i will be helping a friend install a HW toekick heater in a kitchen remodel. should venturi tees be used as part of the install? the house has 3/4" copperfinned baseboard and the kicker has 1/2" copper tubing. the manufacturer instructs that a regular 3/4x1/2x3/4 tee be used to supply water to teh kicker. the water leaving the kicker should be reintroduced into the 3/4 copper via a 3/4x1/2x3/4 venturi tee. their position is that the venturi tee is on the return line as its purpose is to create enough back pressure to onduce water to enter the kicker via the regular 3/4x1/2x3/4 tee. any thoughts on this?
