If you have got a small family of two members who does not require much water on day to day basis, you should think twice before buying this type of unit spending huge amount of money. On the other hand, if you have got a quite large family with great demand for hot water every day, we believe that spending on this will give you a great return on investment.

By first-hour rating, we mean the gallons of water that your heater can supply you within the very first hour of operation.

For energy efficiency and operating cost, determining your fuel source is essential. Electric heaters are more expensive and less expensive. It comes with coils to heat the water.

Recovery rates: Knowing the recovery rate of your water heater is important. In electric water heaters, the recovery rate is comparatively slow when compared with gas water heaters. When you set a typical 50-gallon water heater run by electricity to 12 degrees, you may need approximately 1 hour and 47 minutes to heat water after entering the unit. However, if you at 70 degrees, it takes around 1 hour and 6 minutes to do the same.

On the other hand, if you use propane or natural gas, you will have a faster recovery rate. It will take about 53 minutes to heat the water at 40 degrees and 33 minutes at 70 degrees.

Usually, most of the Americans use propane or natural gas for their water heaters to save more energy and get a higher recovery rate.

Energy Factor: Energy factor or EF factor determines the energy efficiency a water heater comes with. You can measure energy efficiency after evaluating the amount of hot water against the fuel consumed. The more EF factor your water heater has, the better it is. If you go for a 50-gallon water heater, it should at least have an energy factor of .62 rate.

Energy-Star certification: If your 50-gallon water heater is certified by Energy Star, it means you have got a more efficient water heater. A water heater certified by Energy Star usually 15% more efficient than one without it.

Flow Rate: You should not ignore the flow rate of your water heater. It lets you know your access to hot water per hour. If you have got a water heater with a high flow rate, it means you have more possibility of getting enough hot water to meet your needs. That’s one of the most important things people look for when they opt to buy a water heater.
