    Get The Right Water Heater

    Jim Connors: Hi! I am Jim Connors from Rheem Water Heating. Today, we'll help you select the right gas tankless water heater for your home and discuss its operation and maintenance.

    When it comes to selecting the right tankless model, the first question to ask is how many hot water appliances, showerheads and taps might be operating in your home at the same time. There are online calculators to help you, but in general 199,900 BTU tankless model will support a three bathroom home plus an extra fixture, a 180,000 BTU model will support up to three bathrooms and a 150,000 BTU model will support up to two bathrooms.

    If you have multiple showerheads in a master bath or other high demand situations, an online calculator for selecting tankless water heaters will help your plumber choose the right model or models that you need to help keep your family supplied with hot water.

    For optimum energy savings, ask about tankless condensing models. On the average, homeowners own their water heaters longer than many other appliances. Making a wise energy choice now will certain pay off in the long run.

    Condensing models cost a little more than a standard tankless water heater, but are easy to install and worth the investment. If you're replacing an existing tank type water heater with a tankless, it may save on your installation charges if you install the tankless unit closer to your gas meter. A tankless water heater may require a larger gas line than the one you have now.

    Running a new gas line from your meter to your previous gas water heater location can be costly. If you're in an area that's not prone to freezing temperatures, consider a tankless model specifically designed for outdoor installations. You may save on venting and other related installation charges. We recommend that you have your tankless water heater maintained by a certified plumber annually. Annual maintenance helps keep it energy efficient and extends the life of your tankless water heater.

    As with all of these tips, be sure to consult your owner's manual or contact a professional plumber before beginning the project and to determine what might be the best option for you.
