Question: Can i use this in the Caribbean where it is always hot, for shower only
Document: Next summer think I will turn the hear down & just use hot water for shower. Oh yes have 6&#34; walls with R19 & R33 in ceiling & ran all water lines inside the room so lines will not freeze & does not take much to heat the room. Also set up the bath room so we could drain all lines & put RV antifreeze to winterize the room when we go south. I do not like cold!So bottom line am I happy with the 8KW.
We bought this heater to supplement our wood stove heated water. But when it is warm outside during the day and you don't make a fire, you'll end up with a cold shower. Or when 4 people get ready in the evening the last one gets a cold shower too. I was just tired of always being the one with the cold water. This seems the perfect solution. Small, efficient (check and make sure the amps are enough for the water usage) and easy to install.
I researched all of the electric tankless heaters I could find. this one has all the new technology such as changeable thermostat,digital readout, and modulating power use. It works very smooth, and never runs out of hot water.
I read a bunch of reviews of this product before purchasing. Several warned about about leaking at the cold water inlet and hot water outlets. Compression fittings are provided and the installation instructions advise NOT to use teflon tape or paste. These fittings WILL leak without teflon. The problem is that they leak WITH teflon as well. On the advice of Ecosmart tech support, I have installed AND reinstalled these fittings three times now using no tape, a small amount of tape and more tape and have NOT solved the leaking problem.
These are the same ones as home depot, Definitely would recommend, just remodeled office with a shower and removed the tank. Works as advertised and saves space.
This product is not advisable for Northern California,  would not heat water beyond luke warm for one faucet let alone a shower valve in a very small cabin.
The bath has around 80' of wire to the breaker box so went with 8KW as only had to run one 8 AWG wire. Ecosmart says we need an 11KW in Kansas for a shower. This summer set the water at 125 & was happy. We go south for the winter but came back for Christmas & living in the room for a couple of week.
Forced into early retirement we went to work on the road have been full time RV'er for 10 years I love it more than wife. Retired again & built a barn/shop for our fifth wheel when we are home. We have a 30X16 patio with 3 9' garage doors so we have sun in morning. Also have 30X16 insulated room with bath in it with a big [60&#34; shower love it]. Wanted a tankless water heater as we are on the road a lot.
Exactly what I wanted at a good price. Easy to install, plenty of water for what I need which is a shop sink that only needs to run a few minutes at most at a time. I do have it set on the highest setting and the temp can slightly fluctuate but great for my use. I would buy it again for sure.
The heater is small, lightweight, and looks easy to install. 1/2&#34; male pipe thread inlet/outlet looks simple until you read &#34;Do not weld or use Teflon or paste&#34; and goes on to say that if you do not follow instructions the warranty is invalid. 1/2&#34; compression fittings are supplied to connect 1/2&#34; copper pipe.
Answer: yes
