Hayward builds a heat exchanger that completely heats all the water without allowing corrosive water to touch metal anywhere within the heat pump. The HeatPro's ArmourCoil-protected heat exchanger allows the water passing through the system to be heated and returned to the pool. Unlike copper or cupro-nickel heat exchangers, the AmourCoil heat exchanger is protected with an exclusive coating that isolates the metal from damaging, chemically-treated pool water, preventing corrosion and scaling, and providing a longer life for your heat pump.   Model # BTU Compressor Size Amps Diameter Height Price HP6002 81,000 3 1/4" ton 30 31 1/4" 40" HP11002 116,000 5 ton 50 31 1/4" 40" HP21002 116,000 5 ton 50 31 1/4" 40" HP21002C 116,000 5 ton 50 31 1/4" 40" HP2100TCO2 116,000 5 ton 50 31 1/4" 40" HP3100 116,000 5 ton 50 32" x 37" 33" How to Size a Hayward Pool Heater Installation and Operation Guide   Hayward Pool Heater Accessories     High wind stack   Indoor drafthoods HWS150 For 150,000 BTU heater HWS200 For 200,000 BTU heater HWS250 For 250,000 BTU heater HWS300 For 300,000 BTU heater HWS350 For 350,000 BTU heater HWS400 For 400,000 BTU heater   DHI150 For 150,000 BTU heater DHI200 For 200,000 BTU heater DHI250 For 250,000 BTU heater DHI300 For 300,000 BTU heater DHI350 For 350,000 BTU heater DHI400 For 400,000 BTU heater

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.
