Hot Water System Repairs And Installation
There are many different names for the appliances that deliver a continuous stream of hot water to our homes. In some regions they are called hot water heaters or hot water tanks. In other locales, they are referred to as heat exchangers and boilers and even calorifiers and geysers. No matter what they are called, these hot water systems make our homes very livable.
Water heaters are used in both industrial and domestic settings. Some are used to heat drinking water while others are used to heat non-potable water. In most cases, the heated water is used for cooking, bathing, and washing clothes or dishes. However, in some cases, hot water systems form the basis for a home heating system.
Heating water requires a great deal of energy and that energy comes from a wide variety of sources. Electricity and natural gas are the most commonly used ways to supply the needed energy to raise the temperature of water, but there are other alternative energy sources that are increasingly being used. These include geothermal heating, hot water heat recycling, heat pumps, and solar energy.
In southern Asia as well as on the North American continent, tank water heaters are the most common type of water heating system in use. Hot water is kept ready for use in a cylindrical tank. These tanks can hold anywhere from 75 up to 400 gallons, depending upon their construction. In both Europe and the United States, natural gas is frequently used to heat them due to the extensive piping infrastructure and the low cost per unit.
There are advantages and disadvantages when it comes to water heaters with tanks. Because the water is stored at a high temperature, it tends to use less energy each hour. However, when the heated water sits in the tank for a long period of time, it gradually cools down and energy must be expended to reheat it. Another disadvantage to this type of system is that once all the hot water has been used, it will take time to reheat the cool water that replaced it. Water heaters with larger tanks tend to be more energy efficient than the ones with small tanks.
In regions where the average daily temperature is lower, point-of-use water heaters are becoming more popular. These hot water systems use electricity to heat water when it is needed. They provide limited amounts of hot water at any given time and are generally attached directly to a sink. In some cases, they are used in conjunction with a hot water heating system located far away. These systems deliver heated water until the water in the remote location arrives.
Hot water systems come in many different types. As the world moves towards greater efficiency, expect to see more changes in construction. They are used in both domestic settings as well as within industrial environment. Because of this, they have a wide range of capacities and can draw on many different energy sources for power.
