heat equation: c = Q / (m * T), the density equation: d = m / V and the power equation: P = Q / t we have: T = P * t / (V * d * c) where: T = temperature delta, in °C, P = heat power dissipation, in watts, t = time, in seconds, V = volume, in m³, d = density, in kg/m³, c = specific heat capacity, in J/(kg*K). Considering the air at 20°C we get: T = 8,257e-4 * P * t / V. Supposing a room of 50m³ and a heat dissipation of 100W we'd have a raise of 5,94ºC per hour. If we double the power, we double the increase in temperature. Doubling the room volume cuts the increase by one half. All that ignores some small changes in air properties which vary with temperature and the dissipation across the walls and windows in the room. The later is particularly important, as the calculations assume the room does not leak any heat. To get the right number one needs to know also exactly what amount of heat the computer generates. (It's safe to assume all power consumption from a computer is converted into heat.)
How much heat is generated by 1 watt?
According to some of the answers given here, and the mathematics involved in wattage, it seems to be that one watt equals 14.5°.Why? Because you can cram 1009 people into an 1809 sq ft room. You can heat a 400 sq ft room with a 1500w heater. Human Body temperature is 98.6°.
How many watts are required to heat a room of 100 square feet?
To heat a room of 100 square feet, approximately 10,000 watts of power are required.
How many watts of heat are required to maintain the desired temperature in a well-insulated room?
The number of watts of heat needed to maintain the desired temperature in a well-insulated room depends on factors such as the size of the room, the outside temperature, and the insulation quality. It is typically calculated using the formula: Watts (Room Area x Temperature Difference x U-Value) / Insulation Quality.
A 100 watt light bulb produces 8 watt of light what happens to the other 92 watts?
The remaining 92 watts of energy is dissipated as heat, which is why incandescent light bulbs are not energy efficient. This heat is emitted from the bulb and contributes to the overall room temperature.

How many square feet will 1500 Watts heat?
It depends upon how cold it is outside. However, my computer consumes roughly 500 Watts and can adequately heat my 960 cubic foot room when the temperature outside is around freezing outside. Your 1500 Watts of heating power should be just as effective at heating 3 times the volume, or 2,880 cubic feet. Presuming that your room is 8 feet tall, this means that it should be able to heat a room up to 360 square feet large.
How many watts does it take to heat 200 square feet?
If you tell us the starting temperature and the finishing temperature and the specific heat of the material this 200 sq ft is made of then we'd have a chance of answering this one.

What is the formula for heat loss calculations for a room?
The formula for heat loss calculations for a room is typically given by: Q = U * A * (Ti-To), where Q is the heat loss (in watts), U is the overall heat transfer coefficient (in W/m^2°C), A is the surface area of the room (in m^2), Ti is the inside temperature (in °C), and To is the outside temperature (in °C).
How many Btu's to heat a room over 100 degrees?
The number of BTUs required to heat a room over 100 degrees would depend on factors such as the size of the room, insulation, outside temperature, and desired indoor temperature. To calculate the exact BTU requirement, you would typically need to know the specific details of the room and use a heating load calculation formula.
What wattage space heater will heat a 280 square foot room?
A good rule of thumb is to aim for 10 watts per square foot, so for a 280 square foot room, you would need a space heater with around 2800 watts to effectively heat the space. However, factors like insulation, room layout, and outside temperature can also affect the heater's efficiency.
How many BTU required to heat a 250 sq ft room?
It will vary on the room type and construction. However you can assume you want 10-15 watts of energy per square ft. That would mean you want 2500-3750 watts total, which would be 8,500 - 12,750 BTU's (3.4 BTUs/Watt).References:How_many_square_feet_does_a_5000_BTU_heater_heathttp://www.diychatroom.com/f18/btus-watts-35066/
How much does a light bulb change the temperature of a room?
Very little, but it is noticeable, with a bright light in a small room. A light bulb puts out between 9 watts (energy-saving fluorescent light bulb) to approximately 100 watts (bright incandescent light bulb). Your average bar-heater, for comparison, puts out about between 1200-2400 watts.
