Perhaps the time has come to replace your old, broken-down water heater, or perhaps you are building your new dream home and you are choosing which type of hot-water system to install.
You now have a choice between a traditional water-heating system that heats and stores water inside of a large tank, or a tankless water heater. Tankless systems are relatively new in the U.S., but Europe and Japan have been using them for decades.
Here are five very good reasons to go tankless:
With traditional hot-water tanks, families often had to ration the hot water or maintain a rigid schedule for showers. They had to schedule dish washing and laundry around how much hot water was available in the tank. With a tankless system, you can take a shower and wash clothes at the same time with plenty of water for both tasks.
2. Saved space
Traditional water heaters with 40 to 60 gallon tanks are around 60" tall and 24" wide. That bulky tank will take up precious real estate in a smaller home where space is at a premium. A tankless water heater, in comparison, can command the same space as a large computer, coming in at 20" wide by 28" tall and just 10" deep.
Because there is no large water storage tank, tankless units can be mounted inside the house on a wall, inside a cabinet, or in a closet. They can also be placed outdoors with an optional anti-freeze kit installed.
3. Saved money
Traditional systems heat and store water at a constant temperature 24 hours a day, whether you are using it or not. Even when insulated, hot-water tanks still lose heat, and have to call upon more energy to maintain the water at a constant temperature.
Tankless systems are more efficient because they only heat water as you need it. This will result in lower heating costs, shredding anywhere from 20 percent to 40 percent off your utility bill annually.
As a bonus, electric models do not produce any greenhouse gasses.
4. Longevity and reliability
Water tank systems typically come with a six-year warranty and have an average life span of ten years. That's adequate, but tankless units usually have ten to fifteen-year warranties and can last up to twenty years before needing to be replaced. It is conceivable you could go through two or three tanks before you replaced one tankless unit.
There is no possibility of flooding within your home because of a ruptured tank.
5. Clean water
Water tanks typically accumulate rust and scale as the years go by. The hot water it creates has that same scale floating around in it, waiting for you to use it for bathing or cooking. A tankless system eliminates that circumstance, and delivers cleaner, fresher water right to you.
With all of those benefits, one might wonder why anybody would use a traditional water-tank model. One of the biggest challenges that people who want tankless systems must face is that the up front costs are significantly higher than a standard tank heater.
In a typical two-bathroom home, a tankless water-heating system can cost two to two-and-a-half times higher than a standard water heater to purchase and install. You may need to install a larger natural-gas line to supply enough fuel to the unit.
However, there are ways to save on some of those costs. Many propane tankless water heaters are eligible for a $300 federal tax credit. There may be other state and local rebates that apply as well.
Remember a tankless system will last twice as long, so if you intend to live in that home for a significant amount of time, a tankless model is a great long-term investment.
