Closed loop questions

[thhardin]

My wife purchased a sequense 3200seq21 for me for X-mas to serve as a pump for the two sea-swirls she also bought me for a closed loop system. I wanted a large sequense pump in order to be able to replace my main circulation pump 3500Seq21 in case it failed.

I am curious if I could somehow plump an in-line Fireplug heater into the Closed loop system for the sea-swirls. The problem I see is that the flow through the heater should be no more than 400 gph. I expect the closed loop to circulate much more than this. Any way to plumb it into the closed system?

Perhaps you could create a 3rd output, and put a gate valve on it....??

It won't be flowing through the swirls, but it works.

First let me say what a wonderful wife you have, second, I agree with Peej's idea. You could drill a new hole in your tank for the heater outlet.

You dont even need a new hole...Although it would look better.

The pump and heater will be in my basement. I do not want the additional plumbing upstairs at the tank. I was thinking I could run some sort of "crossover" a few feet from the pump output with a gate valve, then back into the return line. If I did this, I am unsure how I would be able to determine my flow through the heater. The heater requires 200 to 400 GPH to operate properly.

And yes, she is a wonderful wife!

I was going to suggest this, but I am unsure to how the plumbing would react with the high pressure flowing past the heater return. Seems like it would have some sort of venturi/sucking effect.

Do you think putting the gate valve after the heater would work?
