Heating System with Boiler

[ridecruz88]

Hey all,
I'm currently developing a project replace a pre-existing glass greenhouse natural gas heating system with wood-fired heat. I live in Kentucky, where heated greenhouses are most necessary for any sort of germination or growth. I'm hoping switching to a local fuel source will prove more environmental as well-as cost-effective.
My plan right now is to run pex tubing under the tables from a central boiler. The greenhouse is about 30 ft. wide and 150 ft. long. Does anyone have experience installing a heat system such as this? Any recommendations for boilers?

Thanks,
Ben
