Noritz NR71-od -ng. Incoming water psi is 65. Incoming water temp currently 81. All faucets are Moen single pull handle. Issue can be reproduced 100% at any faucet. Testing with one faucet on full hot, no issue. Temp is maintained precisely at 120 as expected. Gpm rate 2.0. Now, move the faucet handle towards the middle to get warm water. When gpm drops to about 1.2 gpm or less, temperature climbs to 130+. Once I hit 0.9gpm temp will climb even more.
Noritz had me de-scale, check the filter and adjust the manifold pressures which were a little high. Maybe this normal given 81 degree ground water and the challenge of single handle faucets messing with the flow. Advice appreciated.
