When you turn on the hot water tap, a source of cold water will enter the system, and the burner is ignited. The source of energy could be electricity or gas. Then the cold water goes through the flow sensor to the heat exchanger where it is heated to reach then wanted temperature. After that, the heated water goes out through the valve.

If you turn off the hot water tap, the unit will then shut down immediately.

  • It is more energy efficient than the traditional heater as there is no need to spend energy on storing hot water for a long time.

  • Also, it saves a lot of space with its compact design, and it’s not necessary to spare a space for a tank.
  • Finally, it never runs out of hot water as hot water is constantly made on demand.

And here are some of its drawbacks:

Things To Consider When Choosing A Good Tankless Water Heater

Size

The size of a tankless water heater depends on where you intend to put it and what you are going to use it for. If you want to put it under the sink to provide hot water for this area, you can choose a heater with small size. However, if you want a heater which provides water for a family to shower, you might need a bigger size.

Type

Gas

The gas heater is quite cheap to operate, especially when you mention about long term impact. You can also have hot water in a short amount of time and don’t have to worry about the inconsistency of the temperature. One main disadvantage of a gas tankless water heater is that you need to have gas pipes and venting. It also requires you to have frequent maintenance on the water heating system to prevent a gas leak.

Electric

This type of heater is very easy to install as it requires no extra equipment. You also don’t have to worry about explosive risk or combustible byproduct of the burning. It is the safest to use among these three types. Nevertheless, it takes longer for an electric water heater to heat up water. If several people need hot water at the same time, it’ll be hard for you to enjoy a constant flow of hot water.

Propane

This type of energy is less expensive than other types. Also, it has a higher BTU rating and can provide hot water in the shortest amount of time. However, you need to inspect the heater at least once a year for any possible leaks and soot buildup. It also bears a higher explosive risk so be sure to follow all of the safety guidelines carefully when you use this type of heater.

Cost

The cost will depend on which type of heater you go for, its capacity as well as it is modern. You need to pay for the unit itself, other supporting items such as venting and the cost of initiating the heater. There are quite a few deals on the market. However, since this appliance can affect the overall wellbeing of your family, you should think twice about a deal which is too cheap.

Water Temperature Rise

This specification measures the difference between the incoming water and the heated water’s temperature. It is more important if you live in a colder area. In this case, the water in your faucet is cold. Therefore, it needs a greater temperature rise so that you can feel comfortable. You can choose one heater that produces a little rise in water temperature in order to save energy. Also, if you live in a warm climate area, you might not need to heat up the water to a very high degree.

Gallons Per Minute

This number shows how much water your tankless water heater can produce each minute. Typically, a cheap unit will produce a lower number of gallons per minute. If you use the heater for heating water in the sink or individual use, you can opt for this option to save money.

Flow Activation

The flow activation of a tankless water heater shows how much water it needs to ignite the burner inside the heater. The more water it needs, the longer you need to wait before you have hot water.

In this case, you need to trade off with gallons per minute. The higher the GMP, the slower you need to wait.

Safety Features

There are additional safety features you can consider to ensure the utmost safety of your family. For examples, they are CO detector or automatic shut-down system.
