[GBlist] Solar Hot Water Heating - Slab on Grade



 
If anyone can tell me where to learn how to post I would greatly appreciate it. 
 
Also I'm looking for info on solar hot water heating of a slab.
 
I have two thermodynamic panels at 4' x 8' and wondering if there is any use on attaching to these to my slab to help heat or pre-heat the hot water for my radiant floor  4" slab on grade.  Some people feel that there is no appreciable energy savings and that it is a waste of time and money.  My heater is an propane fueled on demand hot water system that heats both potable and slab water.  Two loops. 
 
My location is Ottawa, ON Canada - similar latitude as that of Minneapolis MN - and same weather pattern as Burlington VT - at least it seems that way anyway.
 
We are thinking of doing the solar hot water heater as a drain back system.
 
Any resources and thoughts - greatly appreciated.
 
Thanks.
