Here’s proof that recycling can be both useful and clever: a propane tank turned wood stove. Its small size makes it easy to move and ideal for quick heating or simple cooking.

With a fitted chimney for ventilation and a door that controls airflow, it works surprisingly well while costing almost nothing to make.

This little unit is a reminder that with some effort, old metal can live again with a brand-new purpose.

Materials Needed

• 1 empty propane tank (20 lb, thoroughly purged and cleaned)
• Angle grinder with cutting discs
• Welding machine & safety gear (helmet, gloves, apron)
• Steel pipe for chimney (4-6” diameter, about 18-24” tall)
• Metal sheet for door (approx. 6” × 10”)
• 2 hinges (heat-resistant)
• Knob or handle (ceramic or heatproof)
• Grate (metal mesh or expanded steel)
• High-temp paint or stove polish (optional)

Step-by-step Guide

Step 1: Begin by safely purging the propane tank. Remove the valve, rinse with soapy water several times, and leave it open outdoors for at least 24 hours.

Step 2: Cut an opening near the bottom front to form the stove’s firebox door. Make sure it’s large enough to load wood but not so big that it weakens the body. Then smooth sharp edges with your grinder.

Step 3: From your metal sheet, cut and shape a door. You can attach it to the tank with hinges and fix a ceramic or heatproof knob to the front for easy use.

Step 4: Inside, weld or bolt in a small grate made from expanded steel. This lets air flow under your burning wood, keeping the fire stronger.

Step 5: Cut a circular hole on top of the tank and weld in your chimney pipe. This draws smoke upward and out, improving airflow.

Step 6: Test burn with small kindling first, making sure the chimney drafts well and no smoke leaks out the sides.

Step 7: Optionally, finish by coating with high-temp black paint or stove polish for durability.

Tips: 

When I tried a build like this, I realized that keeping the chimney tall enough is essential for good draft. Also, a small air vent near the base makes a big difference for controlling burn speed.
