  2. Water heat recycling - Wikipedia

    en.wikipedia.org/wiki/Water_heat_recycling

    When recycling water from a bath (100–150 litres) or shower (50–80 litres) the waste water temperature is circa 20–25 °C. An in-house greywater recycling tank holds 150–175 litres allowing for the majority of waste water to be stored. Utilizing a built in copper heat exchange with circulation pump the residual heat is recovered and ...

  3. Waste heat recovery unit - Wikipedia

    en.wikipedia.org/wiki/Waste_heat_recovery_unit

    Focused on multi-unit residential, publicly shared buildings, industrial applications and district energy systems, their systems use the energy in waste water for domestic hot water production, building space heating and cooling. [8] Motorsport series Formula One introduced waste heat recovery units in 2014 under the name MGU-H.

  4. Biomass briquettes - Wikipedia

    en.wikipedia.org/wiki/Biomass_briquettes

    Briquettes provide higher calorific value per dollar than coal when used for firing industrial boilers. Along with higher calorific value, biomass briquettes on average saved 30–40% of boiler fuel cost. But other sources suggest that cofiring is more expensive due to the widespread availability of coal and its low cost. [9]

  5. Furnace (central heating) - Wikipedia

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

    In some areas electrical resistance heating is used, especially where the cost of electricity is low or the primary purpose is for air conditioning. Modern high-efficiency furnaces can be up to 98% efficient and operate without a chimney, with a typical gas furnace being about 80% efficient. [ 1 ]

  6. Waste-to-energy - Wikipedia

    en.wikipedia.org/wiki/Waste-to-energy

    In order to avoid losing the rest of the energy, it can be used for e.g. district heating (cogeneration). The total efficiencies of cogeneration incinerators are typically higher than 80% (based on the lower heating value of the waste). The method of incineration to convert municipal solid waste (MSW) is a relatively old method of WtE generation.

  7. Biomass heating system - Wikipedia

    en.wikipedia.org/wiki/Biomass_heating_system

    Biomass heating plant in Austria; the heat power is about 1000 kW Fully automatic 140 kW wood chip heating system in Austria. 35 years old. There are four main types of heating systems that use biomass to heat a boiler. The types of biomass heating are fully automated, semi-automated, pellet-fired, and combined heat and power.

  8. Central heating - Wikipedia

    en.wikipedia.org/wiki/Central_heating

    65–97% for gas-fired heating; 80–89% for oil-fired and; 45–60% for coal-fired heating. [26] Oil storage tanks, especially underground storage tanks, can also impact the environment. Even if a building's heating system was converted from oil long ago, oil may still be impacting the environment by contaminating soil and groundwater.

  9. Oil burner - Wikipedia

    en.wikipedia.org/wiki/Oil_burner

    An oil burner is a part attached to an oil furnace, water heater, or boiler. [1] It provides the ignition of heating oil/biodiesel fuel used to heat either air or water via a heat exchanger . The fuel is atomized into a fine spray usually by forcing it under pressure through a nozzle which gives the resulting flame a specific flow rate, angle ...
