There are pricey temp adjust controls available today, you set the temp
with a LED readout and it stays there forever provided theres enough
hot water.

I was told there about a 1000 bucks, costly but how often o you replace
a shower faucet? with the temp preset how much water / sewer/ heating
water energy will you save in a lifetime?


The temp presets are there for safety, not to save money on heating water.
