How do I figure the number of BTUs a heating device puts out if I only know the temp and the time it operates?

Question

I have a device that puts out a consist tempeture when it is in operation. I would like to know how to convert the time and temp during operation to a BTU per time period.

Answer 1

If it is electric heater look at the consumed power which you can convert to BTU
1 kilowatt = 0.947 817 121 Btu/second

Answer 2

BTU (British Thermal Unit): The quantity of heat necessary to raise the temperature of 1 pound of water by one degree Fahrenheit at a specified temperature and pressure (from 59 Fahrenheit to 60 Fahrenheit at an atmospheric pressure of 29.92 inches of mercury).

As a point of reference, the heat generated by the burning of a wooden kitchen match = 1 BTU.

Simply knowing the temperature of output and the duration of operation will NOT translate into a number of BTUs (or BTU-per-time period).

Answer 3

it sounds like you need to refine your question.

for example...

if you have a completely closed system with no heat in or out and your device is off, then the energy of the system (and it's temperature) would remain constant and the number of BTU output/time = 0

if you have an open system with energy (in the form of heat) being removed and the system is at constant temperature, then your device must be adding an equivalent amount of energy. IE BTU output/time >0

if your open system has heat being added (like a car in the hot sun), then your device must remove energy to maintain constant temperature BTU output/time < 0

if you add energy to a closed system containing water and the water say boils, then you will add energy to the point where the water is all vaporized and the temperature will remain constant. BTU output/time >0 while temperature is constant.

So you need to find out what other energies are being added or removed from the system, what the temperature is, and what materials are in your system.

Answer 4

Sometimes good people out number bad people but it is also correct that sometimes bad people out number good people. Nowadays politicians in most of the countries are corrupt and are in majority.

Answer 5

You do not have enough data to make the calculation.
