Heat Exchangers Copper vs. Stainless SteelAccuServ

Many HVAC appliances have a component that is known as a "heat exchanger." They come in many forms but it is the metal that composes your heat exchanger that often makes one of the biggest impacts. What this piece of metal does is transfer heat from one fluid (e.g. hot water in your water heater) to another (e.g. domestic water running to your tap).
