On the specs say is for indoor, can install outside the house but with a roof???

Asked by: M3
Only if the outdoor temperature never goes below freezing. The water in the line will freeze and the unit could burn out.

220-Volt Self-Modulating 18 kW, 4.4 GPM Multiple Points of Use Tankless Electric Water Heater is rated 3.8 out of 5 by 35.
Rated 4 out of 5 by from It works in Monterey Easy to install. I figured out how to do the 220 wiring installation on YouTube. The temperature here is usually between 50 and 70 degrees. It heated the water well above what was comfortable when the water temperature was below 60 degrees. I purchased this heater because it was recommended to me by someone who lives in this cool climate and installed it in a 3000 square foot house with good results. My only complaint is that the temperature tends to fluctuate. That can be very irritating when you are taking a shower and the water goes cold or way too hot. I think I have the problem solved Now by setting the thermostat at a lower setting.

Rated 4 out of 5 by from Good Choice to a standard waterheater The product performs perfectly as described....but. A couple of things could have been better explained in the description and there is a way that it performs better that varies from what people used to tanked water heaters are familiar with. If you are pre-preparing for its arrival you need to know that it IS 100amps, but that it is two double pole 50amp circuit's, so that's four power wires and a ground. And when you're running it don't set the temperature to the maximum or it will cycle through "over heating" a lot. Set it down one notch and it works perfect. And when you run a shower, turn it all the way up for a few seconds and then down to where you normally run it. it will heat up faster that way. Remember this is not a tanked water heater, so there are different rules. Other than that, which I consider part of my learning curve, it is the best decision I've made for home improvement in quite a while.

Rated 5 out of 5 by from Best heating! This is a great heater: I can set up the output temperature and no matter the water flow it keeps heating the water at the same temperature! We could run 3 showers at the same time, which is a rare occasion but we needed one as the whole family had to go out and the water heater kept the heating capacity just fine! It was easy to install as its size fitted so well that we saved space for other stuff we wanted to keep in the closet. Definitely recommend it.

Easy to install, 3/4 connectors are the only way to go! This met all my expectations for quality. Very stylish in design. Best of all, hot water when I need it, not a 50 gallons of water that might of heating all night, day or even a weekend. I'll update this later on savings on Electric.

My water pressure is pretty low to begin with but I still needed to choke down the inlet to get the water up to set temperature. This is for a single bathtub at considerably less than 5 gallons per minute. Not a huge hardship but it was disappointing..

Rated 4 out of 5 by from Different but awesome This product is great but different from a traditional water heater. In coming water temperature and how much water demanded on output all play factors in the heating so I can see how this product may not heat as well or as fast in colder climates but for south east Georgia it has met all expectations. Unlimited hot water is definetly a luxury and at the same price as a tanked water heater it will also save you money. I had the larger wire and breakers done by a professional electrician but ran the plumbing myself and didn't have any problems. In my opinion it's a smart buy we will just have to see if it lasts the lengths of time.
