Welcome to the Rural Energy "F" Glossary Terms!

A temperature scale with the freezing point of water 32F and the boiling point 212F at sea level.

Fans circulate warm air through the ducts and out the vents.

A control device in furnaces and heating systems that turns the blower fan on or off based on temperature settings, ensuring proper heat distribution.

In most stoves the inside walls of the firebox are lined with loose-fitting panels usually called firebricks. These serve 2 purposes - firstly they help to keep heat in the firebox leading to higher efficiencies and cleaner combustion, and secondly to protect the outer walls of the stove from the direct heat of the flames. Traditionally the firebricks were made from Refractory Clay

The chamber within a heating appliance where fuel is burned to generate heat, such as in wood stoves, fireplaces, or boilers.

The chamber inside a stove where the actual combustion (burning of fuel) takes place.

A device which indicates if the stove fuel is burning, or if ignition has been lost. The indication may be transmitted to a signal or to a control system.

Sheet metal used to make a water-tight seal between the chimney and the roof.

Flue refers to a duct, pipe, or chimney through which combustion gases or exhaust from a heating appliance are vented outdoors. It serves to safely convey combustion byproducts away from the building, preventing indoor air pollution and maintaining proper ventilation. The flue is a critical component of heating systems, ensuring efficient and safe operation by directing exhaust gases away from occupied spaces.

the diameter of the flue, Larger fires/stoves need larger flues as they simply have a greater volume of flue gases that need to exit the fire.

The product of combustion from the appliance through the breeching and/or chimney into the atmosphere.

A heating system that distributes heated air throughout a building using a fan or blower, typically powered by a furnace or heat pump.

a stove with legs or a base on which it stands. A free-standing stove can fit inside a fireplace opening with a small gap around it or can stand in the open e.g. in a room with no fireplace

A brand name for a group of refrigerants used in heating, ventilation, air conditioning, and refrigeration systems to transfer heat between indoor and outdoor environments.

A feature in heating systems that prevents damage to pipes, equipment, or crops by maintaining temperatures above freezing during cold weather conditions.

A fuel oil similar to kerosene

A distillate home heating oil

The measure of how effectively a heating system converts fuel into usable heat energy, often expressed as a percentage or energy rating.

Any oil used in an engine or furnace

A heating system that generates warmth by burning fuel or using electricity to produce heat, typically distributing it through ductwork to various rooms or zones in a building.
