Heating a lower level garage. Radiant or not?
I am adding an addition to our house which will have a walk out garage. I will be using the garage as a shop mostly. Being that the garage is not really exposed, except maybe 4-6 ft, how cold will the floor get. I live in WI, and a buddy of mine says his garage is 40-50 during winter. I plan on insulating the poured frost walls and the foundation walls with R-10, and the 2x4 walls with R-15. Would insulating under the slab help with retaining the heat in the slab. I almost think leaving the slab un-insulated would let the ground "heat" into the slab, providing the rest of the slab and walls are insulated. I am using a mod con boiler for the living space above with a thin slab pex application, and possibly using staple up for the existing house. The floor will be insulated from below min R-30. I just want any thoughts and ideas on the best way to heat this space. The thermal mass that I would have to keep heated might not be the best idea in my case. The time needed to bring it up to temp would be significant. A gas modine heater is an option or a 80% horizontal flow would give me a A/C option in the future, but to stay on topic, since this is the radiant section. How cold will a 42x 30 x 9 ft garage really get, I know you need a heat loss calculation, but how about a general idea, is radiant the way to go? Cost isn't really a factor to some extent. Ideas, opinions, advice?? Thanks in advance. Awsome Site!!!
