Takagi thankless water heater.
It will provide endless hot water. Only problem is if your water has high mineral content it will cause greater need for frequency of cleaning.

Water doesn’t seem hot enough
This was installed by a professional plumber and although the water temperature is set to the max, I don’t have a hot shower.

Great
Had an earlier model that lasted over 20years without any problems. We decided to buy it again since so realiable!
