Hi,

I want to install a small toekick heater in my kitchen and was wondering if I need to use a venturi T fitting where it taps into the main baseboard heating loop. My concern is that the toekick only has 1/2" piping, which seems to me like it will cause reduced flow in the main heating loop, which is 3/4", if I were to plumb it "in-line"

My understanding is that venturi-T's branch off some of the flow from the main loop, thus avoiding the restriction problem (if it even is a problem). The manufacturer says it won't be a restriction, but I'm not so sure.

Any thoughts on the relative merits of the 2 methods?

If you install it correctly, the flow diverted to the kickspace heater will be returned to the main line so the flow will not be reduced downstream.

Sme of this depends on the length of the loop but, if its a short loop you can go in and out without experiencing any flow problems. 99% of the time hydronic zones are over pumped anyway.

Hey, wait a minute.

This is awkward, but...
