Hello TFP,
I've used a (well used/mature) 250kbtu/hr Laars heater on our 18'x48" AGP last year. Today we just installed a new pool--a 26'x52" AGP. It's huge! My gas piping it set up to handle the 250kbtu/hr heater (1" gas piping most of the way from the meter. But per Raypak's installing specs, I would need larger piping- at least 1-1/4 for the 400kbtu/hr heater. Looking at Home Depot yesterday, the only thing larger than 1" black pipe is galvanized.
A. Is galvanized okay for low pressure natural gas service? Or do I just need to find 1-1/4 or 1-1/2 black pipe from somewhere else?
B. I talked the the gas company, and they are willing to install a larger capacity meter for free. They are asking if I want an increased meter output pressure. This I don't know--what are your thoughts and how would higher pressure impact the rest of my gas using appliances inside my home? Is there any benefit of increasing gas pressure to the pool heater?
C. With a 14k gallon pool, will I really notice that much speed difference in heating the water with a 400kbtu/hr heater vs. sticking with a 250kbtu/hr heater? I like the idea of the larger size, but I'm starting to get worn out from all this work!
D. Right now my 1" gas line for the heater T-'s into the gas line under our home that feeds multiple appliances. I'd like to have a T coming right off the meter with a dedicated line from that T going to the heater. I'm wondering if I can run this gas line externally along the side of the house to the heater? Paint it for rust prevention?
Thanks for all input!
