Hello,
I'm contemplating putting in a tankless water heater and have read the many discussions in this group closely. There is one issue that I haven't seen discussed, though.
As I understand it, a tankless unit needs to sense a minimum flow for a second or two before turning on/heating up. So if you are standing at the kitchen sink washing pots and run the water repeatedly for 5 seconds at time, do you end up getting an alternating flow of hot and lukewarm water?
If this is a real problem, would using a very small (2 gallons?) tank after the tankless unit fix this? Would it have other benefits? Would this tank need to have an electric heater on it?
Thanks, Wayne
