EuroFresh Farms – Another example of using water as the heating medium

Here’s another example of a greenhouse, this time a huge commercial greenhouse, that uses water as the heating medium.

There are substantial differences between a geothermal water system and this system, namely, the temperature of water they use is very hot relative to a geothermal application and therefore they do not use the system to heat the growing medium directly.

They also use natural gas to heat the water.  Natural gas is good because it burns into primarily water vapor and CO2 which they recycle by giving it to plants.
