Re: Hot Water in Bathrooms
While Z is correct in the speed to become hot let's analyze the physics (or would this be geometry?) of it all. If you have, let's say, 34 feet of pipe between your shower and the hot water tank you need to empty (waste) that 34 feet of 'coolish' water before getting the hot stuff. What I had recommend was to brush your teeth in the sink using the hot water that is 'coolish' and thus not wasting it too much. Or use it to fill a glass to take some meds, or use it too fill the dog bowl, whatever you can use the first 34 feet of 'coolish' water for.
A tankless hot water system will make NO difference in how those 34 feet of pipe to the shower are handled. Unless of course you installed the tank (or tankless) closer to the shower.
