Numbers wise, an average large home in the North East is about 2,500 sqft, and can be heated with a 100,000 BTU Forced Hot Water Boiler with about 200 ft of baseboard.
Therefore: 200 kWh (based on an astounding 24/7 80% utilization rate for the 1 MWh unit) would provide 682,428 BTU. (1kWh = 3,412.14 BTU).
Thus: You could heat about 7 large northeastern U.S. homes.
Or: You could heat about 14 1,250 sqft northeastern U.S. homes.
Now consider that the heat source is inside a TEU, and NOT a 2,500 sqft home in below freezing winter conditions. That 160 sqft box (20 ft x 8 ft) is going to get HOT.
Now let's say that the 200kWh of heat can be wasted outside the TEU to the space; you are sourcing 7 x the heat needed to keep 2,500 sqft at room temp in below freezing exterior conditions. Rossiclown's total facility space is about 4,500 sqft according to the rental adds. This includes workfloor, offices, conference room, kitchen, etc. So it is probably fair to say that there is probably 2,500 sqft of workfloor, and the other 2,000 sqft is made up of offices, et. al. Although, even if you went with 3,000 sqft of workfloor, and 1,500 sqft other, it doesn't make much of a difference.
Lastly, let's consider that Miami is routinely in the 90 F range in the summer, and the unit was run 24/7... that is a whole lot of heat in the building, both generated internally and induced from outside.
The better question is what happened to generated heat when the "customer" process was not running? There is NO manufacturing process that runs 24/7 for 350 days straight, especially in a light industrial construct. Shifts, planned maintenance downtime, unplanned downtimes, etc.
If the "customer" process was not running, where did the 1MWh go? Where did the 3,412,141 BTU go? Where did the energy to heat 34 large Northeastern homes to room temp in below freezing conditions go? Where did it go in 95 F Miami in the summer?
1 Refrigeration Ton = 12,000 BTU/h. Where was Rossiclown's 284 Ton cooling unit to handle continuous run with no "customer" process load? You know, like a dummy load for testing?
He would need, for example, two Trane 130 Ton units (and be a little shy by about 25 Tons), which come in at around 35 ft long and 12 ft wide x 6.5 ft high, each weighing about 8 tons. Note this does not include supporting building blower and ducting needs. (For this type of loading you are probably looking at needing to move 45,000 CFM air per unit). The power needs for these units would be a 3 phase 460V 350 amp (estimated) service for the compressors, motors, supply fans, exhaust fans, and auxiliaries. It arguably would need to be around 450 amps when accounting for service factor. This works out to over 200kW just to support cooling when not running "customer" process load.
I am not buying it.
Rossi is full of shit.
