Looking to install a new water heater for my 1000 sqft 2 bathroom home with 3 adults. No gas pipe near by and limited space for required clearance anyway. I've been reading a number of threads about 1 large water heater vs 2 smaller ones. I think most of these threads assume the same heating element and voltage with the only difference being the tank size.
My question is this. Would it be more efficient and faster recovery to use 2 120v 30 gallon units installed in series or just get one 240v larger size tank (not sure of the size I need yet. 3 showers in the morning before work). I might be completely off base here, but I'm assuming I can achieve more efficiency by putting one of the heaters on a timer so it only turns on during the high demand shower times.
Last thing I have gas in the building, but the changes to framing, running the gas pipe, and venting would probably cost more that I could recover in a reasonable amount of time from the savings in switching. Am I right in assuming this?
