Okay, here are the specs for these boilers: file:///home/chronos/u-1160197d37ec1500e70f021620dd3bae3f09f41c/Downloads/DR_Electric%20Steam%20Boiler_Nov10.pdf
The models S242 and CR242 are both 420 kW. The dimensions for both are listed in inches: 43" L x 58" W x 78" H That's 1 m x 1.5 m x 2 m I think you could fit two of these in the shipping container. However, if you fired them both up, the heat would be intolerable. I expect the heat transfer efficiency of these units is better than the small square boxes in Rossi's device, so there would be less waste heat. - Jed
