Right next to it on the list
A rank or two either side of the Giant GTHPCO-45 1+GTXST-50S 1: Giant GHPCO-45 1+GXST-50TTTP 1 ($174/yr, 923 kWh/yr), then Giant GTHPCO-45 1+GTXST-50S 1 ($174/yr, 923 kWh/yr).
Within the Giant lineup
Ranked 4 of Giant's 13 certified electric water heaters, this sits between the GTHPCO-45 1+GTXST-50LBTTP 1 ($172/yr, the brand's cheapest) and the GTHPCO-45 1+GTXST-66TTP 1 ($252/yr, its priciest).
Cost over its typical lifespan
NAHB's Study of Life Expectancy of Home Components puts a typical electric water heater's service life at 11 years; run the Giant GTHPCO-45 1+GTXST-50S 1 that long and it costs about $1,909 in electricity, on top of whatever it cost to buy.
Weighing a replacement
Efficient as certified electric water heaters go, $174/year is a reasonable baseline if you're comparing what else is on the market.
Worth comparing a few current certified models before deciding.
If you're keeping it
At $174/year just to run, a electric water heater is worth protecting against an unplanned repair bill on top of that.
