Parker's invention was further improved in 1935 by scientists who created forced convection wall heaters that use a coal furnace, electric fan, and ductwork throughout a home. Nowadays, homes utilize thermostats and forced air furnaces which can be attributed to Parker's design and invention of the central heating furnace.

A gas heater is a space heater used to heat a room or outdoor area by burning natural gas, liquefied petroleum gas, propane, or butane. Indoor household gas heaters can be broadly categorized in one of two ways: flued or non-flued, or vented and unvented .
David Lennox (April 15, 1855 – February 15, 1947) was an American inventor and businessman.

A condensing gas furnace includes a sealed combustion area, combustion draft inducer and a secondary heat exchanger. The primary gain in efficiency for a condensing gas furnace, as compared to a mid-efficiency forced-air or forced-draft furnace, is the capture of latent heat from the exhaust gases in the secondary heat exchanger.
