If you are currently planning to buy the best water heater, then you are not alone. In September 2018, there were more than 6.4 million shipments of residential storage water heaters in the United States. That is just for one month and only for water heaters used in the home.
Most people, however, do not pay much attention to their water heaters until they have to replace it. That is quite surprising since the United States Energy Information Association estimates that water heating typically makes up 18 percent of your utility bills.
According to the U.S. Department of Energy, the typical American family spends more than $2,200 per year on their utilities. By not paying attention to your water heater, you are practically ignoring close to $400 a year. The best water heater can cut down on your heating costs by up to 25 percent.

The Considerations You Should Have When Buying the Best Water Heater
So, how do you choose the best water heater for your home? The United States Department of Energy has some tips.
Types of water heaters
Conventional storage water heaters can heat a tank full of water, while a tankless variety only warms water when you use it. Meanwhile, there are also heat pump water heaters that do not directly generate heat but moves heat from one source to the other.
Further, solar water heaters use the sun to make your water hotter. Then there are the indirect water heaters that use your home's heating system to give you hot water.
Things to consider
When you are trying to decide on the best water heater to buy, you should first think about the fuel type that the heater uses. There are areas where one or more types of fuel are not available, so check with your local utility company first before you buy.
You will also need to measure your demand. Do you need hot water only for bathing? Or do you use it for doing the laundry or washing the dishes? Getting the right-sized water heater will help you save on heating costs. Imagine boiling a tank full of water when you are going to use it only for taking a bath.
Further, buy a water heater that does not use up too much energy to give you hot water. You should also have a good idea of how much your preferred water heater will cost you for the whole year.
Warranty for the best water heater
It is always advisable to choose a water heater that gives you the most extended warranty on repairs and service.
One of fastest ways to cut down on your utility bills is to check the efficiency ratings.
You can first check if your selected heat has Energy Star certification. According to Energy Star, getting a certified water heater can help you save up to $3,500 over its lifetime. To see if the water heater you are considering is Energy Star certified, check this list of accredited heaters.
You can also look for the energy factor, which will tell you how much hot water is produced by burning a certain amount of fuel. The higher the EF is, the better.
Nice to have features
There are several features that you might want to see in the best water heater.
For instance, there are water heaters that have glass-lined tanks, which helps to minimize rusting. You can also buy those with digital displays that allow you to operate and monitor your water heaters, or those with anti-scale mechanisms, which reduce mineral build up.
How much can you expect to spend on the best water heater?
Pricing for water heaters varies widely. You can expect to pay anywhere from $100 to $1,800 for these heaters.
