Flow in a Twin-Flo hydronic kickspace heater

Marty Yandle

I have single loop baseboard heat & am adding Beacon/Morris kickspace heater in kitchen where there's no heat. After revisiting Dan H's paperbacks I'm wondering, What will make the water flow through the unit?! It is 10" between the in & out, I'm plumbing it straight up off the primary 3/4" line with 1/2" into the unit. Won't the water just shoot through the bypass? Do I need a monoflo tee? I guess I'll find out... Email if u have a quick answer.

monoflo tee

Thanks, Kevin. Why on the return, unless backwards? Don't I want to divert into inlet? Or why not both? (Directions do say "flow or balancing tees"- I hadn't noticed) I can also chat w my plumbing supply. Is this a 'stock' item? Marty

Dan's words are great!


Q: If the cone is on the return side, how can it divert the water up into the radiator?


A: You'll have to use your imagination to see what's going on here. Think of yourself as the water. You're flowing down the main toward the set of tees leading into the radiator. The first is a standard tee, the second, a diverter tee. You look up ahead and see a bottleneck on the main "road." That's the "traffic jam" the cone is causing. Things are slowing down so you decide to take the "service road" through the branch.

Once they're past the cone, the two flows - one from the main and the other from the branch - join again and continue to the next set of tees. Get it?



Q: So the diverter tee's not "scooping" the water up into the radiator, is it?

A: No, it's just creating resistance along the main. The water follows the path of least resistance through the branch.
