The answer to this question, if based solely on energy costs, can vary greatly depending upon where you live. In some regions, natural gas is cheaper than electricity whereas in other areas, the opposite is true. Generally, when it comes to heating water, gas heaters cost less because they are more energy efficient in heating water faster and using less energy in doing so. Left alone, the efficiency of gas heat may persuade you to purchase a gas heater rather than an electric one. However, there are a number of other reasons why you may consider purchasing an electric water heater.
A primary consideration for some is safety. The chances of an explosion from a gas leak and its resulting damage is far greater than any risks associated with electric wiring. Another enticing factor for those who are cost conscience is the ability to install a timer on an electric tank, limiting power consumption to off-peak times. Electric heaters do not require the venting of exhaust through PVC tubing. Gas heaters have space requirements to prevent the buildup of gases; whereas, an electric tank heater can be installed in small, unventilated spaces. The lifespan of an electric water heater is generally greater than a gas water heater. The purchase price of electric heaters is lower than gas heaters of the same size. Electric water heaters also do not have a pilot light to worry about.
It should be noted that new technology has also made improvements into the world of water heaters with options such as solar and tankless systems. Your local plumbing contractor will be well informed of all the pros and cons of various systems, so as to best assist you with the right purchase for your individual needs.
