Customer Questions & Answers

When it says 11 kw, what does that mean - 11 kilowatts per hour?

Asked by: KansasGirl
11 kW is the maximum amount of instantaneous power the unit consumes. If it consumes 11 kw for an hour it would have consumed 11 kWh of energy. When you're sizing the electrical for one of these you need to size the wiring and breakers to accommodate the power so, with a 220 volt service, an 11 Kw unit would consume 11,000w/220v = 50 amps. Because the world isn't perfect the system should be sized for 60 amps.

It says 1 x 60 amp

It says a 1 x 60 amp. Would a 2 x 30 amp work?
Asked by: Specialsnowflake
No. It requires a double pole 60amp breaker.

Would this model be able to support kitchen/bathroom sink and a washer? Not all running at once.

Asked by: James
I installed this exact same model in a townhouse almost a year ago. The resident has two teenage daughters and they have never ran short on hot water. It is a 3 bedroom 2 bath (with 3 females) and this model handles two showers, the washing machine, and a dishwasher all at the same time. We purposely tested under extreme conditions upon the initial install. You'll be more than happy with this tank-less water heater! In fact, I'm getting ready to remove two traditional water heaters for two separate apartments and install a single tank-less heater.

11 kW 2.14 GPM Self-Modulating Electric Tankless Water Heater is rated 3.9 out of 5 by 55.
Rated 5 out of 5 by from Good water heater This water heater does everything they say it would. It heats 2 gals/minute to the set temperature. Only flows 2 gals/min, so don't buy this size you need more flow.
Date published: 2016-08-30
Rated 5 out of 5 by from Works great as a water heater, but a slight issue in some applications Installed easily, small size fits well, heat setting is dead on accurate as measured at sink or shower, uses switch mode (PWM) triacs to regulate and stage heating elements so uses only the amount of power to regulate temp at any flow rate and does it well. At 11kw max it uses only a little bit more power than a standard tank water heater but only when water is heated, does not come on at random intervals to keep water in a tank hot, so actually uses way less power. The only problem with this and any modern unit of any brand is that the PWM method of controlling the heat elements causes massive amounts of EMI (electromagnetic interference) to be generated, radiated, and fed back up the power lines, so if You are an amateur radio operator You will get noise when someone turns on a hot water valve in the house, and if You use it in an off-grid power system some smart inverters like the Outback series will go crazy because the noise interferes with their CPU clock and power monitoring systems, which are the 2 problems I have. I fixed it by using a seperate dumb inverter to run the heater and prohibit the use of hot water during a QSO on the radio. Problem solved, great device ;-)

Rated 2 out of 5 by from Inconsistent and Unreliable Stability of water temperature is very poor, with constant water flow the temperature would cycle from cold to scalding, necessitating caution and constant adjustment. After about a year the water would not get hot. The outlet thermistor was bad. I contacted the company and I had a big issues with warranty repair because I didn't register the product. They reluctantly gave me two thermistors to replace the ones in the heater. The water heater worked again but the inconsistency remained. Eight months later and the water temperature is barely over 100 F. Bad thermistors AGAIN. Now I have to find new themistors!!! I am done with this product.

Rated 5 out of 5 by from Seems good! My small Rheem tankless water heater has a 4 yr lifespan. It stopped working. I got this brand. It's definitely superior in water pressure and how hot it gets wAter. It works in my 3 person home great. Let's see how long it lasts. Replacing one of these is the xpensive so at the end of the day it's. It more effective than the tank one. I find it more convenient though.

Rated 5 out of 5 by from Turn on when you run hot water!!! Saves space I love my tankless, it turns on when you run the hot water, it takes less than one minute to give you hot water. Love that you can dial the temp and on warmer days you can set to lower temp. And now I have more space. The only thing is that the plumber had to do the installation as it was leaking.
