We use our propane only tankless hot water like this...
~ for showers we set thermostat to 109 (+/-) degrees and only use the hot valve on the shower. That is, no need to use the cold valve. As long as there’s constant flow, the water is hot & comfortable. We can always adjust the thermostat up or down as needed for the next time
~ for the sink...we crank the thermostat higher, even to highest setting, but only use the hot water valve on the faucet
Bottom line...it’s not like home
