Think about it: The way most households in this country heat water is absurdly wasteful. We fill up big 40- to 50-gallon storage tanks, then pour energy into them 24/7, year in and year out, to make sure we have hot water at the ready whenever we want it. But often it doesn’t work out that way. If a teenager takes a long shower, or a spouse settles in for a tub soak, there can be a long wait for that emptied tank to reheat. Then there are the nagging worries: Is it filled with energy-robbing sediment? Will it spring a leak? Both are reasonable concerns, as tanks generally fail in 8 to 12 years.
These are the arguments for investing in a tankless water heater. It generates hot water only when you need it—and for as long as you need it—saving 27 to 50 percent of fuel costs over tank-type heaters. (A typical gas-fired tank wastes 40 to 50 percent of the fuel it burns.) And because there’s no tank to fail, there’s almost no chance of a catastrophic leak. What’s more, since their introduction in the United States in the 1990s, tankless heaters have become increasingly sophisticated, with features like built-in recirculating pumps (for “instant” hot water), and wireless connectivity that tells you via smartphone exactly when a unit needs maintenance.
HOW MUCH DO THEY COST?
Prices range from about $170 for small gas-fired units to more than $2,000 for high-output heaters that can supply two showers at the same time; $1,000 is about average. Tankless electric heaters run between $90 and $900. First-time installation costs run more than a simple tank replacement. (See slide 9 “Install It Right”)
HOW LONG DO THEY LAST?
Gas-burning tankless water heaters should operate for 20 years or more, two or three times longer than tank-type heaters. Tankless electric units have shorter life spans, on the order of 7 to 10 years.
WHERE TO BUY THEM?
Plumbing-supply stores, big-box stores, and online retailers all carry these heaters. Or order one through your plumber.
WHO INSTALLS THEM?
This is definitely a job for a pro, as it involves making leak-free water, vent, and gas connections, in the case of gas or propane units, or upgrading the wiring and circuit-breaker panel, in the case of electric units.
HOW MUCH MAINTENANCE?
Sign up to have a pro provide annual service, including cleaning or changing water and air filters and checking the burner. In areas with hard water, a vinegar flush every 500 hours keeps mineral buildup—scale—from clogging the heat exchanger. That 20-minute task can be done by either a pro or a homeowner.
