Question What are people using to heat their greenhouse with?

I'm in Michigan and I'm new to greenhouse growing. I'd like to know what others are using to heat their greenhouse with. I thought about a vent-free blue flame propane heater with a built in thermostat. I'm more likely to need heat during the early spring than I am through harvest this fall. I already have ventilation hooked into a temperature controller but I still a source of heat. What are people using to heat their greenhouse with?

A propane heater would definitely be the way to go. Plus you could utilize the benefits of the added Co2.
