Induced Draft Heaters for In-Ground Pools and Spas
High performance. Low Nox. The new Hayward H-Series Low Nox Induced Draft Heaters feature a patent pending Finn Plate™ heat exchanger for constant heat disperse-ment, state-of-the-art pre-mix burners for environmentally friendly Low Nox outputs, hot surface ignition for instant and reliable fire up, and an advanced L.E.D. digital control panel for simple programming of pool temperatures.
It also includes an induced 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 IDL Series of heaters meet the Nox Emission standards set by the California South Coast Quality Air Management Commission for 2001.

Where can my heater be installed?
There are specific venting requirements and clearance distances that must be met to ensure proper operation. Consult the owner’s manual for exact specifications for your model of heater.NOTE: Gas fired heaters should be diagnosed and repaired by trained personnel.

What is the difference between an Electronic and Millivolt ignition?
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.
Will a gas heater operate at the low speed of a dual speed motor?
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.
How do you know if a pool heater is a propane heater or a natural gas heater?
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.
I currently have my pool heater hooked up in series with my pump motor, so that it turns off when the pump turns off. This heater has a digital control which I'm guessing needs power applied to it at all times. Does this mean I would need to hook the heater up to a separate circuit to maintain it's settings?
We spoke with Hayward and they stated that ideally it would be best to wire this heater to a seperate circuit but since this heater only draws .3 amps that you could wire this in series with your pump.
