Probably not. It will all depend on the low temp you are starting from. Set the timers to come on +/- an hour before you plan to start and see if that is enough. As others have suggested, insulation is cheap and easy to install. Our 2 heaters raise the condo's 670 SQFT 15 degrees in 30 minutes. But we are starting at +/- 50 F.

I have used smaller units like this. There is no fan, open element, or ombustion, very neat and tidy
