How do you know if a pool heater is a propane heater or a natural gas heater?
Reply
Typically in the product name we use the abbreviation of "LP" for propane or "NG" for natural gas. Click here for a full listing of our >Pool Heaters.

Will a gas heater operate at the low speed of a dual speed motor?
Reply
Probably not - Most gas heater will shut off at low GPM levels (20-40) to keep the heater cores from overheating - 20 for 200 BTUs, 40 for 400 BTUs. Depending on your pool system you might get these GPM levels at the low speed but generally these heaters must be run at the motor's high speed.

What is the difference between an Electronic and Millivolt ignition?
Reply
The basic answer is that Millivolt is the old style of ignition, using a standing pilot light. While the electronic ignition uses a spark start system like a gas grill. Electronic ignitions are more efficient in gas usage and also are better suited for high wind areas where a pilot light might get extinguished.

Is a vent required for typical outside installation for the Hayward 150k Ng Lo Nox heater?
Reply
For the Hayward Lo Nox heater, you would not need to purchase an additional vent if you are using it outside. If you are installing the heater outside, we recommend you purchasing a heater cover. This will protect your heater from debris, rain, snow, heat- or pretty much anything that could get caught in your heater. The Weather-Out Pool Heater Cover can be viewed on our website.

Where can my heater be installed?

There are specific venting requirements and clearance distances that must be met to ensure proper operation. Consult the owner’s manual for exact specifications for your model of heater.NOTE: Gas fired heaters should be diagnosed and repaired by trained personnel.

I want to install the Hayward Lownox heater on my pool but I live in the mountains at 3,000 foot elevation; do I need to buy a special high elevation heater?
Reply
Hello George, The Hayward Universal Low Nox are self adjusting up to 10,000 feet of elevation. Any installation above 2,000 feet will require a special restriction plate to be installed. Luckily, that plate comes standard with every heater so no need to purchase it separately.

How long does it take to heat pool the size of 20x40x9 and what heater would you recommend??

Hi Jim, Unfortunately, we do not have the performance data needed to calculate the heating time for this unit. Your pool surface area is 800 sq.ft, so Hayward recommends a minimum size of 300K BTU, you can always go with a larger unit which will heat the pool faster.

I have a pentair intellitouch with screen logic, if I go with a Haward heater do I loose any functionality to my automation as compared to the Pentair 461201
Reply
Hi Kriss, Wiring this heater to the Pentair IntelliTouch will only give basic control like adjusting the temperature and turning on/off the unit.

I have 60000 gallons of water that I need to maintain at 82F. Can I do this with one 500000 btu heater or two. Currently I have one Laars 1000000 btu which I want to replace.
Reply
The H500FDN would do the job. It will not heat it nearly as fast as you are used to with the 1M BTU Laars, but it will do the job.

I have a 65,000 gallon pool and am planning to add a heater. Pluming was already designed to accommodate a heater addition along with 1 1/4" Natural gas line to the plumbing skid. My question is what size heater should I use? Should I tee my plumbing and do parallel heaters? My control logic is Hayward.
Reply
Hi Ryan, 1-1/4" gas piping would be the correct size for a propane heater, for a natural gas heater the correct gas piping size is 3/4".
Reply
I do have a 3/4 inch gas line, is that sufficient for that heater?
If not, can you recommend a heater which would work in a 3/4 inch line.
Thank you

Does the 500k model require a vent inside a pool house?
Reply
You would require an indoor horizontal or vertical vent adapter. Here is the Hayward H500 Vertical Vent Adapter and here is the Hayward H500 Horizontal Vent Adapter.

Yes, If used inside a buidling it needs to be vented

My heat will only run about 2 to 3 minuets then shuts off for about 5 min then runs again for another 2 to 3 min. runs on and off even though it has not reached its set temperature. Is that normal? or should it stay on longer, or until the pool water reaches the set temp?
Thank you

Hi, Miles. The unit should run until the desired temperature is met. The unit will need to be serviced to determine the issue if it's not provided you with an error code or message.
