I am installing a Buderus radiant panel in a finished room in the basement. Looking for the most efficient way of doing so. The heat guru at a local supply house told me to tee off the supply to feed the radiator and then tee into the return (2 pipe system). Another option is a single pipe system, either in the supply or return line I could tee off to feed the radiator then return out of the radiator back to the same line. I was told to add a ball valve between the tee's to throttle back flow and force water through radiator. These tee's will be coming off a 1 inch pex loop from a new OWB 100 ft. away with a taco 009 pushing the water. If anyone has a similar setup please comment I don't want to do the install and find out I won't be getting proper flow. Thanks Doug

The tees and valve will certainly work, but give you no thermostat control.  Did you want that?

The radiator has a thermostatic head on it that controls the flow of water. That's the beauty of these radiators, I dont need a seperate pump, thermostat, and controls. So you think the single pipe setup will work? Have you used this setup? Which line would you use?

If that is the case and it simply controls the flow, and doesn't shunt the water around itself, then you do not want to put a valve in the main line as this will simply restrict the entire main line when the radiator is off.  You can try a simple TEE, putting the radiator on the straight through path and hope you get enough flow.  Not sure what else to do other than maybe a pump.  You would have to control it with the radiator some how though.

I like the idea of feeding the radiator straight through the run of a tee on the supply. I am bringing 1 inch pex into the house when I get to my mech. room I will add a 1 inch tee, the branch will feed my indoor boiler. Coming off the run of the tee I will reduce to 1/2 inch add a ball valve and feed the radiator. Water, pumped or gravity fed will take the path of least resistance. The radiator will take what little water it uses through a 1/2 inch line and the indoor boiler will get all the rest. Does this sound like it will work? Any comments welcome.

I am going to look this rad. Up sounds like a good fit for my garage

Sounds good.  Let us know how it turns out.

Update:  I have my owb piped and it has been running for a week now. I ended up piping the radiant panel with a venturi on the supply and another on the return. It works great! Now I just need some cold weather to put everything to the test.
