Boiler is the correct nomenclature used in the home heating trade...
same as hot water heater is used rather than the full terminoligy;
domestic hot water heater... most building trade workers couldn't
spell domestic (they can't use three syllable words). There are
several catagories of boilers; cast iron, sheet metal, wet base,
etc... "boiler" is the correct building trades jargon... same as most
folks use that four letter word in lieu of sexual intercourse... I'll
bet there's not a person here who has ever said to their mate let's
have sexual intercourse/coitus... sf says "C'mon, penetrate me!",
hubby replies "Which orifice?" Probably the one to shut her up! LOL
