Customer Questions & Answers

Will this work to raise the water temp for my Maytag top loading washer?

I currently use only cold water for my washing. Will this produce enough hot water for my washing machine? How heavy of wireing will I need? This product is only sold on line and I want to be sure it will work for my purpose before I order it.
Asked by: Jack
No. According to the manufacturer this unit is designed for a lavatory, for hand washing. It has a max flow of 2 gallons per minute. At full flow temperature rise will probably be less than 20 degrees. This unit draws 30 amps therefore minimum wire size is 10 gauge. This information can be found on the Eemax web page.

Will this unit run a small shower in a RV?

Please hurry, I need an answer so I can order today.
Asked by: Wayne
Yes if it is a 50 amp service, possibly if it is a 30 amp service . It would take your whole power feed capacity BEFORE any device just to run the hit water heater on a 30 amp service

Electrical requirements

Will a dedicated circuit work if I replace the 20-amp with a 30-amp breaker though the circuit is wired with 12-G wire?
Asked by: Rob
Installation instructions provide needed information. The model SP3512 requires 30 amps so your electrician should be able to supply you with what is necessary. You can find this information on the Eemax web page.

Can the units be repaired?

The water co-op shut off the water and i think it burned the elements in the heater.
Asked by: Coalman
You can order replacement elements from Eemax. They come with instructions and are relatively easy to replace. I have replaced them at my Church.

Single Point 3.5 kW 120 Volt 0.3gpm-2.0gpm Electric Tankless Water Heater is rated 3.4 out of 5 by 9.
Rated 3 out of 5 by from Works ok for hand washing, but keep a spare element handy! This is my third Eemax water heater. It's used under a bathroom sink and aside from the restricted flow of the water and the 'all or nothing' type of heating you get it's ok. The first one didn't make it through my office's initial construction so I'm not sure if it ever worked. The second one lasted about 4 years, but seemed to go through elements about every 6 months until recently when it actually exploded under the sink. I'm guessing the element burned out and it must have shorted the wiring when the plastic tubes burst and let the water shoot out? It was a giant mess of smoke, soot, broken plastic and of course water streaming out from under the sink. I'm hoping that with a monthly reminder to clean out the faucet attachment, which seems to catch all sorts of sediment, and having a spare element on hand this one will last at least as long.

Rated 4 out of 5 by from Works in temporary building Had to run heavier 10 gauge wire. Low volume, but enough to wash dishes.

Rated 4 out of 5 by from Point of Use Hot Water Heater Very good for my particular needs. Used for a sink in my work shop. Only downside is the lack of a temperature control. Temp is adjusted by adjusting the outlet valve. Not a deal breaker for me. The plus side is that I'm not constantly heating a storage tank.

Rated 5 out of 5 by from Slick Little Heater This has to be the smallest little insta hot water heater I have seen, Very sceptical at first as far as performance... works like a dream.. instant hot water , takes up very little space , runs of a single pole 20 amp breaker... very happy with its performance
Date published: 2015-05-13
Rated 1 out of 5 by from Returning As long as you want a dribble of water it stays really hot, once you turn up the flow it goes cold. It should work well if you were using it with a hot water tank but not by its self. Returning.
