There are many options available to homeowners looking to purchase new water heater systems. Potential efficiency should be evaluated, keeping the cost of initial installation in mind. Life expectancy and functionality of a new unit should also be considered. Many people also look for environmentally friendly models.

Electric units trump natural gas units in terms of energy efficiency. Electric tanks are superior because they allocate, direct, and utilize all incoming electricity to heat the water. This design is completely energy efficient. The average efficiency rating of natural gas units is roughly seventy percent, as a result of the chemical products they incorporate.

Installation and operation costs are further essential considerations. Electric and gas prices fluctuate over the course of the year, evaluation of average annual costs are the only way to calculate a rough operation estimate. But these figures aren't exactly concrete enough to determine future anticipated operational costs garnished throughout the lifetime of the unit.

Installation generally costs less for electric units. Natural gas units require more labor to install, and a qualified expert must perform these types of installations in almost every instance. Sometimes electric hot water systems may require the involvement of a licensed electrician, but the likelihood of this is far less than the need for a licensed gas fitter in the event of a natural gas unit however.

Gas fueled units are continuously subjected to corrosive elements that eat away at the inner tank chamber. This is why electric units have more longevity than their natural gas counterparts. Local water quality also affects the lifespan of your water heater as some locations have softer water supply than others. You can clearly see the difference when comparing the two extremes, municipal water sources and well water sources.

Environmentalists will generally prefer the heat water with electricity. Primarily because with electricity there are no emissions and therefore do not contribute to the already escalating greenhouse gasses that pollute our atmosphere. Natural gas is one of the best fossil fuels for emission output, but it still releases some carbon into the air.

There are many different aspects to consider before you purchase a new heater, or make an upgrade. Remember to research installation and operation costs, along with the efficiency rating and life expectancy of your new water heater.

Another option many people have found attractive is an on demand water heating system. In this system there is no storage tank and water is heated based on need which helps to reduce the overall monthly utility bill.
