Water heating is a heat transfer process that uses an energy source to heat water above its initial temperature. 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 ...
An electric steam boiler is a type of boiler where the steam is generated using electricity, rather than through the combustion of a fuel source. Such boilers are used to generate steam for process purposes in many locations, for example laundries, food processing factories and hospitals. Although they are more expensive to run than gas-fired ...

a boiler whose primary heating surface is composed of many small tubes, filled with water. Tubes of 3 inch diameter and above are termed "large-tube" boilers. Later water-tube designs used smaller "small-tubes" of 2 inches or less. Wet bottom furnace.
Thermal power station. A thermal power station, also known as a thermal power plant, is a type of power station in which the heat energy generated from various fuel sources (e.g., coal, natural gas, nuclear fuel, etc.) is converted to electrical energy. [ 1] The combustion or nuclear reaction of the fuel source in a boiler or reactor generates ...
A boiling water reactor ( BWR) is a type of light water nuclear reactor used for the generation of electrical power. It is the second most common type of electricity-generating nuclear reactor after the pressurized water reactor (PWR), which is also a type of light water nuclear reactor. The main difference between a BWR and PWR is that in a ...
There are 117 local district heating systems supplying towns as well as rural areas with hot water – reaching almost all of the population. The average price is around US$0.027 per kWh of hot water. [93] The Reykjavík Capital Area district heating system serves around 230,000 residents had an maximum thermal power output of 830 MW.
Hot water reset, also called outdoor reset ( ODR ), is an energy-saving automatic control algorithm for heating boilers that are typically fired with fuel oil or natural gas. A hot water reset control loop measures the outside air temperature; this information is used to estimate demand or heating load as the outdoor temperature varies.
