Are you using this to heat or just filter? I'm more worried about proper circulation and ability to heat.

This is a new-to-me spa that I already fixed. This will be the first I have used it. I own the gas well and it has far too much pressure on it. So the more I burn off the better. I hate to pay for something that I have sitting there for free so I'm pretty reluctant on the electricity avenue.

I hate to beat a dead horse, but what are your thoughts on using a dedicated hot water tank as the heat source? If I have it set at the desired temp and the always on circ pump running, would that work?

Not the news I wanted to hear, but thank you, guys, for your feedback! If I stick with the electric heater in the spa, is it cheaper to run it at the temp we want all year, or better to let it cool down 10 or so degrees when not in use?

Spa only for now. I'm in pa where it gets cold and I want to run it all year. I'm $1600 on the raypak. Already ordered. I just found this forum today and info had been sparse

So it looks like when the control needs heat, it just pushes 220v power to the electric heater. Would I be able to put a relay (or something) in line that would sense the 220v and close the circuit to turn on the raypak? I guess I'm not following how it would work if the control calls for heat and the raypak says it's still good. Or worse, the raypak thinks it needs to turn on but the spa doesn't so the spa pump never kicks on and the heat is running.

How do I prevent the spa from freezing in the winter? Leave the circ pump on at all times?

I recently acquired a Caldera Salina Spa with Electric Heat. I have free gas and would like to convert it over to the Raypak 156a. It already has the remote control option built into it. My question is, how do I send the on/off signal from the current Caldera topside board to the new Raypak Heater when it demands heat? Currently, I believe when the board demands heat it just turns the 240v elec heater on that directly wired to the board.
