So, two MODEL 1 Water Heaters will only add 10 A to
the existing service load since 30 A was already
available for the existing 30 A tank. As a result, one or
more MODEL 1 Water Heaters will fit in most homes
that have a 150 or 200 A whole-house electrical service,
or can be installed using one or more subpanels with a
breaker that is sized accordingly.
POWER/VOLTAGE MODULATION:
During operation, the MODEL 1 Water Heater is
designed to use only the power necessary to heat the
water for various combinations of temperature rise and
flow rate.
DISCONNECTS AND SUBPANELS:
Electrical disconnect devices do not contain circuit
breakers and are not required by the National Electrical
Code (NEC) for residential appliances such as the
MODEL 1 Water Heater or any appliance rated less than
300 V. However, disconnects may be required by the
NEC for motor loads and for appliances with multiple
circuits in commercial applications.
Electric tankless water heater that uses
Ohmic Array Technology to heat water.
The MODEL 1 Water Heater provides
reliable, controllable and immediate hot
water either as a stand-alone water
heater or in conjunction with your
existing water heater.
Point of use and/or whole house water
heating. More than one unit may be
required for your application. Multiple
units must be mounted in series.
Maximum current draw is user
selectable in 5 A increments from 15-48
A. Maximum power output can range
from 3.1-11.5 kW, dependent on input
voltage.
240 V (50/60 Hz), and 15-48 A
Microprocessor thermostatic
temperature control adjusts
temperature 60 times per second.
The water source must fall within 150
to 1500 µs of conductivity. The only
way to accurately check the
conductivity of the water is to use a
conductivity meter.
