You may have seen my earlier post about repiping my shower: http://www.plumbingforums.com/forum/f9/need-advice-shower-repipe-519/
I've now got new copper pipe from under the house, plus a new Delta universal valve and fixture. The problem is that the shower is gradually getting hotter! Over the span of about 5 minutes, it keeps getting hotter and I have to turn the water colder and colder, until it gets to the point that the tankless water heater shuts down. Then I have to turn the heat back up, and the cycle starts over again.
Here's the trim / cartridge in use: Innovations Monitor® 17 Series Shower Trim : Bath Products : Delta Faucet
I contacted Delta, and they said my tankless water heater needs calibration. There really isn't any calibration on it -- it's got a digital temperature selector, that's set at 120 degrees. It's a Bosch GWH 2400 ES: Features and Specs for the Bosch GWH 2400ES Tankless Water Heater
Water pressure and flow are good, and I did make sure that the cartridge is not installed backward. Anyone have any ideas here?
thanks very much,
Mike
