Congratulations on the garage.The only thing better than a garage is a heated garage. The garden hose type set up is radiant heat. It's also a wonderful thing..no more cold feet or knees....wonderful. Some drawbacks, it won't heat the space quickly, if you don't already have baseboard hot water heat in your house to tap into, you will be adding another system weather it be oil, gas, or electric its another bill. It depends on climate zone , type and R values of your insulation (foam seals better than fiberglass) blah blah Yeah I know, Congratulations!
