heat a pool quickly after periods of intermittent shutdown, a larger
gas-fired heater is needed. And in colder climates a larger than standard
size heater also is recommended for "constant" heating.
Maintaining pool temperature requires the same amount of fuel regardless
of the heater size. For intermittent heating however, a larger heater
actually saves fuel because it brings the pool to temperature

are the differences between constant and intermittent heating?
what the terms imply. With constant heating your pool temperature
is kept at a comfort level, and your pool is ready for use at all
times. You set your thermostat at the temperature you want and forget
it. This is very convenient but more costly as more fuel is used to
maintain temperature in the pool at all times.
intermittent heating, you heat your pool only for those periods when
you expect to be using it. For example, if you swim only on weekends,
you would heat up the water for weekend use only and shut off your
heater during the week.
either heating method, the use of a good pool
cover can conserve heat and reduce fuel costs considerably.
pointers on intermittent heating?
intermittent heating generally effects greater fuel economy, just
as you would achieve by cutting off your furnace while away from home
for several days, even less heating is required with this method if
you keep a cover on your pool when it is not being used. A covered
pool stays warmer than an uncovered one. Shutting down your heater
for less than 2 or 3 days can be a false economy if you are not using
a cover because building pool temperature up again tends to offset
the "shutdown" savings. The less temperature buildup you
require, the less energy will be needed.
too, that intermittent heating requires a heater large enough to heat
your pool quickly when needed.
can we conserve energy and still fully enjoy our pool?
keep your thermostat at the lowest comfortable setting—and mark
this setting on your thermostat dial. Second, if you swim only on
weekends and are not using a cover, keep your heater on a standby
setting of 70 degrees. With a cover on
the pool when you’re not using it, you can leave the thermostat
at your normal setting. Third, if you’re vacationing for a couple
of weeks or more, or shutting down for the winter, turn the heater
off completely, including any pilot light. Fourth, use all available
means to prevent heat loss. Shelter your pool from prevailing winds
using hedges, other landscaping, cabafias or decorative fencing as
windbreaks even though the pool is covered. Finally, use a pool
cover whenever you are not using the pool.
a pool heater safe?
safe as any major heating appliance in your home. Teledyne Laars/
Jandy heaters, for example, are equipped with automatic safety pilots
or ignition safeguards, pressure regulators, water pressure relief
valves and other safety features. Shut-off controls are automatic.
Electric shock hazard is avoided by construction and installation
of the heater in accordance with strict electrical standards and codes.
Laars/ Jandy offers two types of gas-fired heaters. One has a standing
pilot and a built-in millivolt electrical system. The other has 24
volt solid-state electronic pilot ignition supplied by household current.
Both are as safe as your other gas appliances when properly installed.
Laars/ Jandy’ gas-fired models are design-certified by the American
Gas Association. Our oil-fired heater, which is internally grounded
according to the National Electric Code, is UL listed. Every Teledyne
Laars/ Jandy heater is fired up and fully performance-tested at the
factory prior to sale.
automatic is a pool heater?
you do is set it. For heating only at specific periods, a time
clock or electronic timers may be used for automatic shutdown
all gas-fired heaters built alike?
not. Some are built like an ordinary tank-type hot water heater, or
with heating coils inside the water tank. Teledyne Laars/ Jandy gas-fired
heaters were the first ever built specifically for pools. Our heaters
utilize the direct-fire method for greater efficiency. Patented stainless
steel burners heat finned copper tubes from which the pool water absorbs
heat as it flows through them. This simplified direct-fire principle,
first introduced by Teledyne Laars/ Jandy 40 years ago, makes our
heaters the most imitated on the market.
all oil-fired heaters basically the same?
Teledyne Laars/ Jandy oil-fired heaters are trim and compact, about
half the size of many other oil-fired heaters. But the most important
difference is that we have adapted our proven heat exchanger to use
stainless steel finned tubes to resist sulphur corrosion. The result
is efficient heat transfer with only minimal annual cleaning. And
these oil-fired models use our time-tested controls throughout—all
proven components for safe, automatic operation.
features should we look for in a pool heater?
should be concerned with economy of operation, reliability and durability. (continued........)
