Hey fellow Fanatics, we just signed the paperwork to build a new house that will be ready sometime this coming summer, and one of the things that my wife and I have been wrestling with is: do we go with the 50gal gas-fired standard tank water heater that the builder will supply, should we upgrade to a larger 75gal (~ $2600 upcharge), or upgrade to tankless water heater (~ $3000 upcharge)? Another option we would have is to add a hot-water recirculation line throughout the house for something like $1500, so we'd have instant hot water at all taps.
We have a family of 6, and the 4 kids are all teen/pre-teen girls, so showers take like 7 hours.... only a slight exaggeration there. What is everyone's experience with tank vs. tankless, and also a recirc line? My concern is that the tankless can't keep up with that kind of hot water demand, but the upcharge on the 75gal tank seems pretty high.
Would love to hear thoughts and feedback. Thanks!
