re: Heating and cooling - mini split

I only turn my shop minisplit on when I am planning to head out to my only partially insulated shop.  Even on the hottest days, it only take about 15 minutes to get it comfortable enough to work and since it blows right at my workbench, I rarely wait that long to get started.  In fact, more often than not, I turn it on when I go out and just turn on a fan (in the summer) to take the edge off until the MS gets the shop down to temperature.   It is slightly different in the Winter when I am heating the shop but I just wear a sweatshirt or something until the shop is to a comfortable temperature.  It takes a little longer it seems in the winter but it also usually has further to go to get it up to temperature.  One thing to watch out for in the winter is managing condensation.  Concrete slabs and cast iron tools wills sometimes show a little condensation between between heated and unheated times.  If you find that you have a wet slab or condensation forming, you may decide you want to set the heat in the shop to the lowest setting.  This will make warming it up during the coldest days quicker too.
