Point of Use Hot Water Heater Questions
Hot water travels about 60 feet from the tank to our upstairs bathroom and it takes too long to get there. I'm thinking about installing a point-of-use heater with a mini-tank but don't know if it will do what I want. Can I install a 2.5 gallon POU heater in the hot water supply to the bathroom and expect both immediate hot water from the POU heater and a reasonably seamless switch to the hot water from the central HWH when it gets there? There's about a half gallon of water in 60 feet of 3/4-inch pipe. There is not currently a tub or shower in that bathroom (I took out the old clawfoot and have not replaced it) but there will be so I don't want to make the POU heater the only HW source.
Google couldn't find anything here on this subject newer than 2007 so I'm hoping for some more recent experience.
