Pas satisfait n’est pas performant chauffe avec un très faible débit d'eau,le contrôle est au maximum à 140. Très dessus?

Es la segunda vez que tendré que sustituirlo por garantía. Lo peor es que ni siquiera vivo en un lugar frío.

Excellent chauffe eau pour un plancher radiant au glycol.Très bon rendement et très fiable .

Pressure is weak and make some noises. I don’t recommend

I put this in line with my central water heater because my kitchen sink is a long way from the central heater. This definitely provides hot water within seconds when I use the tap now. Only have it connected to the kitchen tap and it keeps up no problem. Wanted to put in a small tank under the sink, but did not have space available. This unit is slim and fit in well.

So far, it's been a great heater!I have an old house, and the electric company only provides 75Amps to my house.With my old heater (11kW), the lights would flicker, as it would chop and suck the line dry (especially when combined with the 15Amps AC working at the same time).The old heater (11kW), would heat the water full power for a fraction of a second, and the remaining time use no power at all.This caused power throttling; led lights and ac capacitor blew quickly.Also, in summer the water was burning hot; no way to control the heat.That's when I knew I needed another heater.This new heater does not flicker the lights. I think it uses a more continuous stream of energy. No chopping frequency, no sucking dry the power line at 10x per second; just one smooth functioning.It also has a temp gauge, and at 100 degrees F, it provides sufficient warm water (slightly warmer than 100F), to take a shower, or wash your hands. 105F gives pretty hot water, only suited for dishes.It's noiseless, turns off immediately when the tap is turned off; and my next electric bill will tell me how efficient it really is!It works great for Florida temps so far; feeding one tap, and one energy saving shower head at the same time.Winter is coming up, and I'll write an update on my review, how it will warm up the water then.

I read many reviews of this water heater before buying it. One common complaint was that the water heater leaks. When I first installed it, I did have major leak at the threads which connect to the flexible hose. Another quarter turn of the wrench and problem solved! The other problem is that the instructions say to use flexible water heater hoses. That would be fine except that this model has 1/2" connectors and not 3/4" connectors. I used regular 1/2" hoses and connected to 1/2" pex. I also installed a cutoff valve on the cold side.I did have one hiccup. When I installed this, I had not put the final mixer in the new shower valve body. Instead, it still had the plug which keeps it from leaking. However, hot and cold water can intermingle when the mixing valve is not in there! The first time we tried the hot water in the sink, it wasn't too hot, but had moments of scalding hot and moments of almost cold. Once I installed the valve in the shower controller, all of that went away and we have water hotter than we could shower in!I installed this is a guest room which is not part of the central house. Therefore, only the shower and bathroom sink are running off of this. I do not think it would do more than that. However, it is perfect for our use! We have a water well and the water is fairly cool, so it can get the water more than hot enough for a shower. Currently, our well house is not insulated, but we plan to do that before winter comes.

I (late 40's, mechanically-minded woman) just installed this unit in our home. Installation not too complicated, this replaced a 50-gallon tank water heater. Servicing two sinks and two appliances, (kitchen, 1/2 bath and laundry room) I sized this item to the available electrical supply, as I did not wish to incur the extra expense of additional wire and another circuit breaker. Existing wiring consisted of one double-pole 40-amp breaker and sufficient gauge conduit. Since this unit is supplying a dishwasher, washing machine, kitchen sink and bathroom sink, none of which would be likely opened at the same time, I figured this unit should be more than sufficient.So far, so good. Did not experience the leakage problems with the compression fittings others have noted, I think these fittings simply require a gentle hand. I did have to make adjustments from 3/4" supply lines down to the 1/2" necessary for this unit; the downsized pipe acts as a self-restrictor of sorts, slowing down the water flow to allow ample heating of the water before it exits the heater.I also installed an inline scale inhibitor filter, Aqua-Pur AP430SS, so reconfiguring the plumbing was necessary, as well as the addition of two 1/4-turn ball valves. (Highly recommend replacing the crappy spigot-handled gate valves that are typically installed with original tank water heaters, these things rarely actually completely shut off the water supply to the heater, especially in an emergency or during maintenance.)This was also my first attempt at sweating copper pipe and fittings, and after a few tries, achieved success with leak-free connections. Hubby seemed impressed that I did not burn down the house... although I don't think he really was confident in allowing me to play with the blow torch.A word of caution, as others have mentioned, the manufacturer stipulates installation by a professional plumber, (name and license number required on the warranty registration card) or apparently that 'lifetime warranty' is voided. That is disappointing, but if installation will cost more than the appliance, (as is common) sometimes you gotta do what you must. Did spend additional funds for the sediment filter, copper pipe and brass and copper fittings, and flexible SS supply lines, (highly recommend Falcon Industries' hoses, although they're made in China,) but estimate I saved a minimum $300.00 on installation, probably more.Be careful with the compression fittings, enclose your electrical connections inside a lidded junction or outlet box, and purge the line for a few minutes to ensure all air has been removed prior to turning on the heater, and you should be good to go.I do like the simple knob control, which allows precise selection of output temperature, and the fact that the unit can be turned on or off without having to mess with the breaker panel. This is handy when changing out the sediment filter, or for other non-electrical maintenance.It will be interesting to note the difference in the next electric bill or two; this is the second tankless electric water heater we've installed in the house. (Purchased previous unit on Amazon, see my earlier reviews for that unit.) After the first one about eight years ago, the following month's electric bill was about $30.00 cheaper. Eagerly anticipating the next one to see if similar utility savings will be realized. Also have plans to utilize the newly-found storage space in the corner of our garage that was formally occupied by the old water tank.
