But you can overwhelm the water heater by forcing it to provide hot water in multiple locations simultaneously, resulting in lukewarm water. With regular maintenance, tankless water heaters can last as long as 20 years—a significant return on your investment.

Keep in mind that it is wise to invest in a slightly oversize unit than buy the one that can’t supply enough hot water. It all depends on your location and groundwater temperature in your region, plus your requirements. There is an external temperature control knob on the front of the heater. Additionally, it features an abnormal temperature reminder that alarms if the inlet water temp is less than 37-degree F and the outlet temp is more than 167-degree F.
