Bathtub - definition
A bathtub, bath or tub (informal) is a large container for holding water in which a person may bathe. Most modern bathtubs are made of acrylic or fiberglass, but alternatives are available in enamel on steel or cast iron; occasionally, waterproof finished wood. A bathtub is usually placed in a bathroom either as a stand-alone fixture or in conjunction with a shower.
Modern bathtubs have overflow and waste drains and may have taps mounted on them. They are usually built-in, but may be free-standing or sometimes sunken. Until recently, most bathtubs were roughly rectangular in shape but with the advent of acrylic thermoformed baths, more shapes are becoming available. Bathtubs are commonly white in colour although many other colours can be found. The process for enamelling cast iron bathtubs was invented by the Scottish-born American David Dunbar Buick.
Two main styles of bathtub are common:
Western style bathtubs in which the bather lies down. These baths are typically shallow and long.
Eastern style bathtubs in which the bather sits up. These are known as ofuro in Japan and are typically short and deep.

Boiler - what is it?
A boiler is a closed vessel in which water or other fluid is heated. The fluid does not necessarily boil. (In North America the term "furnace" is normally used if the purpose is not actually to boil the fluid.) The heated or vaporized fluid exits the boiler for use in various processes or heating applications,12 including water heating, central heating, boiler-based power generation, cooking, and sanitation.
