Moreover, since a tankless water heater eliminates the ongoing thermal losses caused by storing hot
water in a tank, you will enjoy significant energy savings over a conventional water heater. When you use
hot water in your home with a conventional water heater, you need to mix a considerable volume of cold
water to cool the hot water down to a safe, comfortable level for showering and bathing, etc.
You need to do this with a traditional tank-type water heater because they are set at extremely high
temperature setting to prevent them from running out of hot water quickly. With our tankless water heater,
you will generally set the temperature at a much lower level since it is capable of heating your water on
demand. This level will be much closer to the actual temperature at which you feel comfortable showering
or bathing. Accordingly, when you use your faucet controls to run a shower or bath, you will no longer
have to mix as much cold water, in fact, you may mix very little or no cold water. This is perfectly normal
and means that you are no longer wasting energy and water by overheating your water.
SETTING THE OUTLET WATER TEMPERATURE:
The user controls on your new tankless water heater are very easy to operate. The digital display will
show your current set water temperature at all times that the water heater is running.
To set the temperature, start by turning on any water faucet. The digital display will light up and give you
the current temperature setting of the unit. To increase this setting, turn the control knob to
"Increase." or "Decrease." your temperature setting. You can set the temperature at any level between 80F
(27C) and 140F (60C). To change the digital display from Fahrenheit to Celsius, simply press the control
knob for 3 seconds.
Most people feel comfortable showering or bathing at a temperature between 98 and 105F (37 to 41C).
We recommend that you set the output water temperature of your water heater at either 105 or 110F
(approx .41 - 43 C). This will ensure you have adequate hot water to meet all of your household needs
while also maximizing your available water flow rate, reducing the risk of scalding to children and the
elderly, and increasing the energy savings you achieve.
Note: All newer model dish washing machines are normally equipped with an internal heating element,
and most clothes washing detergents are now designed for use in cold or warm water. There is no longer
a need set your water heater to a temperature above 125F. Temperatures above this level (which most
traditional water heaters are set to deliver) can cause serious scalding injuries to small children or elderly
persons in your home.
If you ever detect a water leak from your water heater, turn off the water supply at the shut-off valve on
the inlet side of the water heater, turn off the power to the heater and call us for technical assistance.
