I have a cold room under my new front porch. its awful cold up here but in the summers the cold room is not so cold. I was pondering installing an evap and condensing unit in this space as it is fully insulated i thought would be pretty sweet to have in house. As well I have a permanent draft tap planned on the exterior wall which should be a hit. I also considered water cooled to preheat my domestic hot water. Floor drain is key too. Im sure at some point in my life a deer will hang in there as well. Any input would be appreciated and I will post pics as it happens. Cheers have a good one.
