Alright I think I've figured it out.... Normal hot water tank, thermo siphon supply into the top of the tank with the return from my floor Y'ed Into it. Return going back to the stove exiting from the drain at the bottom of the hw heater with the suppy to the floor T'ed off somewhere in this area along with the circ pump. If it was designed correct I think it would work well and the suction from the circ would encourage the flow of natural convection. Thoughts?Comment

When you have multiple loops with Y-connections, there is a possibility of water flowing in the opposite direction, without any check-valves.

Originally posted by organic farmer View PostMy system has been in operation for a few years. The pressure reliefs lift a few times every year. No problem so far.
If it is a low pressure system and you can use a vent pipe it would be great.[SIGPIC][/SIGPIC]Comment

When I was a kid we made and placed a copper coil inside the fire box of our wood stove, it pumped water through the coil and into pex tubing in our concrete floor. Even in the teens weather we could burn for four hours in the evening and sleep warm all night. home was earthen berm, super insulated.4X Suniva 250 watt, 8X t-105, OB Fx80, dc4812vrfComment

A copper coil in a wood stove is a time bomb, copper will work harden in the heat, and will fracture easily. Stainless Steel is the preferred material for a heat loop in a stove or heater.
