Where are you at? I have one that heats great. I bought it and have it as an emegency backup for if my Cen Heat is out.
I'd be willing to lend it to you so you may see if it is something you would want.
I also know that Harbor Tool has a great fan/heater that will heat a large garage.
Thanks for the offer, but I'm in Oklahoma. The heater I posted the information about also interests me because it has a built in air purifier. The one I'm using now if a Lasco, and it works good. The problem is it doesn't have a filter, and if you don't keep your room dust-free, the circulating dust will play havoc with your allergies.
