    Frequently Asked Questions

    Should I get a storage water tank or a continuous flow?

    Storage tank systems are considered the traditional system. In this type of system, water is stored in a tank that is kept to the proper temperature. The problem is that tanks can corrode over time and need to be replaced. However, you can also get stainless steel tanks that last much longer.

    With a continuous flow system, the water is heated as it passes through the unit. You never have to worry about running out of hot water, and there is not the extra cost of heating the water tank when it is not in use. Many people are now choosing a continuous flow system, but there are still some that prefer a tank for different reasons.

    To make an informed decision, it’s helpful to read instantaneous gas hot water system reviews, instantaneous hot water system reviews, and continuous hot water systems reviews. These reviews can provide insights into the performance of various models, such as the Rinnai Infinity 26, and help you identify any potential problems or advantages associated with specific systems.
