Reasons to Consider a Tankless Water Heater

Most of us are familiar with storage tank water heaters, those hulking things in the basement that you were always told to stay away from as a child because it would burn you. Those kinds of water heaters have been the standard for many years. However, more and more people are making the switch to tankless water heaters instead. Why consider a tankless water heater over the traditional storage tank variety? Let’s take a look at some of the benefits to going tankless.

Energy Efficiency

The biggest reason for switching to a tankless water heater is how much more energy efficient it is than a storage tank water heater. Storage tank water heaters are designed to keep a large amount of water heated constantly in case someone in the home needs hot water. The problem is that this causes the water heater to be on 24/7, wasting energy on keeping water hot when there’s no demand for it. You’re still paying for all of that time that the water heater is running, but you’re only receiving a benefit when you actually use some of the water.

Tankless water heaters only activate when they receive a call for hot water. Once you no longer have a need for hot water, the water heater turns off until it’s needed again. This saves a great deal of energy, and therefore money.


Storage tank water heaters can produce a lot of hot water on demand, but the actual process happens very slowly. If you’ve ever run out of hot water in the middle of a shower, you know what I’m talking about. Every time a storage tank water heater distributes hot water, it takes in a little more cold water to replace it. The cold water is heated to the right temperature within a couple of hours, but in the meantime it’s going to be cold. So, even though you’d have to consume a lot of hot water to completely exhaust the supply, when multiple people are using hot water at the same time it can happen pretty easily. At that point, all you can do is wait for the water heater to catch up.

Tankless water heaters heat water much faster. Though they don’t store any hot water, and are thus easier to become overwhelmed if demand is very high, they also recover much faster than storage tank water heaters.
