Choosing Between a Diesel and a Propane Whole House Generator

whole house generator diesel vs propane

The choice of which whole house generator to purchase can be a difficult one, especially when you consider the range of features and benefits each provides. It can also be difficult to decide which one will suit your particular needs and requirements. Here are a few things to keep in mind.


Whether you’re looking for a backup generator to keep you and your family comfortable during power outages, or just need some extra oomph in your home, choosing between a propane powered and diesel generator can be a bit of a challenge. However, both offer their own set of advantages and disadvantages.

Propane is a cleaner burning fuel than diesel. Diesel is a petroleum-based fuel that is relatively cheap to buy and run. It also has a long shelf life, meaning you won’t have to worry about running out of it for months on end.

The cost of whole house generators depends on how much energy you need, the size of your home, and the type of generator you choose. Generators range from $4000 to $15,000. You can also add on other costs such as fuel and installation.


When you are choosing a whole house generator, the question of which fuel to use is important. While both diesel and propane have their advantages, the best choice for you will depend on your needs.

The main benefit of propane is that it produces less greenhouse gas per gallon than gasoline. Propane also burns cleanly. This helps to reduce particulates and nitrogen oxides.

Diesel, on the other hand, produces more CO2 than propane. It is also more expensive. In fact, diesel engines are banned from operating in certain locations because of toxic emissions.

Propane is not only cleaner and cheaper, but it also offers resilience benefits. This makes it a better option for cold environments.

The energy produced by one gallon of propane is 27 kWh. This is more than enough to power a typical home for an hour.

Life expectancy

If you need a backup generator for your home, you may be wondering whether to get a propane or diesel fueled genset. Both are very reliable, but they offer different benefits and disadvantages.

The first difference is in price. A propane genset costs five times more than a diesel genset. It is also more expensive to store. You will need to buy a propane tank and install it. Diesel generators are more affordable in fuel, but they have higher installation and maintenance costs.

Propane burns cleaner and produces less carbon monoxide than diesel. They are also odorless. However, they have shorter life expectancies than diesel gensets.

While propane is more environmentally friendly, it has a lower efficiency rating. This means it provides less energy per gallon than gas. In addition, it has less BTUs.


If you’re wondering what type of generator you should get, it’s important to consider the differences between diesel and propane. Both provide reliable, affordable backup power, but there are some drawbacks.

Diesel has a higher energy density than propane. This means it burns through faster. However, it’s harder to find and more expensive to buy.

Propane is cheaper, but it has a low energy density. When it’s burned, it creates more particulate. It’s also less efficient. Compared to other fuel sources, it produces less greenhouse gases.

Both propane and diesel can be dangerous if they’re improperly handled or stored. For this reason, you should always use caution. In fact, you should never use a propane generator indoors, and you should never store it in a sealed room.


When it comes to choosing a whole house generator, you have two choices: propane or diesel. They both have their advantages and disadvantages.

Propane is a cleaner-burning fuel. It emits fewer greenhouse gases and particulates than diesel. The fumes are odorless, but they can be dangerous if not handled properly. Diesel, on the other hand, has less energy density and is not as clean burning.

If you live in an area with a lot of pollution issues, you may want to look into propane as a solution to your power needs. However, you should also keep in mind that these generators are not as durable as diesel systems.

Another reason to look into propane is the cost. It is cheaper than diesel. In addition, propane is a more reliable fuel.
