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.

I need to replace my heater and would like to control it from my Aqualink RS pad in the house. Does this limit me to a Jandy heater, or will it work with other brands?
Reply
No, There are plenty of compatible brands that will work with your system. They would just have to be wired for that.

It does an excellent job heating my pool. It is quick and turns off once it reaches the desired temperature. I love the digital display telling what the present temperature is.

(4 out of 5 stars) Hayward Pool/Spa Heater
Reviewed By: Moon Man from Columbia, SC ()
Pros: Great price for a pool heater with a cupro-nickel heat exchanger.
Cons: Heater is a little bulky. Warranty: there seems to be an industry 1 year standard for pool heaters. That sucks for a piece of equipment that cost about $2k or more.
Heats the pool very effectively and easy to operate. Has a cupro-nickel heat exchanger which is great for salt water pool applications.
