Universal H-Series Low NOx Heaters
For In-Ground Pools and Spas - Electronic Ignition Dual Thermostat
Now With Cupro Nickel Heat Exchanger!
NEW Hayward Universal H-Series Low NOx heater combines industry-leading hydraulic performance; environmentally responsible low NOx emissions and a standard cupro nickel heat exchanger with a low profile appearance, lighter weight design, independent left or right side electric, water and gas connections plus 2" x 2 1/2" CPVC union connections to provide the ultimate installation flexibility for new or existing equipment pads.
It also includes a forced draft system that constantly moves air through the combustion chamber at a precise flow rate. As a result, all outside weather variables that can affect the heating performance, such as wind conditions, are eliminated - without having to install a high-wind stack.
NOTE: The Hayward Universal H-Series heaters meet the NOx Emission standards set by the California South Coast Quality Air Management Commission for 2001 and the Texas Natural Resource Conservation Commission Code.

Hi - I am trying to decide which propane unit would be best for me at an altitude of 6000 feet. We have an oval above ground 15 x 30 x 4 ft. deep pool. I have looked at the Hayward, Raypak, and Pentair units, but can't decide. Thanks.

Good day, Dawn, we would recommend the Hayward Pool Products Universal H-Series Low NOx Heater 250K BTU - LP for your set up. It can work with the high altitude and comes with a Curpo Nickel heat exchanger.

I bough a Raypak pump and filter last year after having had a Hayward for many years. Any issues with compatibility? Thanks.
Reply
Hi Dawn, as long as your system provides adequate water flow and they are not controlled by another brand automation system then there should not be a compatibility issue.

my pool heater is reading Lo,i had it set for 85 degrees it stoped heating
Reply
Hi Boland, most often the LO refers to the pressure switch, water pressure. This can be caused by either the diaphragm in the flow switch has failed or the filters are clogged and/or the pump is unable to make enough pressure to make the switch.

Hi Dennis, there are a few variables to consider when sizing a pool heater. Here is a guide that we put together called "Sizing Your Pool Heater" that should help.

How do you clear a CE error on display pad? How do you re-establish the correct communication between the ignition board and display board?
Reply
Hi, Nancy. You can follow these steps. A. Power down heater and re-power. This is similar to rebooting a computer. B. If rebooting does not solve the problem, inspect the display interface wiring. Ensure the display interface plug is securely attached to the control module. C. If steps A & B do not resolve the CE error, the Control Board - FDXLICB1930 and/or Display PCB - IDXL2DB1930 are defective and must be replaced.

I currently have an older model of this unit. I have a vertical vent pipe that vents through the roof. Can I operate this newer unit without the vent pipe?

Hi Alvin, This unit will also require a vent kit for indoor installation.

I want to change my CPS 1320 heater to a current model what do you suggest, roughly a 30000 gal pool

Im interested in a pool heater for an outside pool with following dimensions:
30 feet long x 10 feet wide 5.5 feet deep. I have LP gas, and would like to be able to use it in the fall temperatures may be -5 Deg Celsius. Will a 250 be suitable for this pool? I run a single speed 3/4 H.P. pump/filter Thanks!
Reply
Hi Emilio, Yes this heater would suit your needs. Based on the information you supplied on your pool you would expect to see a 1-2 degree (Fahrenheit) temperature rise per hour. In the colder months we would definitely suggest a Swimming Pool Solar Cover as this will significantly reduce your operational costs of the heater.

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't go wrong with this heater. Comes set for 240V but easy enough to change to 120 if you want. Control panel is straight forward. I got it for a great price at INYOPOOLS.com
