Water heating is a thermodynamic procedure using a power source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking, cleaning, bathing, and space heating. In industry, both hot water and water heated to condensation have many uses. Domestically, water is usually heated in vessels known as water heaters, kettles, cauldrons, pots, or coppers. These metal vessels heat a batch of water, but do not produce a continual supply of heated water at a preset temperature. The temperature will vary based on the consumption rate of hot water; the water becomes cooler as flow is increased. Appliances for providing a more-or-less stable supply of hot water are variously known as water heaters, hot water heaters, hot water tanks, boilers, heat exchangers, calorifiers, or geysers depending on whether they are heating filtered or non-potable water, in domestic or industrial use, their energy source, and in which part of the world they are found. In domestic installations, potable water heated for uses other than space heating is sometimes known as domestic hot water (DHW).

Long-term energy savings : Although a water heater might cost more initially it may result in both energy and cost savings in the long term. As water is heated only when it is needed, there is no storage of hot water. With a tank, water is kept warm all day even if it never gets used and heat loss through the tank walls will result in a continual energy drain. Even in homes or buildings with a high demand for hot water, a water heater may provide some level of savings. In a typical home these savings are quite substantial. If instant hot water at the taps at limited hours is a priority, using an aquastat and timer in order to decrease the added heat loss from the recirculation system can accommodate a recirculation system similar to those in the tank-type systems. It has to be said though that if the storage tank is highly insulated-a few tanks are available with excellent levels such as 100 mm or more polyurethane foam-the savings become minimal. For one consumer-grade electric storage water heater, the surface temperature was less than 1 C higher than the air temperature.
