There are several types of water heaters. These include storage water heaters, demand, or instantaneous water heaters, heat pump water heaters, indirect water heaters, and solar water heaters.

Among these types, the storage water heaters are the most common type in the United States. A storage water heater ranges in size from 20 to 80 gallons and is fueled by natural gas, electricity, propane, or oil. Basically, they work by heating up water in an insulated tank. Although most people use this type of water heater, the demand for water heaters continues to grow in the United States.

The reason for this growing demand is the many conveniences they offer to consumers. For example, they have eliminated the need for a storage tank by heating water directly, as is the case with a natural gas water heater. But this type of water heater does not make sense in all homes. The three remaining types, although they have their own advantages, are not as popular as the first two types of water heaters.

With the many types of water heaters available, it does pay to choose one that can best satisfy your hot water needs. See to it that your water heater uses as little energy as possible. And whether you are replacing a worn-out existing water heater or looking for a brand new model for your new house or apartment, you must do your research thoroughly to find the water heater that offers the highest level of energy efficiency. Take your time in searching because this will be the key for a successful buy rather than one bought on impulse.
