FAQ ("Frequently Asked Question")

Q2: How long will the hot water last until running out?
A2: The answer depends on a few factors:

• your incoming cold water temperature
• the tank temperature setting (which can be set from 60°F to 140°F)
• the flow rate of the point of use. For example, if you are using it with a kitchen sink, then the flow rate is typically 1.25 GPM. If bathroom sink, then the flow rate is typically 0.5 GPM, less than half of a kitchen sink, and makes a big difference.
• how much cold water you are mixing in to get your preferred output temperature

Let's assume that your incoming water temperature is 70°F, tank temperature setting is at the maximum 140°F, it is installed under a kitchen sink, and you are mixing cold water at the faucet to get a skin-comfortable output temperature of 105°F (not scalding hot 120°F for example). Given all that, then the hot water will last about 2.5 minutes.
