Product Description
This Smart Technology electric tankless water heater is configured as a “whole home” model for climates where incoming water temperature is 62°F and above. The ECO 18 is capable of heating over 2.5 gallons per minute, which is the equivalent of one water saver shower head (with a 1.5 gpm flow) and one sink with a low inlet water temperature of 62°F, and an output setting of 105° F. Two showers emitting no more than 1.5 gpm each can be run simultaneously when incoming water temperature is above 70° F. Digital temperature control allows you to set your temperature in increments of 1°. 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. However, when sized properly it 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 18 requires a minimum 150 amp electrical panel for installation with (2) 40 amp double pole breakers connected to (2) sets of #8 awg wire. Plumbing connections are 3/4″ NPT. For additional assistance please feel free to contact our support center at 877-474-6473.

The Stiebel Eltron Tempra 24 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 24 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.
