Hi All, I'm just finishing up my coop as winter is setting in here in Minnesota and am to the point where I need to decide which heat source to use. It will either be the 24" square flat panel eco heater that a few of you are using, or an in floor electric radiant heat system. My coop is 3' wide x 5.5' long x 4' tall (interior space), fully insulated, and built with standard 2x4 framing, and it's built inside the back of my garage. The eco heater would be easier to install, but if the radiant in floor heat would heat that space I could use sand in the coop instead of wood chips which seems like it would be much easier to maintain. Does anyone have any experience with a radiant floor system? Would it heat up a few inches of sand and in turn heat the coop? Also, can I hook one of these up to a baseboard heater 120v thermostat (I know they make special t-stats for these with timers and floor temp probes but i just need regular t-stat function) It gets really cold here (-20 easily) so I think the sand would be too cold unless it was actually heated, but I want the coop to stay warm enough to keep my girls warm and safe and the eggs from freezing. Thanks!
