Propane Calculator

 

 

If you are planning to use a propane generator during a power outage it’s good to have an idea of how much propane the generator will need.

Fuel is often one of the first things to sell out during a disaster as most people turn to their generators to power electrical appliances.

Propane generators are great for emergency preparedness because propane is more widely available than gasoline during times of emergency.

The propane calculator below can estimate how long your generator will run on propane.

The calculator takes two inputs, the estimated power usage per hour (in watts), and the estimated total time of power usage (in hours).

The propane calculator will also estimate how long typical propane cylinders and tanks will last based on your energy consumption.

 


 

 


 

 


 

I have a propane generator rated at 2000 surge watts and 1350 running watts Max.

Using a 1000 watt running load it will run for approximately 21 hours on a full 20 gallon cylinder of propane.

 


 

 


 

Propane Won’t Flow In Cold Weather (At What Temperature?)

 

Propane may not flow at 29 degrees F and the source for that problem will be opening the valve too quickly.

If you are camping in cool weather, the drop to below freezing can happen suddenly and catch you by surprise.

When it does, open the valve slowly so you can run your grill or propane generator.

 


 

A full 20 lb propane tank contains up to 4.7 gallons of propane.

The 20 lb tank is the most common propane tank size for residential use as it is large enough to be a primary fuel source for most applications. They can fuel BBQ, generators, and camp stoves.

An empty 20 lb tank weighs 17 lb. And a full tank weighs around 37 lb.

 


 

Propane tanks were icing up. This video shows how to fix the problem. The tanks don't ice up anymore. Below 29 degrees F a tank will ice up and you will not be able to use it.

 

 

The key is keeping the frost off the tank as it insulates, creating a postitive feedback and slows the heat transfer through the tank wall. The water is apparently adding just enough heat energy to keep the tank from building frost.

Others had success wrapping the tank tightly in that bubble wrap radiant barrier. It’s the bubble wrap that helps there keeping the humid air off the tank walls.

 


 

 


 

The Metrics: Gallons as the Grilling Currency

Gallon capacity will dictate the extent of your grilling sessions. Its like a fuel gauge for your culinary endeavors.
