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.

What are the physical differences between the Standard H Series Gas 500000 Btu H500FDN and the Commercial 500000 Btu Heater 500000FDN ASME Besides the Bronze Header and two additional Years of Warranty & Parts. Also the previous 400000 Btu heater was using 1" Gas Pipe. Will the 500000 btu heater require 1 1/2" Gas pipe for a 65 foot run from an upgraded Gas Meter? My Pool is 43 L x 23 W x 54" Depth
Thank You
