Which is better, digital or millivolt ignition? Why?

I have an older RayPak natural gas heater model P-R335A-MN, 334,000 BTU, which has been deemed no longer operable. I have a 30' round pool, 25,000 gallons. I would like to replace my broken heater with a similar model, the Raypak RP2100 Heater 336,000 BTU NG MV - PR336AMN, #009194. Would this new model be a simple "plug and play" type installation for me?


A  Answered on 6/8/2019 by InyoPools Product Specialist Lennox H.

Hi, Kevin. This RP2100 Heater 336,000 BTU NG MV - 009194 will be a drop-in replacement.

Can I use on above ground pool? I have a 15-30 oval. I want to have a bigger heater than required so I can heat faster

A  Answered on 3/30/2019 by InyoPools Product Specialist Lennox H.

Hi, Rob. This size unit is larger than what is required for your pool providing a faster temperature increase. Some states prohibits the installation of millivolt units.

We currently have a RayPaK 266000 btu ng heater. It lasted 10 Years, any value to upgrading to a 336000+ heater? The pool is 18 x 38 and averages 6 ft deep. We are in wisconsin.

A  Answered on 4/10/2018 by InyoPools Product Specialist Joe S.

The larger the unit the faster the pool will heat.Since the unit is larger and able to heat faster it will turn off quicker. As far as up sizing you would have to review the gas line sizes you currently and see if they will match the specs to the 366k.

Does this unit have electronic ignition?

A  Answered on 1/22/2018 by InyoPools Product Specialist Lennox H.

Hi, Skip. This specific unit is not equipped with an electronic ignition system. The Raypak Heater 336000 BTU NG ELE - PR336AEN / 009218 is the model with the electronic ignition system.

I have a Raypak 336 heater. Can I use it for salt water pool/

A  Answered on 5/12/2016 by InyoPools Product Specialist Matt S.

To know for sure, we would need to know the full model number of your specific heater. This heater is a standard copper heater exchanger which is not compatible with saltwater pools. Only heaters with Cupro-nickel heat exchangers are suitable for saltwater. Check your heater's model number if it ends with a "C" it is copper, if it is an "X" then it is Cupro-nickel. For example, PR366AENC or PR336AENX

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.
