To do so would require special (or ancient) "load centers" (breaker or
fuse panels) than the standard -- the current 'standard' panels,
meters, etc all *assume* 120/240v single-phase power.
Also, there are ways of freeing up space in typical panels to make
room for a required 240v circuit -- skinny half-wide breakers can be
used to free up a double-pole hole.
OTOH, running a 345.6 KWh-a-day device on residential service at
PSNH's rates would quickly bankrupt me...
