A fireplace is usually a very simple combustion chamber, with or without front door, in which fuels are oxidised to obtain thermal energy, which is transferred into a space mainly by radiation. Ref EMEP/EEA air pollutant emission inventory guidebook 2016

A chimney is a brick, metal or concrete stack used to carry the exhaust gases from a fireplace into the free atmosphere and to generate draught.

A fireplace recess is a structural opening (sometimes called a builder’s opening) formed in a wall or in a chimney breast, from which a chimney leads and which has a hearth at its base.

Simple structural openings are suitable for closed appliances such as stoves, cookers or boilers, but gathers are necessary for accommodating open fires.
