The 10 Best Tankless Electric Hot Water Heater Whole House

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.

Advanced Flow Control technology works by automatically adjusting the flow of water to eliminate unpleasant temperature fluctuation. What that means to you is a consistently satisfying experience every time, all the time !

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.

The Stiebel Eltron Tempra 29 Plus Tankless Water Heater features exclusive Advanced Flow Control™ German patented technology invented by Stiebel Eltron to automatically maintain water temperature for constant comfort. It’ll reduce flow slightly if hot water demand exceeds capacity to ensure that hot showers will never be interrupted. Tempra 29 Plus will typically use 15-20% less energy compared to conventional electric tank water heaters. Although, it’s possible to save significantly more energy depending on personal home usage habits. The difference is that conventional tank water heaters continually store hot water, and as a result, lose 15%-20% of the total energy consumed to the environment around them. This is called standby heat loss. Tank water heaters that use gas or oil are even less efficient, because they also lose heat through their vents to the outdoors. Our tankless water heaters do not need venting, and will not store hot water, waiting for you to use it. They operate on-demand to provide continuous and endless hot water when you need it, and not waste energy when you don’t. CERTIFICATIONS INCLUDE – ANSI/UL Std. 499, CSA Std.
