Best Single & Double Burner Propane Forges + Buyer’s Guide

A blacksmith adjusting his propane forge in a workshop.

When deciding on a propane forge for your blacksmithing hobby, it’s important to have a clear idea of what your preferences and long-term goals are.

If not, you may wind up with a forge that underperforms, is poor quality, doesn’t reach optimal temperatures, or is too small for your projects.

As you review below the best choices available, carefully consider the following:

  • How small or large most of your projects will be.
  • What shape you prefer – cylinder, square, or rectangular.
  • The maximum temperature you’ll need for your work.
  • Safety features, such as doors and quality valves.
  • Overall dimensions that will fit your workspace.

Best Choice Overall

After looking at all the features and specs for the propane forges that made my top 7 list, I’d say your best bet is the Simond Store Blacksmith Single Burner.

Propane Forges Explained

Propane forges are gas-powered forges that hook up to propane tanks similar to a barbecue. 

Usually small enough to fit on a table or desk, propane forges are rectangular, oval, or round in shape and often don’t have doors.

For many, you can extend a working piece of metal straight through to the other side.

These open ends allow for airflow through the forge, which keeps the flames from going out.

Features

Propane forges are made of thin metal exteriors and contain insulation all along the interior to create incredibly hot environments.

Most forges can reach interior temperatures of 2,000-2,600 degrees Fahrenheit.

Purchases frequently contain fire bricks that reflect heat onto the working metal for greater temperatures.

As fire bricks are made from materials with low thermal conductivity, such as ceramics, their use increases efficiency inside the chamber.

Safety

Safety is a huge issue with any kind of forge, but anyone using a propane forge needs to be particularly alert and careful.

Propane forges need good ventilation to prevent carbon monoxide poisoning. Gas leaks are also a risk if the valves or tubing happen to malfunction.

Similarly, the flame that burns is widespread and can take beginner blacksmiths by surprise.

Being aware of how the forge lights and how to avoid the flame is crucial to avoiding singes or burns.

Propane Versus Coal/Charcoal Forges

Propane forges are more commonly preferred over coal or charcoal forges, particularly if you are a beginner.

While propane forges are louder and have risks of gas leaks, coal forges are more difficult to control and contain dirtier elements.

Coal will burn hotter than propane but requires regular cleaning of the forge, which can be tedious.

Furthermore, there is more equipment required for propane forges, although propane is easier to obtain these days than coal or charcoal.

All in all, there are many advantages and disadvantages to both, but if you’re looking for a simple forge solution, propane forges require less skill to maintain.

Single Burner or Double Burner Forges

Propane forges have the option of one or two burners. A single burner forge contains a single propane hookup where the heat will enter the forge from a single entrance point.

This allows for a smaller forge and easier metalworking.

Beginners benefit from single burners because this concentrates the heat at a specific point, which is easier to manage.

Single burners are also ideal for small work that is also typically done by someone learning to forge.

A double burner forge is larger, more expensive, and usually not necessary for beginners or small metalwork.

With a double burner, heat is applied through two entrance ways into the forge.

A single propane tank is used to supply fuel, which flows to two separate burners to be lighted inside the forge.

Double burner forges accommodate larger metalwork pieces. They keep the entire forge hot so that longer pieces won’t cool in the air beyond a single burner.

Related Questions:

How Much Propane Does a Forge Use?

If your forge is functioning with 8 psi, a full 20-pound propane tank will last about seven to eight hours. Generally, forges work between 3 to 10 psi.

How Hot Do Propane Forges Get?

The interior heat depends on the forge, but the average maximum temperature for a propane forge is 2,300 degrees Fahrenheit.

Does a Propane Forge Need a Blower?

Propane forges do not need blowers to function. They are atmospheric, so they do not require additional air. 

Conclusion

Really, I don’t think you’ll be disappointed with any of the forges presented here.

Overall though, I think the Simond Store Blacksmith Single Burner is tough to beat.

It’s got it all: affordable price, quality parts, ideal size, steady temps, and easy setup. The convenient tong stand is the icing on the cake.

If you have your heart set on a double burner, I’d go for the Hell’s Forge Double Burner.

With a length of 19 inches, there’s plenty of room to heat long stock even with the firebricks in place.

The option of only using one burner at a time means that you’re almost getting two forges in one, which adds to the value tremendously.

Quality construction. Excellent heating. Versatile. Packaged carefully (even includes brush for applying cement!). You’ll love this beast!
