  2. Hot water storage tank - Wikipedia

    en.wikipedia.org/wiki/Hot_water_storage_tank

    Hot water tanks may have a built-in gas or oil burner system, electric immersion heaters. Some types use an external heat exchanger such as a central heating system, or heated water from another energy source. The most typical, in the domestic context, is a fossil-fuel burner, electric immersion elements, or a district heating scheme. [2]

  3. Water heating - Wikipedia

    en.wikipedia.org/wiki/Water_heating

    Appliances that provide a continual supply of hot water are called water heaters, hot water heaters, hot water tanks, boilers, heat exchangers, geysers (Southern Africa and the Arab world), or calorifiers. These names depend on region, and whether they heat potable or non-potable water, are in domestic or industrial use, and their energy source.

  4. Thermometer - Wikipedia

    en.wikipedia.org/wiki/Thermometer

    Traditional thermometers were all non-registering thermometers. That is, the thermometer did not hold the temperature reading after it was moved to a place with a different temperature. Determining the temperature of a pot of hot liquid required the user to leave the thermometer in the hot liquid until after reading it.

  5. Absorption refrigerator - Wikipedia

    en.wikipedia.org/wiki/Absorption_refrigerator

    Common absorption refrigerators use a refrigerant with a very low boiling point (less than −18 °C (0 °F)) just like compressor refrigerators.Compression refrigerators typically use an HCFC or HFC, while absorption refrigerators typically use ammonia or water and need at least a second fluid able to absorb the coolant, the absorbent, respectively water (for ammonia) or brine (for water).

  6. Thermostat - Wikipedia

    en.wikipedia.org/wiki/Thermostat

    A thermostatic mixing valve uses a wax pellet to control the mixing of hot and cold water. A common application is to permit operation of an electric water heater at a temperature hot enough to kill Legionella bacteria (above 60 °C, 140 °F), while the output of the valve produces water that is cool enough to not immediately scald (49 °C, 120 ...

  7. Storage water heater - Wikipedia

    en.wikipedia.org/wiki/Storage_water_heater

    Solar heat is clean and renewable. This is the most modern system. Increasingly, solar powered water heaters are being used. Their solar thermal collectors are installed outside dwellings, typically on the roof or walls or nearby, and the potable hot water storage tank is typically a pre-existing or new conventional water heater, or a water heater specifically designed for solar thermal.

  8. Tankless water heating - Wikipedia

    en.wikipedia.org/wiki/Tankless_water_heating

    Power outage: In case of a power outage, tankless heaters cannot supply hot water, unlike tank based heaters which can supply the hot water stored in the tank. LED Light Strobe effect: Most residential demand water heaters act by modulating the heating elements to match the flow rate. This is required to prevent overheating in the heating chamber.

  9. Heat flux sensor - Wikipedia

    en.wikipedia.org/wiki/Heat_flux_sensor

    In this case the sensor is mounted on a water-cooled body. Such sensors are used in fire resistance testing to put the fire to which samples are exposed to the right intensity level. There are various examples of sensors that internally use heat flux sensors examples are laser power meters , pyranometers , etc.
