new construction - water heater help!
We're working on plans for a new home (hoping to break ground this Fall), and need help with our water heater "plan". Our builder has gotten one (plumbing) bid so far, which included 1-50 gallon hot water heater, and an optional recirculating line.
We have this set-up currently (without recirculating line), and don't find it meets our needs. (We "lose" the hot water in our master shower if water is running anywhere else in the house.) We're a family of 4, with 2 daughters ages 4 and 7 - so will definitely be needing more hot water as the years go by :).
Our new home will be a 3200 s.f. ranch, with master bath, girl's bath, and powder room on 1 end, and kitchen, laundry and a second powder room on the other. (For reference, current home is a 2600 s.f. ranch, with centrally-located kitchen and laundry, master bath on 1 end, and girl's bath/powder room on the other.) Both new and current homes will have a basement (guest) bath, with infrequent use. Both will also have master bathtubs with infrequent use (albeit higher in the new home, as we've selected a smaller soaking tub), and two showerheads in the master shower, with 1 used 90+% of the time.
We would be interested in a tankless system, and would love any insight into how well it might work for us (we live in central WI, and have (cold) hard well water, which we soften). If we went this route, would it be best to have two tankless units at opposite ends of the house? Or would 1 tankless unit with a recirculating line suffice? Alternatively, what "tank" setup would you recommend?
Thank you in advance for your help! We'll obviously be seeking additonal plumbing advice and bids, but would appreciate any and all help you can provide!
