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

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 the SR 333NA and the HD model? What advantages or disadvantages does the cupric nickel provide?
 Reply

A  Answered on 5/5/2016 by InyoPools Product Specialist Charlie R.

The only difference between the two is the SR333HD is rated as a Heavy Duty heater with a cupro-nickel heat exchanger that stands up to the harshest of applications like low pH, high flow, or heavy use.

Will this heater work with a 3 hp pool pump and a aqualink rs6 control system
 Reply

A  Answered on 6/30/2016 by InyoPools Product Specialist Lennox H.

Hi Jerry, A 3 HP pump can be used with this heater if the flow rate does not exceed 120 gpm, if it does you will need to install a manual bypass. It can also be wired to a Jandy Aqualink RS system.
