[greenbullitt]

dont know if it would suit your purpose... but you know the electric heaters they have checkout of home depot and stuff... i am about to demo a building that has those and i think there may be 5 or 6 of them.... i dont know what voltage but i can look monday....
they would be free

hell, if hes not in, I would be! pm me if so

Found this space BTU calculator. Should get you in the ball park

Forbes, if any are left, I could definitely use one as well.

any electricians here? I am considering a heater thats three phase and I am unsure whats involved in that. Shop has 220v service

[miketyler]

Ok, skip the three phase question. What about 240v? I think my voltage is 220vAC. Would a heating unit rated for 240v be compatible with my voltage source?

Its also listed as 1/3 phase so can be jumpered for single phase.

Yes and Yes if it's designed to run on single phase or 3 phase. You have it backwards your power is most likely 240V and the heater is rated for 220V


Most motors are rated at 220 Volts that way they can run on 120/208 WYE systems and 120/240 delta systems.

I settled on a Fahrenheat 7.5kw 220v unit. I want to ceiling mount this and will probably be located about 20-30 ft from the box. Specs show if configured for max heat will pull 31.3 amps. Any recommendations on what size cabling and how to run this for code compliance?

I just purchased a kerosene heater for my shop 26x30 over one of these electric heaters. You can buy kerosene in bulk for a lot cheaper than you can get the stuff at lowes or home depot. Used heater last night, was amazing in an uninsulated shop. Is a 26k BTU heater.

[ceyko]

Only problem I have with kerosene is it tends to be smelly.

[zachary]

Yea i had read about that, apparently if it is all done at the right temperature there is no odor. Last night i ran it about 30 minutes and there was no odor to speak of.

[miketyler]

I have read that unburnt kerosene gases invites condensation and rust. With gas tanks, paint thinners and other chemicals in the garage I'd prefer not to have an open flame type heater.

Also, I have been using a propane heater and I dont think I get 5 hours of run time out of it. Buying and having to drive to exchange bottles, it may be more expensive but having thermostat controlled heat at the flip of a switch is a convenience I will pay for.

. Buying and having to drive to exchange bottles, it may be more expensive but having thermostat controlled heat at the flip of a switch is a convenience I will pay for.

There is definitely a convenience factor involved in the decision for sure. We literally drive right past a bulk kerosene place on our way home so that played a factor in our decision. To us it just seemed more economical versus the electric cost as much time as we spend in the garage. Hope the electric works good for you.

[miketyler]

Me too - I am unsure if I want to run the cable in the ceiling or exposed. Since there is a loft, I will only have the room access to the ceiling so will involve punching some holes in sheetrock; probably severl holes as they used the engineered floor beams. The truss style beams would have made this easier.

I suppose, if I run exposed it must be in metal conduit? Any other considerations?

[miketyler]

Also, my panel is full. I have one 220 braker for compressor and assume the heater would need to be on its own breaker. Do they make a single 220v breaker that will provide protection for two 220v lines?
