Residential and light commercial boilers are all I do, and that includes radiant floors.

Installation cost is higher, operation cost is much lower. Comfort is the best. Once you have it in your garage, you will never be happy with forced air heating again.

You MUST put 2" of insulation under the floor and around the edges.

I live in Chicago, but I also do work in Northern Indiana, SW Michigan and SE Wisconsin.

Radiant floors, when properly designed will keep the space comfortable even though you may open and close the garage doors often.

Send me a PM and we can go from there.
