I just installed a new Furrion tankless water heater. I have hot water at the kitchen sink, but luke warm at the lavatory and shower. I am perplexed as to why that is. Thermostat is set at 122 degrees (max ) and the kitchen faucet is
that temp. The other fixtures are luke warm, maybe a 98 degrees. I've let the water run, but it doesn't get any hotter. Does anyone have any insight to why i have this problem?
