heating room for food storage
I am going to steal space from my garage for food storage. My 3 kitchen cupboards just aren't cutting it!
We have a detached garage with a small room (7x9) that was used as a workshop. It has a door and appears to be insulated. I want to use it to store canned food and dry goods. The garage is unheated, and all I really want to do is keep this small room above freezing.
First of all-do I need to keep the temperature above freezing, or is this a figment of my imagination? If so, is there a space heater that is energy efficient and safe to use for this purpose? Any other suggestions?
