Heaters (cont.)

My heater whistles.....

Low gas pressure can cause whistling in the burners. Check your Owner's Guide or contact your installer.

Do Hayward heaters need heat sinks or a fireman's switch?

No. Hayward heaters cool down immediately after shut down.

What should my heater be set on?

All heaters should be installed on a non-combustible material, such as concrete or block. It must not have any structures above it, if installed outdoors, including tree branches within 4 feet. Consult owner's manuals for clearances around all four sides of your pool heater. 

Can Hayward heaters be installed indoors?

Yes, specific conditions apply. Please consult your owner's manual for complete details. They must be vented to the outside in a very specific manner, and have enough influent air to combust properly. Improperly installed pool heaters have the potential to cause fatalities from carbon monoxide emissions, or gas explosions.

How much fuel does my heater use?

Propane heaters use one gallon of fuel per hour for each 91,000 BTU's of heater input.

Example: A 250,000 BTU heater uses: 250,000/91,000 = 2.75 gallon per hour

Natural gas heaters use one therm (100,000) BTU per 100,000 BTU's heater size. Your gas is usually billed by therms.

How can I save on my heating costs?

1. Purchase an energy efficient model.

2. Use a solar blanket on your swimming pool when not in use.

3. Keep the temperature at the lowest comfortable position.

4. Remember to not turn up the heater to maximum, (it will not heat any faster) But set it at a known setting for your desired maximum temp.

5. Turn heater off or to a low setting during periods of non-use.

6. Wind is one of the largest heat thieves. Fences or shrubbery can reduce the effect that wind will have on pool heat loss.

Other Tips to Economize on Pool Heating - from Teledyne Laars/ Jandy:

1. Keep a thermometer in your pool. It will pinpoint accurately the temperature most comfortable for you.

2. 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.

3. Mark the "comfort setting" on the thermostat dial. This will prevent accidental or careless over-heating and waste of energy.

4. 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.

5. 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.

6. 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.

7. Drain heater completely prior to freezing weather. Freezing water inside the heat exchanger can result in costly repairs.

8. 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.
