is this the same size or benefits as the raypack 2100 model im replacing the one im replacing was catalog number 6000.52aa iso 9001

A  Answered on 12/4/2020 by InyoPools Product Specialist Joe S.

Good afternoon, Frederick, in order to provide the best information we would need more information such as a photo of the data plate on your current unit and the Gas line size used between the heater and the meter. You can send that information to INYO Pools Customer Support.

Can i control this heater through my Jandy board iaqualink 2.0?

A  Answered on 11/13/2020 by InyoPools Product Specialist Joe S.

The digital model heaters are equipped with the ability to work with external remote controls. The supplied 7-pin remote wiring connector supplies power out to either a toggle switch or the switch contacts of a third party remote. The remote works by either making or breaking the circuit created by the remote wiring. Typically, a remote does not supply power to the heater, it only provides a switching function to turn the heater On or Off. If your remote is suppling its own voltage to the heater, it will not work with this heater and may damage the digital circuit board

Is this a commercial pool heater or is it a domestic heater? Do you have a recommendation for a commercial pool heater that will be running year round? The pool is 30'x13' and ranges in depth from 3' to 5'.

A  Answered on 10/23/2020 by InyoPools Product Specialist Joe S.

Good day, the 009216 would be for residential installs. If you need a commercial unit it would be the Raypak Heater 206BTU NG ELE ASME - 009268.

Our pool is a vinyl 16x32 inground pool. We had a natural gas heater prior , it lasted about 7 years and we recently removed and got rid of it. Would this be a good fit for us.?

A  Answered on 11/20/2020 by InyoPools Product Specialist Megan C.

I am not sure what the total gallons is, I will need the average depth of the pool and the shape of it to calculate total gallons. An example; if this pool is 20,000 gallons the minimum BTU size to install is 167K BTUs. If you selected to order the 206K BTU for a 20K gallon pool it would take approximately, 1-hours and 10-minutes to raise the temperature by 1-degree.

I have a Raypak P-R406A-EN-C pool heater and want to replace it. We use the heater for SPA only. We live in California. Can Raypak P-R206A-EN-C be used to replace? What would be the specific model that we should look to replace the original 406 model? Just want to make sure we are able to use the existing gas and water pipe connections.

A  Answered on 2/10/2020 by InyoPools Product Specialist Lennox H.

Hi, Vivek. Keeping the P-R406A-EN-C allows you to use the existing gas and water pipe connections. Replacing it with a smaller unit will require you to have to change the gas line size and regulate the meter.  

?     Asked on 12/11/2019 by jeff Woodruff

Thinking of buying the 206,000 btu heater. Natural gas meter is 85 to 100 feet from water heater. Pipe size is 1" Trac pipe. Is this gas pipe big enough to supply. We are replacing a 175,000 btu heater.

A  Answered on 12/13/2019 by InyoPools Product Specialist Kevin G.

Hello,Thank you for contacting Inyo Pools. The longest gas line you can use with 1" and natural gas is 90 feet. If your piping is longer than this, you will need to go with a smaller heater or increase your gas line size.

On breezy days the flame is frequently extinguished. Is there an easy fix for this?

A  Answered on 10/2/2019 by InyoPools Product Specialist Steve M.

Andrew, unfortunately, there is not an easy fix that we can suggest in most cases you have to reorient the heater unit. If you would like, maybe call RayPak and ask their technicians if they have a quick fix. They can be reached by calling 805.278.5300.

?     Asked on 5/24/2019 by Pennee

I have a Rayvac 2100 digital pool heater that has a leak. Is this something that can be repaired or do I need a new heater. Leak is coming from somewhere inside the heater. While pool is running, there is a steady dripping water leaking out. Who do I contact for help or what should I look for?

A  Answered on 5/25/2019 by InyoPools Product Specialist Lennox H.

Hi, Pennee. Resolving the issue of a leaking heater could be as simple as replacing bad o-rings or as severe as replacing the entire heat exchanger. The unit will have to be inspected to determine the cause of the leak.

Hi, Ronald. You can replace the LCD Display - 013640F if your unit has P.C. Board P/N 013464F manufactured after 05/11. If not you will have to replace the entire P.C. Board P/N 013464F

I just have had one of these fail with some kind of fire that has burned the wiring and cracked the heater manifold. I'm using a salt/chlorine generator system that has always been within expected ppm limits. Is there a problem using a salt system with this heater?

A  Answered on 2/26/2019 by InyoPools Product Specialist Lennox H.

Hi, Scott. There is not a problem using this model with a saltwater pool. However, the cupro-nickel model 014938 is the recommended unit for pools with saltwater.

I have a 30'x12' inground pool. The pool goes from 3-6ft in depth. Currently I use a Natural Gas 181,000 BTU Pool heater. The product is a Raypak RP 2100 Mullivolt Plus. I am trying to order a new heater but do not want to change the size of the gas pipe or water connections. Is this the best solution for that? Is this the most efficient size?

A  Answered on 4/5/2017 by InyoPools Product Specialist Lennox H.

Hi, Carlo. Yes, replacing your current RP2100 with a new RP2100 would minimize having to change plumbing and gas pipe connections. This is an electronic unit, not a millivolt so you would have to run power to this unit but is the smallest BTU unit available. The p/n for the millivolt unit is 009192.

My house is at 5,600 feet elevation. Spa will be 550 gallons in-ground plaster/concrete. Natural gas-240VAC. No jets. Does heater sense pressure and temperature? What pump should I get to match with this heater?

A  Answered on 5/4/2015 by InyoPools Product Specialist Patrick P.

This heater does have a water pressure switch and has a thermostat, so it does sense both water flow and temperature. Since your house is at 5,600 you would need a Raypak High Elevation Heater. The 206,000 BTU Raypak heater has a minimum flow rating of 20 Gallons Per Minute (GPM) and a max flow rating of 120 GPM's. Based on these flow ratings any pump from 1/2 HP to 2 HP would work fine with this heater.

What is the difference between an Electronic and Millivolt ignition?

A  Answered on 10/10/2012 by InyoPools Product Specialist Patrick P.

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?

A  Answered on 1/16/2012 by InyoPools Product Specialist Patrick P.

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.

21 year old heater didn't work and needed to be replaced

Written on 5/20/2020 by David E.

I removed old heater. I set the new one in its place. I piped up the gas line first because that is the hardest to do. I piped up the line from the filter to the heater then the return line back to the pool. Everything went well.
