Model # H100ID1
Hayward has developed an induced draft heater for above-ground pools and spas that combines state of the art technology with ease of operation and superior performance.
Featuring an electronic, direct spark igntion system and an energy-efficient FireTile lined combustion chamber, the Hayward heater provides 100,000 BTU input, while delivering 81% thermal efficiency and quick heating.
An integral induced draft system makes this heater completely impervious to any high wind situations. A one-piece copper header/heat exchanger provides for leak-free performance. And a simple plug-in 120 volt electric cord is provided for simple installation.
Purchased H100Id1 gas heater, works great but sound like a small tea kettle whistling when burner kicks in. low water flow is not the issue.
Hi, J. You may have air in your gas line or have low gas pressure.
What does the water pressure Switch pressure have to be we cant get heater to start, We were told the is no water going through heater pressure sitch, But when tech held switch oen pump fired. Hearyer Model H100Id1
Hi, Jeff. The water pressure switch is activated with a flow rate of 20 - 70 GPM's.
What size heater would be sufficient to heat an above ground pool 12x24?
Hi. A 100,000 BTU unit will be sufficient to heat a 12'x24' above ground pool.
I have this heater in my new semi inground pool. Heater and filter are surrounded by fence and top has mesh, but floats are on top of mesh almost enclosing it. Is this okay for gas exhaust? Its a little stinky when i go in, but still definitely airy and in no way considered totally closed in.
Hi, Mark S. Unfortunately, that is not okay. This unit requires an unobstructed clearance at the top for ventilation purpose.
does a red blinking lite on the ignition module mean its bad ? H100ID
Luis, I was unable to locate a trouble shooting guide for this heater. I would recommend calling Hayward at 888-429-9273. They will be able to assist you.
i have a Hayward heater 100,000 btu heater and 10x18 pool. How many hours will I have to run it to heat to 82 degrees
Hi. You can expect a 1.9 degree temperature increase an hour using this heater to heat a 10'x18' pool.
Any reason this can not be used with a 9000 gallon Viking in ground fiberglass pool? Listed as an above ground heater.
You could use that heater, probably will not be too efficient, but you could use it. If you are wanting a natural gas heater I would recommend at least the H150FDN. For a pool, it will be most efficient to get a heat pump, part number HP21004T.
Which pool heater will be ideal for use with salt water?
Hello Manny- For salt water pool applications we highly recommend getting a Cupro-Nickel unit. The Cupro-Nickel heat echangers can take more abuse from minerals than the standard copper tubes. Here is a link to the Hayward units that are Cupro-Nickel. http://www.inyopools.com/heaters_hayward_lownox.aspx
I have been told by dealers not to heat my pool because the internal components deteriorate quickly, within a year to year and a a half, if the water Ph and chlorine levels are not perfect 24/7. Is there any validity to this?
That is true for saltwater pools. For saltwater pools, I recommend a heater with a cupro-nickel heat exchanger which extremely retards the corrosion factor. With chlorine pools a heater with a regular heat exchanger will last, just depends on amount of use.
Can I use an additional pool pump to run this type of heater ( separate from the filter pump)
Hi, You can but it will be pointless because you will need to add another filtration system to filter the water going into the heater.
My heater will not click on in the morning. I turn the on-off switch OFF at night. Should I leave it in the on position and just turn down the heat button all the way.
Hi, It's better to use the On/Off Switch when the heater is not being used. You will have to investigate the cause of why the heater is not turning on. The Hayward Heaters Above Ground Manual has a few troubleshoot tips you can try.
Can a propane heater be converted to natural gas?
Yes the Hayward H100ID1 can be converted to natural gas by using the Hayward H100 Propane to Natural Gas Conversion Kit.
does Hayward make a propane adapter for this heater
Fran, The conversion kit from Natural gas to propane for this heater is part # 6223-79
What size pool will this heat? I have a 18 x 33 above ground.
Your selection of heater size depends on many factors but primarily on how fast you want to heat your pool. This 100,000 BTU heater would raise the temperature of your 15,000 gallon pool roughly 3/4 degree per hour.
Does this heater hook up to a normal sized pool hose or do I need to buy adapters to change size?
This heater now has 2" couplings for the piping. If your pool piping has 1 1/2" piping, you will need to buy 2" to 1 1/2" adapters.
Can you use the H100ID1 Hayward pool heater on a salt water pool?
The H100ID1 can be used on a salt water pool. However, we would recommend a unit with a cupro-nickel heat exchanger. The cupro-nickel heat exchanger is much more durable than the copper exchanger used in the H100ID1. The H150FDN has a cupro-nickel exchanger and would be better suited for salt water.
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.
Can the Hayward H100 heater be converted from gas to propane?
Yes, to convert from natural gas to propane, you would need part #6223-79.
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.
