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.

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.

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!

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

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.

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
