2. Heat press - Wikipedia

   en.wikipedia.org/wiki/Heat_press

   A heat press is a machine engineered to imprint a design or graphic on a substrate, such as a t-shirt, with the application of heat and pressure for a preset period of time. While heat presses are often used to apply designs to fabrics , specially designed presses can also be used to imprint designs on mugs, plates, jigsaw puzzles, caps, and ...

3. Concentrated solar still - Wikipedia

   en.wikipedia.org/wiki/Concentrated_solar_still

   A typically 25% efficiency standard solar still (not allowing for any recovery of rejected latent heat), as the latent heat of vaporization of water is 2.26 MJ per kilogram, [3] should evaporate 2.4 kg (or liters) of water per m 2 per day in a region with an average daily solar irradiation of 21.6 MJ/m 2 (250 watts/m 2), or 873 liters per year ...

4. Central heating - Wikipedia

   en.wikipedia.org/wiki/Central_heating

   A central heating system has a furnace that converts fuel or electricity to heat. The heat is circulated through the building either by fans forcing heated air through ducts, circulation of low-pressure steam to radiators in each heated room, or pumps that circulate hot water through room radiators.

5. Heat transfer - Wikipedia

   en.wikipedia.org/wiki/Heat_transfer

   The process of heat transfer from one place to another place without the movement of particles is called conduction, such as when placing a hand on a cold glass of water—heat is conducted from the warm skin to the cold glass, but if the hand is held a few inches from the glass, little conduction would occur since air is a poor conductor of heat.

6. Convection (heat transfer) - Wikipedia

   en.wikipedia.org/wiki/Convection_(Heat_transfer)

   As a consequence, the fluid is displaced while the cooler fluid gets denser and the fluid sinks. Thus, the hotter volume transfers heat towards the cooler volume of that fluid. [2] Familiar examples are the upward flow of air due to a fire or hot object and the circulation of water in a pot that is heated from below.

7. Ground source heat pump - Wikipedia

   en.wikipedia.org/wiki/Ground_source_heat_pump

   A heat pump in combination with heat and cold storage. A ground source heat pump (also geothermal heat pump) is a heating/cooling system for buildings that use a type of heat pump to transfer heat to or from the ground, taking advantage of the relative constancy of temperatures of the earth through the seasons.

8. Moving heat source model for thin plates - Wikipedia

   en.wikipedia.org/wiki/Moving_heat_source_model...

   In the 1930s metallurgists Albert Portevin and D. Seferian attempted to experimentally determine heat transfer characteristics in welding. [1] They correlated the effects of several factors—material properties, welding process, and part dimensions—on temperature distribution, by performing oxyacetylene (gas) and covered electrode (arc) welds on plates and bars of various profiles, and ...

9. Furnace (central heating) - Wikipedia

   en.wikipedia.org/wiki/Furnace_(central_heating)

   By comparison, most modern "warm air" furnaces typically use a fan to circulate air to the rooms of house and pull cooler air back to the furnace for reheating; this is called forced-air heat. Because the fan easily overcomes the resistance of the ductwork, the arrangement of ducts can be far more flexible than the octopus of old. In American ...
