how will 50-gal gas water heater compare to 80-gal electric?
Building new construction. An option to upgrade to big tub in mstr bath comes with 80 gal elec water heater. Later, we opted to get a gas water heater since it should cost less to run. Got in the basement and saw the water heater was gas but only 50 gal. I asked about it and project manager said he'd swap in an 80-gal. Later called to say that no change would be made since salespeople claimed 50-gal gas is like having 80-gal electric. That may be true to some extent, but cost/efficiency differs from capacity. If my wife fills the big tub with 40 gal of hot water, I have only 10 gal "left over" in the 50-gal vs. 40 gal in the 80-gal. This is a 3.5 bath house and as I said the mstr has the big tub. Will a 50-gal gas heater suffice? Should I fight for the 80-gal (or 75-gal) gas? There was no indication we'd sacrifice capacity if we switched to gas.
