THIS IS THE FUTURE OF HOT WATER
Style: ES-18KW(Ver.B)
This is such a killer water heater!!! Tiny, easy to install, gets water hot AF. Affordable and makes more than enough hot water for a 3 person household.

Works perfect for me.
Small two bedroom one bath house and I am the only occupant. Propane water heater costing me wasted money on heated water I never used. Upstate New York. Very cold water even in the summer as I’m only living here April through November. I had set my water pressure at 70 psi and this tankless water heater was not working properly. Reset my water pressure at 48 psi now it works perfect. I can now take a shower with 115° heated water for as long as I want. I had room on my electrical 150 amp panel as I am using a propane clothes dryer. Two pole 40 amp breaker worked perfect. If you have a small residence with up to three occupants, this unit would probably suit your needs.

Well made, easy to install
Style: ES-9KW(Ver.A)
Update: We have been using this water heater for over a month now and are still very pleased with it. Water is always hot, and our electric bills are even much lower. We installed this to provide hot water for a one bedroom “tiny house”. It was easy for my husband to install and the included directions were simple to follow. The heater attached to the wall under the kitchen cabinet, and with the low profile it fit perfect. There is no issue running hot water in the kitchen sink, with someone in the shower. I’m thrilled with my purchase and its capacity, to provide enough hot water for our needs.

Inconsistent Temperature
Style: ES-18KW(Ver.A)
Easy to install and adjust. However, the temperature of hot water fluctuates quite a bit. It has trouble modulating to the exact temperature and seems to varies 7 degrees. It’s unable to maintain an exact temperature. Really frustrating when taking a shower
