Seisco Tankless Water Heaters

The Seisco is a very small but very powerful and extremely efficient electric tankless
water heating system. The Seisco, whose technology has earned 5 U.S. Patents and
many more foreign patents, is much more than just a water heater.

The Seisco was measured to be over 99% efficient by an agency of the Federal
Government.

The Seisco water heating system designs consider not only electrical, and plumbing
requirements of the application, but also location (space utilization), environment,
potential preheating enhancements such as heat recovery (including waste heat
recovery), solar, geothermal and more.

Seisco is the only electric tankless water heater,
which enjoys a patented power sharing distribution
method for activating the heating elements. This
method allows each one of a multiple of heating
elements to simultaneously provide substantially
equal amounts of heat to the fluid as it flows
through the heat exchanger. Other systems activate
the elements individually to full power one after
another, which creates hot spots in the heating
chamber particularly at shut down. These hot spots
literally boil the minerals out of the water creating
excessive mineral buildup and discharge. This
sequential activation used by other heaters also
loads (works) certain heating elements more than
others resulting in early failures.

Seisco is the only electric tankless water heater that controls power to the elements in a very unique and patented
power-modulating pattern. This feature insures that the use of the Seisco does not inherently create disturbance (flicker) in
the lighting circuits. This is very important since the proper temperature control for electric tankless water heaters depends
on modulating or instantaneously varying the power to high wattage heating elements. Without the Seisco’s patented control,
one can experience lights that flicker in the same fashion as if you were at your thermostat rapidly flipping the air conditioner
or electric heating off and on. It should be remembered that in any application the electrical service to the building should be
properly sized to accommodate the addition of all major electrical appliances including, the electric tankless water heater.
Some rural residences, even those that don’t have electric water heaters, experience light flicker even from hair dryers as a
result of inadequate or improperly designed electrical service to the house.
