Btu rating of each appliance.
Gas appliance btu usage.
Calculating propane gas consumption is based on the burner size.
1000 btu 1 cfh.
A btu or british thermal unit is the quantity of heat required to raise the temperature of one pound of water by one degree fahrenheit.
Natural gas contains 1 075 btus per cubic foot.
Gas fireplace numbers are based on burning gas logs as opposed to using a gas starter fireplace at 60 000 btu hr over 120 hours of annual operation.
For example if a burner uses 22 875 btu per hour it will last 4 hours on a gallon of propane which contains 91 502 btu.
Natural gas is measured in therms or btus.
You simply divide the energy content of the propane by the burner consumption.
91 502 22 875 4.
Natural gas is measured in therms or btus.
Converting to lp gas may change the btu rating on gas dryers.
For example a low flame on the stove may only use 400 btus even though the burner might have an 18 000 btu capacity.
Step 2 determine the burner output in btus per hour from the appliance sticker or user documentation.
In general the lower the flame the lower the btu output and the higher the flame the higher the btu output.
A therm is a measurement of the amount of heat energy in natural gas equal to 100 000 btus.
Min pressure inches water column.
Propane contains 2570 btus per cubic foot.
We hope these tables charts will help you to better estimate how big and powerful generator you will need as a backup source of power.
The current charge for natural gas from wps is 0 4166 per therm.
Top load and front load gas dryers are rated for 22 000 btus of heat per hour btuh for natural gas.
A therm is a measurement of the amount of heat energy.
Multiply the burner efficiency by the energy content of the gas being used.
Pool heater numbers are based on using 300 000 btu hr over 120 hours of annual operation.
Furnace numbers are based on an average gas furnace with a 92 percent efficiency rating.
That is why we have decided to create this list of rough estimates of wattage consumption of most common household appliances that people want to keep running at all costs.
