What You'll Learn

Calor Gas is liquefied petroleum gas (LPG)
LPG has two primary forms: propane and butane. Propane, which comes from natural gas processing and oil refining, has a boiling point of -42°C, making it ideal for outdoor use such as BBQs and patio heaters. Butane, on the other hand, comes from refining petrol and has a higher boiling point of -2°C, making it more suitable for indoor use in portable heaters and cookers. Both types of LPG are hydrocarbons with similar properties, and they are chemically similar to each other.
Calor Gas was established in 1935 and is one of the largest suppliers of LPG in the UK, servicing approximately 4 million homes and businesses. The company was formed when the entrepreneur Arthur Gill spotted an opportunity to introduce liquefied petroleum gas to the UK market, and the name "Calor Gas" was coined. Initially, Calor Gas was used primarily for cooking and heating appliances, but over time, the company expanded its offerings to include a wider range of products for home, business, and automotive fuels.
As a fossil fuel, LPG is formed from the decomposition of organic matter, such as plankton and plants, over millions of years. Fossil fuels, including LPG, have been important to human development due to their ability to be readily burned in the open atmosphere to produce heat and power machinery. However, it is essential to consider the environmental impact of burning fossil fuels, as they contribute significantly to greenhouse gas emissions and air pollution.
