Thoughts on the Grundfos Comfort System
Just wondering what your thoughts are on this system, specifically when a third line for recirc is NOT used and the under sink thermostatic valve is used instead.
We had a call back today for "no cold water", myself (apprentice), and the plumber I was with that day put in a comfort system along with a water heater and tank booster a few days ago.
After doing some more research about these valves, they are normally open until the temp in the hot line reaches 95 degrees, and cold line is going to be similar. So where is the up-side to this setup?
If the circ pump is on all the time, depending on where the cold supply comes into the house of course, you could be waiting a while for cold water.......
If the pump is on a timer, you will have both problems, waiting for hot when the pump is off, and waiting for cold when the pump is on........
Am I missing something, I don't see the value?
