Traditionally, hot water tanks are large cylinders located in the basement. They are capable of containing between 20 to 100 gallons of heated water. Depending upon size, age and efficiency, it can easily provide sufficient water for most homes. The source of heat for these appliances varies. Gas is common. However, many homes have an electric hot water heater.
Basic Types of Hot Water Heaters
No matter what their source of energy, hot water heaters are available in different models. They come in diverse styles to suit their application and environment. Among the three basic types of heaters are
- 1. Conventional: These feature tanks in which water sits, heated and always ready to use. They tend to be the largest in size, requiring basements and other larger spaces in which to function optimally
- 2. Tankless: Also referred to as “on demand” water heaters, they are smaller and heat the water only as requested. They can be a stand-alone unit or work in conjunction with a traditional system
- 3. Tankless coil and indirect: These come without a tank. Their source of heat is the existing heating system. In fact, they act as both the residential heating system and the hot water supplier. Such types feature longevity and a seemingly endless supply of hot water.
Electric Hot Water Heaters
Whatever the format, the energy source remains significant. It can affect its reliability and efficiency. An electric hot water heater rates high in several categories in comparison to other types, including natural gas. Electric hot water heaters are:
- Highly efficient
- Are very energy efficient – almost all the electricity used to heat water goes directly towards this purpose
- Costs less to install
- Is easier to install
The Electric Hot Water Heater
Electricity is one source for heating hot water. An electric hot water heater offers several advantages over its counterparts. Its energy efficiency and ease of installation reduce the cost, making it an attractive option to natural gas.
