tankless water heater questions

It will work great for solar or any way that you have pre-heated water entering the unit. It will only heat as needed.
I have a 5 year old SETS tankless. It is not a very good unit. In the winter the really cold water causes it to constantly heat too much then not enough. In the summer it is great due to the higher incoming water temp.
If I had a solar batch water heater or something else to preheat the water, it would work fine all year. Planning on making one soon.
