Which piping material uses solvent cement joints in HYDRO heating systems?

Explanation:
Solvent cement joints are used with CPVC piping because CPVC is a thermoplastic that bonds by softening with solvent-based cement, which fuses the pipe and fittings together as the cement cures. This method creates a strong, leak‑tight joint suitable for hot-water circuits found in hydro heating systems. Other materials rely on different joining methods: copper is brazed or soldered with a torch, PEX uses crimp or expansion fittings, and steel uses threaded connections or welding. So CPVC is the material that uses solvent cement joints in hydro heating systems.
