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.

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.

Can I use my existing inch and a half water pipe when plumbing in this heater? It will require downsizing from the 2 inch connectors.
Reply
Hi Steve, Yes it would be fine to go from 1-1/2" plumbing up to the 2" ports on the heater. If this was the other way around you may have problems (i.e. if you had 2" plumbing and you were going down to 1-1/2" for the heater ports).

I just set up my new pool and heater a few days ago. Everything was working fine for 3 days but then my heater display went blank. I checked all the voltages and fuses and that seems good. Anything else I should be checking? It's a Hayward H Series 250000 BTU Electronic Natural Gas Inground Swimming Pool Heater

It can be shipped to the Netherlands, but a big item like that we would ship to a port in the United States and you would set up a freight forwarder to ship the rest of the way. For items that do not need a freight forwarder would be shipped UPS Worldwide.

I am looking to replace an older heater with a natural gas heater 225,000 BTU range. I am looking for a heater that will also control my pump, so there is only one control panel. Is this something you sell?

Hi Phil, I'm not aware of any gas heaters that would control a pump. They're are some variable speed pumps that are available that has an auxiliary relay that can be used to provide power to a heater or other equipment.

Hi, David. This unit will be capable of heating an 18,000 gallon above ground pool but to size a unit properly we will need the surface area of the pool.

The picture of the Hayward 250 FDN you have on your web site shows a protective cover over the control panel, which is something I wished my current heater had I might have prevented the buttons to stop working. I have not seen this feature on any other web sites for this model, is the picture accurate and is there a specific model that has this that other web site are not showing?

Reply
Hello, A 3/4" gas line at 35 feet will only accommodate the H150FDN. For the H250FDN, you will need a 1" gas line.

Hi, does this unit come with an outlet plug attached or does my electrician have to attach one electrically?
Reply
Michael, The heater does not come with a cord. It is preset to 230v. It can also be wired for 115v. Your electrician would supply the cord when the unit is installed.
Reply
If I use a variable speed pump and it is programmed at low speed I assume the heater can be set to ON and the pressure sensor will shut the heater down. If, later, the pump speed is programmed higher will the sensor turn the heater back on? If so, does this cause any damage to the heater?
Reply
Hi, Jack. That is correct, the heater will only turn on when the water flow is within the operating range. This will not cause any damage to the heater.

Hi
I have an old Hayward 250 that heats a pool 16 x 32. I would like to buy a new one but have noticed that the gas line might not be large enough. From the meter there is 50’ of 1” then it changes to 3/4” for another 50’. The old heater worked fine with this for many years. Do you think a new H 250 would work with this gas line or is there another heater that would.
Thanks
Reply
Hi, I'm showing if you have a Two Stage Regulation System then you can use 1/2" gas line up to 150' from the outlet of the first regulator to the inlet of the 2nd regulator and then 3/4" gas line from the second regulator to the heater, not to exceed 10'. If you have a single stage regulator and you have 50' of 3/4" gas line then, unfortunately, you would need to go to a smaller 150,000 BTU heater like the Hayward 150,000 Universal Heater.

I am installing a 250,000btu Hayward pool heater outside. Installers said that since I am installing outside but close to windows I would need to vent upward passed the roofline. .

The installation instructions state that you should not install the heater within 24" of any outdoor HVAC equipment. Is this a requirement or suggestion?
What is the reason for this restriction? I do not see a similar restriction in the installation instructions for heaters from other manufacturers such as Raypak and Jandy.
Reply
Hi. This is a requirement. This unit draws air into the unit so that it can breathe or have adequate ventilation. If the unit is installed that close it will not be able to draw sufficient air into the unit suffocating it.

We just bought a 250 btu propane hayward heater for our 33 ft by 18 ft above ground pool. We are planning on using a T at our tank and run another line because the one to house is only three eights. We are planning on running another line half inch at a distance of 110 feet. We are planning on using 1/2 inch iron pipe also for last 10 feet. What size should the second regulator be and how far should it be from the heater? Can we use the half iron pipe for the entire distance?

Good day, at this time we are unable to advise on gas or propane installations. You or the installer would need to contact Hayward 908) 355-7995 (U.S.).

Hi,
I live in Napa California. Solar no longer does the job of heating the pool because of our cedar trees have grown so much that they cover the roof where the panels are. It's time for a gas fired heater. Here are my questions:
1. I believe the pool holds about 22,000 gallons. It is "L-Shaped" about 36' at the longest and about 16"across at the long narrow. What size (in BTUs) will it take to heat it up? The more BTUs, the faster it will heat up?
Hi, Thomas. To heat your pool efficiently, a 250K BTU will be the starting size. The larger the unit, the faster it will heat.
