Tank Vs Tankless Water Heater
If your water heater needs to be replaced, or if you’re building a home and are looking at water heater options, then it’s important to know about the options available to you. The two basic water heater options are tankless water heaters and tank (storage) water heaters.
The main difference between these two types is pretty obvious. A tank, or storage, water heater has a large tank that typically holds 30-50 gallons of pre-heated water. A tankless water heater has no tank and simply heats up the water you need when you need it. Tankless water heaters have powerful burners that heat the water very quickly.
Hearing that there are different types of heaters and then having to make a decision that will affect you for years to come can be a little scary. Once you know more about each type, though, your decision will be easier to make and you’ll be better equipped to make that decision.
Here are the pros and cons of a tankless water heater:
Here is more information about each pro and con.
Last longer- Tankless water heaters last for a long time. Typically, a tankless water heater won’t have to be replaced for 20-30 years, which is twice as long as a tank heater. Because these heaters don’t need to be replaced as often, you’ll get more for your money’s worth. When a tank heater breaks, it’s possible for the water to flood your basement. You won’t have to worry about that with a tankless heater.
Energy-efficient- Tankless heaters are more energy-efficient than tank heaters. Tank heaters heat and store water even when that water isn’t being used. Once the water cools down the heater will then just reheat it and so on until the water is used. This means that more energy is being wasted in keeping the water hot even though it isn’t yet needed. Tankless heaters don’t heat and store water unnecessarily, so energy isn’t constantly being wasted.
Takes up less space- Tankless heaters are much smaller than their storage counterparts. As you can imagine, a 30-50 gallon tank takes up quite a bit of space. Tankless heaters don’t have this problem. A tankless heater can be installed just about anywhere, such as under a sink, inside a closet, under your stairs, or even outside.
No need to wait for hot water- A tank water heater can only hold so much hot water. Once that finite supply is used up, it will take time to refill the tank and for you to have hot water again. A tankless heater doesn’t have this issue since the burner heats water very quickly and it’s available to you right away.
Expensive to install and purchase- One of the only drawbacks to a tankless water heater is that it’s more expensive than a tank one. Instead of spending a few hundred dollars on a water heater, you’re more likely to spend one or two thousand dollars on a tankless one. However, because a tankless heater will last longer than a tank heater, possibly twice as long, you’ll be able to save money over time.
Here are the pros and cons of a tank (storage) water heater:
Here is more information about each pro and con.
Cheap to install and buy- A tank heater will be much cheaper than a tankless one. However, keep in mind that you’ll have to replace a tank heater twice as often as a tankless one, so eventually, the cost will be pretty similar over time.
Cheaper maintenance and repairs- It’s also cheaper to maintain and repair a tank water heater. Even before you’re due to replace your water heater, chances are that something will break or need to be repaired. All you’ll need to do is call a water heating company or a plumber that specializes in water heaters.
Higher utility bills- Because of the heating, storing, reheating cycle of a tank water heater, you’ll have to deal with higher utility bills. This is largely due to the energy inefficiency of these heaters. Your utility bills may always be higher, but they’ll be especially higher in the wintertime when the water wants to naturally cool down faster and the heater must work harder to keep it hot.
Takes up a lot of space- Tank water heaters are large. Finding a place in your home to store a 30-50 gallons tank can be challenging. Many people keep their tank water heater in the basement, which may work for you depending on the layout and size of your home. Unfortunately, a tank heater cannot be kept outside.
Takes time to refill the tank- Tank heaters only have a finite supply of hot water. Once this hot water is used up it will take time to refill the tank and get more hot water. If people in your home like to shower right after one another or you like to run the dishwasher while someone is showering, then this supply of hot water will run out quickly and someone may be left screaming in the cold shower.
Needs to be replaced more often- A tank heater typically needs to be replaced every 10-15 years. This can be a hassle and can be a rather annoying problem. If you don’t want to have to buy a new water heater this soon, then maybe a tank heater isn’t right you.
Now that you know more about tankless water heaters verses tank water heaters, it may be easier to make a decision next time you face a broken water heater and need a replacement.
