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

Are the Master Temp heaters okay for use with salt water pools?
Reply
Steve- For a salt water pool I highly recommend a Heavy Duty model with Cupro-Nickel. The only one they offer is Natrual Gas Max-E-Therm Heater 400000 BTU Heavy Duty w/ Cupro Nickel NG Ele. Ign. SR400HD.

Pros: NICE SIZE AND HEATER POOL QUICKLY
We are very pleased with this heater. Our pool had been down for a good month and the water temp was at about 50 degrees when we started the heater up and it heater the pool quickly. We started at the 65 degrees and back to the 82 degrees by day 2. Inyo offers great pricing and the shipping cost were reasonable and gave us the option to have a lift truck. I will not hesitate to order from Inyo Pool Products in the future.

Easy setup. Delivery flawless. Only suggestion; order Pentair mounting kit and pressure relief valve kit with the heater or you'll be trying to get them later for proper installation. Raised 800-gallon spa 30 degrees in 40min.
Response From INYOpools.com: Great recommendation and thank you for the input!

I am usually hesitant puchasing big items, like this heater, online. With inyopools everything went smooth, the packaging and delivery was professional. It has been 3 years using this heater- works great! Highly recommended.
