My hot water tank typically has water at 150 degrees or so, which is fine for the laundry and dishwasher, but a little toasty for the bathrooms. As luck would have it, those two zones are in different directions from the water heater, so I'm thinking of installing a tempering valve to service the bathrooms. The problem is that the cold water stored in the pipes can be up to 120 degrees, since the pipes are in an attic in Florida.
My question is -- what happens with a tempering valve like the Watts 70A or L70A if it is set to, say 110 degrees, if the incoming "hot" is 150, and the incoming "cold" is 120? I'm guessing it will flow 100% "cold" until "cold" goes below 110, and then start adding "hot" to keep the output at 110.
