Frequently Asked Question ("FAQ")
Q1: What are the temperature settings on the dial? A1: The dial has four positions: Snowflake (*), 1, 2, 125°F, and Max. ≈ The Snowflake setting is 50°F. This setting will protect water in the tank and pipes inside the unit from freezing. ≈ The 1 setting is approximately 105°F, but can vary a few degrees. ≈ The 2 setting is approximately 113°F, but can vary a few degrees. ≈ The Max setting is 140°F.
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. |
