This document provides information about geothermal pool and spa heating technology from Geothermal Innovations. It discusses how geothermal heating works by transferring heat from nearby water sources using a heat pump system. Geothermal heating is described as more cost effective than propane or natural gas, using renewable energy sources, and having lower maintenance costs. The document includes a case study comparing the costs of heating a sample community pool over 20 years using geothermal versus propane gas. It finds that geothermal provides savings of 81% over propane when purchased and 66% savings when rented.

2.  If you still heat your community’s pool & spa with propane or
natural gas, you’re working with obsolete technology and
wasting 70%-80% of your heating budget every year !
 Over the past 10 years, the price of propane gas has sky-
rocketed by over 128% leaving many communities scrambling
for a cost effective alternative to heating their pool & spa.
 Geothermal pool & spa heating technology has established a
strong and proven track record over the past 25 years clearly
making it the superior technology for the future of pool heating.
Are you still heating your pool with Gas ?

3. How Geothermal Heating Works
1) Geothermal Heat Pumps creates clean, sustainable and
environment friendly “free” energy by using the renewable heat
stored in the water of a nearby lake or through a pair of wells
we drill.
2) Through a simple heat transfer process using a Freon gas, a
compressor and a condensing unit, the heat that is stored in
the water is transferred to your pool thereby raising the water
temperature.
3) Geothermal will not only heat your pool in the winter, but it will
cool your pool in the summer giving you’re bathers a constant
“refreshing” swimming pool water temperature year-round.

5. Why Geothermal is the Best Choice
 It is intrinsically basic and dependable, with few moving parts.
 It only uses electricity to transfer heat not to create heat.
 It’s 6x’s more cost efficient than heating with Propane Gas and
 4x’s more cost efficient than heating with Natural Gas
 It uses “free” renewable energy .. no longer depletes natural resources.
 Efficient in all weather conditions and unaffected by air temperature.
 Replaces the copper in gas heater exchangers with Titanium
 Eliminates all copper staining of pool & spa surfaces from gas heaters.
 The system has a 20 year lifespan and when running is virtually silent.

14. Benefits of Renting your system
 No out-of-pocket investment as the all costs are rolled into one monthly payment.
 Payments decrease 2% each year - lowering the cost of heating by 35% overall.
 Community ownership of the geothermal system at the end of the 15th year.
 All repairs and maintenance associated with the heating system.
 Equivalent to purchasing when the cost of money is included at 6%.
 Installation of a wireless controller on the pool to monitor the temperature 24/7.
 Installation of gas heater ports which allows us it install a loaner heaters if needed.
 Our goal is to eliminate down time of your communities pool.
Rent or Purchase your Geothermal System
Benefits of Purchasing your system
 Break Even within 36 months with Propane Gas and 42 months with Natural Gas.
 80% Return on Investment (Excluding the cost of money)
 Immediate community ownership and control of the geothermal heating system.

15. Funding Your Installation
1) Draw from Reserves: If the community has a reserve fund available
that can be used to purchase the system, this is the simplest way for
board members to acquire the necessary funds for the project. The
reserves can then be paid back from the savings generated by the
geothermal system.
2) Special Assessment: This requires more effort on the part of the board
members to obtain the funds, but again, the funds will be repaid to the
community in about 3 years time.
3) Bank Loan: Some communities have a good working relationship with
their bank and can obtain funding. The only drawback is that banks
tend to look at the loan a “unsecured” so interest rates vary.
4) Renting from Geothermal Innovations: We will fund 100% of the
project so no “out-of-pocket” investment is required. The overall ROI is
about 15% lower than if community purchased the system outright
(when the cost of money is excluded from analysis).

16. Educating Community Board Members
 Understanding the Product: The average
board member is typically retired or semi-retired
and they have never been exposed to the
technology and many times their interests are
focused elsewhere.
 Price of the System: Even when faced with a
breakeven of 3 years and hundreds of thousands
in savings, funding the system via a community
assessment or bank loan is rarely met with high
enthusiasm so they tend to avoid it altogether.
 Service After the Sale: Obtaining competent,
reliable and timely service for the system. How
well your system performs revolves largely around
knowing when a problem occurs and the delay
time in resolving the issue.
 Warranty: Every board member wants
assurance that they have made a good decision
for their community. They express that need the
need of an “exceptional” warranty for the total
system purchased.
 Education is the only answer: Once they
understand Geothermal simply transfers “free
heat” stored in lakes or underground water
versus burning a fossil fuel to “create heat”
is a key step to moving them forward.
 Renting provides an easy solution: Our
Rental Plan requires No out-of-pocket
investment as the installation costs are rolled
into a monthly payment that produces saving
of 60%± over the life of the system.
 Service After the Sale: After the sale, the
strength of the product lies within our ability to
respond in a timely manner. Plus Aquacals
repair department can also service the
system giving added customer assurance.
 Warranty: We offer customers a Standard
Warranty of 5 years on the heating units & 1
year on remaining system. We also offer a
Premium Warranty with 7 year bumper-to-
bumper coverage.
