What is the best type of water heater for residential use?  It's an important question. The U.S. Department of Energy says that heating water is the second highest energy expense in the home, accounting for about 15 percent of an energy bill.  

There are four basic types of water heaters; 
▶︎ Natural gas
▶︎ Electric,
▶︎ Solar
▶︎ Tankless or point of use.  
 
The most common are gas and electric. 
 
Natural gas water heaters cost about 20 percent more than comparable electric models, but cost less to operate on a monthly basis.  In most communities, natural gas is a cheaper energy source to begin with. Natural gas water heaters also heat water more quickly than electric models, so they use less energy.  In a year of typical use, the higher initial cost of a natural gas water heater will be made up for in about a year of lower energy costs.

Installation costs are also higher for natural gas water heaters.  It's possible for a homeowner who has done some research to install an electric water heater on their own, but a licensed plumber is the only one who should install a natural gas water heater.  Improperly installed valves or poor venting can lead to a natural gas buildup and possible fatal consequences with Carbon Monoxide buildup or even an explosion.  

A solar water heating system can cost up to $10,000 to install and still requires some electricity to power a backup system in case of extended cloudy days.  The systems can last about 30 years and the cost can be made up slowly over the life of the system, but it requires that a homeowner stay in the home for decades before realizing any savings.

A tankless or point of use system requires a small electric water heater placed at every point of use.  It heats water quickly, but sometimes has capacity issues during periods of long use.

The term tankless is a bit deceiving. The water is heated inside a "small" tank and there is no large storage tank.
 
Two other issues that also need to be considered are capacity and what's called the "first hour rating" or how many gallons of hot water a water heater can generate in one hour.
  Smaller water heaters are cheaper than large ones, but if you don't have enough capacity, you will wish you had purchased a bigger one. 
A family of three or four can get by on a 60 gallon tank, but any more people than that should be using an 80 gallon tank.

The first hour rating is also important.  The capacity can be large enough, but if you have showers, laundry and other uses competing at the same time, someone is going to get cold water unless your water heater can keep up.
