Which Is The Best Instant Hot Water Heater Whole House

Professional classic® tankless electric water heaters offer continuous hot water quick and on demand for single point-of-use or multiple applications

The heat electric tank less water heater S-16 model has the capacity of heating 3.5 gpm which is the equivalent to 2 showers (at 1.5 gpm each), and 1 sinks (at 0.50 gpm each) simultaneously, or any combination which equals to 3.5 gpm. The S-16 can handle these applications in the warmer climates of the us which are Florida, Georgia, Louisiana, Texas, Arizona, California, Alabama, and Mississippi. Anything north of these States the S-16 model can be used for point of use, or 1- application at a time. A good rule of thumb is if you live in the southern States mentioned here the S-16 can power a 3 to 4 bedroom 2-1/2 bathroom home, including dishwasher and clothes washer, please keep in mind that tank less water heaters are designed to heat incoming water at a maximum output temperature based on simultaneous use and inlet water temperatures. So if your demand for hot water decreases your output water temperatures will increase, as well as if you live in the colder States this S-16 will heat less volume of water, this will cause the S-16 to be used in point of use applications in the colder climates.

Product Description

This Smart Technology electric tankless water heater is configured as a “whole home” model for climates where incoming water temperature is 67°F and above. This model is well suited for heating up to 2-Gallon per minute, which is the equivalent of one shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 67°F and an output setting of 105°F. Digital Temperature Control allows you to set your temperature in increments of 1 Degree. This model can also be used in colder climates as a Point of Use for a sink or other low flow application. All tankless water heaters are sized based on flow rate and temperature rise, and there is a direct relationship between the two. So if used in a cold area requiring a high temperature rise, it will be more limited in the amount of fixtures (gallons per minute) it can heat at one time compared to a warmer climate. When sized properly this water heater will provide endless hot water and only consume the energy needed, giving the user complete control. Prior to purchase and installation please verify this model is the right size for the expected demand and electrical requirements. The ECO 11 requires a minimum 125 amp electrical panel for installation with (1) 60 amp double pole breaker connected to (1) set of #6 awg wire. Plumbing connections are 1/2″ compression fitting with the option of 1/2″ NPT adapter included. For additional assistance please feel free to contact our support center at 877-474-6473.

NOTE : 11Kw at 220 is equal to 13kw at 240.

Question:
Why the water is not hot?

1.The working current of our water heater is 25A-32A, and it require at least 1.5 square millimeters of wire. Please make sure that your circuit breaker can handle the 30amp, or it will not heat water.
2.The temperature is controlled by the size of the water flow. The Water Heater will be automatically energized when the water flow is more than 0.6 liters, and automatically turn off when the water flow is lower than 0.4 liters.
3.The heating temperature is between 30 and 55 degrees. If the water flow is large, the temperature will be low, and if the water flow is small, the temperature will be high.
