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.
