Does anybody have a comment on this? Our builder didn't install the two water controllers he quoted for with the Rinnai Infinity Enviro 26 because he now says:
"It is a requirement by law to have the water temperature limited to 50 degrees for safety reasons. Hence the installation of water controllers would not be of any help in order to achieve a higher water temperature."
I know that tempering valves to keep the temperature to 50 degrees are now standard in new builds but can't you have untempered water to the kitchen and laundry?
And, if what he is saying is true, why do Rinnai sell water controllers?
