To heat the soil blocks and plants in my large double poly greenhouse (3000 sq) , I am thinking of hooking up an on demand propane fired Bosch water heater to some pex tubing and running it on 9" spacing looped under my benches.

Anybody else try this?

Thanks J

What is the heating system for this greenhouse?
 
 Huge reading with a google search "greenhouse under-bench heat".
 
Consider puting in a back flow preventer and a boiler feed which would reduce water presure to 10 lbs;
then run the system with a high % of  pink RV anti freeze.
 
My experience is that if  I was  not planning to run water temps over 150F it would be cost effective to use
common black plastic water pipe in stead of pex.
 
Before going with all that pex compare the price of a couple runs of 3/4" copper fin pipe (the tubing with
aluminum fins that in the houshold HWBB.)
