Context paragraphs:
Hot Water Music: Hot Water Music is a post-hardcore band from Gainesville, Florida.  The members of the band are Chuck Ragan, Chris Wollard, Jason Black, and George Rebelo.  HWM first formed in 1993.  In 1998, after releasing multiple EPs and three full-length albums, the band briefly disbanded, but soon reformed, announcing their continuation as Hot Water Music at the concert recorded for "Live at the Hardback".  They are represented by David "Beno" Benveniste's Velvet Hammer Music and Management Group.  In late 2005, Hot Water Music stated they were going on a hiatus following Chuck Ragan's departure.  On May 13, 2006 however, the hiatus became seemingly permanent and Hot Water Music officially disbanded.  The three remaining members then started a new project, The Draft, whose first album, "In a Million Pieces", was released on September 12, 2006.  Chuck Ragan also continued with a more low-key music career, releasing material through No Idea Records and Side One Dummy Records.  He is currently signed to the latter.  The band members have also participated in many side projects.  The four most popular of these are Blacktop Cadence, Cro(w)s, Unitas and Rumbleseat.

Hot water reset: Hot water reset is an energy-saving automatic control algorithm for hot water boilers that are typically fired with fuel oil or natural gas.  A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor temperature varies.  The supply hot water temperature is modulated up and down range in an inverse linear ratio to outside air temperature.  The typical range for conventional boilers is to vary the supply water temperature from 60 . .  82 ⁰C as the outside temperature varies from +18 . .  -18 ⁰C .

Hot water extraction: The Hot Water Extraction (HWE) method, is a method used in chemistry for extraction and for "steam cleaning".  The pressurized hot water extraction (PHWE) process uses a combination of high water pressure for agitation, and hot water to increase reaction rate.

Alkaline Trio / Hot Water Music: Alkaline Trio / Hot Water Music is a split EP by the Chicago-based punk rock band Alkaline Trio and the Gainesville, Florida-based punk rock band Hot Water Music, released January 22, 2002 through Jade Tree.  In addition to new material, the EP features each band performing cover versions of songs from the other band's catalog, with Alkaline Trio covering Hot Water Music's "Rooftops" (from "No Division") and Hot Water Music covering Alkaline Trio's "Radio" (from "Maybe I'll Catch Fire") and "Bleeder" (from "I Lied My Face Off").  It was Alkaline Trio's first release with drummer Derek Grant, who replaced previous drummer Mike Felumlee in 2001.

Hot water storage tank: A hot water storage tank (also called a hot water tank, thermal storage tank, hot water thermal storage unit, heat storage tank and hot water cylinder) is a water tank used for storing hot water for space heating or domestic use.

Instant hot water dispenser: An instant hot water dispenser or boiling water tap is an appliance that dispenses water at about 94 °C (near-boiling).  There are hot-only and hot and cool water models, and the water may be filtered as well as heated.  Instant hot water dispensers became popular in the 1970s.  Instant hot water dispensers are very similar to portable shower devices; the latter is fitted with a heating element and quickly heats up water, once a switch has been activated.

Storage water heater: A storage water heater is a domestic water heating appliance that uses a hot water storage tank to maximize heating capacity and provide instantaneous delivery of hot water.  Conventional storage water heaters use a variety of fuels, including natural gas, propane, fuel oil, and electricity.  Less conventional water heating technologies, such as heat pump water heaters and solar water heaters, can also be categorized as storage water heaters.  Conventional storage water heaters are the most common water heating type used in the United States.

Hot Water (song): "Hot Water" is a single released in 1984 by the British musical group Level 42.  It was released a couple of weeks before the album "True Colours".  The single reached #18 on the UK Singles Chart and was a top ten hit in the Netherlands and Norway.  The song was produced by Ken Scott

Ken Scott: Ken Scott (born 20 April 1947) is a British record producer/engineer widely known for being one of the five main engineers for The Beatles, as well as engineering Elton John, Pink Floyd, Procol Harum, Mahavishnu Orchestra, Duran Duran, The Jeff Beck Group and many more.  As a producer, Scott is noted for his work with David Bowie (on "Hunky Dory", "The Rise and Fall of Ziggy Stardust and the Spiders from Mars", "Aladdin Sane" and "Pinups"), Supertramp ("Crime of the Century" and "Crisis?  What Crisis? "), Devo, Kansas, The Tubes, Ronnie Montrose on Gamma 1, Level 42, among others.

Aquastat: An aquastat is a device used in hydronic heating systems for controlling water temperature.  To prevent the boiler from firing too often, aquastats have a high limit temperature and a low limit.  If the thermostat is calling for heat, the boiler will fire until the high limit is reached, then shut off (even if the thermostat is still calling for heat).  The boiler will re-fire if the boiler water temperature drops below a range around the high limit.  The high limit exists for the sake of efficiency and safety.  The boiler will also fire (regardless of thermostat state) when the boiler water temperature goes below a range around the low limit, ensuring that the boiler water temperature remains above a certain point.  The low limit is intended for tankless domestic hot water---it ensures that boiler water is always warm enough to heat the domestic hot water.  Many aquastats also have a differential ("diff") control which determines the size of the range around the "low" and/or "high" controls.
