Tankless Water Heater
Tankless water heaters heat water immediately when you turn them on, unlike traditional water heaters that require a tank to store water. By turning on your faucet to the warm or hot position, you activate the heating process. It is typically a better option than a water heater with a tank since you do not need to worry about the water being heated constantly while you are away or asleep.
It has been relatively recent for tankless water heaters to spread in the United States. Most Americans have traditionally used water heaters with tank-based storage. Water-heating alternatives have become increasingly popular due to the growing environmental consciousness of U.S. consumers.
Manufacturers and dealers in the U.S. have been looking to other parts of the world for solutions to meet this newfound demand. Since Japan and Europe have standardized tankless water heaters for quite a while, the stateside introduction of a tankless water heater has responded to this need. This guide is all about how long does the tankless water heater last?
Working of Tankless Water Heater
A tankless water heater performs several different functions compared to a tank-based water heater. Essentially, the former heat incoming water while the latter holds the house’s water supply. Tank heaters heat water continuously day and night regardless of whether you have a faucet running or a washing machine. During these idle periods, the tank produces heat that is known as standby heat loss.
Unlike a tank-based system, a tankless system suffers no standby heat loss since water is only heated when a faucet or washing machine is turned on at a warm or hot temperature. Tankless water heaters are therefore sometimes referred to as “on-demand” units by dealers and advertisers. Water heaters that use tankless technology do not lose heat when they are standing, which makes them more energy-efficient than conventional water heaters.

An exchanger, which accesses heat from another source, heats water on-demand in a tankless system by accessing heat from another source. The same type of heat exchanger can be found in air conditioners, radiators, and refrigerators designed to control temperatures.
Water is heated as it passes through electric coils or a propane-fueled combustion component, depending on the tankless system in use.
How long does a tankless water heater last?
Even the best tankless water heaters last for more than 20 years, which is undoubtedly longer than storage water heaters. They can also often last much longer than traditional models because they have parts that can be easily replaced. In addition to being good for the environment, prolonging the life of a tankless heater will keep it out of landfills, where most storage tanks end up.
As a result of their longer lifespans, tankless water heaters also come with more extended warranties. If possible, you should buy a model that has a long heat exchanger warranty.
Compared to storage tank water heaters, why do tankless units last so long? Why do tankless water heaters last so long? Scale builds up on storage heaters, causing them to become less efficient as corrosive minerals are baked onto the bottom.
Tankless water heaters are also more energy efficient in addition to being smaller. The majority are more minor than suitcase-size boxes that can easily be mounted on a wall, making them much smaller than conventional models.
Pros of tankless water heater
· An energy-efficient product
Depending on how much water you use, a tankless water heater can save between 24% and 34% more energy than a storage tank unit. Even doubling that amount will still result in higher efficiency of 8% to 14%. If you install tankless water heaters at all your hot water locations, you can save up to 50% on your energy bill. Compared to a water heater with a storage tank, this is a much better option.
Your energy usage is reduced, so you save money as well. The cost of an energy-efficient tankless water heater will be offset in just a few years if you live in an area with high energy costs.
· Friendly to the environment
There will be no greenhouse gas emissions from an electric tankless water heater. Electric tankless water heaters are far more environmentally friendly than other options- especially tank-based water heaters.
· Supply of hot water
With a tankless water heater, you can have hot water as long as the tap is running because cold water is heated at the time of demand. If you have a tankless water heater, you can take a hot shower for as long as you like without ever getting cold. In theory, there are some limitations, but you’d be able to take a long shower without getting cold.
In addition to being compact, tankless water heaters have no storage tanks and are a great option for those looking to create more space within their home.
Cons of tankless water heater
· Only gas/propane is used in tankless water heaters.
It requires stainless steel tubing, which may increase the cost of installation if your house doesn’t have such tubing.
· Carbon dioxide emissions.
There is an increase in greenhouse gas emissions from gas and propane tankless water heaters. Unlike tank-based water heaters, which require electricity constantly, this issue only occurs when hot water runs through the faucets.
· Possible replacement of gas lines.
Your pre-existing gas line may need to be upgraded to adequately fuel your gas tankless water heater if you choose a gas tankless water heater.
· Different circuits may be needed.
You might need an additional electrical circuit to run sure electric tankless heaters.
Heated water heater or tankless, which is preferable?
Energy.gov states that demand (or tankless) heating systems “may be 24% to 34% more electricity than traditional storage tank water heaters for residences that use 41 gallon or fewer of hot water daily.” The longer tankless water heaters are in use, the more money consumers will save (assuming they are powered by gas).
