Hayward Pool/Spa Heater
Built for high efficiency heating with clean burning Low NOx (Low emission) burners and Cupro-Nickel heat exchanger for long lasting corrosion/salt resistant operation.
The Hayward Universal H-series Low NOx pool/spa heater combines industry-leading hydraulics performance; environmentally responsible low NOx emission and a standard cupro nickel heat exchanger with low profile appearance, lighter weight design. Water, Electric and gas connections can be reversed to either right or left side of the heater provide ultimate installation flexibility. Included 2" CPVC union connections for easy plumbing connection. The Hayward H-series Universal heater includes a forced draft system that constantly moves air through the combustion chamber at precise flow rate. As a result, all outside weather variables that can affect the heating performance, such as wind condition, are eliminated - without having to install a high-wind stack. Hayward H-series Universal heaters meet the NOx Emission standards set by California South Coast Quality Air Management Commission for 2001 and Texas Natural Resources Conservation Commission Code.

Propane Gas Usage Information
Liquid propane is externally compact and portable, but must vaporize to be released as a gas that can be used to fuel your heater. An insufficient gas supply causes reduced efficiency and poor combustion, which leads to soothing.
As a rule of thumb, Propane tank size should be 100 gallons for every 100,00 btu of heater rating.
If you're buying a Propane gas heater, the following information will help you decide how big a propane tank to select.
The rate at which a liquid propane converts to vaporized Propane gas is determined by many factors including: Humidity, Ambient Temperature, Surface Area of the liquid in the Propane tank. The "Rule of Thumb" for factoring these variables is to assume that a heater's Propane tank should be refilled when 60% of it's full-tank capacity has been used.

(BTU per hour - with 60 % Liquid in Tank)
Propane's ability to vaporize decreases with the temperature - particularly as the temperature dips below 60 o/F. On the other-hand, when the temperature outside is warm, say 85 o/F and the Propane tank has been 60% depleted, it will continue to provide sufficient gas flow for a while.
However, as the thermometer dips below 60 o/F, a Propane tank's ability to produce vaporized gas decreases sharply. In fact, as the chart above indicates, a Propane tank will yield barely HALF as much capacity at 20 o/F as it does at 60 o/F.
Also, keep in mind that cooler overnight temperatures can have lingering effect during the following day, causing the tank to not supply sufficient gas to the heater. "Low gas" conditions like these should be avoided, as they result in sporadic, inefficient operation.
Calculating a Propane heater's operating time
A single gallon of Propane will produce 91,000 British Thermal Unit (BTUs) in an hour. This fact coupled with the 60% usable rule of thumb allows anyone to determine how long a propane tank will supply enough gas to properly run a heater.
Calculating a Propane heater's operating time involves three-step formula illustrated below - though we should emphasize that these shortcut calculations are general in nature. The accompanying shortcut calculation are quite convenient, but are not foolproof method for estimating when a heater's Propane tank needs to be refilled. The safes method to use is the 60% rule of thumb.
AS propane tank is used or emptied, the tank contents steadily shift from liquid state to vaporized gas, reaching a point at which the remaining liquid propane no longer vaporizes enough to supply the proper amount of gas to the heater or appliance.
Calculating how long a full-tank of Propane will last
- Multiply the Propane tank's capacity by 0.6 (this is the "usable" Propane available with a full tank)
Step 1: Usable Propane = Propane tank capacity X 0.6
- Divide the heater's BTU rating by 91,000 (this is the gallons of Propane used in an hour)
Step 2: Propane Needed / Hour = BTU Rating / 91,000
- Divide "Usable Propane" (step 1) by heater's per hour gas demand (step 2)
Step 3: Hours of Operation = Usable Propane / Propane Needed per hour
The result estimates how many hours of operation can be expected for a specific BTU rating heater using a specific Propane tank size.
