Many homeowners are making the switch from a traditional tank-style water heater to a tankless water heater. Some may be doing so out of necessity because their old hot water heater has stopped working, and others may be making an upgrade to take advantage of the benefits that a tankless model can provide. Whether you are simply weighing your choices or you have already made the decision to move forward with the installation of a tankless water heater, it is important to know more about what you can expect from this type of water heater.

The Benefits of a Tankless Model
Many people consider a tankless water heater to be a green alternative to a traditional hot water heater, and there are indeed a few energy-saving benefits associated with these models. A tank-style water heater essentially will maintain a specified number of gallons at a specific temperature in the storage tank, and the unit will continue to heat the water whether you need it or not. You may not draw hot water from the unit all day while you are at work, but it will continue to use energy to heat it. With a tankless model, water is heated on demand. Because of this, energy savings can be considerable. However, the actual amount of energy saved will be based on the type of unit you currently have as well as the demand for hot water in the home.

What Else You Need to Know
You should be aware that a tankless water heater does not mean that you have an unending supply of hot water. It does provide you with a steady stream of hot water, but it can only produce so much hot water at a time. For example, you may take a shower for as long as you want without running out of water, and this is true even if the dishwasher or clothes dryer just finished running. However, if the washing machine, dishwasher and shower are all demanding hot water at the same time, there is a possibility that you may not have enough hot water.

When you are selecting a tankless hot water heater to install in your home, consider the amount of water it can heat at any given time as well as the type of energy used to heat the water. These factors will help you to enjoy the maximum benefits from your new hot water heater.
