iron to copper

C.Hall

Is there a rule of thumb to determine where to make the switch from threaded iron to sweated copper lines when piping out from a new, in my case Tarm, woodboiler? Simply cost of materials? Or some technical advantage?

Like they say with bicycle frames...

Steel is real! The threaded iron piping is better at handling the expansion/contraction cycles over the long haul. Copper can look nicer and be easier to cut and connect. The price factor depends on too many variables to say.

On some

boilers the jacketing prevents you from getting a wrench on a copper adapter right at the boiler tap. In this case a snort, or short, steel nipple with a copper FIP adapter screwed on works fine.

It's nice to se a boiler piped in all threaded black pipe. A professionally piped iron job is a sight to behold! Swing ells allow you to straighten up boiler taps that are crooked, and allows expansion movement.

Copper seems to be more common for hydronic systems, these days. A bit easier to work, in large sizes, if you don't have a pipe machine setup. Also easier to add additional tees down the road. Especially if you own a T-Drill
