[Discuss] Power Cable Needed

It would help a lot to have a fan located up high next to the ceiling. Even a box/window fan up in the overhead area over the office would help destratify the thermocline that inevitably forms in spaces with high ceilings and no built-in air-movers.

I guess what I meant by "no time" was a heck of a lot faster than the radiant heaters.  The new heater should work better and a lot quicker than what we have now.  But we don't have the budget, ventilation, or natural gas plumbing for anything large enough to really heat the space.  I would prefer to have natural gas dropped in and a commercial heater installed, but that is way beyond what we can afford.  Plus, hopefully we will outgrow our  space in 3-10 months and move to a better location.

Quick calc- roughly 13,000 BTU output- is that correct? If so, and depending on what one considers "heat the space" and "no time", you may want to reset your expectations. 1000 sq ft x 10' high ceilings with avg insulation needs a bit over 62,500 BTUs to raise the temp by 10 degrees F. (I'm just guessing at the dimensions of the space).

I purchased a new heater for the space, but I need to make an adapter cable.  
Does anyone have an L6-30P connector or a cable with connector?  (Image 
Attached)  I can purchase all the parts from Jerrys, but it would be a $40 
cable.  For those of you about to ask why I don't just replace the receptical, 
the heater has a 20A connector, so I would have to downgrade the breaker to 
20A.  Doing so would limit the usabiity of the outlet, plus we would leagally 
have to hire an electrical contractor to install.

I purchased a 4000W 240V forced air
 heater.  I am hoping it will heat the space 
up in no time.
