I salvaged a nice heater off a renovation job. Its a 10kw - 208v 3phase heater. I was going to just sell it, but thought i'd do a little research and see if I could make it work for my garage at home. So obviously I need to convert from 120/240V 1PHASE to 208 3PHASE.
Does anyone know the best way to accomplish this? The heater is the only thing I would be running. With a heater do I still need to calculate horse power? If so we're talking around 13.4 HP and an expensive rotary phase converter,right?

A static 1 to 3 inverter (a UPS without the batteries) would also do the job.
You'd be better off buying a new heater or several.

Thanks heres the nameplate info:
Electromode model: CI-10-A
volts= 208 phase = 3
cycle = 60 kw = 10
amps = 27.8
 
Don't bother with a rotary converter. Look at the schematic, and see if there is some way that you can connect _part_ of the heater as a 240V load. You might not be able to get the full 10KW out of it, but you may be able to use the heater.

Does it include a 3 phase fan motor?

If you could get the wiring diagram for the inside, you might be able to just reconfigure the heating elements for 1 phase. Heating elements are just resistors. The current would go up by the square root of 3 however, so 48A, for which you will need a 60A circuit. But you will have that situation anyway.
 
The heater may comprise three 120 volt elements connected wye. If so, they may be able to be directly connected to a single phase 120V source. If he's lucky, there are two elements per phase and they can be put in series and connected to 240V.
 
I checked inside the wiring compartment and inside the heater itself, no wiring diagram.
I can tell you this though. The thermostats are labeled 120V/35A - 230V/28A and the fans are labeled 230V-55W-1PH-.3A. 2 feeds coming from the wiring compartment go to the thermostat and the other feed goes to the heating coil.(There are actually 6 wires coming from the wiring compartment because this is a two-in-one type heater as you can see by the photos.)Each side has its own thermostat.The fan is wired to the heater and the thermostat.
There are several wires connected between the heater coils, maybe the photos will help.
