Pvc pipe on hot water heating systems?

Answers:
Wow I can't believe some of the answers that you have gotten here.They are correct that you should not use PVC pipe it can't handle the heat and I have never seen CPVC used in heating lines,some might say it is ok but I would never use it.Type L copper is generally used for potable water lines and type M is used for heating systems,{ yes type M is thinner walled but the finned tubing is even thinner and a heating system should never get above 30 psi.unlike potable water systems that could have up to 90 psi.] I am not aware of codes that require black iron pipes for heating,sometimes it is used at the boiler for the manifolds but gets quite pricey for the whole system.With that said copper is getting too expensive to do a large system with these days and plastic PEX type tubing is being used all over now and it has a proven track record.However it is a special pipe used for heating,it should be marked for heating systems and not for potable water.Some will be marked Heatpex,Hepex,Hpex.Other companies are now making this type tubing and may have other markings and there is one brand that has a thin layer of Aluminum inside.This tubing when bent will hold the shape that it is bent to.The main difference between regular PEX tubing and a heat PEX is the heat PEX will have an Oxygen barrier in it.The new in floor radiant heating systems use mainly heating PEX tubings both in concrete floors and under regular floors,some of these systems have thousands of feet of tubing if these had to be done in copper or black iron no one could afford to put it in.I would use both copper and heating PEX tubings.Copper at the boiler and some at the base boards and PEX in between.
No definately not. Copper pipe is the way to go. Copper fin tube is used to omit the heat out into your living quarters. All the pipes coming from the boiler should be copper TYPE L.
Yes but use cpvc. Inquire at a quality hardware or plumbing store they can help you. Cpvc is heat rated higher than regular pvc pipe.
Solid black pipe on hot water heating systems, and if you
don't know why, you better, CALL YOUR PLUMBER.
City Ordinance. <l:-})-[*
tou can use pex tubing or copper,and black no pvc
No pvc. Go with copper. It will be easier to fix a leak, or replace in the future then black pipe. Copper is good for almost any application except steam.
PVC isn't rated for hot water. CPVC is, but it needs to be insulated. PEX pipe is also used in heating, and again, it should be insulated. Copper is the best pipe to use, but nowadays, the cost is prohibitive. Good luck!
PVC pipe will heat, expand and eventually burst. You should use CPVC, pex, or copper. All water lines should be insulated. The pex is the easiest, CPVC is the cheapest but still good, and copper is the best but pretty costly. good luck
No! Do not use any plastic pipe.
Use copper or screw pipe.
The most common pipe used is Vanguard Pex Pipe.
Black iron is very common but the old school way and not used except in commercial, government or industrial buildings.
Copper is very good, but presently is priced out of market for most comsumers.
