the water. How much water you will be able to demand from your water heater at any given time will
depend on the model you have selected and your incoming water temperature. If you live in an area
of the country where inlet water temperatures average 55º F or you have cold winters, you will
probably NOT be able to run multiple large water demands at the same time, however, you will be
able to run all your hot water applications back to back without ever having to wait. You will enjoy
UNLIMITED HOT WATER. SEE CHART ON NEXT PAGE.
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.
