To conserve propane, I turn off the propane furnace in the shop when I go in at night. The little wood boiler heating the floor burns for another 4 hrs or so before the temp of the water drops and the temp sensor shuts the pump off. In the morning, I have coffee in my office in the house, do invoices, and use the wifi thermostat to turn the heat on in the shop. This morning i got a webservice error,and I had to walk out 180 feet, each way and turn the furnace on and rekindle the fire. It was minus freakin 23 this morning. Oh the humanity!!
