These are the manufacturer's published terms. Terms can depend on the installer, the dealer program and where the heater was bought, and they change without notice, so we confirm the exact term for your install on the written quote.
The traditional material and the cheapest to build. It transfers heat well and does fine on well-balanced chlorine water, but it's the least forgiving of low pH, high chlorine and salt. Water chemistry has to stay in range for a copper exchanger to reach its full life.
See every material side by side on the comparison page, or read the Raypak fault codes guide for what the display is telling you.
Most to least forgiving of salt and unbalanced water.
