2. Heat transfer - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer

   An example of steady state conduction is the heat flow through walls of a warm house on a cold day—inside the house is maintained at a high temperature and, outside, the temperature stays low, so the transfer of heat per unit time stays near a constant rate determined by the insulation in the wall and the spatial distribution of temperature ...

3. Convection heater - Wikipedia

   en.wikipedia.org/wiki/Convection_heater

   Ancient heating systems, including hearths, furnaces, and stoves, operated primarily through convection.Fixed central hearths, which were first excavated and retrieved in Greece, date back to 2500 BC, whereas crude fireplaces were used as early as the 800s AD and in the 13th century, when castles in Europe were built with fireplaces with a crude form of chimney.

4. Direct vent fireplace - Wikipedia

   en.wikipedia.org/wiki/Direct_vent_fireplace

   To begin the operation of the fireplace unit, the user must turn on the gas supply and ignite the burners. Once this is done, the unit will operate completely autonomously until the gas supply to the burners is shut off. While in operation, convection will cause the hot air in the firebox to rise to the top of the firebox. As the amount of hot ...

5. Thermal conduction - Wikipedia

   en.wikipedia.org/wiki/Thermal_conduction

   Conduction is heat transfer through stationary matter by physical contact. (The matter is stationary on a macroscopic scale—we know there is thermal motion of the atoms and molecules at any temperature above absolute zero.) Heat transferred between the electric burner of a stove and the bottom of a pan is transferred by conduction.

8. Radiator (heating) - Wikipedia

   en.wikipedia.org/wiki/Radiator_(heating)

   A radiator is a device that transfers heat to a medium primarily through thermal radiation.In practice, the term radiator is often applied to any number of devices in which a fluid circulates through exposed pipes (often with fins or other means of increasing surface area), notwithstanding that such devices tend to transfer heat mainly by convection and might logically be called convectors.
