Propane vs Diesel Generators in Chester County, PA

What You’ll Learn

Should I choose a propane or diesel generator for my home?

Both will restore your power, but propane wins for home use: it burns cleaner, runs quieter, has an unlimited shelf life, and stays available during outages because suppliers can deliver without electricity.

Diesel is harder to store long-term and can’t be pumped from stations when the power’s out.

How do you know, though, what type of generator to purchase? What works best with propane vs. diesel generators in Chester County, PA, in particular?

Propane vs. Diesel Generators in Chester County, PA

Chester County is subject to any one of a handful of natural disasters. Thunderstorms, blizzards, windstorms, and tornadoes are just a few of the things residents have to endure. Generators have become a necessity. 

Both propane and diesel generators will fire the lights up and get your power back on. When you look at the two types of generators side by side, you can better see which one will best serve you in your time of electrical need. 

Pros of a Diesel Generator

When people think of generators, diesel generators are the traditional and usually first image. You can almost hear the engine rumble and smell the diesel exhaust. Here are a few of the benefits of diesel over propane. 

Easily Obtainable

While most people will keep their fuel stocked up for disasters, you can still run out.

Diesel is one of the most easily obtained fuels because so many people use it. 

Just find a working gas station with diesel, and you have what you need.

So whether you’re talking about a diesel generator for an RV or a home, you can easily obtain diesel. Not all stations carry propane. 

If you cannot drive your generator to the fuel station, many stations offer delivery service that brings your fuel to you. 

Flammability and Safety

Of all the possible generator fuels, including propane, diesel is the least flammable. Diesel has a narrower flammability range. 

Cost

Diesel is comparable in cost to propane. It’s worth noting, though, that because generators are designed for applications off the road, you may operate them with dyed or farm diesel. Dyed diesel costs less than traditional diesel because you do not have to pay road tax on it. 

Better Engine Operation

Diesel-fueled engines can operate in subarctic conditions with a fuel additive. Furthermore, you can run the engine for a long time even when your load is light.  

Cons of a Diesel Generator

Not everything is roses with diesel generators. Here are the downsides. 

Smell and Sound

Diesel generators emit an occasional odor. You have to get over this if you’re using a diesel generator. 

Plus, diesel generators emit a much louder, continuous sound as they run compared to propane generators. 

Shelf Life and Availability

Diesel has a relatively short shelf life compared to propane. Without additives, it lasts 18 to 24 months. 

Plus, you may not be able to find diesel during a power outage. The diesel will be at the filling station, but if the station loses power, they can’t pump it into your generator or fuel cans. 

Storage

You need a significantly large diesel tank to store enough for a lengthy emergency. When a tornado takes out the power for days on end, you will need a great quantity of diesel for your generator. 

With that said, the short shelf life prevents you from stocking up for years on end. 

Emissions

Nine states have emission laws that will affect your diesel generator. These states prohibit diesel engines from operating over a specified number of hours each year. 

The emissions from a diesel engine are far more harmful to the environment than those from a propane generator. 

Propane Generator Pros

The benefits of propane generators are countless. Here are just a few of the many reasons people choose propane generators. 

Cost

While diesel may cost less on demand than propane, you can purchase propane in advance with a pre-buy plan. Ultimately, this saves you money because you do not have to risk inflated prices during a crisis. 

Emissions

Propane burns clean. It produces fewer pollutants compared with diesel. More precisely, it generates less carbon monoxide than other fuels. 

When you’re concerned about fumes, a propane generator is a good choice. 

Sound

Propane generators are quieter than diesel generators. If you’re planning to take your generator camping and want to enjoy the sounds of nature, you’ll want as little noise as possible. 

Shelf Life

Propane has a longer shelf life than diesel. You keep your propane in a tank on your property, similar to what you’d have with diesel.

Unlike diesel, though, the propane doesn’t break down, even if you only use it a couple of times a year. 

Plus, you can store propane in either small 5- to 10-gallon cylinders or large tanks. You can even use an underground propane tank to save space. 

Availability in an Emergency

You don’t need electricity to obtain propane like you do to pump diesel. Gas stations cannot pump diesel during area-wide outages. Propane suppliers, though, can still deliver propane to you.  

Propane Generator Cons

Propane has few downsides. Availability and safety top the shortlist. Here is why. 

Availability

If you’re using a mobile generator and are in a remote area, you may have a difficult time finding a propane supplier. 

Safety

While propane burns cleaner, it poses an explosion risk if ignited. Individuals with a propane generator should have the generator inspected annually. 

If your propane company does not conduct inspections, switch to a propane company that does.
