The US Department of Energy says that residential tank storage heaters are the highest energy
consuming home appliances only second to heating and air conditioning systems. It is consuming
more energy than your refrigerator, dish washer, washer and dryer combined. If you have a
traditional tank style water heater in your garage, attic, or basement and older than 9 years NOW is
the time to upgrade.
Tank-less Water Heating is the futurist solution — now Maxwell electric tank-less water heaters
available in 99% efficiency to save you up to 50% in energy consumption, enjoy endless hot water
without any recovery time, and significant space savings.

Proven and Reliable Technology
Traditional tank and conventional tank-less water heaters heat the water directly using immersed coils. This type of design causes
heat spots, lime scaling, and mineral deposit build up that affect the heating capacity, and reduce the efficiency. Since there is not
water storage and traditional coil heating element in the Maxwell heaters their efficiency improves and the product life is doubled.
The Maxwell heaters are built with a stainless steel water flow channel inside single piece aluminum cast that further increase their
service life. Precise digital control provides an endless hot water supply at constant temperature.

How Maxwell Tankless Water Heater Works
Undisputed twenty two years of heating
experience and engineering has applied
to develop the Maxwell tankless water
heaters delivering many years of reliable
water heating in your home or in
commercial applications. Below is the
explanation to help you to understand
and to familiarize with the operation of
Maxwell electric tankless water heaters.
1. Once you turn hot water faucet on,
cold water flows through the unit passing
thru a flow meter and inlet temperature
sensor that measure the precise flow rate
and temperature of the incoming water.
2. Advanced micro-processor control
monitors and senses all working
conditions of the heater and switches
devices to fully modulate the power of the
heating elements from 0-100% to provide
the most precise and consistent hot water
temperatures in the industry.
3. The micro-processor engages heating
elements in stages depending on the
demand requested by the amount of the
water flow and inlet water temperature
using solid state switching triac. Power is
always regulated to avoid excessive
startup surge.

Water Outlet

4. As the water flows out of the unit the
water is being heated in the patented
multilayer heating chamber and a
second sensor at the outlet makes any
necessary adjustments to ensure
Maxwell tankless water heater delivers
accurate and constant temperature hot
water.
5. System continues to operate and
remains on until no flow is detected then

goes to stand-by mode until any hot

6. Maxwell advanced micro-processor
has numerous features to monitor and
control with self-diagnostic functions and
displays the working conditions, the
outlet water temperature, working time
and the kW power consumption to
enable the homeowners to optimize the
usage of the heater and maximize
savings, and gain the most benefits from
their investment

There are many factors that go into selecting the right water heater: the number of people in the home, type
of showers and tubs, water pressure and geographic region. To make the process easier, we offer the map
and flow-rate table below.
1. On the map, determine the ground water temperature in your area.
2. In the corresponding column select the water heater based on how many fixtures you'll be running
at the same time.
3. The temperatures shown above are based on the average coldest ground temperature in your region.
