subject: How to Select a Gas Water Heater [print this page] The majority of a household's energy bill comes from power used by gas water heaters. A significant expense like this should be well thought-out. There are different types of gas water heaters available. Determining the right one for your home could save you money.
Fuel Type: Natural gas heaters are most popular in the United States because gas is cheaper for heating water than electricity, propane, and solar energy. Also, most cities and towns have the gas conveniently piped throughout. Some homes are equipped for electric or propane and do not have a natural gas outlet available. If this is the case and you have gas stove it may be a good idea to extend the gas line to your water heater.
Size: A properly sized heater is necessary in order to meet a household's need for hot water efficiently. A heater that is too small will not provide enough hot water, and who wants to take a cold shower in the morning? If your heater is too big, then you will overpay to operate it. So, how do you determine what size gas water heater your home needs? Calculators are available online to determine your typical water-use and the water-use of your appliances and the amount of hot water the gas water heater can produce in an hour.
Energy Efficiency: This is based on the heater itself. Typically the most energy efficient models are the most expensive. Don't let the high price of the unit fool you into thinking you are wasting your money - in fact, an expensive gas water heater that is highly energy efficient will pay for itself and save you money on your monthly bills by cutting down on energy costs.
Costs: It is important to estimate a heater's annual operating costs so that you can make an informed decision about which one to purchase. Maintenance costs and installation add to the cost of purchasing a heater and should be considered as well. Taking into account the size of your home, and the energy efficiency and fuel type of the unit, should help you choose the heater that is right for you.
When selecting the best gas water heater for your home, it is important to consider these points. Overlooking any one of them could cost you money. Gas water heaters are a modern convenience, but choosing the wrong one could be a major inconvenience on your monthly energy bill.
