In my case the only way I could get hot water was to run hot water in both the kitchen and the bath. With the increased flow I could hear the unit igniter fire and the digital display showed the flame icon and a fan icon. That had not happened before.
I was aware of using only hot water and setting the desired temp. I was also aware of regulating the temp via water flow. What I don't understand still is how to increase the water flow. Am I always going to have to run both the kitchen and bath faucets when I want hot water? What about the shower?
I'm confused about the water pressure regulator. Are they a good thing or a bad thing when you have these types water heaters?
The more I learn... the less I know!
