What is the difference between an Electronic and Millivolt ignition?

Inyo Answer

Answered on 10/10/2012 by 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.

I would like to replace my current heater with this unit. It is supplied with propane but I will have Nat Gas next year. What is the parts cost to convert? Also, this will replace a Ray Pak P-R405A. Is the wiring basically the same?

Inyo Answer

Answered on 05/26/2012 by Product Specialist Patrick P.

The Conversion kit for the 406 unit is only available for the milivolt unit and not the electronic ignition unit, you may view the conversion kit here http://www.inyopools.com/pool_parts_raypak_atmospheric_heaters.aspx (last part on the page - $125.99) This link has an explanation on the differences of electronic ignition and milivolt ignition http://www.inyopools.com/poolanswers_heaters.aspx#electonic_millivolt_ignition and if you would like to purchase the entire heater you may do so here http://www.inyopools.com/heaters_rpseries.aspx Yes this would replace the P-R405A and if you went with the electronic ignition version the wiring would be relatively the same, however if you went with the milivolt ignition there would be not wiring involved.

Will a gas heater operate at the low speed of a dual speed motor?

Inyo Answer

Answered on 01/16/2012 by 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.

Pros: Works as advertized

Cons: A little large and heavy

Had my last Raypak for over 20 years with no trouble. Of course I stayed with Raypak. Instalation was easy thanks to the unuions on the standard model.
