What You Need To Know About BTU’s Before Buying a Fireplace or Fire Pit?

Choosing a fire pit, fireplace or even a grill for your home may be a challenging task considering the variety available in the market. With so many sizes, shapes, models, and price ranges to choose from, finding the right one for your needs can be really tough. To make matters worse there is a world of technical terms and abbreviations to fathom.

The moment you step inside a store or visit an online store you will be greeted with a world of terms LP, NG, and BTUs. If science is not your thing, then these terms will sound even more frightening to you. However, in order to know your fire feature well before you make a purchase, you must properly understand the technical details behind it.

BTU is one important things that you must consider when you purchase a fireplace, fire pit, or even a grill. BTU stands for British thermal Unit It is a unit that measures the heat generated by your burner. In technical terms, one British thermal unit will increase the temperature of a pound of water by 1 degree Fahrenheit. When it comes to a fire pit or fireplace, higher BTU’s mean the more heat and more flame the fireplace or appliance with generate. In a fire pit or any other outdoor appliance, BTU output generally ranges from 30,000-100,000. So, the higher the BTU of the fire feature, the more warmth it will provide.

Apart from BTU there are several other factors that affect the flame height and appearance on a burner. Some of these things are:

  • The amount of air mixed with gas before it is burned affects the flame height and overall color. The more the air, bluer and shorter will be the flame. However, it will be cleaner and will have a higher temperature. To add more air, you will need to open the air regulator more at the orifice. To add less air, you can close the air regulator. With lesser air, you get a taller and a brighter yellow flame. However, if you close the air valve too much you will get a dirty flame. Even though it will still cleaner than wood fire, but it will generate a high CO2 level.
  • Larger orifice in the burner means more BTUs
  • Higher gas pressure also means more BTUs
  • Natural gas has less BTUs/cubic feet compared to liquid propane

Liquid propane and natural gas are sold by the BTU. This means, the more BTUs the burner uses per hour, the higher it will cost you to run the fireplace or fire pit. So, even though you may want a higher BTU measure for your fireplace or fire pit, you will also need to consider other factors while making a choice.
