I get asked about propane generators for home use quite often. Most people who have this question want to know how much it might cost them to run a propane powered generator at their home.

This is a very good question because there are some significant advantages to using these devices but there are also some disadvantages that you should probably know about. The reason that they might use more fuel than other types of generators is simply a matter of physics.

The amount of energy that propane is capable of producing when it burns is simply less than both diesel or gasoline. In simple terms, based upon the laws of physics, you should expect to go through more propane than you would gasoline or diesel in similarly sized engines. This is simply a function of how large of a tank you have and how large the engine is. I wish I could answer this question in the kind of detail that I would like to but it really depends upon the size of generator that you plan to run.

For example, if I were to convert my small Honda EUi generator to run on propane, I could get by with a 20 or 30 pound tank. If, however, you would like to power a very large standby generator for your home with propane, you will need a much larger tank. Each generator will be different because they will have different engine sizes. It needs to vaporize into a gas in order for it to be able to combust in an engine that is powering a generator.

If the generator has a very large engine, it will have a much larger appetite for propane than a small one would.

In order for a propane tank to satisfy the appetite of a large engine, the liquid propane would need to be able to vaporize inside the tank fast enough to meet the demands of the engine. Because of this, very large propane tanks are often required for very large propane generators. Some people claim that propane generators are quieter than gasoline powered generators. There are many factors that determine how loud a generator will ultimately be. It has much more to do with the way the particular generator has been designed.

If you are interested in reading about some very quiet types of generators I suggest that you read my article called: What is The Quietest Generator For Camping? These types of gensets work basically the same as any other type of generator. The only exception is that instead of using a traditional carburetor they often have specialized carburetors that are designed especially for burning propane. In other cases, they have carburetors that have been converted to run on propane.

Another difference is that instead of pouring fuel into a gas or diesel holding tank, you will connect a hose coming from the propane tank to the generator.Just provide your zip code and how much of your home you want to back up all of it or just selected appliances and the calculator will do the rest!

Generator manufacturers typically have pipe sizing charts based on the generators output wattage and the distance from the fuel source.

Some manufactures recommend consulting with your installing plumber to make the right pipe size selection based on their knowledge and according to local codes. When a pipe is sized too small, the generator will not get a sufficient amount of fuel. This causes the engine to starve, preventing it from starting. The engine will try and try, but after several start-up attempts the unit will quit and sound an alarm to alert you there is something wrong.

There are many references for fuel pipe sizing, such as NFPA 54 — Natural Gas Fuel Code, Item which is a commonly used resource for certified plumbers. Some of these references can be found online. One of the best methods of installation is to oversize the piping, allowing sufficient flow to the unit and giving it more than enough fuel.

If an extensive amount of these restrictions are used you will need to refer to federal and local codes for proper sizing information. The generator needs to be the first item connected to the fuel source. A home standby generator will start operating at full load capacity allowing it to handle the large starting loads.

This can cause issues with pilot lights, such as heating systems, if you are not home to relight them. Other information that your installing plumber may need is the BTU requirements of the home standby systems.

Here are some examples of how to convert fuel consumption to BTU:. You can take that number and multiply 3. You are commenting using your WordPress. You are commenting using your Google account.

Henry Member Posts: November Piping It is simple, each and every LP or NG generator must have a maximum gas consumption rating on its id tag.

Before installing the piping, we check the specs for the generator either in the manufacturers website or shop drawings. You then use your gas code for proper sizing and not the manufacturer's minimal pipe sizing! ALso beware and don't assume that all generators will work between 5 and 7 inch H2O!

Some will need 11 inch. Tim McElwain Member Posts: 4, By separating the generator from the house piping system you can prevent surges when the generator kicks on and possible pilot outage.
