That's Ok xcrispi. I was remembering things Zandor had told me in threads way back. Yes friends had monster tanks and no real regulator.

What do you control burners with ? One of my bro's want to since he has natural gas and the burners already. How do you keep rez temps down in the heat? Chillers or rez in another A/C room to circulate ?

I don't know everything but I can find almost anything out here. Glad to be straightened out. Thanks.
