| Efficiency diagram and tankless water closets from iFlush. |
|
We're
going to look at a little more serious product with the same name this month,
one recently introduced by WDI Products (China). This
iFlush
is a new flushing technology that doesn't use gravity or a pressure tank. Like
pressure tanks, it stores energy to provide a forceful flush, but instead of
that energy taking the form of compressed air, it uses a compressed
spring.
Performance
claims by the company stress the consistency of pressure applied to each flush
as compared to pressure tank types — always the same, regardless of supply
pressure. The company also claims quieter operation, and the ability to
flush efficiently with supply pressures as low as 11.4 psi. Consumption is
stated at 1.28 gallons per flush.
The
components will not fit into a conventional china tank, but are instead
designed to be incorporated into the base of a dedicated toilet
construction. The result is a "tankless" look.

While the iFlush toilet may be tankless in
appearance, it does have an internal tank. This next product innovation by
Vovo (Korea), doesn't even have an internal tank, but
rather, works solely with incoming line pressure (as low as 10 psi). How does
it do that? Who knows.
Using electronic controls, this toilet features
two flush modes in terms of water consumption —1.28 and 1.6 gallons. Depending
on the model, other features include:
"auto flushing," which
flushes when the user gets up from the seat (even does a short flush when the
seat is occupied less than 25 seconds)
a heated seat, the contour of which
is "ergonomically designed" (more squared in profile for folks with
similar bottoms)
a bidet function
night light
and a hand-held remote controller
(not sure if that handles all the TV cable channels and the garage door,
however). In the event of a power failure, manual controls are accessible
from a recessed area on the side.
