more initially than fuel-fired heaters. It can add 25% to 50% to the
cost of building a pool.
systems have definite limitations. To begin with, they require sufficient
area in which to install large collector panels, usually on a roof
or deck overhang near the pool. Even in an area like southern California,
the total solar collector area needs to be at least equal to 75% (100
% is better) of the pool surface area. This means that if you have
a 20 x 40 pool you should have a 20 x 40 collector area available
for best results.
pump would have to work almost continuously during most sunlight hours.
This means your pump would be running during "peak load" periods
when the utilities’ generating plants are often taxed to capacity—and
when they charge more per kilowatt than during "off peak" periods.
heating systems heat slowly—and not at all in cloudy, cool periods.
Depending on the collector size and your location and climate, a solar
system may not be able to warm the water to your desired temperature,
even in the swimming season, except in the afternoon. And there is
just not enough solar energy to heat your pool for swimming in the
winter, early spring or late fall—no matter how many hours you
is the initial cost of a gas-fired heater?
for size, natural and propane gas-fired heaters cost the same. Prices
depend on heater size, which in turn depends on the size of your pool—the
gallonage of water to be heated. A good rule of thumb is 6% - 10%
of the total pool cost, if yours is an in-ground pool. And for this
small added cost you get considerably more use from your pool. If
you have also decided on a spa, the piping to the pool is negligible
you think of buying a pool in the same way you think of buying a new
car, consider a heater the same way as adding a radio or air conditioning
to an automobile. It’s an extra convenience you don’t
use all the time, but it adds immeasurably to your enjoyment. With
a pool heater you can swim anytime you choose.
is the initial cost of an oil-fired heater?
runs somewhat more than the cost of a natural or propane gas-fired
heater. An oil-fired heater is ideal in areas where home heating oils
are commonly used and natural gas is not available.
about installation charges?
natural gas-fired heaters, they consist of gas and water connections;
for models with electronic control, an electrical connection to the
filter pump circuit. Using propane gas requires a storage tank. With
oil-fired heaters, you will require the services of a trained oil
appliance technician and a storage tank. If your home already is heated
by either oil or propane, the installation probably can be tied into
your regular fuel supply.
some areas, gas companies will make the gas installation with only
a nominal charge. Check with your local gas utility and your Teledyne
Laars/ Jandy dealer.
we go to the expense of building a shelter for our heater?
necessarily - it all depends on whether you want your heater installed
indoors or outside. All Teledyne Laars/ Jandy heaters are design-certified
for outdoor installation without a protective shelter. The Series
2 gas-fired models can be used outdoors in the attractive "stack-less" configuration
in which they are shipped. They can also be installed indoors through
use of the accessory draft-hood, which directs combustion products
to a chimney or vent. The oil-fired models may be installed indoors
with proper venting or outdoors with chimney cap supplied.
about operating costs for fuel-fired heaters?
is largely up to you. Like house heating, pool heating can be regulated
to your budget. Swimming habits can be adjusted to your means. And
you probably will want to use a pool
cover to conserve as much energy as possible and still enjoy the
benefits of owning your own pool.
common sense economies can be practiced—see our
things considered, which method of pool heating is the least expensive?
of 10 - year "life cycle" costs have consistently shown
that a good pool
cover and a fuel-fired
heater combination is less expensive, overall, than an active
solar system alone, or active solar system and fuel-fired heater combination.
This is true, even state tax credits are allowed for installing the
active solar heater. Unless you live in an area where your electricity
is generated by water power (hydroelectric), it is also true that
the life cycle cost of a pool cover/fuel-fired heater combination
is much less than that of an electric heater or combination.
size pool heater will we need?
are sized mainly on the basis of the pool surface area and the difference
between the pool and air temperatures. The average air temperature
for the coldest month of pool use is used in the calculation.
heating load could also be affected by such things as excessive wind
exposure or much cooler night temperatures than daytime air temperatures;
in those cases a heater with more capacity may be desirable.
factor which may determine the size of the heater you will need is
the way you intend to use your pool. There are two common pool heating
practices — "constant" temperature maintenance and "intermittent" heating.
These are determined by how you want your pool heated—continually
or on an intermittent basis. (continued........)
