Water heating is a process in which water is heated above its actual temperature using a particular source of energy- such as natural gas, LPG, oil, electricity, etc. Natural sources like solar energy and geothermal energy are also used to heat water. As such, hot water systems are differently designed to accommodate the needs of various consumers.
The benefit of hot water systems is that it provides a continuous supply of hot water, unlike kettles and geysers, which heat only a small amount of water at a time. Hence, heating systems are used when there is the need for large amounts of water, as in case of industries and factories. Following this, it is implied that hot water system prices vary with the attributes of the heating system- based on whether it is used for domestic or industrial use and the basic qualities of the product.
Hot water systems are of various types such as:
1. Gravity system- Here, boiler-heated water is used to heat potable water in a copper cylindrical vessel. This is mainly used in the UK to obtain hot water at a good flow.
2. On-demand water heaters- These are called by different names in various places such as tankless heaters (in North America) and multi-point heaters and geysers in other places. This hot water system provides a continuous supply of hot water without requiring any additional equipment.
3. Storage systems- Where the flow rate of hot water is needed to be higher, water is heated in such a pressure vessel which can withstand a good amount of hydrostatic pressure.
The most popular types of hot water systems are the tankless heaters and the solar water heaters. They are economical in that they use lesser energy. Hot water system prices range from $5 up to $1000, depending on the features of the product.
