An abreuvoir is a watering trough, fountain, or other installed basin: originally intended to provide humans and/or animals at a rural or urban watering place with fresh drinking water.

Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels that heat a batch of water do not produce a continual supply of heated water at a preset temperature. Rarely, hot water occurs naturally, usually from natural hot springs. The temperature varies with the ...
Lemna is a genus of free-floating aquatic plants referred to by the common name "duckweed".They are morphologically divergent members of the arum family Araceae.These rapidly growing plants have found uses as a model system for studies in community ecology, basic plant biology, ecotoxicology, and production of biopharmaceuticals, and as a source of animal feeds for agriculture and aquaculture.
Fired heaters (Image 3), also known as furnaces, may be used as a distillation column reboiler. A pump is required to circulate the column bottoms through the heat transfer tubes in the furnace's convection and radiant sections.

The splashing may increase the evaporation rate of the water and thus increase the salinity of the water body. Floating surface aerators work in a similar manner to fountains, but they do not offer the same aesthetic appearance. They extract water from the top 1–2 feet of the water body and utilize air-water contact to transfer oxygen.
