  2. Heating system - Wikipedia

    en.wikipedia.org/wiki/Heating_system

    Central heating systems: These systems produce heat in one central location and distribute it throughout the building. This category includes furnaces, boilers, and heat pumps. [1] [2] Distributed heating systems: These systems generate heat in the space they are to heat, without extensive duct systems. Examples include electric space heaters ...

  3. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    Institutional heating systems (office buildings or schools, for example) can use low-grade, inexpensive bunker fuel to run their heating plants, but capital cost is high compared to more easily managed liquid fuels. Natural gas is a widespread heating fuel in North America and northern Europe. Gas burners are automatically controlled and ...

  4. Heating degree day - Wikipedia

    en.wikipedia.org/wiki/Heating_degree_day

    Heating degree day (HDD) is a measurement designed to quantify the demand for energy needed to heat a building. HDD is derived from measurements of outside air temperature . The estimated average heating energy requirements for a given building at a specific location are considered to be directly proportional to the number of HDD at that location.

    But those who heat with oil will catch somewhat of a break after a pricey heating season last year, with costs expected to rise only 6.1% to $1,963 this winter. A weak oil market has led to a drop ...

  6. Register (air and heating) - Wikipedia

    en.wikipedia.org/wiki/Register_(air_and_heating)

    Ideally, a room will have both heating and cooling registers. In practice, cost considerations usually require that heating and cooling be provided by the same register. In such cases, heating most often takes precedence over cooling, and registers are usually found close to the floor. [7] For heating purposes, a floor register is preferred.

  9. Air source heat pump - Wikipedia

    en.wikipedia.org/wiki/Air_source_heat_pump

    Although higher cost heat pumps can be more efficient a 2024 study concluded that for the UK "from an energy system perspective, it is overall cost-optimal to design heat pumps with nominal COP in the range of 2.8–3.2, which typically has a specific cost lower than 650 £/kWth, and simultaneously to invest in increased capacities of renewable ...
