Tankless water heaters come along with a host of additional benefits not necessarily found with a traditional water heater. However, while each of these systems primarily serves the same purpose, the way in which they function is relatively different. As a result, it is not always a situation of a one-for-one swap when upgrading from a traditional unit to a tankless option. Learn more about some of the factors you should keep in mind.
1. Proper Sizing
There is a common misconception that tankless water heaters are one-size-fits-all when it comes to their supply, but that is not the case. Tankless heaters are still designed and sized based on the amount of demand they can accommodate.
Additionally, if your current heater is older, it is possible that it is no longer equipped to meet your current demands. Choosing a tankless unit based on this old sizing guide will not work well for the long term. You will be far more satisfied with your new installation if you let a professional size the new unit for you.
2. Power Source Conversion
If your existing unit operates off of gas, double-check to see if it is also electrically powered, as some water heaters require both sources of power to function. However, there are also units that operate solely on gas. Yet, you want to remember that a tankless water heater still requires electricity to operate, even if it is a gas-powered system.
If your current configuration does not include an accessible electrical connection, you will need to take steps before the installation to have an outlet installed. If you are not sure, make sure you speak with a plumbing professional.
3. Updated Venting
Keep in mind that all tankless water heaters also require venting. This system will need to be set up as either a direct-vent system, which includes a system of circulating air inside and outside, or a power-vent system, which blows the air outside.
Whatever the design, a vent is necessary to ensure the heater functions properly and to protect the safety of your home and family. However, if your home is in a warmer climate and the heater will be installed outside, you will not need to worry about venting.
As you might imagine, changing from a traditional unit to a tankless unit will come along with several steps, but there is no need to worry. A trained plumbing professional is more than able to assist you, so be sure to reach out with any questions you might have.
