1. Background
Present environmental and economic imperatives
support the more efficient utilization of
electricity the reduction of atmospheric
greenhouse gasses/ground-level air pollution and
the conservation of non-renewable resources (such
as natural gas). All of these energy-related
factors encourage the shifting of electricity
generation from peak usage hours to non-peak
hours. A superior Water Storage/Delivery
Technology has been invented to enable the
substantial amount of electricity now used to
heat hot water during peak hours (up to 5 of
peak generating capacity) to be shifted to
non-peak hours, and to encourage the substitution
of electricity for gas regarding natural gas hot
water heaters. Using lower-cost off-peak
electricity in conjunction with smart meter
technology or other timer approaches to
generate hot water at off-peak hours for use
later during the day time (peak) hours will make
substantial contributions to the environment, to
energy and power needs, and to economic
considerations.

1. Background (Continued)

• Hot Water Heating is Very Energy Intensive
  Accounting for up to 5 of Peak Electrical Power
  Generation in Ontario (e.g. Coal-Fired Power
  Plants) and Up to 20 of Individual Home Energy
  Costs
• Hot Water is an Ideal Energy Storage Medium to
  Shift Peak-Electricity Usage to Off-Peak
  Generation Periods
• Lower-Price Electricity at Off-Peak Periods along
  with Smart Meters (or timers) will provide the
  means and the incentive to utilize advanced hot
  water storage/delivery technologies.
• Hot water heating with gas is now at about the
  same cost as with electricity cheaper off-peak
  electric water heaters will provide substantial
  economic savings to existing users of gas water
  heaters (a benefit most likely to be exploited at
  the time of normal water heater replacement) -
  and will increase the asset utilization of
  installed base electrical generating/delivery
  infrastructure (i.e. at off-peak periods).

1. Background (Continued)
The Smart Meter
Recent studies demonstrate that the end-user is
very responsive to utilizing dollar saving
technologies, such as off-peak hot water
generation, once lower-priced off-peak
electricity is available.

2. Technical Description
The HAWT system enables water to be stored in a
water heater tank at an elevated temperatures
(e.g. 90 C) but reliably delivered to the
end-user at safe, non-scalding temperatures.
This approach effectively doubles the amount of
hot water that can be generated and stored at
off-peak hours (for a standard-size storage tank)
to provide all (or almost all) of the hot water
during the following day required by the average
home in Ontario. The basis of the technology is
a positive-displacement water blending
device. The HAWT water storage/delivery
technology is unique it is a passive,
non-reactive approach that is totally immune to
pressure, temperature, and flow
changes/perturbations in the water system.

2. Technical Description (Continued)
Shown on the left is an illustrative model of the
heart of the HAWT technology a positive
displacement (water) metering device. When
two such identical metering devices are
mechanically linked, the result is a fixed-ratio
water blending device. This simple approach
allows the elevated-temperature water in the
storage tank to be blended with cold bypass water
at an unvarying ratio to deliver safe,
non-scalding hot water to the end user.
9
2. Technical Description (Continued)
As illustrated in this page from the U.S. Patent
document, the HAWT Positive-displacement device
would be located on the outflow line from the
conventional-size water heater (and would blend
hot water there with bypass cold service
water). It is expected that the self-contained
blending device would be about the size as a
typical coffee-mug.
10
2. Technical Description (Continued)

• Only two (identical) moving parts are employed.
• The device is completely enclosed - there are no
  rotating pressure seals (that might otherwise
  present reliability problems).
• Construction can be based on inexpensive,
  mass-fabrication plastic extrusion
  capabilities.
• This device design exploits proven water
  metering technology for long-term reliability
  and dependability.
• There is no competing technology available
  anywhere that has the simplicity, inherent water
  meter reliability, and cost-effectiveness of
  the Patented HAWT technology.

11
2. Technical Description (Continued)
HAWT Hot Water Heater Technology Is Comprehensive

• Although the heart of the HAWT Approach is the
  positive-blender device,
• the technical development and business
  commercialization will focus on
• the provision of a comprehensive hot water
  heater technology.
• This technology will include
• Blender device (as described previously and as
  presently considered for
• additional technology advances new patents to
  be sought)
• High temperature storage tanks, along with
  special (e.g. low power heating elements
• and optimized design features)
• Electronic capability for integration with smart
  meters
• Expert system time-based electronic management
  to prevent depletion of hot water
• on excessive-use days or to allow function of
  system without smart meters
• Integral HOT WATER FUSETM to provide additional
  assurance of fail-safe functionality

3. Competing Technologies - Reference
Information
3.1 Thermostatic (Spring) Tempering Valves
The only competing technology to HAWT with
respect to anti-scalding valves ONLY is the
thermostatic tempering valve. This technology is
designed to actively adjust the mixing ratio of
the two (hot and cold) input streams of water to
provide the output stream at the targeted
delivery temperature. This technology is very
versatile because it continually adjusts the
control mixing ratio on the go to compensate
for the changes in the input water temperatures
that typically occur for industrial
environments However, this control-adjustment
complexity is NOT required for the special case
of hot water-heater requirements, where the input
water streams remain at constant
temperatures. Therefore, this continuous-acting
control feature of thermostatic valves is not
only unnecessary for hot water heater
requirements but is a critical deficiency
regarding control stability, reliability, and
safety.

6. Personal End-User Benefits (Continued)
The HAWT technology enables hot water delivered
to the end-user at a safe, non-scalding
temperature e.g. 115 F while eliminating
possibility of biological incubation issues
within the storage tank (that otherwise would
occur if water were to be stored at 120 F)

The scream point of hot water is 106 F. Yet
legionella bacteria rapidly incubates in water
from 90 F up to 130 F
Safe Hot Water Should Ideally be Delivered at
less than 115 F to prevent scalding injuries
But Stored at Greater than 140 F to prevent
biological incubation health hazards!

7. Summary of Business Case Information

• Utilizing Off-Peak Electricity Hot Water
  Heaters at Off-Peak Periods Saves the Consumer up
  to 200 annually, reduces green house gasses, and
  conserves natural gas resources
• Shifting Electric Hot Water Power Peak
  Requirements to Off-Peak Periods Eliminates
• 500 MW 1000MW in (Coal Fired) Generation
  Capacity and Enhances Asset Utilization of Base
  Power Generation/Transmission Assets
• The HAWT Technology is the Only Practical
  Technology for This Requirement Due to Inherent
  Simplicity, Reliability, Safety and Low Cost
• The HAWT Technology Provides Safe Non-Scalding
  Water to the End User for Advanced HAWT storage
  Tanks or for Conventional Tanks
• About 12,000,000 gas and electric water heaters
  are replaced annually in North America all of
  these replacements can beneficially and
  seamlessly exploit the HAWT Patented (U.S.)
  technology

26
7. Summary of Business Case Information
(continued)

• Water heaters and scalding issues are not
  normally a conscious consideration for most
  consumers. Therefore the retrofit opportunity
  for existing water heaters, gas or electric, for
  the specific purpose of prevent scalding is
  likely to be very small (unless mandated by
  municipalities).
• The retro-fit option for existing electric water
  heaters to only slightly reduce energy costs
  (regarding lower-priced off peak electricity) is
  also likely to be quite limited.
• The HAWT opportunity for electric water heaters
  at the time of water heater replacement is
  substantial, about 6,000,000 units annually the
  payback period is relatively short and the total
  payback amount is substantial (in addition to the
  anti-scalding features)
• The HAWT substitution of electric waters for
  replacement gas water heaters is substantial
  (about 6,000,000 units annually), for exactly the
  same reasons listed directory above
• The new-home HAWT water heater installation
  market is also quite important, perhaps 5 of the
  replacement market (i.e. 600,000 units annually).
