Typical domestic uses of hot water include cooking, cleaning, bathing, and space heating. In industry, hot water and water heated to steam have many uses.. Domestically, water is traditionally heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers.

Are Tankless Water Heaters Really Gree

Yes, says Michael Chandler, a builder in Chapel Hill, NC, on-demand hot water heaters are “more of a luxury than an energy conserving solution,” but keep in mind that most gas tank-style hot water hears are only about 60% efficient.

Domestic water-supply - example - johnhearfie

In this section I show how to calculate the flow-rate in a real domestic water-supply system by using a couple of design tools that link flow-rate to the available head - the pressure that makes the water move. The worked example starts here .If all you need is the graph that links flow rate to the rate-of-pressure-drop for standard pipe sizes, it's here .
