The Eccotemp ET-32 Electric Tankless Water Heater is used in demanding applications where incoming water temperatures or total flow requirements dictate more power than the ET-14 or ET-22. This high-end Electric Tankless Water Heater is a residential model for whole house water heating. The Eccotemp ET-32 Electric Tankless Water Heater is ideal for use in light commercial applications such as offices, specialty restaurants, convenience stores, salons and Pet grooming shops. This on demand electric tankless water heater is a powerful replacement for traditional storage tank type water heaters.

Customer Questions & Answers

Watts or Kilowatts usage

I am wondering how many Watts or Kilowatts this unit uses per hour of use.
Asked by: Sarah
it says 133 amps and 220 volts =29260 watts * 29.26 KW = 29.26KWH / hour. It only uses significant power when the water is running. It only uses as much power as required to raise the water temperature from what ever to the set point temperature up to a max of 29.26KW. Given 4.0 GPM = 32 lbs of water per min. given input temp of 55 and out of 105 = delta T of 50 degrees F 50 F * 32 Lbs= 1600BTU/min. = 96000BTU/H Given 3.412142 BTU/hour = 1 watt then 96000BTU/H = 28134 watts or 28 KW and if you took a 1 hour shower like that you would use 28 KWH of electricity. I get my power at $0.11/ KWH so it would cost me about $3. Not many showers run 4 gallons/min. I hope that helps.

Customer Reviews

4.0 GPM Electric Tankless Water Heater is rated 1.0 out of 5 by 1.
Rated 1 out of 5 by from you get what you pay for Bought this unit because our old tank style water heater wasn't keeping up anymore and wanted to try tankless for its endless supply of hot water. Opened the box and started reading the manual and that is where the first disappointment was. The manual fell short on how to install the unit specifically how to wire it. The information was scattered over the entire manual, as far as what breakers to use and what wire size. In their description for the breaker amps they gave you how many amps for a 6 wire hook up which totaled X amps, then for the 4 wire hook up it was a different amp rating, and if that didn't confuse you they told you the max amps for the unit which was a different number again. As for the wire size in the main wiring section of the manual the tell you to use X size wire, but all the way at the end of the manual they tell you casually to use a much bigger wire. Moving on to the next subject the main cover of the unit, nice big piece of plastic not a let down but it covers the temperature adjuster and the status light, so you can't easily adjust the water temp or see the status of the unit. You have to go to the unit remove the 8 screws that hold the cover on and make your adjustment or check its status. How hard/expensive is it to make these things accessible with out removing the cover. Next subject, so after we figured out the install and everything and got it up and running during use the water temperature fluctuated regularly even at a low flow rate don't know why. I'm not sure how these work but to me the heating elements should stay on at a consistent intensity to heat the water to the set temperature not turn on and off like a roller coaster. Now for the main problem with this unit, after 2 weeks of being installed and used the unit completely stopped working completely!! 2 weeks can you believe that $500 and you only get 2 weeks of use. Upon the unit failing it beeped a trouble code in order to tell what's wrong with it, however the trouble code is useless because no where in the manual or anywhere on the internet are the trouble codes defined. That leads me to the next issue customer service! I filled out the online support request where they asked for the usual information who you are, what unit you have model serial etc and what's the problem. The next business day I received a reply, requesting proof of purchase, serial number (which I put in the online form) and pictures of the install? really why do you need pictures. At the end of the email they say until all this has been submitted your case is closed and considered solved! REALLY you don't even ask any question and find out the particulars of the problem, all you want to know is if it is still under warranty so you don't have to fork out the money to fix your faulty piece of junk. So then I called the customer service number to talk to a person, got somebody in India who said I will transfer you to a tech person which was funny because in their phone menu I picked tech support? They connected me to a tech person who of course didn't answer the phone so I left a message. An hour later no call back, called again still no answer, another hour called again voicemail again left another message, never did get a call back. Called the main tech support line again back to India got a person and told him the issue so he put me on hold so he could go find an answer to what the trouble code means, (why didn't he have access to the information being he is tech support?) 10 minutes later after being on hold he comes back and tells me the what the code meant and gave me a few things to look at, never mentioned anything about a service tech coming out to look at it or anything, just wanted me to do it. I'm not a service tech, I'm a pretty skilled DIY guy but come on I didn't build or design the darn thing, I don't know the ins and outs of the unit send a qualified tech out here to diagnose/ fix it!! Anyway I tried the things I was qualified to do and it still didn't work. The customer service guy told me I could also send the unit back to them for an exchange and be without hot water for a week or 2 and then who knows if the next unit will work any better. So this was a terrible experience not worth my time and money, will never recommend this product or company to anybody EVER. I returned the unit to the store and bought another tank style water heater from a more reputable company and now I have consistent reliable hot water again.
