Return type. In computer programming, the return type (or result type) defines and constrains the data type of the value returned from a subroutine or method.[1] In many programming languages (especially statically-typed programming languages such as C, C++, Java) the return type must be explicitly specified when declaring a function.

Older furnaces that were made with heavy metal heat exchangers, like cast iron, have been known to last 30 to 40 years, but they're also known for being energy drainers. Forced air furnace heat exchangers have an average life expectancy of 15 years, with a range typically between 13 and 20 years. Most heat exchangers used in models today today will last between 15 and 25 years and are usually made from aluminized or stainless steel. It's inevitable that the constant heating and cooling of a heat exchanger's metal will eventually cause it to crack, become corroded or otherwise fail.
