I'm trying to save LuJon from a "hijack" charge. This may not belong in this forum but the idea came from the trailer build thread....soo..
I have a dedicated boiler in my shop (36'x60') in Idaho and a water heater for the shop bathroom. The cost has run about $100 per month in propane for the 8 months a year I run it. It is a 3 zone and I just run the two outside zones and not the center zone. I keep the shop at 60 degrees which is just about right for tee shirt working. I do wish my reloading room was a little warmer because it tends to be a place where I sit and don't really move about much. I think an electric heater will solve that problem. NOt sure why the picture is laying down.
Second shot is the reloading room under construction. Hydronic system is between the reloading room on the left and the bathroom on the right.
If you are building a shop from scratch or a house for that matter hydronics is certainly a wonderful way to heat. My house also has hydronic heat and I wouldn't go any other way.
