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.

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.

How do I know if it is cupro-nickel? The only difference I've seen is in the title. The product descriptions are the same between this heater and the #010132

A  Answered on 3/21/2017 by InyoPools Product Specialist Andy O.

Hello Kristen- There are two places you would see the differences the first would be in the product name where it lists it as a cupro-nickel and the other would be in the model number which ends in an "x" which is the designation for the cupro-nickel models.
