In a civilized society, at least people have enough potable water to drink and enough safe food to eat. In the USA, we use much more water per person than other countries. We don’t only use water to drink or cook, but also heat water to take a bathe. Therefore, just remember don’t think very countries have enough water to heat for a bathe.
If one family has 4 persons, generally, the energy that is used to heat enough water for every family member can account for over 30% of total home’s energy budget. The portion is large. If we use an improper type of energy to heat water, the number will increase. Therefore, both the mode of heating and the energy we use to heat water are very important to our energy bill. And we can do more to save our money.
Basically, there are some sources of energy we can choose, such as oil, gas, electric and solar. Choosing which type depends on how much hot water you family needs every day and where you live. How to store the hot water is also based on these 2 questions.
You can choose a traditional hot water tank which is able to keep the hot water at a constant temperature and you can use the hot water when you need it, without any waiting. Generally, the tank of a traditional heater can hold 40 to 80 gallons of hot water. Or you also can choose a newer tankless water heater that a heating element heat water for you at the same time as you need it. Generally, a tankless heater is more efficient than a traditional one, because it only heat water when you need it. Because of no tank design, tankless heater don’t consume any energy when you don’t use it. To maintain a constant temperature, when the temperature drops in the tank, the water will be heated again to the temperature it was. This process will consume much energy than you think.
Another great option is that you can choose a solar heater system additionally, if you live in a sunny area. Insulated tubing are installed on the roof of your house to absorb solar energy to heat water. Once the water in the Insulated tubing reaches a setting temperature, a tank is used to store the hot water which are ready for you. During the day, solar panels can generate enough electricity to run the pumps, circulate the water and heat the water. If conditions are good, choosing a solar heater is a good choice both for you money and the environment.
Before making a buying decision, learning more about them is helpful. The one you choose will live with you for the next 20 years or more, so consider carefully.
Learning all you can about hot water heaters, and discovering all the choices you have is a great way to help make this decision. Please consider, whatever you purchase, you will probably live with it for the next 30 years, or more.
One market, there are several types of hot water heaters and we’ve chosen the best water heaters for you to choose from.
Electric Water Heater
Electric Water Heaters use electrical energy to heat and retain water in a cylinder that is insulated. They can offer you the whole stored quantity immediately deliver hot water at mains pressure. Once the hot water in the cylinder is ran out, it will reheat the cold water coming in. This process needs to take some time but it is very quick. They are widely installed outdoors or indoors, especially there is no natural gas in some area and you can make it run on lower cost off-peak electricity.

Tankless Water Heater
This kind of water heaters doesn’t have a tank to hold hot water. Mostly they are powered by natural gas. They use high-powered burners to heat cold water quickly. Generally, they are 22% more energy efficient compared with other natural gas storage-tank heaters.
Natural Gas Water Heater
They are powered by natural gas not solar or electricity. They can offer you hot water immediately because of their more efficient heater exchanges. They come in 2 types: tankless or storage-tank. It is highly recommended to buy a tankless model.
Solar Water Heater
Solar water heaters don’t use any fossil energy but the solar energy, making it much more energy efficient and cleaner to use. However, if the area you live doesn’t have a sunny and warm (or hot) weather in a whole year, they may not your best choice. Therefore, make sure the conditions are right. Nowadays, some models also can be powered by natural gas, if the weather is bad.
Point-of-Use Water Heater
This type of water heaters is helpful to reduce heat loss, because they heat water near your bath, shower, sink and there is less heat loss in the water distribution system. Therefore, they are much more energy efficient than other central water heater.
