  2. Underfloor heating - Wikipedia

    en.wikipedia.org/wiki/Underfloor_heating

    Under floor radiant systems are evaluated for sustainability through the principles of efficiency, entropy, exergy [32] and efficacy. When combined with high-performance buildings, underfloor systems operate with low temperatures in heating and high temperatures in cooling [33] in the ranges found typically in geothermal [34] and solar thermal ...

  3. Radiant heating and cooling - Wikipedia

    en.wikipedia.org/wiki/Radiant_heating_and_cooling

    Radiant heating and cooling. Radiant heating and cooling is a category of HVAC technologies that exchange heat by both convection and radiation with the environments they are designed to heat or cool. There are many subcategories of radiant heating and cooling, including: "radiant ceiling panels", [1] "embedded surface systems", [1] "thermally ...

  4. Underfloor air distribution - Wikipedia

    en.wikipedia.org/wiki/Underfloor_air_distribution

    Underfloor air distribution. Coordinates: 36.7377°N 119.7838°W. Diagram of air movement in an underfloor air distribution system. Underfloor air distribution (UFAD) is an air distribution strategy for providing ventilation and space conditioning in buildings as part of the design of a HVAC system. UFAD systems use an underfloor supply plenum ...

  5. Ground source heat pump - Wikipedia

    en.wikipedia.org/wiki/Ground_source_heat_pump

    A heat pump is the central unit for the building's heating and cooling. It usually comes in two main variants: Liquid-to-water heat pumps (also called water-to-water) are hydronic systems that carry heating or cooling through the building through pipes to conventional radiators, underfloor heating, baseboard radiators and hot water tanks. These ...

  6. Air source heat pump - Wikipedia

    en.wikipedia.org/wiki/Air_source_heat_pump

    An air-to-water system only pumps heat inwards, and can provide space heating and hot water. [8] For simplicity, the description below focuses on use for interior heating. The technology is similar to a refrigerator or freezer or air conditioning unit: the different effect is due to the location of the different system components.

  7. Hypocaust - Wikipedia

    en.wikipedia.org/wiki/Hypocaust

    Hypocaust. A hypocaust (Latin: hypocaustum) is a system of central heating in a building that produces and circulates hot air below the floor of a room, and may also warm the walls with a series of pipes through which the hot air passes. This air can warm the upper floors as well. [1] The word derives from the Ancient Greek hypo meaning "under ...

  8. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Central heating. A central heating system provides warmth to a number of spaces within a building from one main source of heat. It is a component of heating, ventilation, and air conditioning (short: HVAC) systems, which can both cool and warm interior spaces. A central heating system has a furnace that converts fuel or electricity to heat.

  9. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    A heating system is a mechanism for maintaining temperatures at an acceptable level; by using thermal energy within a home, office, or other dwelling. Typically, these systems are a crucial part of an HVAC (Heating, Ventilation, and Air Conditioning) system. A heating system can be categorized into central heating system or distributed systems ...
