Count me in the ranks of those who don't like the 'instant' hot water heater. Takes way too long to get hot water in our Axis 25.5. Not only wastes a lot of water but also adds to the gray water holding tank, if you're not hooked up to a sewer system at a camp ground. Never had such problems with the old style 5 and 6 gallon water heaters in other RV's we've owned.
