You might look into purchasing a hot water pressure washer.  We use
these often in NYC for removal of previous wax coating on bronzes.
If you remove the constrictor nozzles on the wands (which produce
the narrow pressurized spray) you can also use them as sources of
warm water.  The higher volume of water that will flow through the
pumps without the constriction of the nozzle will reduce the amount
of time that the water is exposed to heat within the coils and lower
its temperature below the rated values.  You have to be attentive to
the machine when not in use as the water can overheat between
applications but with management it is feasible.
