Best Tankless Water Heaters for Large Families
Consistent hot water output, 82% thermal efficiency, commercial and residential settings, digital controller included, good flow rate, LP and natural gas-powered, sealed combustion system, and safety elements are built in for your protection.
Slight hot water output delay and installation is tricky.
Hot Water Output: This gas-powered water heater is able to deliver as much as 7.5 gallons per minute—an output almost on par with the Takagi heater. However, though it doesn't quite match the Takagi's 10 GPM output, it delivers much more reliable and consistent heating.
You get a short delay (30 second) before the hot water hits, but once it's on, you'll find it stays consistently hot throughout your shower. The high output means you can run two or three showers and sinks at once without overtaxing the heating system.
Reliability: The heater is designed to be highly reliable, with heating elements that can produce anywhere from 10,000 to 180,000 BTUs. The commercial and residential settings will allow you to adjust the heater according to its location and use. With an 82% thermal efficiency, it's a highly reliable heater that will help you to conserve energy—both LP and natural gas, according to your preferences.
The heater is surprisingly compact—just 14 x 23 x 9.3 inches—so it can be installed in any home or apartment.
Features: The digital controls allow you to raise or lower the temperature easily, and you can set it anywhere between 98 and 160 F.
The system is a bit tricky to install, so it's recommended you use a professional electrician or plumber to do the work for you. However, once it's set up, you'll have no trouble using it. The built-in safety controls will prevent the heater from overheating, protect it from frost, and even reduce the risk of an electric power surge damaging the heater.
Price: At close to $940, this is on the pricier side of the scale, but definitely worth owning if you have a large family (5+ members) that uses a lot of hot water. Thanks to the consistency of the hot water output, you'll never have to worry about cold showers again.
