Bill, (and others).

I know of at least two growers in Wisconsin that have hydronic systems in 
their hoophouses.  One uses a wood-fired boiler (also heats home with it), 
the other an LP water heater.  I'm not sure if they also use a Modine type 
heater as well for the really cold nights...but it can be done.
