View larger image
With our Large Electric Tankless (on demand)
Hot Water Heaters (ECO 21, ECO 24, ECO 27), you will enjoy endless hot water, when you want it, and only
when you need it. Go Tankless and Save!
These are the most powerful Smart Technology electric tankless water heaters on the market. They are configured for cold climates where the incoming water temperature can drop below 45°F. They are well-suited for:
◊ homes in the northern US and Canada,
◊ homes in the Southern US that have large Roman-style or Jacuzzi tubs, and
◊ homes that have generally more demanding water usage needs.
Maximum Flow Rate Desired: You should consider the maximum flow rate
you really need or use. See chart for flow rate guidelines for various
hot water applications in the home. The average shower temperatures are
between 98°F to 105°F. To determine which model you need, determine how
many hot water applications you run at the same time. Add up the flow
for them. This is your total flow rate. On the chart below, find your total flow
rate, and your inlet water temperature. The model on the left column is
the best model
for you.
The chart below shows flow rates for all our models based on inlet temperature with temperature control setting at 105°F.
For example, if you typically use about 3.5 gallons per minute (two
showers
with water saver showerheads) at the same time, find the 3.5 GPM on the
chart or the number closest to it. If the number is highlighted in GREEN, that means it is the correct
model for you. It it is highlighted in YELLOW,
that means you can get by with it. If it is highlighted in RED, you should consider a model a step
or two up.

size and wire gauge must meet all applicable local, state, provincial,
and national electrical codes for your area. These are only guidelines
that will apply to most installations. Some codes require use of
electrical sub-panel for installation, especially when heater is not
mounted within line-of-sight of the main electrical panel. Wiring should
be sized to maintain a voltage drop of less than 3% under load.
The above
specifications are only guidelines. If your home is already equipped
with a large number of electrical appliances, you may require a larger
electrical service than the one recommended above. Please consult an
electrician before placing an order.
Maximum Flow Rate Desired: You should consider the maximum flow rate
you really need or use. See chart for flow rate guidelines for various
hot water applications in the home. The average shower temperatures are
between 98°F-104°F. To determine which model you need, determine how
many hot water applications you run at the same time. Add up the flow
for them . Use the charts to determine the flow rate for those
applications and your inlet water temperature to determine which model
is best for you.

Tankless Water Heaters
Currently the United States is the world's largest energy consumer and for that reason is also the largest source of global warming pollution. The U.S. emits more carbon dioxide than China, India and Japan, combined. 25% of the carbon dioxide pollution produced by the U.S. comes from fossil-fuel burning. By switching to more energy efficient appliances and equipment as ECOSMART Tankless Water Heater, we can reduce the use of electricity and cut carbon dioxide pollution produced from power plants. When it comes to water heating, you won't find a higher performing, more efficient and better quality tankless water heater than the ECOSMART Tankless Water Heater.
