Type of piping for pool heater

karenn

I am about to get a 3/4" gas pipe installed for a pool heater. I am trying to figure out what type of piping I should get installed. Does the CSST piping make noise when the gas is on for the pool heater? (it will be installed in my attic space). Should I go with CSST and galvanized/black or should I go with Galvanized only?

I do not believe CSST makes noise but pretty much everyone on this forum will tell you to use black iron pipe.

I would second the black threaded pipe.

Your installer has determined you need only 3/4" supply?

Heater in the attic.......never heard of that one.....but then I am just a country boy.

The heater is not in the attic, but the piping will be installed in the attic.

I guess i will go with Black iron. Not sure if I am convinced yet.

CCST is glorified appliance connector. We cannot legally run an appliance connector in a concealed space due to its paper thin wall construction. Yet.....CCST can be run pretty much everywhere.  I would only run black pipe in my own home, or copper/black if we are talking propane.

CSST has a tendency to get holes burned in it and start a fire with nearby lightning strikes.

There are less safe ways to move natural gas than CSST. Black pipe is preferred. https://www.dailymail.co.uk/news/article-2108346/Chinese-villagers-carry-giant-balloons-stolen-natural-gas-heat-homes.html

I agree that CSST is junk. I have used it only a couple of times. Temporary feed to a couple of roof top units, above a drop ceiling with 2' square tiles almost touching the joists. Couldn't get a 10 footer in there no way and the CSST was protected.

Check the size of your pool heater they are usually 250,000-300,000 btu. More like 1" or 1 1/4" pipe

Thank you all. I am convinced. I will go with black pipe

Your pool heater must be VERY small. You can't get much gas out of a 3/4" pipe. What is the input rating of the heater?

JUGHNE

Maybe with a short run with 2 PSI system?

Or propane
