There is pros and cons of doing one.A friend installed one in his and although its endless hot water it seems to really suck down some propane and getting the temperature set can be a task. He now has to go full cold and gradually open hot water to get a descent temperature.Im sure others will chime in with their advise but from what I saw so far im not interested,I have a family of four and as long as showers are staggered a bit we never run out of hot water.
