Water heating at home is one of the major consumers of energy next to heating and cooling of the house. According to the US Department of Energy, water heating comprises 14% to 25% of the heating energy consumed in the home. There are number of aspects to consider while choosing and using a water heater.
There are various types of water-heating solutions such as electric and natural gas. Electric water heaters have the advantage of having a high energy factor but are considered to be a very expensive way to generate heat. The size of the water heater is another crucial aspect to consider. The water-heating solution needs to be able to provide enough water to satisfy the needs of the family even during the busiest hour. A typical storage water heater comes in a size of 20 to 80 gallons.
