POOL HEATER SYSTEM

Abrégé anglais

All known gas pool heaters connect between the filtering system and the
jetting system.
They also are designed to operate continuously throughout the swimming months
to
maintain the pool water temperature within a degree of the user's settings.
In this invention, the pool heater is corrected between the filter and the
pool jetting
system with a two-way valve. Rather than jetting the heated water through the
normal jets
of a pool which is on the top of the pool, this pool heater has a hose that is
placed into the
bottom of the pool and jets the hot water into the bottom of the pool. This
system allows
the user to send the water to either the pool jets or to the bottom of the
pool. By sending
the heated water to the bottom of the pool, there is a far more efficient
transfer of heat
between the pool water and the heated water because the heated water will not
be
effected by the outside wind and/or temperature and the pool will be heated
from the
bottom up (heat rises).
In this invention, the pool heater is designed to function with a simple
barbecue gas tank
rather than a full time hook-up to a gas line that decreases the cost of
installation by
approximately $ 800.00.
In this invention, the pool heater is designed only to heat the pool water on
demand and
not to continuously maintain the pool water at a specified temperature. By
heating the
water and using a thermal heating blanket on the pool surface, the pool heater
will use far
less gas than if operated continuously throughout the swimming months.

Revendications

CLAIMS
1. Simple inexpensive pool heater constructed out of metal with no plastic
parts.
2. A pool heater defined in claim 1, in which the heated water is jetted to
the bottom of
the pool thereby decreasing the loss of heat from wind and decreasing the time
required to heat the water in the pool by heating from the bottom up.
3. A pool heater defined in claim 1, in which the heater does not required to
be
connected to a main gas line and is designed to function properly using a
simple
barbecue gas tank. This type of connections reduces the cost of installation
by
approximately $800.00 for the user.
4. A pool heater defined in claim 1. that is designed to be used only when
required to
heat the water and to be used in conjunction with a pool insulation blanket
(that is
sold separately) to maintain the pool temperature. By using the heater only to
raise
the water temperature rather than maintaining the water temperature constantly
throughout the swimming months, the user will benefit from far less costs
associated
with gas use.

Description

Overview:
Out door pools, both in-ground and above ground rely on the sun in the summer
to provide
the necessary heat into the water. In most instances, this heat source is not
sufficient to
maintain the temperature above 78° F. Since most adults prefer to swim
in a water
temperature that is above 80° F, there is a need for heating units to
increase the temperature
of the pool water to between 80° F - 83° F.
The most efficient pool heaters utilize natural or propane gas to heat the
water. However,
all the pool heaters that are presently sold require hook-up to either large
gas tanks or
directly to a gas line. The cost of this hook-up usually costs between $
800.00 to
$ 1,400.00.
In addition to the gas hook-up costs, the pool heaters that are on the market
are designed
to operate continuously throughout the season, therefore using a considerable
amount of
gas.
Therefore, we the applicants have designed and built a pool heater that does
not require a
gas hook-up and is designed for intermittent operation to raise the
temperature only when
required by the pool operators.

Since most pool operators have a insulation blanket for their pools, it is
only required to
operate our pool heater once or twice a week for a few hours. Our pool heater
differs
from the others presently sold in the following manner:
1. Our pool heater connects between the pool filter and the pool like others,
however,
the heated water is not connected to the normal pool jetting system on the
top.
Instead, our heater comes with a hose that jets the water to the bottom of the
pool.
This jetting system eliminates to loss of heat from the heated water that is
associated
with the wind on top of the pool. In addition, heat rises and therefore this
method
expedites the heating of the entire pool. During the heating process, it is
required to
place a thermal insulation blanket on the surface of the pool. This provides
additional
insulation and also expedites the heating of the pool.
2. Our pool heater uses a simple 68,000 BTU gas burner that is presently sold
on the
market and connects safely to a 20 Lb. Barbecue gas tank. This eliminates the
cost of
installation and allows for instant connection by all pool operators.
Description:
The pool heater uses a standard 68,000 BTU fish type burner mounted on a
stand. We
build a metal container to hold the copper tubing (heat exchanger) including a
chimney.
During operation the chimney does not exceed 110 ° F therefore
achieving an excellent
exchange of heat between the gas burner and the water traveling through the
copper
tubes.
Our pool heater is connected between the pool filter and the pool. The water
enters the
pool heater from the filter using the existing water pump. The water pump
motor has a
slight increase in amps that is 0.5 AIVB' maximum. The water is exhausted into
a hose
that is placed on the bottom of the pool thereby allowing the heated water to
enter the
pool on the bottom and the colder water entering the heater from the top. This
accelerates
the heating process because the heated water rises and is not affected by cold
wind.
We include a three directional 1 '/2" valve that is used to switch the water
flow between
the heater and the normal pool exhaust.
The pool heater can be connected to a standard 20Lb. Propane gas tank that is
used for
barbecues.
We have included sketches of our unit for further details.
