How many volts?
Hi Joseoh, The Max-E-Therm Heater's w/ Electronic Ignition can be connected to 120 or 240 Volt, 60 Hz., Single Phase power.
Have a 20,000 gallon pool. Will the this heater be enough or should I get the 400,000 BTU. Don't really care if the 333,000 takes a little longer to heat up the pool
The 333,000 would be more than sufficient for a 20,000 gallon pool.
Will a gas heater operate at the low speed of a dual speed motor?
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.
Is the sta-rite heater Max E Therm low NOx rated for Texas?
Yes the Sta Rite Max E Therm heaters are LoNox rated for Texas and California.
