Ecosmart ECO 18 Electric Tankless Water Heater, 18 KW at 240 Volts with Patented Self Modulating Technology

$258.55$369.35$535.56
Last update was on: Sunday, January 5, 2020

Style:ECO 18

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.

iHeat Tankless S-16 240V 66A 16KW Stainless Steel Enclosure 7.2" by 11" by 3" 1/2"CPT 36′ AWG#8 Electric Water Heater, 7.5 lb

Last update was on: Sunday, January 5, 2020

Size:16 KW

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.
