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.
What is the Conversion from natural to propane?
I am trying to hook the Max-E-Therm heater to a Jandy Aqualink controler. Need to know how to wire. Do I use 3 or 4 wire connection?
I have ne of these for ten years and the exchanger is cracked well after ten years thats fine and I am sure it was a free at some point for this issue. Anyway, I want to purchase from your site as price is same everywhere join internet at $1999 but a local outfit out hear wants 3,250, are you kidding. I should be able to swap out the unit. And that is my question can you recommend an outfit out hear or is it simple. now mind ya I am quite capable and have hooked gas lines before, send email.
Hello Richard, We would recommend that the Max-E-Therm Heater 400000 BTU be installed by a licensed service technician. In the event you need to utilize the 1 year manufacturer's warranty, they may require receipt information of who it was installed by. We suggest you contact a local pool part/supply company that performs installations.
(3 out of 5 stars) Good heater, BUT...

I purchased this heater from Inyopools approximately 5 years ago. It has been great, but I learned something this spring, do not buy this version, only purchase the Cupro Nickel version. The heat exchanger in this model is not long lasting. I just replaced this heater with a Raypak Professional B-R408A-EN-X.

this is my third pool heater and my last. Small and powerful, this heater is fantastic. all external parts are plastic covered, so it can't rust. It heats the spa in about 10 minutes to 90 degrees. I love it.
