The answer is yes, if you want to enjoy comfortable swimming at your own convenience. One of the reasons for owning a pool is being able to swim when you want to. As for cost, that’s up to you. You really can control fuel consumption and waste simply by taking advantage of the suggestions made on this page.
Taking into consideration the need to conserve energy and to minimize fuel consumption, any unnecessary pool heating should be avoided. You are the best judge of the kind of use you want out of your pool. Use of your pool for recreation, exercise, therapy or just general enjoyment obviously will require heating it. Your pool won’t contribute to your health or pleasure unless it’s warm enough to swim in comfortably, and when you want to swim. Actually, using your home pool can be far less wasteful of energy and cost you less in fuel than driving to distant resort and vacation areas for away-from-home recreation.
For pointers on saving energy and cutting fuel costs, see the list of suggestions on conserving energy.
That depends entirely on you, of course. The temperature recommended for recreational and competitive sports swimming by the American Red Cross and many swimming coaches is 78° F. This comfort level coincides with good fuel conservation practice, too.
Young children, the elderly and others often need 80° F or warmer water, however, and hydrotherapy calls for warmer water, too.
Although 78° F to 82° F takes in about everyone, how warm you should keep your pool actually depends on personal preference.
You’re right; we call this extra time the “shoulder seasons”. The sun alone usually can’t keep your pool water at that comfort minimum of 78° F. By having a heater to warm your water you can add substantially to the daily use of your pool—and you can also extend your swimming season.
How much more swimming? From early morning to late evening, even with air temperatures of 65° or lower - if your pool is warm, you’ll swim more!
You can stretch your pool season by twice in most areas and even longer in other areas by having a heated pool. The usual 2-month season in Detroit, for example, can be doubled in time, and in Los Angeles the season can be more than tripled. In New York, Chicago and Philadelphia - double the season or better. In most regions, you can enjoy another comfortable month of swimming, or 20-50% more time each year in your pool! And always at the right
Again, it depends on your climate and whether you use a pool cover or not. Without a pool cover you’ll probably have a season of only one or two months in most areas and perhaps three months or a little more with a pool cover.
During those months when the average temperature in your area is high enough to heat your pool water to a minimum 75° F - and hold it there - you will be able to boost this temperature to 78° F or more if you use a good pool cover and keep it on your pool when the pool is not in use.
Pools that are not covered can lose 4° F to 5° F overnight in most parts of the country. With a cover, you can reduce that heat loss by 50% or more. So without a heater you should be able to use your pool in the afternoons and early evenings, in the warmest part of the season.
Remember that besides air temperature, you must consider such variables as wind speed and humidity, both of which affect the rate of heat loss from the pool. If your pool is not covered, try to protect the pool from breezes as best you can with walls, covered fences, shrubs, cabanas, etc.
Again, it depends on you and your personal pool temperature preference. It also depends on the climate in your area— and whether you use a good quality cover to conserve energy and heat.
Even using a cover, you’ll probably have to heat your pool a little, particularly during summer cool spells and for morning and evening swimming.
In Cleveland, Pittsburgh and Seattle, for example, even the July - August average temperatures are usually below 75° F and moderate heating would be essential for comfortable swimming. By contrast, average temperatures in summer are high and sustained. But "real" weather has a tendency to vary a lot from the mean, so it’s a good idea to rely on a heater to brighten up the cool spots and lengthen the swimming season.
A pool that is properly heated and properly used can contribute to and help safeguard health. Doctors and physical therapists regard swimming as one of the most beneficial of cardiovascular exercises. It is an exercise that nearly everyone can do safely, while running and jogging are impossible for many elderly people and those who suffer from arthritis and muscular diseases.
By heating your pool, you make it possible to engage more often in swimming exercise because you extend the hours and the season your pool may be used.
A heated pool prevents chilling and the problems caused by the loss of too much body heat. Pediatricians say very young children are especially susceptible to various respiratory infections which may result from repeated chilling, and this is also true of elderly swimmers.
A heated pool is a must for therapeutic benefits and when swimming for relaxation. Doctors and Red Cross swimming experts recommend pool temperatures of from 78° F for recreation and competitive sports swimming, to 90° F or more for certain physical therapy patients.
First, there is the initial or one-time cost of the heater you select and its hook-up or installation charge. Second, there is the monthly fuel cost, which varies with the type of heating system you buy, the use of your pool, the pool water temperature you prefer and other variables. Third, there is the matter of annual or semi-annual maintenance and service.
Operating costs can be kept to a minimum by installing an efficient, properly sized heater; using a good quality pool cover; and, of course, keeping your filter clean and your heating and filtering system well maintained.
Most certainly. A good insulating pool cover can reduce heat loss by 50% or more, depending on your location and climate.
A pool that is uncovered can lose up to 5° F overnight; a good cover can cut that loss by half.
Used at night or whenever your pool is not in use, the pool cover can help save fuel costs by cutting heat loss regardless of the type of heating you utilize. And it can even make an unheated pool more "swimmable" by helping to retain the sun’s energy that naturally heats the pool during the daytime.
A pool cover stops water evaporation when it is in place. It isn’t the water loss that’s the big consideration here, it’s the heat loss. Every gallon of water that evaporates from a pool takes with it 6000 BTU’s of heat in the process, and a typical uncovered pool loses 1 to 1½ inches of water a week through evaporation. For a 20 by 40 foot pool, an inch of water amounts to 500 gallons—roughly, a heat loss of more than 30 therms every seven days. (A therm is equal to 100,000 BTU’s).
Besides stopping heat loss, a cover saves on pool chemicals, too, by keeping them from evaporating with the water.
One Teledyne Laars/ Jandy heater can serve both your pool and spa. Our Model ESC heater is equipped with a switch that allows you to select either a spa or pool setting, so that with proper plumbing and valving you can heat the spa portion of your pool installation to the temperature you want.
Originally these spas were purchased primarily by people with specific physical disabilities requiring hydrotherapy. Today, however, the spa is recognized as a place where anyone can relax and enjoy relief from the stresses of daily activities as well as from aches and pains requiring hydrotherapy. The spa, built as part of the main pool, is walled off with its own water circulation system. Both can use the same filter and heater system with simple controls to switch from one to the other. A spa typically operates at about 100° F and provides a therapeutic whirlpool effect by means of high velocity water jets or bubbles.
It is important to know that use of a spa at high temperatures can be hazardous, particularly in conjunction with alcohol or drugs, or when a person is very young, very old, pregnant, or in poor health. The U.S. Consumer Product Safety Commission can provide guidelines for spa use. Consult your physician as to a safe temperature for you and your family.
Several—from the sun itself to gas-fired, oil-fired, electric and elaborate solar heating systems.
The most widely used type is the direct fired natural gas heater because of its low cost, reliability, ease of operation and the wide availability of natural gas. In areas where natural gas is not available, heater models can be furnished equipped to use LP gas or propane gas.
Oil-fired pool heaters are a good choice in areas where natural gas is unavailable but home heating oil is. Electric heaters are generally much less efficient and more costly to operate than natural gas heaters, unless the electricity is hydroelectrically generated.
Solar heating ranges from simple "passive" solar—the familiar pool cover that absorbs and transmits some of the sun’s energy to pool water—to "active" solar heating systems.
Used alone, the passive heating technique merely serves to help keep pool temperatures at existing levels by retaining natural solar heat and preventing its loss. It cannot add heat to build up water temperature beyond what the sun supplies. Active solar uses traditional pool motors to move water from the pool through a system of solar collector panels for heating by the sun. This increases the amount of solar heat added to the pool.
Not exactly—in fact, not by long shot. An adequate solar pool heating system can cost more initially than fuel-fired heaters. Solar 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 50% (100% is better) of the pool surface area. This means that if you have a 20 x 40 pool you may need a 20 x 40 collector area unless you have an roof with full, unobstructed sun for 8 hrs daily.
Your 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.
Solar heating systems heat slowly—and not at all in cloudy, cool or rainy periods or at night of course. 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 pump.
Size 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 gallons of water to be heated. Gas heaters run $1500-$2500, depending on size and who you buy it from. Installation costs vary by the distance from the gas meter, or propane tank, to the pool heater, but could be $500-$1500. For a $2-4K investment, you get considerably more use from your pool. If you have also decided on a spa, the piping to the pool is negligible in cost.
If 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.
It runs much 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. Note: The Laars oil heater is out of production, or no longer being produced.
With 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.
In 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.
Not 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. Pool heaters can be installed indoors with proper venting, but it is discouraged to do so, in the event that the heater exhaust or the heater itself began to leak carbon monoxide into an enclosed structure.
This 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.
Many common sense economies can be practiced—see our "Tips" section.
Studies of 10 - year "life cycle" costs have consistently shown that a good pool cover and a gas 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.
Heaters 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.
The 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.
Another 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.
To 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 more quickly.
If you have questions about heater sizing, consult your Teledyne Laars/ Jandy dealer.
Just 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.
With 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.
With either heating method, the use of a good pool cover can conserve heat and reduce fuel costs considerably.
While 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.
Remember, too, that intermittent heating requires a heater large enough to heat your pool quickly when needed.
First, 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.
As 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.
Teledyne 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.
Teledyne 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.
All you do is set it. For heating only at specific periods, a time clock or electronic timers may be used for automatic shutdown and turn-on
Definitely 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.
No. 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 sulfur 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.
You should be concerned with economy of operation, reliability and durability. Conservation of energy and fuel economy are extremely important—and an efficient pool heater can achieve both.
By eliminating wasteful heating, a heater can quickly pay for itself. For example, all Teledyne Laars / Jandy heaters are equipped with a sensitive thermostatic pool temperature control. It maintains the pool at the exact temperature desired without wasteful, long on-and-off cycles of heating and cooling.
Rust, corrosion and scale are the elements that deteriorate pool heaters fast. That’s why we make our sturdy 1-piece heater jackets rigid and strong, with single-seam welding and a new longer lasting, weather resistant coating that resists corrosion and ends flaking of finish. Our heat exchanger produces a scouring-action water flow that virtually inhibits scaling.
Yes. Salt water is highly corrosive, and a heater must be equipped with a special heat exchanger and other features to handle it. Teledyne Laars/ Jandy heaters designed for salt water use are available on special order.
Not with Teledyne Laars/ Jandy. Everything you need for convenient, efficient operation is part of the heater package. In our gas-fired models with pilot light, included are such features as the Visoflame pilot lighting device that puts the pilot where it can be seen for fast checkout and easy lighting. Series 2 model ESC heaters have an electronic temperature controller which provides two separate temperature settings for the pool and spa modes of operation. This model also has electronic intermittent ignition for even lower operating costs.
Not if it’s a Teledyne Laars/ Jandy. Usually, one maintenance inspection a year is sufficient to keep your heater working efficiently. Maintenance is largely a preventive measure used to safeguard your heater’s working condition. The ruggedness, corrosion-free construction and long-lasting finish of our heaters combine with simplicity of engineering to keep maintenance minimal.
This should always be done by a trained technician. For years Teledyne Laars/ Jandy has been conducting service training schools in all parts of the country for pool service companies and our dealers to assure the availability of highly skilled technicians wherever you live. On Long Island, Paramount Pools has been an authorized Teledyne Laars / Jandy installer and service center for over 28 years.
When you need them, we offer genuine factory parts through Teledyne Laars/ Jandy dealers. They are warehoused strategically across the nation to assure prompt replacement and repair regardless of where you live. Poolcenter.com has all the parts you would ever need. For other parts of the country, you can order them from us either over the phone at 877-766-5287, or right here on-line (see the heater parts section of this Web Site for complete exploded views of all Teledyne heaters).
The Magnuson-Moss Warranty Act and the Federal Trade Commission require that product warranties be clearly and simply stated—and that such warranties be available to consumers prior to purchase. Be sure you ask for and read all warranties.
Our warranties are available from the dealer or by writing the factory. A warranty accompanies each heater, along with installation and operating instructions and service manual.
Equally important is the reputation of the manufacturer. Teledyne Laars/ Jandy has been standing behind its products for more than 50 years.
For two reasons: The quality of your heater and the protection of your investment in it. Teledyne Laars / Jandy is the oldest and world’s largest gas pool heater manufacturer, with more heaters sold than all other brands combined. This is the result of engineering leadership that includes pioneering the first pool heater... the first stack-less model... the first line of heater to be fully approved for outdoor use... the first high-velocity flow-through tubes for heat exchangers... and the first truly compact oil-fired heater. This leadership is sustained by a large national organization of distributors, dealers and technicians.
Some heaters wear out in three or four years, but Teledyne Laars / Jandy heaters normally last a lot longer. A product life of 10 to 12 years is not uncommon. Heater failure is usually the result of some outside cause—not normal usage—provided it has been properly maintained.
Yes. Although a Teledyne Laars / Jandy heater can be added at any time, it should be included from the beginning, just as a heating system is installed during the construction of a home. This means greater convenience for you and less installation cost. When you include a heater in the beginning, it costs only 5% - 10% of your pool investment and usually gives you 100% more enjoyment from your pool. If the heater is not installed when the pool is built, provision should be made for a heater stub-out in the return water line, and space or a concrete pad should be provided for future installation.
For the sheer enjoyment of swimming in real comfort— any time you want. Any time of the day, any day of the year. Owners of heated pools would answer this question in far more glowing terms, but what having a heated pool amounts to is the satisfaction of getting more—much more—from your pool investment in terms of year-round family fun.
Keep a thermometer in your pool. It will pinpoint accurately the temperature most comfortable for you. Keep your thermostat at the lowest comfortable setting. Each degree more heat than needed could add more to your monthly fuel cost and use up more energy than necessary. Mark the "comfort setting" on the thermostat dial. This will prevent accidental or careless over-heating and waste of energy. Use the Temp-Lok feature to prevent over-rotation. Lower thermostat to 70 degrees when pool is to be unused for three or four days. For longer periods, shut the heater off. You will save money on fuel consumption and help conserve energy. Protect your pool from wind. Wind above 3 to 5 miles per hour can lower the pool temperature substantially. A hedge, cabana or decorative fence can be an effective windbreak. Use a pool cover when pool is not in use. This can reduce heat loss by as much as 50%. If you are vacationing for a couple of weeks or shutting down for winter, turn the heater off completely, including any pilot light. Drain heater completely prior to freezing weather. Freezing water inside the heat exchanger can result in costly repairs. Get a maintenance checkup annually. It’s your best ounce of prevention. Call your Teledyne Laars/ Jandy dealer for a skilled technician to do the job. The cost is minimal and the service will keep your heater working efficiently for many years.
