Single Point 2.4 kW 120 Volt 0.3gpm-2.0gpm Electric Tankless Water Heater is rated 2.1 out of 5 by 9.
Rated 2 out of 5 by from It's warm, but a pretty piddly little stream of water for it to be so. OK, I've now had this running for about a week.... And, I think I see the main issue when you're considering purchase of this In-line Heater is in being able to determine if it can get hot enough for your needs. The problem is, just how much water is 3gpm, or 1gpm, etc? So, here is what I found out after installation: The water coming from my faucets without the In-line Heater is pretty cold... probably around 50 degrees, I'd guess... It's cold enough that it's uncomfortable to wash my hands in. In the Guest Bath where I installed the In-line heater, as long as I turn the faucet down to a stream of water that is about the size of a soda-straw or smaller, I get water that is comfortably warm... not hot.... but warm enough for comfortable hand washing. If I turn the tap open more than that, it gets colder and, from the water temperature, I wouldn't even know the In-line heater is there. If you're OK with a stream of moderately warm water the size of a soda-straw, you'll probably be OK with this device. I do think it's way overpriced for what it does. But since, in my house, it takes about 3-4 minutes to otherwise get hot water in that Guest Bath... and the In-line heater delivers it instantly (in enough volume for hand-washing), I'm going to keep it... Clean,warm hands instantly is still better than clean, cold hands.

Rated 1 out of 5 by from good quality construction...very poor performance. product is not capable of keeping up with the normal flow rate of the average home. the flow rate has to be turned down so low that it is of little value in everyday use....might be o.k. in an emergency situation where you were on generator power, or in an rv or similar situation. thumbs down on this item for everyday use.

Rated 5 out of 5 by from Those who've criticized this product have clearly unrealistic expectations Let me start out by saying if all you want is faster hot water, or investing money or making modifications is an issue such as with living in a rental, try a hot water recirculating pump instead of a tankless heater. Often they'll only result in a slightly higher electric bill for the convenience of instant hot water, and they only require installing a few plumbing fittings and plugging in to an outlet. Moving on then. Tankless water heaters are available with an array of specifications. This is the cheapest, lowest wattage unit carried by this store. It has its uses, but if you're looking for something to replace your 50 gallon, 10,000 watt water heater you're not going to get it on the cheap, you're going to need to study the specifications of many units, and shell out more money. Think about it, why would a company like Eemax make 2.4kw, 3kw, and 3.5kw 120v units all of the same size and price? The answer is so they can have a heater to accommodate the number of different 120v wiring situations people are going to have in their houses and places of business. Tankless heaters come in many capacities from 1kw 120v, to 38kw 240v and beyond. My hot water takes for ever to reach all my faucets. My water bill is already ridiculously high, I'm not about to dump 5 gallons down the drain every time I need to wash a dish, so I've adapted to washing my dishes with a trickle of cold water. Given this, I can tolerate a trickle of lukewarm or warm water. I switched to a low 1.6 GPM faucet with a strong spray at very low volumes, so I expect this unit will suit me fine. For the time being I'm going to sacrifice my garbage disposal outlet for this heater. Given the disposal is on a dedicated 20A circuit and it's a relatively new house, I can use this unit, but it's as high as I can go without running another circuit, so like it or not, a small stream of warm water is all I'm going to get. I may splurge and run 240v to the 2 bathrooms using the breakers that will be freed up by removing my closet water heater. I'll probably need a 12kw+ unit for a comfortable shower (1.5 gpm shower head, again with great pressure at lower volumes), but given my current water heater accounts for about $50 of my electric bill, the install will pay for itself in 1-2 years. Any way you slice it, that is a very fast return-on-investment for a home/energy improvement project.

Rated 1 out of 5 by from Only slightly warms water if left at a trickle Basically this concept does not work. Need a tank or 220 to get enough power to heat enough to notice. A 110 unit just can't perform. It was hard to figure this out from the product info available.

Rated 1 out of 5 by from This is a worthless model of a good product I have used other Eemax products and found them to be good. Bought this low-end model for a very cost-conscious customer and installed it myself. It only raises the cold water temperature 10 degrees, which is barely noticeable. Had an electrician confirm my work and it was proper. He said cheaper units are pretty worthless, and he was correct. I would never do the same again.

Rated 2 out of 5 by from Luke warm water at best.... This tankless electric water heater puts barely warm water at best. If that's all you need than it would probably work for you.
Date published: 2015-01-06
Rated 5 out of 5 by from Tankless water heater Easy assembly to have not checked the heating capacity at a 1.2 gpm flow yet but I believe that it will be fine.
Date published: 2015-10-20
Rated 1 out of 5 by from Not worth it. Not worth the money it was not clear in the online directions that there was no pressure for a shower.
