Permanent Fire Pits are are fixed structures, either built in place using long lasting materials such as bricks and mortar, rocks and stone or are so heavy that moving them is not an option. You have the advantage of been able to design them to blend in with your existing patio or yard, even matching the materials already in place. The only limitations for this is your own imagination. If you don’t have the budget or building skills for elaborate projects then the easy option is to buy a pre-designed permanent fire pit kit that you can easily put together yourself. If even that is more than you fancy doing then buy a ready made fire pit.
By placing the fire pit away from the flow of traffic and raising the fire pit from the ground you will make it hard for anyone to accidentally walk or fall in. Choose a location for the fire pit that will reduce as much as possible the effect of smoke on neighbouring properties, or even you own or that matter. If this an issue then go with a gas burning fire pit as they do not emit smoke. If children are a factor, incorporate a barrier such as a low wall surrounding the pit that will ensure they are kept a safe distance from the flames. Some portable fire pits are designed with a protective glass or Pyrex shield. This also helps limit the wind’s affect on the flames.
For wood burning fire pits always use a safety screen. They come in various shapes and sizes and will help contain sparks and flying embers. Some models are sold with them, however if you are building fire pit make sure you incorporate a screen into the design. Materials used in fire pits should be carefully considered. Porous stone, non treated river rocks and even cinder blocks should not be used inside a fire pit. When placed near intense heat, they can explode. Standard building bricks will eventually crack and need replacing over time. In order to prevent this fire pits should be lined with fire rated materials such as firebricks or thick steel rings. Use fire rated mortar. Adhesives are not advised as when heated they can give off unhealthy fumes.
In describing the basic essentials for fire, many speak of the "fire tetrahedron." In other words, besides the original "fire triangle" of fuel, heat and oxygen, they add the fourth essential of chemical reaction. Fire pits use all four! It is necessary for us to understand the part each of these plays in producing fire so that we can put it to use in either lighting our fire pit and preventing or extinguishing unwanted fires. For example, to put out a grease fire on the stove, turn off the stove (removing the heat) and cover with a lid (removing the oxygen that feeds the fire). This will also benefit those contemplating buying a fire pit, helping them to decide which fire pits are best for them. So to get a better idea of what causes fire in your fire pit, let’s take a look at these four basic elements.
