Faucet flow controls attached to the faucet allow the water heating system operate more eff ect ively. For example, 2 GPM
flow controls r ecommended for faucets, assure that t he flow rate will not e xceed 2 G PM . However, less water can always
be used. Also, consumers can mix w ith cold water as with a conventional system (See Fig. 2, pg. 3 for I nstallation).
