Some information about this unit (and the entire product line) is sparse, and numerous people have posted inaccurate information as well. First, RTFM. EcoSmart provides a wealth of information online, and all of us would do well to check their site before posting bad information.

I have two of these units, one for DHW (Domestic Hot Water) and the other to operate our whole house hot water baseboard system. Some information is hard to find, and other information is a closely guarded secret and cannot be obtained anywhere online. I'll focus on these areas.

The unit is rated at 27KW at 240 volts. Internally, it is three separate 9KW heaters, operating in series and in sequence based on demand. The unit is truly self-modulating and will not provide more heat than the load requires.

Each individual heater requires a dedicated 240 circuit, rated at 40 amps, and provided via #8 wire. For the Ohm's law fanatics, each unit draws 37.5 amps under full load, for a total system load of 112.5 amps. Anybody that tries to operate this unit off of a 100 amp main breaker deserves what he gets. We have ours connected to our main 150 service, and can get away with it because everything else in the house is "green" and we can operate everything else with the 37.5 amps available if the heater is running under full load.

I'll say this again: Each internal unit requires a separate, dedicated 240 volt 40 amp circuit, equalling a total of three separate #8 wire 240 volt circuits. I hope I made that plain enough.

The heat exchangers inside the heater are 3 copper pipes, cross connected in series with about 1/2" dia. copper sections. So there is a flow restriction, but nothing as radical as some of the reviews would have us believe.

My electric tank-type water heater developed a leak, and after a lot of reading on the Internet I decided to replace it with a tankless unit from EcoSmart. I'm fairly handy, so I wanted to do the work myself. I bought the heater from Amazon for $453 and various electrical and plumbing supplies from Lowes and Home Depot for $251, for a total outlay of $704. Aside from the tankless unit, the biggest expense was the wire.

Tearing out the old tank heater was easy and only took about a half hour. Mounting the EcoSmart unit in the same place as the old heater and creating the new plumbing connections with copper pipe took about 4 hours. Although 240-volt wiring was left over from the old heater, the 12-gauge wire was too thin, and there was only one 30-amp circuit available. The EcoSmart unit I bought needs three 40-amp circuits and 8-gauge wire. My breaker box is located about 30 feet away from the water heater location, so I had to string 3 lengths of 8-gauge, 2-conductor wire up into the ceiling and across to the breaker box. This took a full day, and crawling around in the space above the ceiling killed my knees. My electrical service is 200 amps, so I only had to find 3 double-wide slots for the new circuit breakers (one slot where the old water heater connected, and two new slots). Shuffling a few breakers around gained me the last 3 available slots. Hooking up the EcoSmart unit was simple, and the instructions are very clear. The biggest hassle was routing the heavy 8-gauge wire into the breaker box. Doing the electrical hookup took about 3 hours. After verifying that nothing leaked and all the voltages were right, I turned on a hot water tap and prepared for the worst. And Voila! Hot water. Lots of hot water.

We went through a bit of a hassle to get this installed professionally and properly; however, it was worth every bit! What I think Amazon needs to stress is that when a consumer is trying to determine what size unit is best for their home, the main, determining factor is the INLET WATER TEMPERATURE in your home, based on your geographical location. We live in Michigan, in the lower-thumb area on the East side. In the winter, our inlet temp is just above freezing, 38-40 degrees! Therefore, there is no other Ecosmart unit besides this one (27) that will work year-round here. This was a learning process for us. We originally bought the (11) model and had that one installed and it actually worked pretty well for all outlets upstairs; however, all outlets in the basement, where the unit is installed, just didn't have enough time to heat up before reaching the faucets because the inlet temp is just too cold here. SO, as a result of having to swap-out units to the larger (27), we did have to upgrade our electrical in the house from a 100 breaker box to a 200. This is obviously very pricey, but a good investment, nonetheless. I am lucky enough to have two very good friends who are licensed - one plumber & one electrician. Ecosmart does require the installation to be by licensed contractors in order to honor the lifetime warranty on the unit. We have seen a decrease in both our electric bills and our gas bills, on top of the increase in the value of the home by just having this system. The warranty is even transferrable to one subsequent homeowner! What a great selling-point if you intend to move at some point in the future! The only adjustment we have had to make is that now we have to let the water run for an average of 20 seconds before its hot; but, once it is, we never, ever run out! And, in a house with 2 adults and 2 teenagers; that, is priceless!!
