Make a stove with your own hands: cheap and effective heating

Why should you make a stove yourself?

A stove (often also searched as “DIY stove”, “how to make a DIY stove”, or “how to build a stove yourself”) is a simple yet effective heater that can be built from available materials for heating small spaces, greenhouses, or cooking. The main advantages of such a homemade stove are:

1. Low cost. Making a homemade stove is significantly cheaper than buying a factory-made stove.
2. Economy and efficiency. A properly designed and assembled stove can effectively heat a space while consuming relatively little fuel.
3. Simplicity of design. You do not need complex tools or materials. Many people choose to make a DIY stove because it can be easily constructed even without deep construction skills.
4. Versatility of use. It is not only for heating but also for the possibility of cooking directly on the stove’s surface.

In this extended step-by-step guide, we will discuss how to make a stove from bricks or metal, provide tips on material selection, safety, and stove maintenance.

Types of homemade stoves

1. Brick stove

   • Uses fireproof (refractory) bricks or regular solid bricks.
   • Holds heat well and is suitable for long-term use.
   • More suitable for stationary installation indoors or in the yard (for example, a summer kitchen).

2. Metal stove

   • Most often made from a thick-walled barrel, gas cylinder, or sheet steel.
   • Heats up faster but also releases heat to the outside more quickly.
   • Can be more mobile, easier to make and transport.

3. Combined stove

   • Combines a metal frame with a brick or refractory insert.
   • Such a design can be optimal for quick heating and retaining heat for a longer time.

Depending on your goals (to heat a small room, garage, summer kitchen, or even cook food), you can choose any of these types or modify the design to suit your needs.

Materials and tools

For a brick stove, you will need:

• Bricks (solid or used, to reduce the cost of the construction).
• Fireproof bricks or refractory blocks – withstand high temperatures and ensure durability.
• Refractory clay or heat-resistant cement – for joining the bricks.
• Metal pipe (chimney) – preferably made of thick steel or a special chimney module.
• Tile or thick steel plate – to create a surface for cooking food.
• Tools: hammer, mallet, trowel, level, angle grinder (if necessary), tape measure, protective gear (glasses, gloves, respirator).

For a metal stove:

• Steel sheet at least 3 mm thick or a suitable blank (barrel, gas cylinder).
• Welding machine and consumables (electrodes, etc.).
• Corners or profile pipe for the frame (if additional reinforcement is needed).
• Chimney pipe made of thick steel or a ready-made chimney pipe.
• Angle grinder with cutting discs, electric drill (if making holes).
• Personal protective equipment (welder’s mask, gloves, glasses).

Step-by-step instructions for a brick stove

1. Choosing and preparing the location

• Determine where your DIY stove will stand. The location should be safe, with enough clearance from walls and easy access for the chimney.
• Ensure that the floor or base can support the weight of the future construction.

2. Pouring or preparing the foundation

• For a stationary stove, it is recommended to make a small foundation.
• Dig a shallow trench (20–30 cm), and create a sand cushion 5–10 cm thick.
• Pour concrete or lay several rows of solid bricks on a cement-sand mixture.
• Level the surface to ensure it is horizontal.

3. Laying the base

• Lay the first row of bricks around the perimeter of the future stove.
• Use refractory clay or heat-resistant cement. The mixture should be dense and withstand high temperatures.

4. Forming the firebox

• Determine the size of the firebox (usually made large enough to comfortably load firewood).
• Use fireproof bricks or another refractory material for the inner walls of the firebox — this will increase the stove’s lifespan.
• Provide an opening or door (you can use a metal frame with removable doors) for adding fuel and controlling the burn.

5. Organizing air supply and grates

• For better combustion, the stove needs air. Usually, a grate is made at the bottom, with an air inlet below it.
• If there are no ready-made metal grates, they can be made from rebar or steel rods.

6. Installing the chimney

• Place a metal pipe or ready-made chimney at the top of the stove. Choose the pipe diameter according to the stove’s volume (usually 100–150 mm).
• Pay attention to the tightness of the connections to prevent smoke from leaking into the room.

7. Insulation and cladding

• Clad the outer surface with bricks. You can use the same fireproof bricks or an additional layer of refractory bricks to increase thermal mass.
• If you plan to cook, provide a steel plate on top or lay a “cooking” surface with fireproof tiles.

8. Final works

• Check with a level and visually ensure that all joints are tightly connected.
• Allow the mixture to dry completely (usually 2–3 days).
• Conduct a test burn with a small amount of fuel to check the draft, tightness, and safety of the construction.

Step-by-step instructions for a metal stove (brief)

1. Preparing the metal blank
   • If it is a barrel or an old gas cylinder, first thoroughly clean and degrease the surface. The cylinder must be purged and checked to ensure there are no gas residues.
2. Marking and cutting holes
   • Cut holes for the firebox, air inlet, and chimney.
   • If necessary, reinforce the edges with sheet metal.
3. Installing grates and doors
   • Make a grate from metal rods at the bottom of the stove (for the ash pan and air supply).
   • Attach the door (can be made from sheet metal with hinges).
4. Installing the chimney
   • Weld (or bolt) a metal pipe of the appropriate diameter for smoke evacuation.
5. Welding the structure
   • Check the welds for tightness.
6. Painting (optional)
   • Use heat-resistant paint to protect the metal from corrosion.
7. Trial run
   • Light a small amount of fuel to ensure that smoke goes into the chimney and that the wall temperature is safe for the surroundings.

Types of fuel for the stove

1. Firewood – the most common option. It is better to use dry hardwood (oak, beech, acacia).
2. Coal briquettes – provide more heat but are more expensive than firewood.
3. Pellets – require a special design or additional feeding device but burn quite evenly.
4. Coal – used less frequently due to higher burning temperatures and requirements for the stove’s fire resistance.

Safety and operation tips

• Proper ventilation. The room must have a supply of fresh air and exhaust to prevent carbon monoxide buildup.
• Distance to walls. Leave 20–30 cm of free space around the stove, especially if the walls are wooden or made of combustible materials.
• Floor protection. Place a metal sheet or fireproof tile under the stove to prevent sparks from damaging the flooring.
• Regular chimney inspection. Check and clean the chimney from soot. This will help avoid backdraft and smoke buildup.
• Never leave the stove unattended with an open flame, especially if there are children or pets in the house.

Advantages of a homemade stove

• Cost savings. The cost of materials and assembly is usually lower than factory solutions.
• Custom design. You can tailor the shape, size, and decor to your needs.
• Possibility of various modifications. Additional cooking surface, heat exchange system, or water circuit – it all depends on your imagination and skills.
• Reliability and durability. If you follow the correct technologies and use quality materials, the stove will serve for years.

Care and maintenance tips

• Cleaning the firebox. Regularly remove ash to prevent the grate from clogging and ensure good air flow.
• Inspecting seams (for metal stoves). Check for cracks or rust, and touch up with heat-resistant paint in a timely manner.
• Cleaning the chimney. At least twice a year (before and after the heating season).
• Checking hardware. Doors, hinges, handles, and air regulators should be in good working condition.
