By today's standards, a monster, wasting about 99% of the energy in its coal fire. There was luck involved - steam melted some solder that was used to seal the chamber allowing water to rush in and condense the steam, dropping pressure and now allowing the atmosphere to push the piston and thereby do work lifting a load - how early engines worked. It was the immortal James Watt who realized you could boost efficiency by using a different chamber to do the condensation and thereby keep the primary chamber hot.
