Yes. I estimated that if the fluid was entirely water, that plus a flow meter reading three times too high would reduce the COP to 1. The flow meter pipe was reportedly about half full of water, and the flow meter was the wrong kind, so an error on this scale is plausible. I do not mean I am sure this is what happened. Some other combination of errors might explain it. Perhaps it was a mixture of steam and water, and perhaps the flow meter was off by a factor of 6. Or, perhaps there were problems with the thermometers. I think there may have been. I think in any scenario, wet steam is likely to be the biggest contribution to the error. - Jed
