Hello, I currently have a natural gas 40 gallon hot water tank running my kitchen (dishwasher and sink) as well as one full bath. I’m in the process of doing an addition which will add a second story with 2 additional full bathrooms (giving a total of 3 full baths). One of the added bathrooms is a kid’s bathroom which will have a standard shower and vanity. The added second full bath is a master bath with a custom walk in shower and a jet air tub. The master shower with body jets can use up to 8GPM and the high flow fill for the tub can use up to 12-17GPM. I’ve personally been leaning towards the instant on water heaters to potentially handle the whole house, but I’ve been warned that the flow as well as the capacity could present a problem in this setup. It’s been recommended to me to use a 80 gallon water heater to be able to fulfill the 50 gallon reserve requirement for the tub but this to me seems like a waste of energy as well as maybe needing a second 40 for the rest of the house?!?! And this recommendation has come from a plumber that is a friend of the family. In my recent research should I maybe consider one, two or three instant on gas water heaters (maybe piggie back two together for the flow potential for the master and one to handle the other 2 full baths). Or might it be in my interest to use a storage tank of some sort associated with them?!? I’m open to all recommendations as I’m not as familiar with the instant on water heating systems. For heat I have forced hot air in case any of that matters.
Odds are there will only be 2 showers on at the same time ever given a family of 4 with 2 kids. Thank you in advance for your replies! This site looks great and very useful!!!
Also forgot to mention that I'm located in Massachusetts for weather reasoning in case this matters.
