Heating systems are often made up of boilers burners and controls. A boiler is a closed container where liquid is heated. In most cases, the water inside does not actually boil, and the boilers are often called furnaces. The heat from inside exits the boiler and is used for heating homes, cooking and sanitation. Boilers burners and controls are available in different styles and sizes.
The use of boilers burners and controls is common in homes and businesses across the United States. The heat source for a boiler comes from a combustion of some type of fuel. Wood, coal, oil, or natural gas are some of the most common kids of fuel used.
Companies such as Cleaver Brooks and the aptly named Boilers Burners and Controls offer a variety of different boilers and other heating products. There are many different types of boilers. Some of the earliest were the pot boilers, also called Haycock boilers. They were old style kettle types, partially filled with liquid and heated over a fire. Used during the 18th century, Haycock boilers produced and stored a lot of very low pressure steam. They often burned coal, and sometimes wood. The level of efficiency was very low.
Modern day furnaces are much more efficient. Many have electronic ignition, so there is no need to have a pilot light burning all the time. New technologies in combustion allow more heat to be extracted from the same amount of fuel. Some have sealed combustion and use outside air to fuel the burner. This reduces drafts and improves safety.
