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.

I'm at 8200' elevation.. I have a 300 sq ft hot tub. I want a 104 degree max heat. Which heater should I buy

Hey Cynthia, yes if you are looking for a heater that would work at max 104 for a spa, then the MasterTemp Heater 300,000 BTU - LP w/ Electric Ignition Low NOx - 460735 would be right. Keep this in mind BTU ratings would not only be affected by the body of water but also the gas line running to the unit. If you are replacing a similar sized BTU rated heater your good to go, increasing or decrease we recommend checking with your installer to make sure.
