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.

I'll share one question I have. Could a grower install a hydronic heating
system in the floor of a tunnel? A hydronic system forces heated water
through a tubing system buried in the floor, heating the floor. The heat
rises from the floor, heating the whole tunnel but focusing it on the root
system first. The system could be heated with a hotwater heater, driven by a
small pump. It could even be prewarmed with passive solar heat. Anyone tried
this idea?
