My b/o has quite a large facility, and she had several areas to heat: the original office (12x12), and the classroom on one side of the aisleway (36x12), and the handicapped accessible bathroom (12x12), which also has first aid supplies and a shower, on the other side. What was supposed to be the wash stall now serves as the grain room, but it is roughed in for hot/cold water.
The aisleway is 14’ wide poured concrete, so she had to run some of the pipes underground. She installed a regular oil-fired furnace that also provides plenty of hot water, with forced hot water baseboards. There’s plenty of insulation in the walls. The furnace room is quite toasty, and the remaining areas have the thermostat at the lowest setting, which I find quite nice when I change my clothes for work after I ride. Last winter was extremely cold and we did not have any problems with the heating system at all.
We are in southern Maine, maybe not quite so cold and snowy as Ontario. But she sure was thinking ahead with all this because it gives us access to warm-up areas when it really is cold, like in the teens. We’re talking about a 80x120 indoor with the barn attached at 40x200, and all of the heated areas are at one end of the barn. She tells me the oil bill in the summer is not that bad to keep the hot water going. I sometimes wonder if an on-demand hot water heater for the bathroom would be just as good.
