I'm a big advocate of gas heating. It just makes sense in my area for me with its quickness and efficiency. With that said, I have a swim spa that I ran water pipes up through the concrete underneath (along with electric) so I could plumb into my heater and forget the electric element (or maybe use Electric element to keep it @ 60, and gas to bring it up when needed in the winter). I'd like to do it in a way that allows the hot tub to work as it should and the gas heater just circulates water to it. I was thinking 2 "T"'s with a check valve in between directly after the heating element? Heating element > Supply line > check valve > return. Any thoughts? This will have my current VS pump at the pad set to just be enough gpm to get the heater going.

Interesting idea. I wonder if a picture of where everything is and how it is set up will help us see what you are wanting to do. Feel free to do it in paint or such with your ideas drawn out.

I'm sorry Kim, we were away on vacation for the 4th and I did not see your response. I will get you pictures, but it's basically set up like a normal pool would be. Two 3 way valves at the pad, turn them one way for pool, the other for spa. Everything is ran underground. The swim spa is 14.5' x 7.5', so plenty of room underneath. I'm just not 100% on how to plumb the lines into the spa?
Here's the pad plumbing;

My spa has 2 temp sensors, J22 and J24. I'm assuming they are for redundancy. If they are, then I think I can plumb 2 "T"s under the spa with a check valve in between. The first "T" would be the supply to the heater, while the other would be the return.
The only issue that I have, is the supply line going to the heater. I don't think I would want it "pulling" water through a pump before it hit that "T" to go to the PH. Probably not a big deal when the pump in the spa is running, but if it shut off the pool pump would be pulling water through the pump under the spa, and that doesn't seem efficient. Maybe put the "T" before the pump under the spa? But that would mean that if both pumps were on, they would be "fighting" each other....
