Traditional water heaters consist of a large holding tank where water is stored and heated. All you have to do to access the water is to turn on the faucet and water will be released from the tank.

In theory, this is a good system. However, in practice, it is somewhat lacking in efficiency. Because the heated water sits around in the tank all day waiting to be used, heat loss inevitably occurs. As a result, the water heater has to keep heating the same tank full of water over and over again so that it is always ready to use. This can waste a significant amount of energy.

One way to get around this problem is by using one of the best tankless water heaters. These water heaters, which are a relatively new introduction to the market, are designed to heat water on demand rather than storing it in a tank. In essence, the water heater is added directly into your home’s plumbing system so that water passes through it as it comes into your home.

That means that if you turn on the hot water faucet at one of your sinks, the water is instantly heated the minute that it comes into your home. This is in contrast to having the water stored in a tank all day. Because the hot water is not sitting around waiting to be used, there is far less heat loss. This, in turn, means that far less energy is used in the process of heating the water.

One of the primary benefits of these water heaters is that they never run out of hot water. This can be a great advantage in homes where there are a lot of people who need to shower one right after the other. By heating the water on demand, you don’t have to worry about the last person in line having to take a cold shower. Instead, everyone can take a long, hot shower without ever having to worry that the hot water will run out before the last person has a chance to shower.

Despite their many benefits, tankless water heaters also have some drawbacks. For one thing, they can be somewhat difficult to install in older homes. In many cases, the wiring of your home may not be adequate to support the electrical requirements of the water heater. That means that the technician who installs your water heater may have to upgrade your electrical system at the same time which can add to the cost of installation.

All in all, however, tankless models are a far more efficient option than traditional water heaters. Because they heat the water on demand, they minimize energy loss as much as possible. This can translate into far lower power bills and much less wasted energy. Not only is that great news for your pocketbook, but it is also excellent news for the environment. Installing one of these heaters is a great way to minimize your home’s carbon footprint.
