Water Heater For Bathroom
Water heating is a thermodynamic process using an energy source to heat water above its initial temperature. Typical domestic uses of hot water are for cooking cleaning and bathing and space heating. In industry, both 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. 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 consumption rate becoming cooler as flow increases.

Appliances that provide a continual supply of hot water are called water heaters hot water tanks boilers heat exchangers geysers. These names depend on region and whether they heat potable or non-potable water are in domestic or industrial use and their energy source. In domestic installations, potable water heated for uses other than space heating is also called domestic hot water.

Most electric water heaters use electric resistance elements to heat the water in the storage tank using two electric resistance elements which are located at the bottom and top of the storage tank. Each element is controlled by an independent thermostat. In two-element tanks, the lower element provides recovery from standby losses and the upper element provides heating during periods of large hot water use. Some resistance water heaters contain only a lower element.

Electrical water heaters that store hot water can be a good match for an intelligent electrical power distribution system heating when the electrical grid load is low and turning off when the load is high. This could be implemented by allowing the power supplier to send load shedding requests or by the use of real-time energy pricing.

Heat pump water heaters use an air source heat pump to transfer thermal energy from the air around the unit into the storage tank. The electric resistance element is typically included to provide backup heating if the heat pump cannot provide sufficient heating capacity.
