Sandblast has it rite as far as I am concerned. I have installed radiant heating in several slabs you can’t beat it. We did my sons 42’ x 64’ shop for his construction and landscape business. The building has a 16’ high ceiling but it is always warm at floor level. The thermostat is kept at 50 degrees if you set it any higher the guys start whining because it is to hot to work. I don’t know how big your shop will be but if it is say 24×24 you would only need around 600’ feet of 1/2” pex pipe hooked to a on demand gas water heater to do the job. If you have the talent to do it your self the installation is not that expensive. Off the top of my head I would say $1000 for the heater, $300 for the pipe, relay, thermostat, circulator, misc pipe and fittings $500. So for around $2000 you have a top notch heating system. I got 1/2 that much in a hanging modine type gas heater it works fine but I must still wear warm footwear on my cold wooden floor, with radiant floor heat I could go bare foot as long as I kept a tight grip on my tools :-)
