Details

Hot Water Output: This hot water heater can deliver anywhere from 2.6 GPM to 5 GPM, depending on how cold the climate and how hot you want your water. With its 24 kW heating system, it delivers a surprisingly steady stream of water. It can handle up to 150 psi, but the water pressure will be minimally affected by the heating process.

With heating temperatures between 80 and 140 F, it will deliver all the hot water you need for your sinks, dishwashers, and showers!

(Note: The output is insufficient for high-flow fixtures, but perfect for low-flow faucets and showerheads.)

Reliability: This is one of the most reliable tankless hot water heaters, though it requires heavy-duty electronic components. It runs off two 60-amp circuits, and may require an electrician or plumber to install it properly. Once it's installed, however, you'll find it can handle a lot of regular use—it's even built to be resistant to earthquake damage!

It's also one of the most energy-efficient water heaters on our list, with a 240-volt, 1,440 watt operation. If you have limited space, this compact water heater—21.5 x 19.5 x 8.8 inches—is exactly what you need.

Features: The heater comes with built-in auto-modulation controls, which will regulate the hot water output automatically. The Advanced Temperature Controls will keep water temperature consistent as you shower, and you'll find the digital heating display makes it easy to set and adjust the temperature to save energy or increase the heat of the water. It runs totally silently, and there is no need for venting!

Price: At $700, this is getting toward the pricier side of the scale, but absolutely worth it if you want reliability and user-friendly operation. Plus, with the 7-year leakage warranty and 3-year parts warranty, you know it's a quality appliance!
