Welcome to the Rural Energy "G" Glossary Terms!

A type of steel coated with a layer of zinc to prevent corrosion and rusting, commonly used in heating system components such as ductwork, pipes, and fittings.

The component of a gas-fired heating system responsible for combusting fuel gas, typically found in furnaces, boilers, water heaters, and other appliances.

A component in gas-fired heating appliances that regulates the flow of fuel gas to the burner, controlling the heating output and temperature.

A heating system that uses natural gas or propane as a fuel source to generate heat for space heating, water heating, and other applications.

A device in gas-fired heating systems that maintains a consistent gas pressure at the burner, ensuring proper combustion and heat output.

A control device in gas-fired heating systems that regulates the flow of fuel gas to the burner, allowing for precise adjustment of heat output.

A pipe or duct used to exhaust combustion gases and byproducts from gas-fired heating appliances to the outdoors, ensuring safe and efficient operation.

temperature at which heating oil freezes solid and can no longer flow through fuel lines

Also called antifreeze, is an important compound that can be used to protect hydronic heating systems in cold climates. When added to water, glycol lowers the freezing temperature of the resulting mixture, ensuring that it remains liquid even during harsh winter weather.

You will see this rating if you are looking at an oil furnace. In addition to input and output, an oil furnace also has a rating of gallons per hour, the volume of oil a furnace is capable of burning in 60 minutes.

A type of heating system that relies on natural convection to distribute heated air throughout a building, typically found in older homes and buildings without forced-air systems.

A decorative or functional cover over an opening in a heating system, such as a return air grille or supply air grille, allowing airflow while providing protection.
