Water Heaters

Hot water heaters are appliances used to heat water and to keep it at a more or less constant elevated temperature. Just as importantly, they are also used for the purposes of having a steady and continual supply of water. This is one big difference which sets hot water heaters apart from traditional heating vessels such as kettles, cauldrons, pots and coppers, with the latter being unable to provide constant stores of water.

Having a constant supply of hot water is of particular importance especially in temperate countries like the United States and in most European countries. Uses of hot water include cooking, bathing, cleaning, space heating, and the like. In the above mentioned countries, natural gas heaters which are piped along the course of cities and towns are extremely prevalent and widely used, because of their convenience, ease, and relative low costs. However, in contrast to natural gas heaters, hot water heaters which are sometimes known as domestic or storage water heaters, also have the added benefit of exploiting gas or electric energy at a more reduced rate and, of course, the ability to collect and store heated water for future use. Another thing with natural gas is that it contributes to global warming. And although domestic hot water heaters are more expensive than natural gas such that electric usage of these take up a major bulk of a electric bill, they are still preferable to natural gas for the reasons already cited.

There are different types of hot water heaters according to their use and other characteristics, such that they vary according to whether they are utilized for potable or non-potable water, or if they are used for domestic or industrial purposes, the energy source needed to run them, or where in the world they are located. Specifically, hot water heaters which are for household use and which heat potable water intended for functions aside from space heating are also called Domestic Hot Water (DHW). One of the newer inventions are tankless water heaters. These are electric and require no water storage system.

There are various sources of energy which are used to hot water heaters for heating water. The most common sources are fossil fuels in the form of natural gas, heating oil, propane, liquefied petroleum gas, solid fuels, etc. Subsequently, these energy fuels may be used up diametrically or they may be consumed with the use of electrical energy, which in turn may be obtained from any of the abovementioned fossil fuels or they may be derived from nuclear or renewable supplies. Other such forms of energy which may be used to hot water heaters include solar energy, geothermal energy, heat pumps, hot water heat recycling, and so on. Typically, geothermal power is usually used together with electricity, oil or gas.

In general, domestic hot water heaters employ energy to heat water up and store it using any one of two methods, specifically the thermosyphoning system or the circulation pump method. The former is simpler, and it entails that the storage tank be elevated compared to the coil which is an integral part of the pump. The circulation pump method, on the other hand, is the more flexible one in that there are fewer repercussions as regards the location of the tanks. Moreover, it is also more capable of affording a larger amount of heat transfer.
