What’s Your Backup Plan B

On the morning I wrote this article, it was a bitter 10 degrees Fahrenheit outside.

It was so cold that morning; my Labrador retriever refused to brave it.

Deciding to take a pass and “hold it” in hopes of a warm-up.

He was disappointed…

Yet I was comfortable, typing away at my computer keys and sipping a warm coffee in my warm 71 degrees home.

It’s times like these that I realize just how fortunate we are today.

Heating, indoor plumbing, motor vehicle transportation, refrigeration…it’s amazing.

I try not to take it for granted…

That’s why I often wonder what life would be like without these modern conveniences.

The easiest way to imagine this is to think about our electrical grid going down for an extended period.

Let’s pretend it goes down for a week in the dead of winter.

  • What would that be like?
  • How would you handle that situation?
  • What’s your plan B?

And it’s not hard to imagine because it happens to millions worldwide every winter.

So it’s your responsibility as a self-reliant adult to have a backup heat source strategy.

Maybe you already have a fireplace, wood stove, or tent stoveGreat!

If this is you, then you already have an excellent backup heat source as long as you have a large pile of seasoned firewood.

But not everyone has an expensive wood stove, or you’d prefer multiple backup options.

Some attempt to build cheap clay pot candle heaters, but they’re only a short-term fix.

The bottom line is:

Heat (or lack of heat) is a major concern for our health and well-being.

That’s why you should consider getting a backup kerosene or propane heater.

↓ Storing Fuel for Preppers

With propane or kerosene heaters, you can supplement a mobile heat source for special situations.

Such as:

  • heating specific rooms that tend to be cooler
  • heating garages when working on a vehicle in the winter
  • using them to heat an RV or tent for winter camping

And if you’re considering living off the grid, you’ll need to think carefully about all your heating options, from cost to reliability.

Finally, running a supplemental heater on cold days is often more cost-effective when heating your home than cranking up your thermostat.

And the two best fuels to consider for backup heat generation are

  1. Kerosene
  2. Propane

Now, some people will argue the merits of electrical heaters, but those rely on the power grid.

So I tend to discount that option immediately.

You want to diversify your fuel sources for emergencies,

But which is best? Which type of heater should you buy?

The honest answer depends on what you are trying to accomplish.

So before we can figure out which one’s the best for you, we need to break down the pros and cons of each fuel.

To do that, let’s cover the following three categories:

  1. Availability
  2. Price
  3. Storage / Safety

Propane Vs. Kerosene (Pros and Cons)

1. Availability Of Propane Vs. Kerosene

If you can’t find where you live, then what’s the point?


You can purchase small tanks of kerosene from places like home improvement stores and camping stores.

But these small tanks are a poor financial deal.

You should look for a nearby gas station with a kerosene pump to find the best deal (i.e., the best price).

In some locations in the States, this might not be a readily available option.

So do some research online using google maps or forums and find your nearest kerosene pump.

If you’re far from a kerosene pump, you can either stock up the next time you’re there or choose a propane heater instead.

Here’s a post that lists gas stations that sell Kerosene (and those that do not).


For the most part, propane tanks are more readily available for purchase or rental than kerosene.

The main reason is the popularity of using propane for gas grills.

So many home improvement, grocery stores, convenience stores, etc., have propane tank rental programs.

But this option is not ideal for large-scale storage.

Plus, you’ll want to buy your propane in bulk for better pricing.

To do that, you’ll need a large propane tank to store it (more details shortly).

So you’ll want to call your nearest propane delivery company and see if they service your area.

Oh, and while you have them on the phone, get an updated bulk rate price…

2. Kerosene Vs. Propane Prices

In general, the economic laws of supply and demand determine the price of fuels.

They are not stable and go up and down.

The current price of these fuels on the date of writing this post is as follows:

  • Kerosene – $5.93/gallon (updated 3/08/2023)
  • Propane – $3.50/gallon (updated 3/08/2023)
Note: Prices will vary based on your location, so check your local prices for accurate information.

So on a per-gallon basis, propane seems like the obvious winner.

But that’s only the first part of the story.

The price per gallon matters, but what REALLY matters is the Cost Per BTU.

This is because 1 gallon of kerosene has a different amount of potential energy than 1 gallon of propane.

So we must consider this energy potential to figure out which one is the better value.

  • Kerosene has roughly 135,000 BTUs of energy potential per gallon
  • Propane has roughly 91,333 BTUs of energy potential per gallon

So now we can figure out what matters; Price Per BTU. 

So with simple math (divide the price by the BTUs and times that by 1000).

  • Kerosene – $0.0439 per 1,000 BTUs of energy
  • Propane – $0.0383 per 1,000 BTUs of energy  22779  26109

So there we have it; currently (3/08/2023), you get 14.6% more BTUs of energy for your dollar with Propane than you do with Kerosene.

But again, prices vary, and you should check the local kerosene pump prices and call your nearest propane vendors to get actual per-gallon prices.

Over the years, the “Better Deal” has flipped back and forth depending on supply and demand.

But you’ll need to do that math yourself on the day your read this.

3. Storage Life / Safety Of Propane Vs Kerosene

Kerosene is one of the safer liquid fuels to store and use.

The biggest reason for this is that it’s much less explosive than other popular fuels (i.e., gasoline).

In general, Kerosene requires a wick for it to ignite.

So if you light a match and drop it directly into a bottle of kerosene, it won’t ignite, unlike gasoline which will explode.

Another benefit to kerosene is how long it keeps in storage because I’m a fan of stockpiling.

But with many fuels, it’s a challenge to store them long-term.

Which means you have to add additives annually or rotate.

But with kerosene, as long as you store it in a quality container, it will be useful for years or even decades.

The best way to store a large amount of Kerosene is to get a few large 50-gallon drums (like this one) with good clamp seals.

You may also want to put these drums into a secondary containment trough for any drips or leaks.

Another consideration with kerosene is that even in 50-gallon barrels, you’ll still be able to haul it.

If you plan to bug out, this might be an important aspect.

Sure, you’ll need a truck bug out vehicle or a survival trailer, but it CAN be done.

If you only plan on storing a limited amount of propane, you might get away with purchasing a few smaller 11 lb. propane tanks.

However, if you want to store large amounts of propane, then you’ll want a large propane tank.

You often see those large metal tanks in the yards of many old farmhouses in the Midwest.

They are bulk propane storage tanks and an excellent way to store a lot of propane safely.

While propane is a gas and its fumes are very flammable, storing it in a large propane tank is safe.

The tank and valves are designed to store large amounts of propane above ground in your backyard. It’s low risk.

And the propane will keep indefinitely as long as the tank and valves are in good shape.

But that’s the rub; large-scale propane tanks are not cheap.

And used tanks may or may not be in good enough shape to trust.

Another downside of a large propane tank is that it’s not mobile.

If you plan to bug out when things go south, then a large propane tank would not be a good investment for your long-term survival plan.

So again, it depends on your survival goals, but both kerosene and propane are solid long-term options.

Kerosene Vs. Propane Heaters

If you want a backup heat source for prolonged power outages (or supplement heat) , then I believe you should go with kerosene.

It’s relatively straightforward to store; it lasts a long time; it’s a safe fuel to use, and it’s reasonably priced.

Even if it’s not readily available near your location, you can plan an occasional trip to a kerosene pump and load up as needed.

However, propane is also an excellent choice for prolonged power outages and energy backup.

But you’ll need to invest in a large propane tank to store it at scale. But if you already own one, or can get one at a good price, then propane is a solid way to go.

The bottom line:

The good news is that you can’t go wrong whichever you decide.

For some, kerosene will make more sense, but propane is the way to go for others.

The key is for YOU to do some research to decide which is right for YOU.
