text: In practice, a reciprocating steam engine cycle exhausting the steam to atmosphere will typically have an efficiency (including the boiler) in the range of 1–10%, but with the addition of a condenser, Corliss valves, multiple expansion, and high steam pressure/temperature, it may be greatly improved, historically into the range of 10–20%, and very rarely slightly higher.[citation needed]
